What does a new shower cost in Barnet?
Our guide price for a new shower in Barnet is £550–£4,400 including VAT. Prices in London run at about 25% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Barnet
We work right across Barnet — EN4, EN5, HA8 and 7 more postcode districts — and in neighbouring Potters Bar and Borehamwood.
In Barnet, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. We test pressure and flow at Barnet surveys before recommending a shower, so you know how it will perform before you buy. If you are replacing a failed electric shower in Barnet, we check whether the existing cable and circuit suit the new unit.
Water across much of Greater London is very hard. If your supply in Barnet is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A check of your hot-water system, water pressure and flow rate
- Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
- New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank
- Electrical connection by a qualified electrician, tested and certified
Decisions to make first
Exposed or concealed
An exposed bar valve fixes onto the tiles and is easy to service. A concealed valve sits in the wall for a cleaner look but needs careful setting-out and a plan for access.
Thermostatic mixer
Blends hot and cold from your system and holds the temperature steady when someone runs a tap. The usual choice with a combi or an unvented cylinder.
Rules that apply in England
In England, an electric shower usually needs its own dedicated circuit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, and a new circuit is notifiable under Part P. The Part G limit of 48 °C applies to a new bath in a new dwelling or one created by change of use, not to a shower, but a thermostatic valve gives similar protection. An unvented cylinder fitted to improve the shower must be installed by a G3-qualified installer.
