Two questions, and every number behind the answer was read off a real UK price on a real page. Nothing here is a formula with invented multipliers in it.
Website cost calculator · UK · 2026
To build
£1,200 to £4,000
Over three years
£1,431 to £4,722
Plus hosting and a domain at £77 to £241 a year, which is £231 to £722 over 3 years. Keeping the platform patched is on top and has no list price.
Where this band comes from: Both endpoints are anchors from quoted ranges on page one, July 2026.
Most cost calculators ask you for a page count and a feature list, then multiply. The multipliers are invented, which is why two calculators give wildly different answers for the same brief.
This one places you in one of four bands that were read off page one of UK search in July 2026, then does the only arithmetic that holds up: what that band costs once three years of running it are counted. Hosting and a domain come to £77 to £241 a year, which is the part almost nobody puts in the quote.
A template and your own weekends. Wix, Squarespace, GoDaddy.
Wix Light at £9 a month up to Wix Business at £25, read off wix.com and squarespace.com from a UK connection, July 2026. Standard prices, not the 50% promotion running at the time.
Code you own, written with Claude Code or similar. The subscription is the cheap part. Your time is not.
Claude Pro at £15 a month on annual billing up to Max from £90, read off claude.com/pricing from a UK connection, July 2026, VAT included. The page names a Max 20x tier but publishes no price for it, so £90 is the top of the sourced range.
The same template, configured for you. Usually with a monthly tie-in.
Two agencies ranking on page one: Harris Digital at £299, digitalroyalty at £499.
A layout designed around how you sell, your copy, one clear path to enquiry.
Both endpoints are anchors from quoted ranges on page one, July 2026.
Bespoke design and code, built to be owned, extended and handed over.
Top of the highest quoted range on page one, July 2026.
The longer version, including what moves you between bands and what nobody quotes up front, is in what a website costs in the UK. What it costs once it is live is in what a website costs to run.
