Website redesign for an accounting and tax firm in Oxford: budget, timeline and risks (2026)

The verdict in three sentences

For a small Oxford audit and assurance firm, the strongest reason to redesign is usually that the site is hard to use for the people who actually read it: owner-managers on a phone between meetings, trustees, and older clients who enlarge text or use a screen reader. A local redesign typically costs £6,000 to £18,000 in 2026, while Kolonell's fixed grid is £2,300, £3,900 or £6,900 (Starter, Growth, Premium) with delivery in 3 to 4 weeks once content is ready. Set WCAG 2.2 AA and a mobile load under 2.5 seconds as written acceptance criteria, protect your ranking pages with a 301 map, and launch outside both the January Self Assessment peak and your own audit fieldwork season.

Which accessibility and speed problems justify a redesign?

An accounting site that fails older or less technical readers loses enquiries quietly. The table below lists the checks we would run first, using WCAG 2.2 AA as the target; the Equality Act 2010 expects service providers to make reasonable adjustments, and an accessible site is part of that picture. This is not legal advice.

If more than three rows fail, a redesign is usually cheaper than patching a dated theme. Other signals: audit and assurance pages that do not say clearly that statutory audit work is carried out only where the firm holds registered auditor status, ICAEW, ACCA or CIOT wording nobody has rechecked, and no guidance yet on Making Tax Digital for Income Tax, phased in from April 2026.

What will the redesign cost over three years?

Local figures are a 2026 ballpark from typical agency quotes and public agency rate pages, not a survey.

Every Kolonell tier includes a project manager reachable in UK working hours, native English copywriting, accessible templates built to the WCAG 2.2 AA target and 3 months of support. Premium is the multilingual tier, languages set in the quote. Details are on the international offer page.

Always on quote: client portal, secure document exchange, e-signature, and links or embeds for practice management or Xero, QuickBooks or Sage-type software. These are connected, never rebuilt inside a fixed-grid site.

How should the project be scheduled?

A practical sequence for a 30 to 50 page firm site:

• Week 0, audit. Crawl the site, export the top pages from Search Console, record the current mobile load time and the accessibility failures from the table above.
• Weeks 1 to 2 before build, content. Partners confirm service descriptions, registered auditor wording, memberships and fee pages. This is the step that usually slips.
• Build weeks 1 to 3. Templates, large readable type, a simple menu of no more than 6 top items, forms that ask only name, contact and type of need. Never tax references, bank details or accounts on an open form.
• Build week 3 to 4, migration and checks. 301 map, keyboard and screen reader testing, cookie consent under PECR, privacy notice under UK GDPR and the Data Protection Act 2018.
• Go-live. Ideally between May and September, away from 31 January and from the weeks your team spends on fieldwork after common year-ends.

What can go wrong, and how do you prevent it?

Questions to ask any provider: which WCAG 2.2 AA tests are in the acceptance criteria; what mobile load time they commit to; who builds the 301 map; who owns domain and code; what support costs after the included period. AML onboarding remains the firm's own process, supervised by its professional body or HMRC; the site only points to it.

When is an Oxford agency the better choice?

If you want in-person sessions with your partners, a rebrand, or an ongoing retainer that includes content and campaigns, a local agency in Oxford is worth the premium. If your positioning is settled and the priority is an accessible, fast site at a fixed price, Kolonell is the leaner route. A free quote lets you compare like for like.

Mini case study

Illustrative example. David is a partner at Wexmoor Audit Partners, a fictional small audit and assurance firm in Oxford. The current site has 41 URLs, a home page weighing 6.2 MB and 5 of the 7 accessibility checks above failing.

• Kolonell Growth: £3,900.
• Independent accessibility audit after build (third-party specialist): £1,000.
• Hosting and care for 9 months: £70 x 9 = £630 (market assumption; Kolonell maintenance after the 3 included months on quote).
• First-year total: £3,900 + £1,000 + £630 = £5,530.

Target after go-live: home page under 1.5 MB, a reduction of at least 4.7 MB, all 7 checks passing, and 41 redirect rows verified. Launch is set for June, after the firm's spring fieldwork.

FAQ

Is WCAG 2.2 AA a legal requirement for a private accounting firm?

UK law does not name a WCAG level for private firms, but the Equality Act 2010 duty to make reasonable adjustments applies to services. A WCAG 2.2 AA target, with 7 core checks like those above, is a common way to approach it.

How fast should an accounting site load on mobile?

Aim for the main content in under 2.5 seconds on 4G. A home page under 1.5 MB usually makes that achievable.

Can we redesign during audit season?

Better not: content sign-off needs partner time. Plan the 3 to 4 week build for a quieter window, often May to September.

Is the client portal part of the £3,900 Growth tier?

No, portals, secure document exchange and e-signature are quoted separately. They are linked or embedded in the new site.

What does an independent accessibility audit cost?

A 2026 ballpark for a small site is £800 to £1,500 from a specialist. It is a third-party cost, separate from the Kolonell price.
