A website redesign in the UK costs least for a small business site and climbs steeply once the site is larger or has integrations. A redesign that keeps your platform costs less than a full rebuild. It pays off when the old site is slow, hard to edit or failing to turn visitors into enquiries.

How much does a website redesign cost?
For most UK small and mid-sized businesses, a redesign costs least for a small site and rises sharply for a larger marketing site with integrations. The bracket is wide because “redesign” covers very different jobs.
We cover the wider market in how much a website costs in the UK, and the same pattern holds here. Regional agencies tend to quote the lower figures, London agencies start higher, and freelancers sit below both. Who you ask moves the number more than you would expect.
Here is the rough shape:
| Scope | Relative cost |
|---|---|
| Small brochure site, refreshed | Lowest |
| Larger marketing site with integrations | Considerably higher |
| Enterprise scope with security review | Highest |
These are relative levels, not quotes. Your own number depends on page count, how much copy is being rewritten, and whether the platform changes. The website cost calculator gives a fast estimate if you would rather see a figure before speaking to anyone.
What is the difference between a redesign and a rebuild?
A redesign changes how the site looks and is organised. A rebuild replaces what the site is made of. Most people say “redesign” when they mean either, and the confusion costs them money.
A redesign keeps the platform. You get new layouts, a new visual identity, better page structure and often rewritten copy, all on the CMS you already have. It is cheaper because the foundations stay put.
A rebuild replaces the foundations. That might mean moving from a plugin-heavy WordPress install to a static or headless stack. It costs more because the entire build is done again, and content has to be migrated across.
The honest test is simple. If the site’s problems are visual and structural, redesign. If they are speed, editing pain or maintenance, the platform is the cause, and painting over it will not help. We have written about what a headless build costs and about Astro against WordPress for SEO for anyone weighing that second route.
What drives the price up or down?
Scope is the biggest driver, followed by content, then platform. Design hours matter less than people assume, because on most projects the design and the build are billed together.
Page count and templates
Twenty pages that share four templates are far cheaper than twenty pages that each need their own layout. Ask how many distinct page types you are actually paying for.
Copy and content
This is the line most quotes quietly leave out. If the words are being rewritten, that is real work, and on a bigger site it adds up quickly. If the quote does not mention copy, ask who is writing it.
Platform change
Staying on the same platform is the cheapest path. Moving platform means migrating content, rebuilding templates and testing redirects, and that is where a redesign quietly becomes a rebuild.
Integrations
Booking systems, CRMs, shops and custom calculators each add build and testing time. A calculator is a good example: it looks like a small feature and behaves like a small application.
Who does the work
Hourly rates differ by region and by the size of the agency. Ask for a fixed price with the scope written down, not an estimate of hours.
What did a real redesign deliver?
We can point to one of our own. Hoc Paid Media, a UK PPC agency, had an Elementor site that was slow and no longer matched the quality of their work. We refreshed the brand and rebuilt the site on Astro.
Their mobile PageSpeed score went from 34 to 86 between May and June 2026. Desktop went from 55 to 99. And an inbound white-label lead came through the site within 24 hours of launch.
I should be careful about what that proves. It is one client, and one lead is an anecdote, not a conversion rate. But the speed change is measured, and the cause is easy to trace: the old site was heavy on render-blocking scripts, and the new one is not. The full write-up, with the before and after screenshots, is in the Hoc Paid Media case study.
That job was a rebuild, not a repaint. A visual refresh on the old Elementor stack would have looked better and still loaded slowly.
How do you know a redesign will pay off?
A redesign pays off when it fixes something you can measure. If you cannot name the number you expect to move, you are buying a new coat of paint.
Start with evidence that the current site is costing you:
- Speed. Google’s guidance on Core Web Vitals sets the “good” marks at a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint of 200 milliseconds or less, and a Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of page loads. Run your key pages through PageSpeed Insights. If you fail on mobile, the redesign has a clear job.
- Conversion. Traffic holding steady while enquiries fall points at the site, not the marketing.
- Editing. If a simple change needs a developer, you are paying for that every month.
- Findability. If the pages cannot be read cleanly by search engines and AI assistants, the rest of the site is irrelevant.
Then put a rough value on a fix. If your site generates leads worth a few thousand pounds each, one or two extra enquiries a quarter covers a good part of a mid-range redesign. If it generates nothing today because nobody is finding it, the case is weaker, and money is often better spent on content first.
Sometimes the answer is not to redesign. A site that is fast, easy to edit and converting decently might just need better pages on the same foundations.
It also helps to agree the measure before the work starts. Write down today’s mobile speed score, monthly enquiries and the number of pages that bring in traffic, then check them again once the new site has had time to settle. Without that baseline, every redesign looks like a success to the people who paid for it, and nobody can say whether it was.
How do you protect your rankings during a redesign?
Map every old URL to a new one, redirect permanently, and keep the content that already ranks. Most post-launch ranking drops trace back to skipping one of those.
Google’s own guidance on site moves with URL changes is direct about it. Decide where each old URL should go, use server-side permanent redirects such as 301 or 308, and keep them in place for as long as possible, generally at least a year. It also states that 301 and other permanent redirects do not cause a loss in PageRank.
In practice, that means:
- Export every live URL before you touch anything.
- Keep the titles, headings and copy on pages that already bring in traffic, unless you have a reason to change them.
- Redirect straight to the final page, not through a chain.
- Check the redirects on launch day, not the following month.
None of this is difficult. It is dull, which is why it gets skipped.
