If you manage rented homes in Glasgow, Lanarkshire, Renfrewshire or anywhere in Central Scotland, heating and gas safety are probably the compliance jobs that come round most often, and the ones tenants notice fastest when something goes wrong.
This guide pulls everything together in one place: the legal duties, how they apply in Scotland specifically, the problems we see in Glasgow tenements and older stock, and a practical system for managing gas safety across a portfolio without missed renewals or late-night phone calls.
It's written for letting agents and property managers, but landlords who manage their own properties will find it just as useful.
The short answer
- Every gas appliance, flue and the pipework a landlord provides must be safety checked by a Gas Safe registered engineer every 12 months.
- Existing tenants must get a copy of the gas safety record within 28 days of the check, and new tenants before they move in. Keep records for at least two years.
- In Scotland, the Repairing Standard requires the gas, heating and hot water installations to be in a reasonable state of repair and proper working order, and since March 2024 the property must have a fixed heating system.
- Any property with a fixed combustion appliance, such as a gas boiler or fire, needs a carbon monoxide alarm. Cooking-only appliances are excluded.
- If you're responsible for safety checks under your management agreement, the Letting Agent Code of Practice expects you to have proper systems and records in place.
The legal framework in Scotland
Gas safety and heating in Scottish rented homes is covered by several overlapping rules. Here's how they fit together.
Gas Safety (Installation and Use) Regulations 1998
These apply across Great Britain. Regulation 36 puts three main duties on landlords:
- Annual safety check. Every gas appliance and flue the landlord provides must be checked by a Gas Safe registered engineer at least every 12 months.
- Maintenance. Gas pipework, appliances and flues must be kept in a safe condition. HSE recommends servicing appliances in line with the manufacturer's instructions, usually once a year.
- Records. A gas safety record must be given to existing tenants within 28 days of the check and to new tenants before they move in, and kept for at least two years.
The gas safety record, often called a CP12 after the form many engineers use, has to include a description and location of each appliance and flue checked, the engineer's name, Gas Safe number and signature, the date, the property address, the landlord's or agent's name and address, and any defects found and the action taken.
The two-month window. Since 2018, a gas safety check can be done up to two months before it's due and the property keeps its original renewal date. That gives you a sensible window to arrange access without losing time off the certificate. If you use it, keep the records until two further checks have been done, so you can show the dates were met.
The Repairing Standard
The Housing (Scotland) Act 2006 sets the Repairing Standard for private rented homes. Among other things, it requires that the installations for the supply of gas and electricity, and for space heating and heating water, are in a reasonable state of repair and in proper working order.
The standard was updated from 1 March 2024. The changes most relevant to heating are:
- A fixed heating system is now required.
- Other fuels. The duty to keep gas and electricity installations in good repair now extends to any other type of fuel, so oil and LPG systems in rural lets are covered too.
Landlords must meet the Repairing Standard at the start of a tenancy and throughout it. If they don't, tenants can apply to the First-tier Tribunal for Scotland (Housing and Property Chamber), which can make a repairing standard enforcement order.
Carbon monoxide alarms
Scottish Government guidance is that a carbon monoxide alarm should be fitted in every rented home that has a fixed combustion appliance, excluding appliances used solely for cooking. In practice:
- one alarm in the room with the boiler or fire
- an extra alarm where a flue passes through a bedroom or main living room
- a boiler in a cupboard: the alarm goes outside the cupboard, 1 to 3 metres from the boiler
- alarms must meet BS EN 50291 and be either sealed long-life battery or hard-wired mains units
- replace them by their expiry date
Since February 2022, carbon monoxide alarms where there's a carbon-fuelled appliance have been part of the tolerable standard, which applies to all Scottish homes.
The Letting Agent Code of Practice
If you're a registered letting agent, the Code of Practice sets out how you should handle repairs and safety checks. The key points for gas and heating are:
- If you're responsible for statutory safety checks, such as annual gas safety inspections, you must have appropriate systems and controls in place and keep records of the work.
