    I'm more than happy with the service received from PlumbProud. Right from the moment I enquired online about the cost of a new boiler, the service has been thorough. I received a call very soon after my enquiry and organised a next day visit. The representative was friendly and understood what i needed in terms of boiler size etc. He also talked me through the finance options available. Installation took a day and I was extremely impressed by the standard of work and professionalism of the two young men. They worked efficiently, politely and tidily to take out a monster of an old boiler and fit the new one in it's place. They took the boiler with them at my request leaving only the box for me to put with the recycling. The office staff are polite and friendly - working to get all the paperwork done and see to any modifications needed. Im very happy to recommend this company.
