The main risks gas safety checks protect against

  • Carbon monoxide poisoning from faulty appliances or blocked flues
  • Gas leaks and fire risk from damaged pipework
  • Explosion risk from undetected leaks
  • Legal liability for landlords who fail to meet safety obligations

Why we do not recommend assuming everything is fine

Common assumptionReality
“No smell, so it must be safe”Carbon monoxide is colourless and odourless — the only way to know is proper testing.
“The appliance looks fine on the outside”Most faults are internal and invisible without specialist inspection.

What it costs to skip regular checks

Gas safety incidents can be fatal, and even non-fatal carbon monoxide exposure can cause lasting health effects. Beyond safety, landlords who skip required checks face legal penalties and invalidated insurance.

Frequently asked questions

How often should gas safety be checked?

At least once a year, and landlords are legally required to have annual checks carried out.

What does a Gas Safe engineer check?

All gas appliances, pipework, ventilation and flues, testing for leaks, correct combustion and carbon monoxide risk.

Is this the same as a boiler service?

A gas safety check covers all gas appliances in the property, while a boiler service focuses specifically on the boiler — we can do both together.

Do not leave gas safety to chance. Call 020 7183 4810 today.
