Accounting Firm Website Cost in the UK in 2026: Client Portals, MTD and Trust Priced in GBP

Direct answer: An accounting firm website in the UK in 2026 typically costs from £1,900 for a solid base build, £2,800 for a worked example that adds a secure client portal, Making Tax Digital (MTD) ready service pages and online appointment booking, and £3,600 fully loaded with every option in the estimator below. These are indicative market ranges only, quoted excluding VAT unless stated otherwise, and the final figure depends on page count, portal complexity, content, and integrations. VAT in the UK is charged at 20% on most website services, so a £1,900 build would normally be £2,280 including VAT, and a £3,600 build would normally be £4,320 including VAT. Always ask whether a quote is excluding or including VAT before you compare it with another quote, because a cheaper-looking headline can become the dearer option once VAT is added.

Accounting websites are not brochure sites in the usual sense. A prospective client is not merely browsing photographs or reading a slogan. They are deciding whether to hand over payroll records, bank statements, tax returns, and the financial story of their business or household. That decision rests on trust, clarity, and visible competence. A good site therefore does three jobs at once. It explains services in plain English, it proves that the firm is properly organised and easy to deal with, and it makes the next step obvious, whether that step is booking a consultation, requesting a quote, or uploading a document through a secure portal. When any one of those jobs is missing, enquiries fall away, even if the design looks polished.

This guide prices that work honestly for the UK market in 2026. It separates the base build from the extras that genuinely change the price, explains the UK-specific requirements that a generic template often misses, and shows a worked example for a four-partner practice in Leeds so you can see exactly how £2,800 is reached. It also covers timelines, common mistakes, and the questions firms ask most often before they commission a new site. If you only need a simple presence site with no portal and no local search work, you may sit near the base figure. If you need a portal, several service pages, town pages, and detailed compliance content, you should plan nearer the fully loaded figure.

What the base build of £1,900 includes

The £1,900 base build is a complete, professional website, not a holding page. It typically includes a homepage that states who the firm serves and what it does, service pages for core work such as accounts, tax returns, payroll, bookkeeping, and VAT, an about page, a contact page with a form, and a clear call to action on every page. It includes mobile-friendly design, basic on-page search optimisation, fast loading, a .co.uk domain set-up, secure hosting configuration, and a contact form that routes enquiries to the right inbox. Content is usually written or edited from material the firm supplies, with headlines that answer real client questions rather than repeating jargon.

The choice of a .co.uk domain matters more than many firms realise. A .co.uk address signals a UK business immediately, it matches the expectations of local searchers, and it pairs naturally with a Google Business Profile and local listings. A .com address is perfectly workable, especially for a firm with international clients, but for a practice whose growth comes from nearby towns, a .co.uk domain is the clearer, more reassuring choice. Either way, the domain should be registered in the firm's own name, with renewal reminders going to a monitored inbox, so control is never lost when a staff member leaves or an agency relationship ends.

Design for accountants should be calm, orderly, and confident. Clients associate neatness with accuracy. That does not mean dull. Strong typography, generous white space, a restrained colour palette, and well-organised service pages all communicate care. Photographs of the real team, the real office, and real working life help far more than stock images of handshakes. If team photographs are not yet ready, a clean design with clear credentials, professional body memberships, and plain-English service descriptions still builds trust, provided nothing on the site overstates a qualification or licence that the firm does not hold.

Cost breakdown: where the money goes

The table below breaks the indicative ranges into their main parts. It is designed to help you read a quote critically. If a quote is far below these ranges, ask what has been left out. If it is far above them, ask what extra work justifies the difference. Neither answer is automatically wrong, but the explanation should be specific, not vague.

