Working in Barnet
We cover every part of Barnet, including EN4, EN5, HA8 and 7 more postcode districts, and nearby Potters Bar (3.1 miles) and Borehamwood (3.3 miles).
London homes in Barnet often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Barnet water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean. If you have bought a vanity unit for your Barnet bathroom, fit-only installation covers connecting the tap and waste and testing for leaks.
Water across much of Greater London is very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Testing for leaks and checking the trap holds its seal
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
Decisions to make first
Width
Compact units around 400 mm wide suit cloakrooms; family bathrooms often take 600 to 800 mm for one basin and 1200 mm or more for two.
Wall-hung or floor-standing
Wall-hung units leave the floor clear and are easy to clean under, but need a strong wall. Floor-standing units hold more and suit weak or uneven walls.
Rules that apply in England
In England, the tap and supply pipework come under the Water Supply (Water Fittings) Regulations 1999. A new waste connection to the soil stack can be Part H work, and adding a light to the unit or above it is notifiable under Part P.
