Published planning figures
Current UK market guidance gives example whole-house plumbing costs of around £14,500 for a 2-bed property and £21,500 for a 4-bed property. These are broad planning figures, not fixed rates.
Define the scope before comparing prices
• Hot and cold water distribution.
• Heating pipework and radiators.
• Waste and soil pipework.
• Bathrooms and kitchen connections.
• Boiler or cylinder work.
• Making good after access.
Why property condition matters
Older homes may contain obsolete pipe materials, awkward routes or previous alterations that only become visible once work starts. A clear contingency is sensible on major replumbing projects.
