Boiler help for Mildenhall

How do I get a quote from a boiler engineer in Mildenhall?

Mildenhall has 27 registered heating businesses in this directory, though the engineers who quote are not necessarily among them. It is free and there is no obligation.
Should I repair or replace my boiler?
A repair makes sense on an otherwise sound boiler. Replacement is usually the better value once a boiler is past 10 to 12 years old, parts are hard to get, breakdowns are frequent, or efficiency has dropped. Ask the engineer to price both where a repair is borderline.
Is a new boiler covered by a warranty?
New boilers typically carry a 5 to 12 year manufacturer warranty. It is conditional on the boiler being registered shortly after installation and serviced every year by a Gas Safe registered engineer, so keep your service records.
What should I do if I can smell gas?
Turn the gas off at the meter, open windows, avoid light switches and naked flames, leave the property, and call the National Gas Emergency line on 0800 111 999. Do not wait for a routine appointment.
