Jame is a honest & professional plumber
Jamie, is a really professional and helpful plumber. His work is very thorough and he takes time to explain what needs to be done. I’m really pleased with his work and have booked additional work with him.Verified reviewerJob location: LL13RShafy R10 Gas Boiler Installation

New boiler installation and system upgrade
Four local firms quoted £4,200–£4,950 to replace my old floor-standing combi. Jamie at Osflow quoted £3,493 for a brand new Worcester 8000 40kW wall-hung (12-year warranty) and did a perfect job. Super tidy, really friendly, and the new boiler is silent and lightning fast. Couldn’t be happier 100 % recommend Osflow!Verified reviewerJob location: SY11RTim L
