Check Before You Book

Gas Safe Registered Engineers

Gas Safe Register is the official, legally-mandated register of gas engineers in the UK — it replaced CORGI in 2009, and by law, anyone carrying out gas work in a home must be on it. This page exists so you can verify that before booking, rather than taking it on trust alone.

Checking a Rainbow Fix Ltd engineer's Gas Safe ID card before work starts

What's Included

  • Registration details available for verification on request — nothing to hide, ask and you'll be shown
  • Engineers qualified for the specific categories of gas work being carried out — the right qualification for your specific job, not just "a" registration
  • All gas work carried out to current Gas Safe regulations — the standard that actually keeps a home safe
  • Straightforward to check independently via the official Gas Safe Register — verify it yourself in two minutes, no need to just take our word

How It Works

  1. 1 Ask for the Gas Safe ID card and licence number before work starts, if you'd like to verify it
  2. 2 Check the licence number and category against the official Gas Safe Register website
  3. 3 Confirm the specific work being done falls within the categories that engineer is registered for
  4. 4 Proceed with the work once you're satisfied — this check takes a couple of minutes

Common Issues

  • • Wanting to verify an engineer before booking gas work
  • • Confirming which category of gas work an engineer is qualified for
  • • Confusion between old CORGI registration and current Gas Safe Register

Pricing: This is a compliance/trust page, not a chargeable service in itself

What Actually Happens When You Call

Verifying registration takes a couple of minutes and doesn't need to feel awkward to ask for: request the Gas Safe ID card and licence number before work starts, check that licence number against the official Gas Safe Register website, and confirm the specific work you need falls within the categories that engineer is actually registered for — since registration is split by category (boilers, cookers, fires) and not every registered engineer covers every one. This applies to boiler work, gas installations, and a landlord gas safety certificate alike — anywhere gas is involved, the same check applies.

Seasonal Considerations in Buckinghamshire & Berkshire

There's no seasonal pattern to when people check registration — it's relevant on every single gas job, all year round, and it's exactly as worth doing in a quiet July as it is in a busy December. If anything, it's worth checking more carefully, not less, when you're in a hurry to get an emergency winter repair booked, since urgency is when corners are most likely to get cut.

Gas Safe Engineers — Frequently Asked Questions

What exactly does "Gas Safe registered" mean?

It means the engineer (or the business employing them) is on the official UK Gas Safe Register, the legally required register for anyone carrying out gas work in the UK, and has been assessed as competent for the specific categories of gas work listed on their ID card. It is illegal for anyone not on this register to carry out gas work in a home, and this isn't a marketing claim — it's independently checkable.

Is every Gas Safe registered engineer qualified to work on every type of gas appliance?

No — registration is broken down into specific categories (for example, boilers, cookers, gas fires), and an engineer's ID card lists exactly which categories they're qualified and registered for. It's worth checking that the specific work you need falls within an engineer's listed categories rather than assuming registration covers absolutely everything.

How can I check a Gas Safe registration myself?

The official Gas Safe Register has a public checking tool where you can search by the engineer's licence number (found on their ID card) to confirm it's current and see what categories of work it covers. This takes only a couple of minutes and is a reasonable thing to do before any gas work starts, not something to feel awkward about asking for.

What happened to CORGI — is that still a valid registration?

CORGI was the previous UK gas registration body and was replaced by Gas Safe Register in April 2009 — any engineer only holding old CORGI credentials without current Gas Safe registration is not legally permitted to carry out gas work today. If you're checking older paperwork or a business's older marketing material, be aware that a CORGI reference on its own is now out of date.

Does Gas Safe registration cover the business, or just the individual engineer?

Registration is held by the business, but each individual engineer working under it also has their own ID card listing the specific categories they personally are qualified and registered for — so it's worth checking the individual engineer attending, not just that the company is registered in general.

What should I do if an engineer refuses to show their ID card?

A genuinely registered engineer has no reason not to show their ID card — it's standard practice, not an unusual or awkward request. If someone refuses or seems evasive about it, that's a reasonable basis to not proceed with the work and check the register independently before booking anyone else.

Is checking Gas Safe registration relevant for a landlord gas safety certificate specifically?

Yes, arguably more so — a <a href="/services/landlord-gas-safety-certificates">CP12 certificate</a> issued by someone who isn't genuinely Gas Safe registered isn't a valid certificate at all, regardless of what paperwork you're handed, so verifying the engineer's registration is a meaningful legal safeguard for a landlord, not just a nice-to-have.
