How to Become Gas Safe Registered

Registration depends on holding a recognised gas qualification for each type of work you do. Most engineers qualify through an apprenticeship or a recognised training route, then pass assessments under the Nationally Accredited Certification Scheme (ACS).

ACS assessments cover specific work categories, such as domestic boilers, cookers or gas fires. They must be renewed every five years.

Registration is held by a business, which then adds each qualified engineer. A sole trader registers as a business with one engineer.

There is a registration fee, renewed every year. Gas Safe Register can inspect a sample of each engineer's work.

Each registered engineer receives an ID card showing their licence number and the categories of work they are qualified for. Customers are told to ask to see it.

Homeowners are increasingly told how to check this. Our page How to Check a Tradesperson’s Registration explains it from their side.

When you install a new boiler or other notifiable appliance, you must notify it through Gas Safe Register. The customer then receives a Building Regulations compliance certificate.

Missing notifications cause problems for customers years later, when they sell.

Gas Safe registration is one of the accreditations you can add to your Propvio profile. Propvio checks it before awarding your Verified badge.
