Boiler Servicing
Regular boiler servicing prevents breakdowns and extends system lifespan. Our Gas Safe engineers conduct comprehensive checks, cleaning components and identifying potential issues. This proactive approach ensures optimal performance, safety compliance, and peace of mind for homeowners, landlords, and businesses across Bedfordshire and Buckinghamshire.

We provide legally required gas safety checks for rental properties, issuing certified Gas Safety Records. Our inspections cover all gas appliances, ensuring compliance with regulations and tenant safety.

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.

I have been using Andrew as our Plumber for 6 years. He undertakes our annual boiler service and any maintenance required. His service is always exceptional from start to finish. He is not only responsive and reliable but honest and trustworthy too. His prices are always fair and he goes above and beyond to provide excellent service to his clients. I highly recommend him.

First class service. Great communication. Friendly, helpful and honest. Could have sold me a repair that would have made him a lot of money but recommended a cheaper way of doing it. Not often you see such integrity. Cant recommend highly enough.
