I have found Sam, Cody, Zoe and their Team, amazing to deal with. They have also done an excellent and prompt job of installing a New Vaillant Boiler and 8 New Radiators in my home in a day and a half, with no mess left at all. I would highly recommend them for Gas Engineering and Other Plumbing work!

Why Choose Us For Boiler Servicing?
Manufacturer-approved servicing
Accreditations with Viessmann and Vaillant mean services meet manufacturer standards, protecting warranties and using approved parts.
Safety and compliance
All work is completed by Gas Safe-registered engineers with clear service records and documented safety checks to keep your property compliant.
Specialist heat pump support
As HPIN members we offer tailored maintenance for air-source heat pumps alongside gas boiler servicing, preventing performance drops and inefficient running.
What our servicing covers A full annual or routine service includes inspection of the burner and heat exchanger, combustion/efficiency checks where applicable, flue and condensate inspection, pressure testing and controls verification. For combi and system boilers we check seals, valves and expansion components; for air-source heat pumps we inspect refrigerant circuits, electrical connections and system controls.
Why the report matters Every service includes a written report that documents condition, test readings and recommended work. That report supports warranty requirements, landlord enquiries and helps plan preventative maintenance so boilers and heat pumps run reliably and efficiently year after year. Emergency repairs and ongoing aftercare are available if a fault is found.

Frequently Asked Questions
How often should I have my boiler or heat pump serviced?
We recommend an annual service for gas boilers and a yearly health check for air-source heat pumps. Annual servicing keeps safety checks up to date, helps maintain efficiency and supports manufacturer warranty conditions.
Does a service affect my boiler warranty?
Yes, using manufacturer-accredited engineers and approved parts helps protect your warranty. We follow Viessmann, Worcester Bosch and Vaillant procedures and provide a written service report you can retain for warranty records.
What happens if you find a fault during the service?
We’ll explain the issue on site and include it in your service report with recommended repairs. For urgent failures we offer emergency repair cover and can schedule follow-up work by Gas Safe engineers to restore safe operation quickly.
Do you service both gas boilers and heat pumps?
Yes. Our team are Gas Safe-registered for gas appliances and HPIN-qualified for air-source heat pumps, so we carry out specialist maintenance for both systems using the correct checks and procedures for each technology.
How long does a boiler service usually take?
Most routine services take between 45 minutes and 90 minutes depending on the appliance type, accessibility and any additional checks required. If extra remedial work is needed we’ll provide a clear estimate before starting.
