Why Choose Underfloor Heating

Why Lambeth Homeowners Choose Underfloor Heating

Underfloor heating is one of the most requested upgrades across the borough’s mix of period conversions, terraces and new-build towers. Here’s why.

Frees up wall space lost to radiators

Removing radiators is a common request during kitchen extensions across Brixton and Herne Hill, where extra wall space for units and windows matters more than in the original layout.

Low-profile options for limited floor height

Victorian conversion flats in Clapham and Streatham often have limited ceiling height below. Low-profile electric mats add minimal floor build-up compared to a full wet system.

Even, comfortable heat throughout the room

Unlike radiators, underfloor heating warms the whole floor area evenly, removing cold spots — particularly noticeable in larger open-plan kitchen extensions.

Runs efficiently with heat pumps

Underfloor heating operates well at the lower flow temperatures produced by air source heat pumps, making it a natural pairing for heat pump upgrades in the borough's larger houses.

Lambeth underfloor heating context: New-build towers around Vauxhall and Kennington are often specified with wet underfloor heating from the outset, while Victorian conversions in Clapham and Streatham are more commonly retrofitted with low-profile electric systems in bathrooms and kitchens. Larger houses in Herne Hill and Streatham Hill frequently combine whole-floor wet systems with a heat pump upgrade.

Our Clapham conversion flat has low ceilings downstairs so we were worried about losing height in the bathroom. Fitted a low-profile electric system that barely raised the floor and heats up in minutes.

FAQs

Underfloor Heating in Lambeth — FAQs

Yes. We cover the entire Lambeth borough including Brixton, Clapham, Stockwell, Vauxhall, Kennington, Streatham, Herne Hill and Waterloo — postcodes SW2, SW4, SW8, SW9, SE11 and SE24. Our engineers are based locally across South London.

Electric underfloor heating for a single room starts from £650. Wet underfloor heating starts from £1,650 for a single room, or from £3,800 for a whole ground floor. All prices are confirmed before work begins.

Wet systems suit larger areas, extensions and new-build flats where floor build-up allows, and run efficiently alongside a boiler or heat pump. Electric systems suit smaller rooms like bathrooms and retrofits where raising the floor isn't practical, common in Clapham and Streatham conversions. We'll recommend the right option on survey.

Yes. Underfloor heating fitted during a rear extension is one of the most common jobs we do in Brixton and Herne Hill, since it frees up wall space that would otherwise be taken by radiators and ties in neatly with new screed or floor finishes.

No. There is no call-out charge, no zone surcharge and no area uplift for any postcode within Lambeth. Our fixed prices are identical whether you're in Brixton or Vauxhall.

Yes. Underfloor heating runs efficiently at the lower flow temperatures heat pumps produce, and we're increasingly asked to design and size systems for heat pump installations across the larger houses in Herne Hill and Streatham Hill.

Yes. For cold spots, leaks, faulty thermostats or a system that won't heat up, we offer same-day diagnosis and repair across all Lambeth postcodes, with no additional out-of-hours charge on top of the fixed price.
