Questions we get asked
What causes a gas hob that won't light on a gas boiler?
A wet or dirty burner cap and crown after cleaning or a spill
What normally puts a gas hob that won't light right?
Cleaning and reseating fixes many hobs; genuine FSD faults are a Gas Safe repair or, on older hobs, a replacement.
Is it safe to keep using the system with a gas hob that won't light?
A flame supervision device that has failed can allow unburnt gas to escape. It is a safety device, not an inconvenience, and must not be bypassed.
