Working in St Albans

In St Albans we cover AL1 and AL2; we also cover Harpenden, 4.7 miles away, and Hatfield.

In a city the size of St Albans, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Whether your St Albans 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 St Albans bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.

Supplies across most of Hertfordshire are very hard. 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

Bringing the system up to temperature gradually once the adhesive and grout have cured
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
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 floor sensor set between the heating runs and wired back to the thermostat

Decisions to make first

Floor finish

Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.

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.

Do you cover AL1 and AL2 in St Albans?

Yes. We cover all of St Albans, including AL1 and AL2, and nearby Harpenden, Hatfield and Hemel Hempstead. Survey visits are free and arranged at a time that suits you.

Is the water hard in St Albans?

Is underfloor heating enough to heat a bathroom on its own?

In a well-insulated bathroom with most of the floor open, it often is. In a small room, the bath, WC and furniture cover much of the floor, so the heated area may be too small to be the only heat source. A heated towel rail alongside is the usual answer.
