If you let a property in Glasgow or Lanarkshire with any gas appliance in it, you need a gas safety check every twelve months by a Gas Safe registered engineer. That part is UK-wide law. What most online guides miss is that Scotland has its own layer of rules on top — landlord registration, the Repairing Standard, the Tolerable Standard, carbon monoxide alarm requirements and a tribunal that can order rent reductions — and English guides get them wrong or leave them out.
This guide covers both, in plain English, for landlords and letting agents in Scotland.
What the law requires (UK-wide)
The Gas Safety (Installation and Use) Regulations 1998 apply to every landlord in Scotland, England and Wales. In summary you must:
- Have every gas appliance, flue and the pipework you provide checked for safety every 12 months by a Gas Safe registered engineer
- Give a copy of the record to existing tenants within 28 days of the check
- Give new tenants a copy before they move in
- Keep records for at least two years
- Make sure appliances, flues and pipework are maintained in a safe condition (so repairs, not just checks)
The record is what everyone calls a CP12 or Landlord Gas Safety Record. It lists each appliance, the checks carried out, any defects found and what was done about them.
Appliances the tenant owns (their own cooker, for example) don't need to be on your certificate, but the pipework to them does, and most engineers will visually check the tenant's appliance anyway.
The 12-month rule and the two-month early window
Since 2018 the rules work like a car MOT. If you have the check carried out in the two months before the current certificate's expiry date, the new certificate runs from the old expiry date, not from the date of the check. So you don't lose any days by being early — and you have a two-month window to get access, which matters when a tenant is hard to pin down.
If you're late, there is no grace period. A property with an expired gas safety record is a property being let unlawfully.
What Scotland adds on top
Landlord registration
Every private landlord in Scotland must be on the Scottish Landlord Register with the local council (Glasgow City, North Lanarkshire or South Lanarkshire for our area). Registration has a "fit and proper person" test, and a history of ignoring safety obligations can count against you. Letting without registering is an offence.
The Repairing Standard
Under the Housing (Scotland) Act 2006, every privately rented home must meet the Repairing Standard at the start of the tenancy and throughout it. Among other things it requires that installations for the supply of gas and for space and water heating are in a reasonable state of repair and in proper working order. mygov.scot puts it plainly: gas supply and equipment must be "safely installed and maintained by a Gas Safe registered engineer" and "checked annually by a registered engineer."
The Repairing Standard is enforced by the First-tier Tribunal for Scotland (Housing and Property Chamber). A tenant can apply directly. If the tribunal finds against you it can issue a Repairing Standard Enforcement Order, and failure to comply can lead to a Rent Relief Order reducing the rent by up to 90% until the work is done. Councils can also carry out work and bill the landlord.
Carbon monoxide alarms
Scottish guidance requires a carbon monoxide detector in every room with a fixed carbon-fuelled appliance — a boiler, gas fire, or gas heater (cookers used only for cooking are excluded) — and one in any bedroom or living room a flue passes through. Alarms must meet BS EN 50291, and since 1 February 2022 this sits within the Tolerable Standard that applies to every home in Scotland. Our engineers check CO alarms as part of a landlord visit and can fit them if they're missing.
Interlinked smoke and heat alarms
Not a gas item, but it comes up on every compliance visit: every Scottish home must have interlinked smoke alarms in the living room and every hall and landing, plus a heat alarm in the kitchen. If you're arranging a gas safety check, it's a good moment to confirm these are in place.
HMOs in Glasgow
If the property is a licensed HMO (three or more unrelated tenants), Glasgow City Council's licensing conditions require you to produce a current gas safety certificate as part of the licence, and inspections are more frequent. Keep your CP12 in the licence file.
What a gas safety check involves
For each appliance the engineer will check the gas rate and burner pressure, that the flue is effective and the products of combustion are being removed, that ventilation is adequate, that safety devices work, and that the appliance is physically safe and stable. They'll test the pipework for tightness. What they won't do as part of a CP12 is clean or adjust the boiler — that's a service. For a rental boiler you want both, ideally on the same visit, because a serviced boiler is one that doesn't break down in January and generate an emergency call.
What a landlord gas safety certificate costs in Glasgow
- Titan Heat landlord gas safety check (CP12), up to 3 appliances — £85 fixed
- Annual boiler service, can be done on the same visit — £89 fixed
- Typical Glasgow market rate for a CP12 — £60–£95
The £85 covers the boiler plus up to two further appliances such as a gas fire or hob, which is the vast majority of rental properties. Every check is carried out by a Gas Safe registered engineer and you receive the digital certificate the same day, ready to forward to your tenant or letting agent. We can also email it directly to the tenant to start the 28-day clock.
Booking as a landlord or letting agent
Book online on our service booking page, select the landlord gas safety option and enter the property postcode. If you manage several properties we can schedule them together and issue one invoice — contact us for portfolio pricing. You'll get a confirmation with a tracking link you can forward to the tenant so they know when the engineer is arriving.
Frequently asked questions
How often do I need a gas safety certificate in Scotland?
Every 12 months, for as long as the property is let. Use the two-month early window so the renewal date stays fixed.
Is a CP12 the same in Scotland as in England?
The gas safety check itself is identical UK-wide. What differs in Scotland is the enforcement route (the Housing and Property Chamber and Repairing Standard), landlord registration, and the carbon monoxide and interlinked alarm rules.
What happens if my tenant won't give access?
Take all reasonable steps: write to them, offer several dates, keep records. The regulations recognise reasonable steps, but you must keep trying. We'll work with your tenant directly to find a slot if that helps.
Do I need a gas safety certificate if there's only a gas hob?
Yes. Any landlord-provided gas appliance or pipework brings the property into scope.
Do I need a carbon monoxide alarm in a rental in Scotland?
Yes, in every room with a fixed carbon-fuelled appliance such as a boiler or gas fire, meeting BS EN 50291.
Can you do the gas check and the boiler service together?
Yes, and it's the sensible way to do it — £85 for the gas safety check and £89 for the service, on one visit. Select both when booking.
Do you cover letting agents across Glasgow and Lanarkshire?
Yes — Glasgow, Hamilton, Motherwell, East Kilbride, Wishaw, Airdrie, Coatbridge, Rutherglen, Cambuslang and surrounding areas.
