What's checked

During the check, the engineer will typically:

  • Check gas appliances are burning correctly and working safely
  • Check flues and chimneys are clear and working
  • Check ventilation is adequate
  • Test safety devices
  • Check gas pressure and look for leaks
  • Record the results, including any defects and action taken

Records and timings

You must keep a record of each check and give a copy to existing tenants within 28 days, and to new tenants before they move in. Records should be kept for at least two years.

You can have the check carried out up to two months before the deadline and still keep the original anniversary date, which makes scheduling easier.

Carbon monoxide alarms

Rules on carbon monoxide alarms in rented homes have been tightened in recent years. In England, landlords must fit an alarm in any room used as living accommodation that contains a fixed combustion appliance, such as a gas boiler (gas cookers are excluded). Wales, Scotland and Northern Ireland have their own requirements, so check the rules where your property is.

Common questions

Is a gas safety check the same as a boiler service?

No. The safety check confirms appliances are safe; a service maintains the boiler. Many engineers do both in one visit.

What happens if a landlord doesn't get a gas safety check?

It's a criminal offence and can lead to fines or imprisonment, as well as putting tenants at risk. It can also affect a landlord's ability to regain possession in some cases.

Do tenants need to give access for the check?

Landlords should give reasonable notice and arrange access. Keep a record of attempts to arrange the check if access is difficult.