Part of the build	What it usually covers	Indicative range
Design and build	Homepage, service pages, about and contact pages, mobile design, forms	£1,100 – £1,500
Content writing and editing	Plain-English service copy, headlines, calls to action, proofreading	£300 – £600
Search optimisation basics	Page titles, meta descriptions, headings, internal links, speed work	£200 – £400
Domain, hosting set-up and launch	.co.uk domain configuration, secure hosting, launch checks, analytics	£150 – £300
Client portal, booking and extras	Secure upload, booking, town pages, compliance pages (see options)	£0 – £1,700

Content deserves special attention, because it is where accounting sites most often fail. A page titled simply “Services” that lists accounts, tax, and payroll in three lines tells a visitor almost nothing. A page that explains who each service is for, what documents are needed, what the process looks like, how long it usually takes, and what happens next will convert far better. It also helps search engines understand the firm. Good content answers the questions clients actually ask in a first meeting: Do you work with limited companies or sole traders? Do you handle construction industry scheme work? Can you take over from my previous accountant? What do you need from me in the first month?

Making Tax Digital, Companies House, and UK compliance content

Making Tax Digital is the programme through which HMRC requires many businesses to keep digital records and submit returns using compatible software. MTD for VAT has applied to VAT-registered businesses for some time, and MTD for Income Tax is being introduced in phases for sole traders and landlords above the relevant income thresholds. The precise thresholds, start dates, and exemptions change over time, so a website must not present a fixed date or threshold as permanent fact unless it is checked at the time of writing and reviewed regularly. What a website can do well is explain, in plain language, that digital record-keeping is now the norm, what kinds of software the firm supports, how the firm helps clients move from spreadsheets or paper, and what deadlines clients should watch.

MTD-ready service pages therefore earn their £250 option price. They are not a single paragraph that says “we are MTD compliant”. They are a set of pages and supporting content that walks a sole trader, a landlord, and a VAT-registered limited company through their different obligations, links to deadline reminders, and invites each visitor to book a review. Tax deadline content also gives the firm a reason to publish regular updates, which keeps the site fresh and gives existing clients a trustworthy place to check dates, rather than relying on social media posts that disappear from view.

Companies House context matters for limited company clients. Many directors arrive at an accountant's site unsure about filing duties, confirmation statements, registered office requirements, and the difference between a dormant company and an active trading company. A website does not need to reproduce Companies House guidance in full, and it must not present itself as an official source. It should explain, in general terms, how the firm supports directors with annual accounts, confirmation statements, and record-keeping, and it should direct readers to official Companies House and HMRC sources for the authoritative rules. That restraint itself builds trust, because it shows the firm knows the limits of marketing copy.

UK GDPR and the ICO data protection fee are the other compliance areas that shape an accounting website. A firm that collects enquiries, stores client documents, and sends newsletters is handling personal data, and visitors increasingly look for a privacy notice, a cookie notice, and a clear statement of how data is used. The ICO data protection fee applies to many data controllers, with exemptions and tiers that depend on size and activity, so a website should describe the firm's approach in general terms and encourage the firm to confirm its own fee position directly with the ICO, rather than stating a universal fee as fact. The £350 option for UK GDPR, privacy, and ICO-fee guidance pages covers properly structured privacy, terms, cookie, and data-handling pages, written in readable language and linked from every form and portal login, so a client never has to hunt for them.

Client portals: security expectations and what £400 buys

A secure client portal is the single most valuable addition for many firms, and the £400 option reflects a standard, well-configured portal rather than a bespoke system built from scratch. In practice, a portal usually means a password-protected area where clients can upload documents, download completed returns, exchange messages, and track outstanding items, often integrated with the firm's existing practice software or document system. The website work covers the portal pages, the login journey, the upload guidance, the help text that explains file types and sizes, and the security messaging that reassures clients without making promises the technology cannot keep.

Security expectations for a portal are high, and they should be. Clients should never be asked to send sensitive documents by ordinary email if a secure route exists. The site should explain that the portal uses encryption in transit, that access requires individual logins rather than a shared password, and that documents are stored within the firm's chosen system rather than left in an inbox. Two-factor authentication, automatic log-out, and clear instructions for resetting access are all worth explaining in plain language. At the same time, the site must avoid claiming bank-grade security or guaranteeing that no breach could ever occur, because no honest provider can guarantee that. The right tone is careful, specific, and practical: what is protected, how access works, and what a client should do if they suspect their login has been compromised.

