Bathroom Tap Replacement in London: Cost Guide for 2026

Replacing bathroom taps in London varies in cost depending on tap type, access, and whether the waste needs replacing at the same time. This guide gives current prices and explains what is included in the cost.
What Affects the Cost of Bathroom Tap Replacement in London
The cost of replacing a bathroom tap in London depends on four main factors: the type of tap being fitted, whether the tap is supplied by the plumber or the customer, access to the isolation valves and back nuts under the basin, and whether the click-clack waste or pop-up waste needs replacing at the same time. Each of these factors adds to or reduces the total cost compared to a straightforward supply-and-fit job on a standard basin with good access.
Tap type is the primary cost variable. A standard chrome pillar tap pair costs less than a designer mixer in brushed brass or matte black. The fitting labour is similar regardless of tap finish, but the supply cost varies significantly. Customers who wish to supply their own tap — purchased from a retailer or salvaged from a previous property — avoid the supply cost and pay only for labour and any necessary additional parts.
Standard Basin Tap Replacement Costs
Replacing a pair of basin pillar taps (hot and cold separate) with a like-for-like replacement supplied by the plumber costs £150 to £200 including standard chrome taps, new flexi-hoses, labour, and all checks. Replacing with a basin mixer tap — a single lever or two-handle mixer on one body — costs £180 to £250 including a mid-range mixer tap, new flexi-hoses, and a cover plate for the redundant second tap hole where applicable. If the customer supplies the tap, subtract approximately £50 to £80 from the supply-and-fit cost.
Basin taps on a countertop basin or semi-recessed basin require longer tap tails to pass through the thicker basin deck. Not all standard taps are supplied with tails long enough for countertop basins — we check and source compatible taps or tap extensions before the installation visit to avoid delays. Countertop basin tap replacement costs £200 to £280 where specialist longer tails are required.
Click-Clack Waste Replacement
The click-clack waste is the push-button drain plug mechanism at the centre of the basin outlet. It is typically replaced at the same time as the tap when the existing waste is corroded, seized, or does not seal correctly. Replacing the click-clack waste on the same visit adds £30 to £50 to the total cost and avoids a return visit. We recommend replacing it as a matter of course on basin tap replacements where the waste is more than five years old or shows visible wear.
Bath Tap Replacement Costs
Replacing a pair of bath taps — either pillar taps or a bath mixer tap — costs £150 to £280 including labour. Bath taps use 3/4-inch BSP connections and are secured through the bath deck from below with back nuts. Access to the back nuts from below the bath panel is required. In many London bathroom installations, the bath panel is fixed and requires partial removal. We assess access at the start of the visit and factor any panel removal into the time allocation. Thermostatic bath shower mixer tap supply and fit costs £250 to £400 depending on the model.
