A let property with no gas appliances does not need an annual landlord gas safety check, and only a Gas Safe registered engineer may cap off the supply. Capping ends the appliance check. It does not end your duty to keep the gas pipework inside the property in a safe condition. This page covers letting in England under the Gas Safety (Installation and Use) Regulations 1998 as amended, which apply across Great Britain. It separates three jobs that are often confused: capping the pipework, removing the meter, and disconnecting the property from the gas main.
Does capping off the gas supply end the annual gas safety check in a let property?
Once no gas appliance is left in the let property, the annual landlord gas safety check no longer applies. HSE states that where only pipework runs through a property and there are no gas appliances, no annual safety check is required. The same applies to a flue that passes through without an appliance, although that flue must still be kept in a safe condition.
Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 as amended ties the 12-month check to relevant gas fittings. A relevant gas fitting means an appliance or a flue serving one. With neither in place, there is nothing for the check to cover. The duty restarts the moment a gas appliance goes back in. Our guide on gas safety certificates where there are no gas appliances sets out the pipework side in more detail.
Who is allowed to cap off the gas supply at the meter?
Only a Gas Safe registered engineer may cap off the gas supply in a rented home. HSE is clear that gas work in domestic properties by anyone else is unlawful. Capping covers more than a single valve.
- Disconnecting and removing a boiler, fire or cooker
- Sealing the installation pipework that ran to the appliance
- Any work on the flue the appliance used
- Testing the remaining pipework for tightness
Ask to see the engineer's Gas Safe ID card before the work starts. The front carries a photo, a registration number and an expiry date. The back lists the categories of work the engineer is qualified for. An appliance that has been isolated on safety grounds must not be reconnected until the fault is put right, and using an appliance known to be unsafe is a criminal offence.
Capping the pipework or disconnecting from the gas main: which one do you need?
Capping the pipework at the meter and disconnecting the property from the gas main are two different jobs handled by two different parties. Ofgem separates a voluntary disconnection, which the customer requests from the gas transporter, from a health and safety disconnection, where the meter is pulled over safety concerns.
| What it covers | Capping at the meter | Disconnection from the gas main |
|---|---|---|
| Who carries out the work | A Gas Safe registered engineer, working on the installation pipework inside the property | The gas distribution network, or an independent provider acting on a request |
| What stays on site | Meter and incoming service pipe remain; the pipework beyond the meter is sealed | The connection to the gas main is taken out, so no supply reaches the building |
| How you arrange it | You book a Gas Safe registered engineer directly | You apply to the gas distribution network; the network charges for the work |
| Where the meter fits in | Separate step: suppliers offer meter removal to households that will not use gas | Normally dealt with as part of the disconnection request |
| Bringing gas back later | Reconnection at the capped point by a Gas Safe registered engineer | A fresh connection has to be applied for and laid again |
Capping suits a property that may take a gas appliance again, for example a flat moving to electric hot water while the landlord keeps options open. Full disconnection suits a building that will never use gas again. Ofgem publishes a page that helps you identify your gas distribution network operator before you apply.
Which landlord duties continue after the gas appliances in a let property have gone?
The duty to keep gas pipework in a safe condition carries on even with every appliance removed and the supply capped. HSE says this normally means inspecting the pipework at regular intervals and carrying out any repairs needed. All maintenance and repair work on that pipework must be done by a Gas Safe registered engineer.
The boundary matters. Installation pipework from the meter onwards sits with you as landlord. The service pipework outside the property, up to the meter, belongs to the gas network operator. There is no formal legal requirement to keep maintenance records for pipework, but you should be able to show that inspection and repair happened. Old gas safety records still have to be kept for two years from the date of the check.
Capping the supply ends the annual appliance check. It does not end the pipework duty, and it cannot be passed to a tenant through a tenancy agreement.
Does a rented home in England still need a carbon monoxide alarm once the gas boiler is removed?
A carbon monoxide alarm is required in England in every room used as living accommodation that contains a fixed combustion appliance, gas cookers excepted. That rule comes from the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 and has applied since 1 October 2022. Take the gas boiler out and that particular trigger falls away with it.
Other fuels keep the duty alive. A wood burner, a solid fuel stove or an oil boiler is still a fixed combustion appliance, so the room it sits in still needs an alarm. Smoke alarms on every storey used as living accommodation stay required regardless of fuel. A fault reported by a tenant must be repaired or the alarm replaced as soon as reasonably practicable. The carbon monoxide alarm rules for rented homes in England go through the room-by-room detail.
What has to be arranged before re-letting a property where the gas was capped?
Before new tenants move into a property, every gas appliance and flue must be safe and covered by a current gas safety record, with a copy given to the tenant before they take up occupation. A capped property with no appliances has nothing to record. The position changes the moment an appliance is reinstated or left behind.
- An appliance a former tenant leaves behind becomes your responsibility if you keep it, which brings back the annual check and maintenance duty
- Only removal by a Gas Safe registered engineer ends that duty
- HSE advises having pipework inspected and tested for tightness after a tenant moves out
- Where tampering or vandalism is suspected in an empty property, HSE advises a fresh check by a Gas Safe registered engineer before anyone moves in
Clarify who owns any remaining appliance before the new tenancy starts. Our guide on whether you need a new gas safety certificate between tenants covers empty periods and handover.
What replaces heating and hot water once a let property stays off gas?
An electric heat source and a mains-pressure cylinder are the usual route for a let property that stays off gas. Unvented cylinders such as Megaflo are fed straight from the cold water main and can be heated directly by immersion or indirectly. Approved Document G in England requires at least two independent safety devices on an unvented cylinder in addition to the control thermostat, with discharge pipework taken to a visible, safe place.
Two other duties move when the system changes. Your legionella risk assessment should be revisited, because temperature is the main control and redundant pipework left capped in place can become a dead leg that stands still. Energy efficiency also shifts: under the minimum standard for privately rented homes in England and Wales, EPC band E has applied to continuing tenancies since 1 April 2020 unless an exemption is registered, and changing the heating type changes the EPC.
If a gas appliance stays in the property, or one goes back in later, you can book the annual check through our landlord gas safety certificate service.
