How much does an AI chatbot cost in the UK?
Most quotes fall into two shapes. Agencies charge a one-off build fee, typically £3,000 to £15,000, then bill separately for hosting, changes and support. Or you pay a monthly platform fee for a self-serve tool you configure and maintain yourself, usually £30 to £300 a month, which is cheap until you need it to do something the template does not cover.
Ostfro works the second way with the first way’s quality: a flat monthly plan from £299, no upfront build fee. Building, hosting, monitoring, fixes and monthly improvements all sit inside it. If the chatbot needs changing in month seven because your pricing changed, that is not a new invoice.
The honest variable is scope. A bot answering twenty repeat questions from your existing documents is quick. One that checks live stock, takes payment and writes to your CRM is a bigger build, but it is the same monthly plan, and the scope is written down before anything starts.
