Most businesses price a website by counting pages. The published prices say that is the wrong question.
This free calculator quotes the corridor of real, published UK web design prices for the kind of build you choose. Every number on this page comes from prices UK agencies, studios and freelancers publish on their own websites: the 28 one-off and 5 monthly web design prices in Whito’s June 2026 price file, and the 21-provider retainer read from September 2026. Nothing is estimated and nothing is gated. No email required.

What the file shows
In Whito’s June 2026 price file, an 11-page site cost £299 while a one-page site cost £450, and a 22-page build cost less than a five-page one: across the 15 one-off prices that state a page count, page count explains almost none of the published price.
We call this the pages-don’t-price rule: published UK web design prices move with the build approach, the design level and whether the site sells, not with the page count. That is why this calculator asks what kind of build you want before it asks how many pages.
The published corridors this calculator quotes
Grouped by what the provider calls the package. Prices are as published; several are from-prices and some exclude VAT.
| Build | Published corridor | Median | Prices |
|---|---|---|---|
| Packaged or template build | £299 to £995 | £472.50 | 18 |
| Customised design | £540 to £1,500 | £800 | 5 |
| Fully bespoke, from scratch | £2,000 to £4,500 | £2,500 | 3 |
| Online shop (any build) | £549 to £3,000 | £1,399 | 3 |
| Monthly website plan | £19 to £145 a month | 5 | |
| Website care plan (support) | £50 to £177.50 a month | 18 lists | |
| Development retainer (support) | £450 to £6,500 a month | 4 lists |
The median one-off web design price across all 28 published prices is £520. The bespoke corridor’s top entry is the midpoint of one agency’s published £3,000 to £6,000 range.
How to read the result
The corridor is not a quote. It is the range of what comparable work is published at, so you can see where a quote sits before you sign. A quote above the corridor is not automatically wrong; it should come with a reason you can point at. A quote below every published price usually means something you need is not included.
Three things the corridors hide, stated plainly: many prices are from-prices, so the real invoice lands higher; on care plans, 13 of the 21 providers we read do not state VAT beside the plan price; and a monthly plan can cost more over its term than a one-off build, one published 24-month plan totals about £3,480.

FAQs
How much does a website cost in the UK in 2026?
Across the 28 one-off web design prices UK providers published in Whito’s June 2026 file, the median is £520. Packaged builds ran £299 to £995, customised design £540 to £1,500, and fully bespoke builds £2,000 to £4,500 published, with one published range reaching £6,000.
Does the number of pages change the price?
Far less than most buyers assume. In the same file an 11-page site cost £299 while a one-page site cost £450. The pages-don’t-price rule: build approach and design level move the price; page count mostly does not.
What should ongoing website support cost?
Published UK website care plans run £50 to £177.50 a month across 18 lists read in September 2026; development retainers run £450 to £6,500 a month across the 4 published lists. Seven one-hour care plans ran £49 to £170, median £95.
Where do these numbers come from?
From prices published openly by UK agencies, studios and freelancers, collected into Whito’s June 2026 price file (128 prices, 47 providers) and the September 2026 retainer read (21 providers). Nothing in this tool is a survey answer or an estimate.
