Posted 04 June
Job location: SP10Clear concise information given including breakdown of quote, turned up when they said they would, friendly and efficient. Definitely would use again 10 New boiler
Posted 20 May
Job location: RG24The 2 lads spent the day fitting a new boiler. Not an easy job 4th floor not able to get a cherry picker for the flue no complaints though. The boss checked in to check on progress no issues. With the new boiler being slightly larger it was not possible to replace the wall unit the original was housed. Put down protection for the floor and hovered. Very happy with the results10 Recommended

10 Highly recommended
Posted 13 March
Highly recommend this firm, great communication and quality work! In 2025, they refurbished my en-suite bathroom with a new shower, radiator and flooring. My house is quite old (1901) so involved quite a lot of complex pipe work in the project as it was not done correctly previously. Mark came up with the visualisation on how it could look and the final result has exceeded my expectations. The team were reliable, friendly and communicative. My go to plumber since then!Verified reviewerJob location: SP10 10 Excellent Service from company & George Backalic
Posted 07 March
We had George, he arrived to refit a radiator in my home and was absolutely fantastic from start to finish. He turned up promptly, was polite throughout, and carried himself with real professionalism. The job was completed quickly, neatly, and with clear attention to detail. It’s refreshing to meet someone who takes such pride in their work. I wouldn’t hesitate to recommend George to anyone looking for reliable, high‑quality service.Verified reviewerJob location: SP10