- You need written procedures for reporting repairs, with target timescales for routine and emergency repairs.
- Tenants must know who handles repairs and how to reach them out of hours, if that's part of your service.
- You should check contractors have the right qualifications and insurance, and hold copies of the relevant documents.
- You must tell landlords and tenants about delays, and the reason, as soon as possible.
Tenants and landlords can take a complaint about a letting agent to the Housing and Property Chamber, so good systems and records protect you as well as them.
HMOs and short-term lets
HMOs. Houses in multiple occupation need a licence from the council. A current gas safety record is a standard part of the application and renewal, and councils expect gas safety, carbon monoxide detection and heating to be in order throughout the licence period. Glasgow has a lot of HMOs, particularly around the universities and the West End, and these are often older properties with larger, more complicated heating systems.
Short-term lets. Scotland's short-term let licensing scheme includes mandatory conditions on gas safety. Glasgow's conditions, for example, require the licence holder to arrange an annual gas safety inspection of all gas pipes, flues and appliances, and say the property must not be let if an appliance fails until the necessary work is done. Carbon monoxide detection, electrical safety inspections at least every five years and a legionella risk assessment are also required.
Tenements and older stock: what we see in Glasgow and Lanarkshire
Scotland's rented housing has its own quirks, and Glasgow's tenements have more than most.
- Boilers squeezed into cupboards. Combi boilers fitted into hall cupboards and kitchen units with poor access and limited ventilation. Check the installation meets the manufacturer's clearances, and that the CO alarm is sited correctly outside the cupboard.
- Flue routes. Flues that run through ceiling voids or neighbouring spaces need to be visible and inspectable at the annual check. If the engineer can't see the flue, that's a problem to sort, not to ignore.
- Old gas fires and back boilers. Many tenement flats still have redundant gas fires or old back boilers. If they're not used, they should be properly disconnected and capped off by a Gas Safe engineer, not just switched off.
- Meters in the close. Gas meters in shared close cupboards, sometimes poorly labelled. Make sure you know which meter and emergency control valve serves each flat.
- Smart meter installations failing. We're seeing more smart meter installers refuse to fit a meter because the property failed a gas tightness test. When it happens in a let property, the tenant can be left without gas until a Gas Safe engineer finds and fixes the leak. Act quickly: the tenant has no heating or hot water.
- Condensate pipes. Condensing boilers with external condensate pipes that freeze in a cold snap. It's one of the most common winter call-outs and is usually preventable.
- Rural lets on oil and LPG. Cottages and farm properties across South Lanarkshire, Stirlingshire and Perthshire often run on oil. These need an OFTEC registered engineer, a service at least once a year, and a tank in good condition.
Void properties
The period between tenancies is the best time to deal with heating and gas safety, and the riskiest time to get it wrong.
- Check the gas safety record date. If the current record will expire during the next tenancy's first few months, think about renewing it during the void. New tenants must have a copy before they move in.
- Protect against frost. An empty property in a Scottish winter can freeze. Either keep the heating on a low frost-protection setting, or have the system properly drained down. Check your landlord's insurance, as many policies have conditions for unoccupied properties.
- Turning gas off. If the gas is turned off during a long void, a tightness test is needed before it's turned back on and appliances are relit.
- Fix the jobs tenants have lived with. Slow radiators, a boiler that loses pressure, a temperamental thermostat. They're quicker to sort in an empty property.
- Check the CO alarm is in date and correctly positioned.
Repairs and breakdowns: what good looks like
Heating and hot water failures are the repairs tenants care about most, especially in winter. A good process looks like this:
- The tenant knows what to do in a gas emergency. If they smell gas, they should turn off the supply at the meter if it's safe to do so, open windows and call the National Gas Emergency Service on 0800 111 999. Put this in your tenant information pack.
- Clear priorities. No heating or hot water, especially for vulnerable tenants or in cold weather, should be treated as urgent in your repair procedures.
