Gas Safe Register
The legally required register for businesses doing gas work in Great Britain, Northern Ireland, the Isle of Man and Guernsey
Market position
Gas Safe Register is the register of gas businesses approved by the Health and Safety Executive (HSE) under the Gas Safety (Installation and Use) Regulations 1998, and it replaced CORGI on 1 April 2009. HSE says a gas engineering business must be on the register to legally undertake gas work within the scope of the Regulations. HSE names Capita Gas Registration and Ancillary Services Ltd, part of Capita plc, as the operator.
United Kingdom-specific note
Regulation 3(3) says no employer may let employees do gas work in scope, and no self-employed person may do it, unless they belong to a class approved by HSE, which is Gas Safe Register. Regulation 3(1) also requires everyone doing gas work to be competent. HSE says the register covers Great Britain, Northern Ireland, the Isle of Man and Guernsey. Registration is renewed each year online or by phone and mail, and HSE prosecutes unregistered gas fitters.

Why this matters for United Kingdom trades
Gas Safe Register is the register approved by HSE: a business must be on it to legally do gas work within the scope of the Gas Safety (Installation and Use) Regulations 1998, and HSE prosecutes unregistered gas fitters. For electrical work in dwellings, NICEIC (Certsure) is one of several authorised competent person schemes, alongside BESCA, Blue Flame Certification, NAPIT and OFTEC, that let installers self-certify instead of getting building regulations approval, and OFTEC is one of six schemes authorised for oil appliances. The payroll tools listed here are on HMRC’s list of recognised payroll software, while CIS returns may need an add-on or a separate product; insurers such as Hiscox and AXA note that employers’ liability insurance is a legal requirement once you employ staff.
UK trades vendor selection is shaped by the Gas Safe Register for gas work, competent person schemes such as NICEIC and OFTEC that let installers self-certify building work, payroll duties (HMRC RTI reporting, workplace pension auto enrolment and, in construction, CIS returns), VAT, and lead services such as Checkatrade, MyBuilder and TrustATrader.
