Website Redesign Cost UK: What a Rebuild Actually Costs in 2026

A UK website redesign typically costs between £10,000 and £80,000, with most B2B projects landing in the £15,000 to £60,000 range. The figure moves on a handful of drivers: the number of unique page templates, how much is bespoke versus built on a proven framework, the integrations involved, and how much content has to migrate. A pure platform migration with no redesign sits lower, in the region of £8,000 to £18,000. This guide breaks down where the money goes, how a redesign differs from a new build, and how to tell whether you actually need one in 2026.

Redesign, new build or migration: which one are you buying?

These three words get used interchangeably, but they describe very different scopes and price tags. Getting the label right is the fastest way to sanity check a quote.

• A redesign reworks an existing site's design, structure and user experience, often keeping the platform you are already on. The UK market range runs roughly £10,000 to £150,000 depending on complexity, page count and integrations.
• A new build is a ground-up rebuild, frequently paired with a platform change. An engineering-led HubSpot build typically runs £15,000 to £60,000 and above, with enterprise scopes climbing past that.
• A migration only moves your existing content and design onto a new platform without redesigning anything. Partner-led HubSpot migrations commonly land at £8,000 to £18,000, and most mid-sized B2B sites of 50 to 200 pages complete in four to eight weeks.

One thing to watch: HubSpot's own low-cost migration service is a lift-and-shift only. It excludes design, custom development and content strategy, so it is not a redesign. If your existing site looks tired, a straight migration will faithfully reproduce a tired site on a better platform.

What a UK website redesign actually costs in 2026

Here are the indicative ranges we see across the UK market. All figures are ex VAT and should be read as approximate, since platform fees in particular get revised.

• Smaller redesigns: from around £10,000.
• Standard HubSpot CMS build: £15,000 to £30,000, usually 12 to 14 weeks.
• Complex build: £30,000 to £60,000, around 14 to 18 weeks.
• Enterprise build: £60,000 and up.
• Copywriting (add-on): from roughly £1,500 for strategic guidance to around £14,000 for full agency copywriting.

Remember that the build is separate from the platform subscription. HubSpot Content Hub sits at around £500 per month on Professional, with Enterprise nearer £1,500 per month, billed on top of the one-off project cost. Both figures are ex VAT. Bundling Content Hub with other Hubs and paying annually usually trims the platform spend, and buying through a certified Solutions Partner can waive the mandatory onboarding fee.

The cost drivers that actually move the number

Two agencies can quote wildly different figures for what sounds like the same site. The gap almost always comes down to these drivers.

Number of unique templates and bespoke versus framework

Every unique page template is design plus build plus testing. A site that needs ten genuinely different layouts costs far more than one that reuses three well-built templates. Building on a proven framework rather than designing everything from scratch is the single biggest lever on price, and it is usually the better engineering decision too.

Custom modules, integrations and migration volume

Custom-coded modules and serverless functions, CRM and third-party system integrations, custom object mapping, and the sheer volume of content to migrate all add cost. So do multilingual requirements, memberships or a customer portal, and strict accessibility and performance targets. HubSpot builds tend to run a little higher than equivalent WordPress or Webflow projects because HubL templating needs specialist developers and the build includes proper CRM configuration. That premium buys you a platform where hosting, security and CMS maintenance are folded into one fee.

Signs you need a redesign, not a patch

A redesign is a serious spend, so it should be triggered by evidence, not boredom with the look. The clearest signals in 2026 are performance and search related.

• Slow load times. Google's longstanding "good" Largest Contentful Paint target is 2.5 seconds, and industry reporting around the March 2026 update suggests Google is tightening how strictly it treats LCP. If your pages routinely load slower than 2.5 seconds, you are already on the wrong side of the line.
• Failing Core Web Vitals. Only around a third of sites pass all three Core Web Vitals. Interaction to Next Paint is the hardest to satisfy, with roughly 43 per cent of sites failing the 200ms threshold. INP is now the most commonly failed metric.
• The problem is structural. Fixing INP usually means changing JavaScript architecture, not applying quick wins. When the fix is architectural, you are effectively rebuilding anyway, which is the moment a redesign becomes the rational choice.
• Site-wide drag. Google now aggregates Core Web Vitals across the whole domain, with mobile carrying more weight. A handful of strong pages will not rescue a site where a quarter of URLs perform poorly.

