Dangerous appliances found in thousands of homes

Gas watchdog found risky appliances in inspections

One in five homes investigated by the Gas Safe Register had a gas appliance which could cause carbon monoxide poisoning or an explosion.

Hundreds of thousands of people could be at risk of serious injury or death because they are using cowboy gas fitters, says the watchdog. And botched jobs cost the UK an estimated £100m to repair.

Gas fitting

By law, all gas workers have to be on the Gas Safe Register and if they’re not, there’s no guarantee that they’re trained to do the job.

People who are concerned about a gas installation can call the Gas Safe Register, which can come to inspect the property. It’s reported that, of the thousands of inspections it has carried out, one in five properties had an unsafe gas appliance. 

The Gas Safe Register says that about 250,000 illegal gas jobs are done each year, though the figure could be higher. 

The watchdog also published a survey which revealed that one in 10 people would ask an unqualified friend or relative to do a gas job.

Which? investigation into boiler servicing

One way to ensure your gas appliances stay safe is to get them serviced by a Gas Safe Registered engineer every year. However, it helps to know what to expect.

Home Editor Liz Edwards says: ‘When Which? investigated boiler servicing we found that not all gas fitters were doing the necessary safety checks. To get a better understanding of what a boiler service should involve check out our video guide to getting a good boiler service. This covers the basic checks that a gas engineer should do, so you know what to expect.’

If you’re concerned about gas work carried out in your home then contact the Gas Safe Register on 0800 408 5500.
