Questions people ask
How much does a gas safe engineer cost in Cardiff?

How often do landlords need one?
Every 12 months, and tenants need a copy.
Is it the same as a boiler service?

What if something fails?
The engineer will explain and may turn off anything dangerous. You'll get a price to fix it.
