Is it worth it?
At £700, the question isn’t the fee — it’s whether it wins you work. For heating engineers it usually does, because it’s the first thing a cautious customer or a commercial buyer checks. Most trades hold accreditations and then hide the logos in the footer. If you’ve paid for it, it belongs where customers actually look.
Tracking it
Accreditations lapse quietly. The renewal date lands in a busy month, nobody spots it, and you find out when a customer asks for the certificate. Gaffer keeps your accreditations, evidence and renewal dates in one place and reminds you before they expire.
