Boiler Repairs
Our specialist engineers provide comprehensive boiler repairs for all makes and models. With same-day response and no callout charges during working hours, we prioritise first-time fixes using diagnostic expertise rather than part replacement. Our Gas Safe registered team handles both modern condensing boilers and older back boiler systems, maintaining a 95% success rate in single-visit repairs through well-stocked service vehicles and technical proficiency.
Boiler Servicing
We offer two service levels for modern condensing boilers: defined scope safety checks at 70 and full strip-down services from 120. Our procedures exceed basic requirements by including combustion chamber cleaning and hydraulic system optimisation. For older standard efficiency boilers, we provide 70 all-inclusive services covering flue integrity, burner pressure checks, and condensate path maintenance, with specialist back boiler servicing available at 120 including front fire inspection.
Landlord Certificates
We provide Gas Safety Certificates and electrical safety checks for rental properties. Our registered engineers conduct thorough inspections of gas appliances, flue systems, and electrical installations, delivering documented compliance reports within 24 hours. The service includes both visual inspections and technical testing to meet HSE regulations, with digital certificate delivery and landlord-specific advice on maintenance requirements.
Powerflush Systems
Our powerflush service removes sludge and scale buildup from central heating systems using high-velocity water flow. The process restores efficiency by clearing blockages in radiators and pipework, typically completed within 4-8 hours depending on system size. We include chemical treatment and inhibitor addition to prevent future corrosion, with before-and-after performance comparisons provided to demonstrate improved circulation and heating effectiveness.
Commercial Catering
We specialise in commercial gas installations and safety certifications for catering businesses. Our services include kitchen boiler systems, gas safety compliance, and emergency repair contracts. Engineers hold commercial gas qualifications for large-scale installations, providing documented maintenance schedules and 24/7 breakdown support tailored to hospitality sector requirements, with safety certificates valid for insurance and regulatory purposes.

Report
Ming came out to check my boiler last week (09/12/21) which was completely dead. Within 20 mins of arrival he diagnosed the problem and informed me what the issue was. Due to the problem I had (leaking flow elbow and damage to the fan and possible PCB issue) and the availability of parts he said the best option would to call Worcester Bosch and ask for a fixed price out of warranty repair. The reason being that they would have the parts available on their van when they came out. This is the reason for the 5 star review, he could have said "you need a new boiler at approx. 2k - 2.5K" and I

Ming serviced my Heating Interface Unit in my flat that is connected to the buildings communal heating plant. It is very difficult to find engineers that know how these units work and can service them. Ming was brilliant and did an excellent job. He came on time with full protection including overshoes and was very polite. He told me how much the service would cost before he came and is very reasonably priced. I can highly recommend Ming.
