Good to Know
How often should my boiler be serviced?
Once a year. An annual service keeps your boiler safe, efficient and within its manufacturer guarantee.
Do you cover emergency breakdowns?
Yes. We offer same-day call-outs for no heating or hot water across the area.
Are your engineers qualified?
Yes. Our engineers are fully qualified, registered for gas work and insured.
Should I repair or replace my boiler?
If your boiler is over 12 years old or keeps breaking down, a new A-rated boiler usually pays for itself. We'll advise honestly.
Can you fit air source heat pumps?
Yes. We design, install and commission heat pump systems and can advise on available schemes.
