What our clients say
“We needed a single new build tested at short notice. TargetCO2 gave us clear prep advice, came out when they said they would and the certificate was with Building Control the next day. We’ll be using them on all our future plots.”– M. Harris, Builder, near Exeter
“As a self-builder I wasn’t sure what to expect. Everything was explained in plain English and we passed first time. The whole process was much easier than I’d anticipated.”– Self-build client, Truro
“Great communication, flexible on dates and reports that our local Building Control are happy with. Being able to point clients to a reliable tester makes our lives much easier.”– T. Davies, Architect, Plymouth
