A UK website redesign can cost thousands or tens of thousands of pounds depending on the project. A five-page marketing refresh is different from a multilingual ecommerce rebuild with CRM, ERP and bespoke checkout integrations. Before asking agencies for quotes, make sure they are pricing the same outcome.
UK Website Redesign Costs: Illustrative Budget Ranges
The bands below are illustrative planning scenarios, not surveyed market averages or Working Weekends prices. They show how scope can change a budget; request itemised quotes for your actual requirements. VAT, subscriptions and support may be additional.
| Indicative project type | Illustrative budget band | Check carefully |
|---|---|---|
| Basic marketing website, 5–10 pages | £5,000–£15,000 | Does the scope include content and redirects? |
| Mid-sized corporate website | £15,000–£40,000 | Are research, templates, analytics and training included? |
| Custom ecommerce or web application | £40,000–£120,000+ | What functionality makes the work bespoke? |
Project cost depends on content volume, design system, accessibility needs, integrations, technical dependencies and sign-off complexity. A narrowly scoped refresh may cost less, while enterprise replatforming may cost more. Check whether VAT, subscriptions and ongoing support are additional.
Five Questions to Define Your Website Redesign Scope
- What is failing today? Diagnose slow mobile journeys, confusing offers, weak SEO, poor form completion or maintenance problems.
- What actually needs changing? Agree page templates, integrations, languages, forms and accessibility requirements.
- What must not break? Preserve valuable organic URLs, customer logins, existing redirects, analytics and operational processes.
- Who creates and signs off content? Plan expert review, photography, case-study permission and legal copy.
- How will results be measured? Agree a baseline for qualified enquiries or purchases, not merely a new visual style.
Website Redesign Features That Increase Project Cost
| Component | Smaller scope | More complex scope |
|---|---|---|
| Design | Adapt approved components | Custom responsive design system |
| Content | Refine existing pages | Expert interviews, extensive writing and migration |
| Functionality | Contact forms and standard integrations | Accounts, pricing rules and API workflows |
| SEO | Preserve canonical URLs and titles | Large redirect mapping and international search |
| QA | Standard browser and device checks | Accessibility and critical workflow regression testing |
When a Website Audit Is Better Than a Full Rebuild
A complete rebuild is not always the right purchase. Inspect your highest-value pages, actual buyer tasks, conversion friction and platform stability first. If the platform works and prospects simply cannot find a clear service description or form, a focused conversion sprint can be more defensible. If the backend prevents essential functions or changes repeatedly break integrations, deeper reconstruction may be justified.
Google's Web Vitals guidance covers LCP, INP and CLS as technical user-experience measures. Better scores do not guarantee higher revenue. Pair them with direct task-completion tests on mobile, including forms, bookings and checkout.
How to Protect SEO During a Website Redesign
Record important landing pages, titles, canonical links, navigation paths and redirect rules before changing templates. If URLs move, test permanent redirects. Make essential content crawlable and check the new site in mobile layouts before launch. The Google SEO Starter Guide provides the technical foundation.
How to Estimate Website Redesign ROI from Enquiries
Illustrative calculation: with 2,000 relevant monthly visits and a 2% enquiry conversion rate, a site generates 40 enquiries. A 2.5% rate on unchanged traffic would produce 50—ten more. That arithmetic is not a forecast. Qualification, sales close rates, attribution and seasonal patterns all affect the commercial result. Agree on how a qualified enquiry will be tracked before commissioning design work.
How to Compare Website Redesign Quotes Fairly
Suppose two purely hypothetical quotes are £8,000 and £11,000. The smaller one might exclude copy, redirects and device testing, while the larger one includes them. Neither quote is automatically better. Ask both suppliers to price the same page and template list, identify inclusions, and define a defects period and measurable acceptance criteria.
A good proposal should include a page inventory, responsibilities, implementation timeline, revision policy, mobile QA, integrations, redirect owner, analytics validation, accessibility scope, launch plan and maintenance terms.
