Step 04 of the job: on site
The engineer taps “On my way” and the customer gets a text with an arrival window. On site: clock in, photos, the certificate for the job — EICR, Gas Safety, whatever the trade needs — signed on the device. No signal? It syncs later.
Compliance & Certificates is where accreditation guidance sits, and that is the step it shows up in most. The rest of the job — quoting, scheduling, certificates, invoicing and payment — runs in the same system, on the same record. See the whole job →

What is accreditation guidance for?
Getting CHAS, Constructionline, NICEIC or ISO 9001 is mostly a matter of knowing what evidence they want. Gaffer holds 30 UK schemes with their real requirements, the evidence needed for each, typical cost and renewal period — and tracks your application through a checklist to submission.

Are the certificates acceptable to landlords and inspectors?
They carry the fields the schemes expect, your registration numbers, the date, the engineer and a signature, and they go out as a branded PDF. Whether a scheme requires its own branded form is worth checking for your trade before you switch.
What happens when a certificate is about to expire?
It surfaces before it lapses, not after. You get the alert, and the customer can get a text with a booking link — which is how last year’s compliance turns into this year’s work.
Which plan is it on?
Accreditation guidance sits on the Enterprise plan, alongside multi-site support, white-label and a dedicated account manager. Everything else in Gaffer is on every paid plan; talk to us and we will tell you honestly whether you need Enterprise or not.
