"Boiler packed in on a Sunday evening in January. Castle Plumbing had an engineer with us within two hours. Fixed the same night. Brilliant service — I genuinely couldn't ask for more. Have used them for the annual service ever since."
"Had the whole bathroom stripped and refitted. The team were tidy, professional, and kept us informed every step of the way. The finished result is absolutely stunning. Well within budget too. Would not hesitate to recommend them."
"Used Castle for a full rewire of our 1960s property. They were methodical, explained everything clearly, and made good all the plaster before leaving. NICEIC certificate issued on the day. Competitive price and genuinely nice people to deal with."
"As a landlord with six properties, I need contractors I can rely on. Castle Plumbing handle all my CP12s and EICRs. They remember when certificates are due and contact me in advance. Saves me enormous amounts of time and stress. Highly recommended."