Portal adoption also needs behaviour change, not just technology. Older clients, clients with limited digital confidence, and clients who have always posted paper records may need a short guide, a welcome call, and a simple first task, such as uploading one document, to build confidence. A good website supports that journey with a short portal help page, a video or illustrated steps if available, and a contact route for clients who get stuck. When a firm launches a portal without that support, usage stays low and staff end up handling documents by email anyway, which defeats the purpose. Budgeting a small amount of time for client onboarding, beyond the website build itself, is therefore money well spent.

Payment norms in the UK also shape the site. Many firms now take monthly fees by direct debit or card, and some accept card payments through providers such as Stripe for one-off work. A website should state payment methods clearly, explain whether fees are fixed monthly, charged per job, or based on turnover and complexity, and avoid publishing a single fixed price for work that genuinely varies. Card and Stripe payment pages, if included, must use a trusted payment provider, must never ask a client to type card details into an ordinary contact form, and must link to clear terms. Transparency about fees reduces awkward first calls and filters out enquiries that were never a good fit.

Local SEO for UK towns, team pages, and trust

Most accounting firms win work locally. A practice in Leeds, Harrogate, or Bradford does not need to rank nationally for “accountant”. It needs to be found by people searching for an accountant near them, with a clear service and a nearby location. That is why the £250 local SEO town pages option exists. Town pages are not copied pages with only the town name changed. Each page should describe the local service genuinely: which nearby areas the firm serves, whether meetings are in person, by video, or both, what local business types the firm knows well, and how a client in that town can start. A page for Leeds might discuss limited companies and growing service businesses, while a page for a smaller nearby town might focus on sole traders, landlords, and agricultural or trades clients, if that reflects the firm's real work.

Local search work also includes the firm's Google Business Profile, consistent name, address, and phone details across directories, local reviews handled properly, and location pages that link sensibly to the main service pages. Reviews deserve care. A firm should never invent reviews, never pay for fake reviews, and never publish a testimonial without permission. Genuine reviews, collected after real work and displayed with care, are far more persuasive than a wall of anonymous praise. If a firm has few reviews, a small number of detailed, permissioned testimonials, each tied to a type of work rather than a named individual who has not consented, is the honest route.

Team and credentials trust pages, priced at £200, are the human side of the same work. Clients want to know who will handle their accounts, what qualifications the team holds, and whether the firm is regulated or a member of a recognised professional body, where that is true. Pages should list real qualifications, real roles, and real specialisms, with photographs where possible. They should not inflate job titles, invent awards, or imply membership of a body the firm does not hold. A short biography that explains what each person actually does, in plain language, reassures a sole trader far more than a list of letters after a name with no explanation.

For wider context on how UK professional service sites are priced, readers may find broader UK small-business website pricing useful, and for a comparison across the Atlantic, see how the same brief is priced in the United States. A related UK professional example is what a dental practice site in the UK typically includes, which shares the same emphasis on trust, booking, and local search.

Scenario table: choose the build that fits your practice

The static table below summarises the three headline builds so the article remains complete even with JavaScript switched off. Use the calculator in the full article package to test your own combination, but this table gives the anchor figures at a glance.

Scenario	What is included	Indicative total (excluding VAT)
Base build	Homepage, core service pages, about, contact, mobile design, basic search optimisation, .co.uk set-up	£1,900
Worked example	Base plus secure client portal (£400), MTD-ready pages (£250), and online booking (£250)	£2,800
Fully loaded	Base plus all six options: portal, MTD pages, booking, team pages, town pages, and GDPR pages	£3,600
Base plus local focus only	Base plus team pages (£200) and town pages (£250)	£2,350
Base plus compliance focus only	Base plus MTD pages (£250) and GDPR pages (£350)	£2,500

The arithmetic is deliberately simple. The base is £1,900. Each option adds its stated amount, with no hidden multipliers. The worked example is £1,900 plus £400 plus £250 plus £250, which equals £2,800. The fully loaded total is £1,900 plus £400 plus £250 plus £250 plus £200 plus £250 plus £350, which equals £3,600. If a quote uses a different structure, ask the provider to show the same addition, line by line, so you can compare like with like.

