What should I do if I smell gas?
Call the Northern Ireland Gas Emergency Service on 0800 002 001 straight away. Do not use switches or naked flames, open doors and windows, and turn off the gas at the meter if you can.
Why has my boiler lost pressure?
Usually a small leak, a faulty pressure relief valve or after bleeding radiators. You can often top it back up to 1-1.5 bar using the filling loop. If it keeps dropping, book an engineer.
How often should my boiler be serviced?
Once a year. Most manufacturers require an annual service to keep the warranty valid, and it catches faults before the cold weather arrives.
Should I repair or replace my boiler?
If your boiler is over 12 to 15 years old, needs an expensive part or breaks down often, replacing it is usually better value. A modern boiler can also lower your gas bills.