- Access arranged properly. Give tenants proper notice before visits. Under the Housing (Scotland) Act, at least 24 hours' notice is needed for access to inspect or carry out repairing standard work, unless it's urgent. Check your tenancy agreement too.
- Approval routes agreed in advance. Agree with each landlord how much you can authorise for urgent heating repairs without waiting for approval, so a tenant isn't left cold while you chase an email.
- Keep everyone informed. Tell the tenant what's happening and when, and update the landlord.
- Records. Keep the engineer's report, any warning notices and the completion record on the property file.
Managing gas safety across a portfolio
The agents who never miss a renewal all do some version of the same thing:
- One register. Every property, its appliances, its gas safety record date and its next due date, in one place.
- Book early. Use the two-month window. Start arranging access around eight weeks before the due date, not the week before.
- One contractor, one process. It's much easier to manage when the same engineer knows your properties, your tenants and how you like records sent.
- Digital records. Records emailed to you as soon as the check is done, so you can send them to tenants within 28 days without chasing.
- Remedial work handled cleanly. Defects reported clearly, with a price for the landlord to approve.
- Combine visits. Do the boiler service at the same time as the gas safety check, so the tenant only has to give access once.
Your annual compliance checklist
Gas and heating:
- Gas safety check every 12 months, with the record given to tenants within 28 days, and to new tenants before they move in.
- Boiler and appliance servicing, usually annually, in line with manufacturers' instructions.
- Carbon monoxide alarms in place, correctly sited and in date.
- A fixed heating system in proper working order.
- Oil and LPG systems serviced by a suitably registered engineer.
Other safety items to keep on the same calendar:
- Electrical installation condition report at least every five years, and portable appliance testing for appliances you provide.
- Interlinked smoke and heat alarms, as required by the tolerable standard.
- Legionella risk assessment.
- A valid Energy Performance Certificate.
- Landlord registration with the council, renewed every three years.
What's coming: energy efficiency standards
The Scottish Government has proposed a minimum energy efficiency standard for private rented homes, with draft regulations consulted on in 2025. Under the proposals, the standard would apply to new tenancies from 2028 and to all private rented homes by the end of 2033, alongside a new style of Energy Performance Certificate. At the time of writing, these rules aren't yet law, so check the current position before planning major work.
Whatever the final rules, efficient, well-maintained heating will matter more for rented homes. A boiler that's properly serviced and set up costs tenants less to run and is less likely to break down mid-winter.

Frequently asked questions
How often does a rented property in Scotland need a gas safety check?
Every 12 months. You can have the check done up to two months early and keep the original renewal date.
Do I need a gas safety record if the property only has a gas hob?
Yes. The annual check covers all gas appliances and flues the landlord provides, including hobs and cookers, as well as the pipework.
Who is responsible for gas safety: the landlord or the letting agent?
The legal duty sits with the landlord, but it can be passed to a managing agent under the management agreement. If you've taken it on, the Letting Agent Code of Practice expects you to have the systems and records to deliver it.
Does the tenant's own gas cooker need checking?
The landlord's duty covers appliances and flues the landlord provides. Appliances the tenant owns aren't covered, but the pipework that serves them is, so the engineer should still check the installation pipework.
What happens if a tenant won't give access for the gas safety check?
Keep records of every reasonable attempt to arrange access, including letters, emails and appointment offers. HSE guidance expects landlords to take all reasonable steps. If access is still refused, get advice on your options under the tenancy.
Can the boiler service and gas safety check be done on the same visit?
Yes, and it saves the tenant giving access twice. They're different things: the safety check confirms the appliances are safe, while the service keeps them running properly.
A smart meter installer has left my tenant without gas. What now?
The installer found a problem with the gas installation, usually a leak. A Gas Safe registered engineer needs to find and fix it and retest the installation before the gas goes back on and the meter installation is rebooked. Treat it as urgent: your tenant has no heating or hot water.
Do you cover my area?
