Working in Welling

We cover every part of Welling, including DA6, DA15 and DA16, and nearby Bexley (2.3 miles) and Eltham (2.5 miles).

In Welling, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Whether your Welling bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Welling home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Most of Greater London has very hard water. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A check of the floor construction, the room's heat loss and where the thermostat and supply will go
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician

Decisions to make first

Floor heating and towel rail

Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.

Mat or loose cable

Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.

Rules that apply in England

In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.

Is the water hard in Welling?

Is electric underfloor heating expensive to run in a bathroom?

Running cost depends on the heated area, the insulation under the mat, how long it runs and your electricity tariff. As an example, a 150 W per m² mat covering 3 m² draws 450 W, so two hours a day uses about 0.9 kWh. A timer and floor sensor stop it running when nobody is using the room.