Worked example: a four-partner practice in Leeds

Consider a four-partner practice in Leeds that serves limited companies, sole traders, and landlords across West Yorkshire. The firm already has a dated site with a list of services, a phone number, and a contact form, but enquiries arrive by email with attachments, clients phone to ask about MTD deadlines, and the team spends time chasing documents. The firm does not need a bespoke system. It needs a clearer site, a secure way to receive documents, MTD content that answers repeated questions, and booking that reduces phone tag.

The build starts with the £1,900 base: a homepage that states the firm's Leeds base and West Yorkshire reach, service pages for accounts, tax, payroll, bookkeeping, and VAT, an about page, and a contact page. The secure client portal adds £400, with a login page, upload guidance, and help text for clients who are new to portals. MTD-ready service pages and tax deadline content add £250, covering VAT, income tax, and the move from paper and spreadsheets to digital records, with a deadline page the firm can update each year. Online appointment booking adds £250, with consultation types for new-client meetings, MTD reviews, and year-end planning, each with a sensible duration and preparation note. The total is £2,800 excluding VAT, or £3,360 including VAT at 20%.

What changes for this practice is not only the website, but the working pattern around it. New enquiries arrive with a service selected and a meeting booked, rather than as a vague email. Existing clients upload documents through the portal, with a checklist that shows what is still missing. The MTD pages reduce repeated deadline questions, because clients can be directed to a single updated page. None of this happens automatically on launch day. The firm still needs to tell clients about the portal, update the deadline page, and keep booking availability current. The website makes those habits easier; it does not replace them.

What this practice deliberately leaves for later is also instructive. It does not add town pages in the first build, because its Leeds and West Yorkshire reach is already clear, and it does not add a full set of team biographies until new photographs are ready. It keeps the GDPR and privacy pages from the base compliance set-up, but it does not commission the full £350 guidance package until it has reviewed its own ICO position with its adviser. Phasing work in this way keeps the launch focussed, avoids paying for pages that would sit half-finished, and leaves a clear second phase if enquiries grow.

Timeline: how long a build usually takes

A typical base build takes three to five weeks from a signed brief to launch, with a portal or larger content set extending that to five to seven weeks. The first week is usually discovery and structure: the provider learns who the firm serves, which services matter most, what content exists, and what systems the portal or booking tool must connect to. The second and third weeks cover design and content, with the firm reviewing pages in batches rather than all at once. The final week covers testing, search optimisation checks, portal and form testing, and launch, followed by a short period of fixes for issues that only appear on real devices.

Delays almost always come from content, not code. Team biographies wait for approval, photographs are not ready, service descriptions need a partner to check technical wording, or a decision about fixed fees versus bespoke pricing is left open. The fastest way to protect a timeline is to nominate one decision-maker inside the firm, agree the fee wording early, and supply photographs and biographies by a fixed date. A provider who promises a full portal build in a few days should be asked what testing, security checks, and client guidance have been compressed to meet that date, because those are the parts that protect clients after launch.

After launch, the work is not finished. Tax deadline pages need annual updates, MTD guidance needs checking when HMRC changes a threshold or date, team pages need updating when staff join or leave, and the Google Business Profile needs attention when opening hours or services change. A modest monthly care arrangement, covering updates, backups, security patches, and small content changes, is usually better value than leaving a site untouched for two years and then paying for a rebuild. Ask what monthly care includes, what counts as a small change, and how quickly security updates are applied.

Mistakes that waste money

The most expensive mistake is choosing a design that looks impressive but hides the service. A homepage dominated by a large image, a vague slogan, and no clear service list forces visitors to hunt for basic information, and many will leave for a competitor whose site answers their question in seconds. A second mistake is publishing fixed prices for complex work without explaining what is included, which creates enquiries that cannot be honoured and clients who feel misled when the final fee differs. A third mistake is adding a portal link that leads to a generic login page with no guidance, which confuses clients and increases support calls rather than reducing them.

