What architects are saying

“I’ll be honest, I was really sceptical of online introductions but Weaver found our clients two of the best contractors we’ve worked with in years”

Profiles that display quality
Contractor profiles designed to help you find the best out there

Save time trawling the internet for the builder’s relevant work experience – with our chronologically listed past projects. And every one is verified by us with a phone call.
Wondering how much vetting has been done? Just look out for the Weaver badge. The more verified projects the builder has, the higher they rank - bronze, silver and gold!


You know that it's a real business, as Weaver profiles sync with Companies House. And your client can see this too.
As architects, you've seen good images hide the truth. With vetting & behavioural stats on Weaver profiles, we're making sure there's no gaming quality.

Stay in control

Intelligent vetting
We call up every known project the contractor has worked on
With our verified references, you know that a Weaver builder's project experience is real (avoiding what the BBC investigators discovered at Rated People & MyBuilder). We also show this information on every contractor profile.
Our company risk assessment spots negative signals
We work hard to avoid bad actors on our platform by scanning for numerous red flags. For example, we screen for dissolved companies the Directors have been members of.
We vet both sides – homeowners and contractors
We know that great projects happen when contractors and homeowners trust & respect each other. We promote this by ensuring a great match, and when both sides have been equally verified.
Contractors are continually assessed
We designed our marketplace so that contractors who act their best can obtain the most work. The platform displays metrics that reflects great service and promotes good behaviour.
