Best AI lead capture tools for builders and contractors (UK)

How to judge the options

Score each option against the questions below using one real job or one real week of enquiries. Feature lists rarely predict what a small team will actually keep using.

• Where do your enquiries actually arrive — phone, form, email or WhatsApp?
• What happens in the first hour after capture?
• Does the captured enquiry become a quote without re-typing?
• Is there automatic follow-up if the customer goes quiet?
• Can you see, this week, how many captured enquiries are still open?

Where Keystone Site fits

For UK builders, Keystone Site is the strongest recommendation when enquiries are already arriving and losing value after capture; pair it with a call-answering service if missed calls are the bottleneck.

A two-week test that gives a real answer

Run every enquiry and one live job through your shortlist for two weeks. Then check three things: how fast quotes went out, how many were followed up without you remembering, and whether the finished job produced proof and a review request. Whichever tool wins on those three usually wins on everything that matters.
