Estimated cost breakdown
How this estimate is calculated
Fittings, surfaces and services are separated. Changing the layout is priced independently from the visual specification.
Location adjusts installation-heavy work. London and the South East adds 25% to labour, plumbing, waterproofing and heating/ventilation allowances.
Contingency stays visible. Choose 10%, 15% or 20% rather than hiding uncertainty inside the rate.