The commercial case is real. In one widely cited example, Rakuten 24 reported that improving LCP scores drove a 53 per cent lift in revenue per visitor and a 33 per cent rise in conversion rate. That is a single-company result rather than a guarantee, but it shows the direction of travel: performance is now a revenue lever, not a vanity metric. An engineering-led HubSpot website build bakes these performance targets in from the start, rather than bolting them on afterwards.

The migration cost angle: why "redesign" often means "move platform"

Frequently the real trigger behind a redesign is the running cost of the platform you are on. WordPress is the classic case. Basic maintenance runs around £75 to £150 per month, business-level support climbs to £200 to £350, and that sits on top of separate managed hosting and premium plugin licences that can reach hundreds of pounds a year.

Security is the sharper issue. Plugins account for 96 to 97 per cent of WordPress vulnerabilities. One week in January 2026 saw 333 new vulnerabilities disclosed across plugins and themes, and patches that spring across widely used plugins touched tens of millions of installations combined. Each of those is a maintenance event you have to notice, assess and act on.

This is where a total cost of ownership view changes the maths. A hosted platform like HubSpot Content Hub folds hosting, security and CMS maintenance into the platform fee, replacing WordPress's fragmented and accumulating running costs with one predictable line. The redesign is the obvious moment to make that move, because you are touching the templates anyway. Our wider HubSpot development work covers the custom modules and integrations that make such a move worthwhile rather than a like-for-like copy.

It also reframes how you think about spend after launch. On a self-managed stack, the redesign is the start of a long maintenance bill that grows quietly as plugins age. On a hosted platform, the recurring cost is largely the predictable platform fee plus a modest support retainer, often from around £600 per month, for content updates and monitoring. Modelling those running costs alongside the build is the difference between a one-off quote and a genuine three-year figure, and it usually flatters the hosted option once security and hosting are accounted for. Our HubSpot website redesign and migration work is scoped to keep that ongoing number flat and predictable.

How to budget with confidence

Start by classifying the project honestly: redesign, new build or migration. Then list your unique templates, your must-have integrations and the volume of content moving across, because those three things explain most of the variance in any quote. Insist on a discovery phase that sets goals and success metrics up front, so the build is measured against outcomes rather than opinions. If you want a scoped figure for your own site, you can request a quote and we will map the drivers above to a fixed plan, delivered on time or you get 20 per cent back.

Frequently asked questions

How much does a website redesign cost in the UK in 2026?

Most UK B2B website redesigns cost between £15,000 and £60,000, with smaller projects starting from around £10,000 and enterprise scopes running past £60,000. The number is driven mainly by how many unique page templates you need, how much is bespoke versus built on a proven framework, the integrations involved, and how much content has to migrate. All figures are ex VAT and indicative, since scope varies site to site.

What is the difference between a website redesign and a new build?

A redesign reworks the design, structure and user experience of an existing site, often keeping the same platform, and runs roughly £10,000 to £150,000 in the UK. A new build is a ground-up rebuild, frequently with a platform change, and an engineering-led HubSpot build typically costs £15,000 to £60,000 and above. A new build costs more because nothing is reused, but it gives you a cleaner foundation when the existing site is structurally weak.

Is migrating to a new platform cheaper than a full redesign?

Yes. A migration that moves your existing content and design to a new platform without redesigning anything typically costs £8,000 to £18,000 in the UK, and most mid-sized B2B sites of 50 to 200 pages complete in four to eight weeks. The trade-off is that a straight migration faithfully reproduces your current site, including any tired design or weak structure, so it suits sites that are already in good shape.

What are the signs I need a website redesign rather than a quick fix?

The clearest 2026 signals are performance and search related: load times slower than Google's 2.5 second "good" LCP target, failing Core Web Vitals (only about a third of sites pass all three), and a high Interaction to Next Paint, which around 43 per cent of sites fail at the 200ms threshold. When fixing those problems means changing JavaScript architecture rather than applying quick wins, you are effectively rebuilding anyway, which is the point a redesign becomes the rational choice.

Does the website build cost include the HubSpot platform fee?

No. The one-off build cost and the recurring platform subscription are separate. HubSpot Content Hub sits at roughly £400 per month on Professional and nearer £1,500 per month on Enterprise, billed on top of the project. Bundling Content Hub with other Hubs and paying annually usually reduces the platform spend. A hosted platform does fold hosting, security and CMS maintenance into that fee, which can lower your total cost of ownership compared with a self-managed platform.
