Quick and Reliable Service
Our boiler stopped heating in the morning, so I contacted Graeme. He managed to come round that same afternoon, quickly identified the problem and fixed it. Really pleased with the prompt, efficient and professional service. Would definitely recommend!Verified reviewerJob location: RM210 Central Heating

Would 100% recommend!
Where to begin! Had a few bad experiences where plumbers don’t turn up or do but you never get the quote which is a huge letdown! Graeme is definitely not that! He is polite, punctual, arrived exactly when he said and got straight on with the job. Can’t really ask for more! If anyone is looking for a reliable plumber then look no further. Massive thumbs up from us.Verified reviewerJob location: RM118.67 Central Heating

Brilliant plumber for the Romford area
I would highly recommend Graeme. Very punctual and reliable. I have used his plumbing services for years in maintaining my boiler and other plumbing jobs needed in the home. I have not used any other plumber. He cleans up after any job is complete. Pricing is very fair with him.Verified reviewerJob location: RM110 Gas Boiler Servicing / Repair