Other mistakes are quieter but still costly. Copying a competitor's service pages, with only the firm name changed, harms search visibility and risks misrepresenting the firm's actual services. Using stock photographs of a team that is not yours undermines the trust the site is meant to build. Neglecting the privacy notice, cookie notice, and terms pages leaves a compliance gap that is easy to close at build stage and awkward to explain later. Finally, launching without testing forms, booking, and portal logins on a real phone, on a real network, is a common cause of lost enquiries that nobody notices until weeks later, when a client mentions that a form “did not seem to send”.

To avoid these pitfalls, insist on a pre-launch checklist: every form sends and is received, every booking type books correctly, portal login and upload are tested with a test account, pages load quickly on mobile, titles and descriptions are unique, and the privacy and cookie pages are linked from every form. Ask for a short handover note that explains how to update deadline content, add a team member, and change a fee page, so the firm is not dependent on the provider for every small edit.

Frequently Asked Questions

How much does an accounting firm website cost in the UK in 2026?

Indicatively, from £1,900 for a base build, £2,800 for a worked example with a portal, MTD-ready pages and booking, and £3,600 fully loaded, all excluding VAT. Final pricing depends on page count, portal complexity, content supplied, and integrations.

Are the prices including or excluding VAT?

Prices in this guide are excluding VAT unless stated otherwise. VAT at 20% would take £1,900 to £2,280, £2,800 to £3,360, and £3,600 to £4,320. Always confirm with a provider whether a quote is excluding or including VAT before comparing quotes.

Do I need a client portal, or is email enough?

Email is familiar, but it is not a secure system for sensitive financial documents. A portal gives each client an individual login, a clear upload route, and a record of what has been received. If your firm regularly receives bank statements, payroll data, or tax returns, a portal is a strong investment, even if some clients need help getting started.

What should MTD pages on my website actually say?

They should explain, in plain language, who MTD affects, what digital record-keeping means in practice, which software your firm supports, and how you help clients move from paper or spreadsheets. They should avoid presenting a threshold or start date as permanent, and they should point readers to HMRC for the authoritative rules, with a deadline page you update regularly.

Is a .co.uk domain better than a .com for a UK firm?

For a firm whose clients are mainly in the UK, a .co.uk domain is usually the clearer choice, because it signals a UK business and matches local search expectations. A .com address works well for firms with many international clients. Whichever you choose, register it in the firm's own name and keep renewal details in a monitored inbox.

How long will the website take to build?

A base build typically takes three to five weeks, and a build with a portal and larger content set typically takes five to seven weeks. Content approval is the usual cause of delay, so nominating one decision-maker and supplying photographs and biographies early protects the timeline.

What ongoing costs should I plan for after launch?

Plan for domain renewal, hosting, security updates, backups, and periodic content updates, especially tax deadline and MTD pages. Many firms use a modest monthly care arrangement for updates and small changes, rather than leaving the site untouched until a rebuild is needed.

Methodology note

Ranges in this article are indicative only. They were compiled from published tariffs and project data, checked in October 2026, and organised into a base build plus clearly priced options so readers can compare quotes on a like-for-like basis. They are not a quotation for any specific firm, and they do not include bespoke software development, complex integrations with practice management systems beyond standard portal and booking configuration, or extensive photography. Firms with unusual requirements, such as multi-office structures, multiple languages, or a large archive of guides, should expect a tailored quotation. No client names, reviews, or case results have been invented for this article; the Leeds example is a generic illustration, not a named business.

If your practice needs a clearer site, a secure portal, and content that answers MTD questions before clients phone to ask them, start with the base build and add only the options that solve a real problem in your firm. A site that is clear, secure, and easy to update will outperform a larger site that is vague, hard to navigate, or out of date, however much was spent on it.
