Boiler Installation
We specialise in installing high-efficiency gas boilers, including Worcester Bosch models. Our engineers ensure safe, compliant installations with minimal disruption. Customers benefit from extended warranties through our accreditation, improved energy efficiency, and long-term cost savings on heating bills.
Gas Safety Checks
Annual gas safety inspections are conducted for rented properties, complying with legal requirements. We issue Gas Safety Certificates and can combine boiler servicing during the same visit, ensuring tenant safety and landlord compliance.
Boiler Servicing
Regular boiler servicing prevents breakdowns and extends system lifespan. Our comprehensive checks include pressure testing, flue gas analysis, and component inspections, ensuring optimal performance and safety for residential and commercial properties.
Emergency Repairs
We offer urgent boiler and heating repairs for critical failures. Our rapid response team addresses issues like leaks, pressure loss, and system failures, restoring heating and hot water with minimal downtime for homes and businesses.

Report
I would highly recommend Andrew. He provided a fast and free diagnosis of our boiler issue and was able to complete a full installation of a new boiler within 4 days of the initial diagnosis.
Andrew gave us a variety of options for the work, even directing us to different services which may have been more viable than using his services- testiment to his honest nature as a tradesman which can be hard to find. His rates are very reasonable and his professionalism is superb. Trustworthy and reliable service from start to finish.

Was able to come the same day and didn't charge an emergency call out fee. Managed to run some tests to identify the problem and get my hot water back up and running within an hour and the charge was much less than I expected.

We would definitely recommend Andrew. He has never let us down all the years since he installed and maintained our boiler in our rental property in Dunstable. We rely on him to remind us when services, checks etc are due and he is always there when he says he will be. Finding a good, reliable plumber is like gold dust and you have got all that here.

I was really pleased with the support I received via telephone. Really knowledgeable of his clients and was able to remember my property and boiler very quickly. Have honest advice and was genuinely really helpful and focussed on me rather than potential business. Really pleased and will contact again if needed (hopefully not)...but would definitely recommend

We've used Andrew for our home in Leighton Buzzard for years. He's always been great to deal with, professional, explains all the issues and options and we've never had a single problem with his work. He's always responsive with emails etc also. We wouldn't hesitate to recommend this company.
