What can go wrong, and how a good plumber avoids it
Gas work by someone who isn't registered
Ask for the RGI ID card. A real RGI carries one with a photo and a registration number.
A service that's just a look
The casing off and a flue gas reading. Ask what was tested.
Paying to repair a boiler that's done
On an old boiler, ask what a repair costs against a new one before you agree.

Boiler service and repair: questions
How often should a boiler be serviced?
Once a year. Gas Networks Ireland advises a yearly service by a Registered Gas Installer, and most boiler warranties need one.
Who can work on a gas boiler?
Only a Registered Gas Installer (RGI). It's the law in Ireland for any gas work in a home. Ask to see the RGI ID card.
How long does a boiler service take?
About an hour for most boilers. Longer if a part needs cleaning or replacing.
Should I repair or replace my boiler?
If it's over 15 years old, breaks down often, or a part is no longer made, a new condensing boiler usually makes more sense.
