A Gas Safe Register engineer

The Gas Safe Register is nationally recognised as the official certification for heating and boiler engineers who work on residential or commercial boiler and heating systems in the UK. You should always request and ensure that anyone working on your boiler is appropriately trained to keep your household safe.

Gas Safe Register - what is it?

Gas Safe Register logo

The Gas Safe Register is a certification for UK boiler installation, maintenance and heating technicians that ensures gas repairs, checks and inspections for your home are carried out safely by people who are appropriately trained.

It became the officially recognised certification in 2009, superseding the CORGI scheme which had been in place since the early 90s.

Gas Safe registered technicians and engineers have an ID which details what types of repairs they are licensed to carry out safely and additionally they are also searchable in the online version of the register.

Registered engineers need to show that they hold one of the accredited qualifications for their trade. These qualifications include ACS, NVQ, SVQ and Scotland’s QCF.

Find your nearest gas safe engineer

The Gas Safe Register website lets you search the register by engineer and business name but more importantly also by location.

  1. Enter your Post Code in the Register search
  2. Click on the yellow (+) button to “Choose Appliance”
  3. Select what type of gas your household uses. Natural/Main Gas will be the more common option for regular homes with LPG/Cylinder being more widespread for commercial and rural customers.
  4. Choose the relevant appliances you need them to look at or fix and the Register search will narrow down the available engineers to those who are qualified to work on the appliances you selected. You can tick more than one appliance in a single search.

Each entry in the search results contains a wealth of information on both the registered companies and the individual engineers that work for them. For starters, you will get the name, physical address and relevant contact details for each business. Being able to put an address and phone number to the business that will be servicing your boiler or central heating certainly brings some peace of mind with it.

Once more the yellow (+) icon is very useful since it shows the categories of repairs and inspections the company is certified in. Each category has its (+) symbol which discloses further details within each appliance or category.

The same level detail is extended to each engineer shown once you click the “View our engineers” dark green button. This means you can see an exhaustive list of service repairs they are registered for.

What do Gas Safe Registered engineers do?Most technicians will be able to install a boiler replacement, hot water heaters and central heating systems. They will also be able to repair valves, thermostat malfunctions, flue issues and ensure your carbon monoxide detector will pick up any leak.

How to check if a gas safe engineer is real or not

All gas safe fitters and technicians will have a valid Gas Safe ID with them at all times. You are well within your rights to ask them to show you their card and it is something they are expected to produce.

  1. Name
  2. Company name
  3. Gas Safe registration and license numbers
  4. The date the card was issued and its expiration
  5. The card will also have the Gas Safe Register phone number in case you need to check the validity of the card on the spot.
  6. Security hologram and QR code

On the back, you will find details relating to the kind of work they can do:

  1. Domestic or non-domestic skills
  2. The type of appliance or service they have certification for
  3. Gas Fuel type
  4. Expiration dates for their qualifications

If a friend or family or friend recommends a gas fitter for your plumbing and heating needs, you should insist that they be Gas Safe registered no matter how highly recommended they are or how good their deal is. About 250 000 illegal gas repairs happen in the UK every year and about 50 000 of those led appliances, boilers and heating systems needing to be turned off immediately to avoid harm and further damage.

How to become certified

How to become a gas safe engineer

Any gas or heating engineer wishing to become part of the Gas Safe Register needs to show that they are qualified and competent. To do so applicants must have successfully completed one of the following training programmes that are part of the IGEM/IG/1 accreditation:

  • NVQ or SVQ (National or Scottish Vocational Qualification) is an entry-level training programme for those who have no experience as a plumber or gas fitter. There are three Gas Service NVQs allocated by City and Guilds and they cover: installation and maintenance of natural gas, emergency service and appliance pathways.
  • ACS (Accredited Certification Scheme) is a higher level qualification for experienced gas engineers who want add endorsements to their Gas Safe Register profile to allow them to inspect and work on a wider range of appliances and heating systems.
  • QCF (Qualification Credit Framework) is overseen by the SQA (Scottish Qualifications Authority) and can be equivalent to ACS in the following areas: home energy installation or upkeep of residential appliances and meters. This applies to natural gas and LPG (liquefied petroleum gas).

Gas Safe Register accreditations are reviewed every five years, even if you had been in the index previously. If your qualifications or endorsements are out of date, applicants will be under obligation to retrain in the areas they want to specialise in. Whether applicants are brand-new or returning to the industry they will have to pass a trimester-long documented probationary period and inspection.

Gas safe register login

The Gas Safe Register website does not have login for residential customers looking to find qualified technicians. However, it does have a portal for registered fitters called the “Engineer Area.”

Gas safe portal login page

Registered members can sign in using their valid User ID or Licence and Registration numbers. This online account lets them view safety alerts, updates and bulletins as well as manage their gas safe profile and local inspector contacts.

From a consumer perspective, we think that engineers having access to this kind of industry-wide support means better service for the communities they serve.
