30 UK accreditation schemes, with what each one actually requires
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.
Replaces carbonless pads, a filing cabinet and a scanner. Nothing is lost or illegible, and every expiry date comes back to you as work.

913 certificates and forms, filled on site, filed for good.
Gas Safety, EICR, Minor Works, LOLER, F-Gas, FENSA and hundreds more — trade-specific, signed on the device, emailed to the customer as a PDF and tracked to their expiry date.
Nothing is lost, nothing is illegible, and every renewal comes back to you as work.

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.
Accreditation guidance is one part of that step. 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 does accreditation guidance replace?
For most trade businesses, carbonless pads, a filing cabinet and a scanner. Nothing is lost or illegible, and every expiry date comes back to you as work.
Does accreditation guidance work on a phone, and offline?
Yes. The mobile app is offline-first: records created on site are stored on the device and synced automatically, in order, when signal returns. Lofts, plant rooms and rural sites were the design brief.
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.
