    Plumbing Repairs

    Premium prices

    The good: diagnosed the issue promptly, arrived quickly (even though mine was a non emergency). The bad: The price was £600 for a job I later found out would cost £350 at the top end. I felt a bit pressured to agree on the price over the phone, as the workman are standing over your shoulder and yo have no chance to check for a fair comparison. Basically, if you want to pay a premium to get the job done fast then your at the right place, alternatively, you will get a better price elsewhere.

    General Plumbing

    Posted 05 November 2025

    Unethical and dishonest

    I was told over the phone that the call-out fee was £60 and that any additional work would be quoted before proceeding. However, when the plumber arrived, he just tightened a few bolts, which took less than two minutes, and then charged me £250. Even though he never gave me a quote and I never agreed for the work to be carried out. This feels completely dishonest and unethical. When I challenged him on this he became very insistent and rude and demanded that I pay him on the spot. Please avoid this company at all cost! They clearly intend to fool people.

    Emergency Boiler Repair

    I returned from a trip to find my boiler was not working,I needed a repair quickly and while I completely expected to be charged commensurately I was shocked when i was charged £634 for an hour service requiring the replacement or 2 fuses. Unless money is no object be careful when using someone like this that you dont know,ironically some of their testImonials include 'great prices'
