About the estimate

How accurate is the estimate?

It uses our published starting prices and a £90 day rate, so it's a good guide. Your exact fixed price comes in the proposal after a free 30-minute call, and it won't go up once agreed.

How is the UK agency figure worked out?

We take the same number of days and apply typical UK agency team rates of £600 to £1,200 a day, from 2026 UK pricing guides.

Is there a monthly fee?

No. The estimate is a one-off build price. An optional Care plan costs £19 a month and covers hosting, updates and fixes.
