“Phil was great. He fixed a boiler leak that two other plumbers hadn't managed to sort, and did it with no fuss at all. He did that as part of a regular boiler service with no extra charge on top. He's friendly, reliable and very easy to work with.”

“Recently we moved to a new property, and I decided to book a local engineer to service our combi boiler. From the very first contact, Phil was professional and offered a fair price for the job. Excellent service throughout.”

“We had a leaking pipe spilling water out of a cupboard in the kitchen. Phil was able to get to us quickly, diagnosed the problem and replaced the pipework all very efficiently and at a fair price. Problem solved and water back on within two hours with minimal fuss or mess. Very grateful!”
