Underfloor Heating Installation in London

Underfloor heating installation in London: what the price includes

• 01
  Screed, low-profile or between joists

  A new extension takes pipe in screed and performs best. A retrofit onto an existing floor takes a low-profile overlay of 15–20 mm, which affects door heights and thresholds. A suspended timber floor takes spreader plates between the joists. We survey before specifying, because the floor decides the system.

• 02
  Heat loss calculated room by room

  Underfloor output is limited by floor surface temperature, you cannot simply turn it up. If a room's heat loss exceeds what the floor can deliver, insulation or a supplementary emitter is part of the answer, and it is far cheaper to know that now than after the screed is down.

• 03
  Manifold, blending and zoning

  A blending valve drops flow temperature from the boiler circuit to the loop temperature, and the manifold balances each loop so no room runs cold. Zoned actuators and per-room stats are the difference between comfortable and expensive to run.

• 04
  Pressure-tested before anything covers it

  Loops go in continuous, with no joints under the floor, and are pressurised and held before screeding or boarding. A leak found at that stage costs an hour. Found later it costs a floor.

• 05
  Floor finish matters

  Tile and stone are ideal, engineered timber works within a temperature limit, and thick carpet or heavy underlay can insulate the system into uselessness. We will tell you the tog ceiling for your build-up before you order the flooring, not after.

Local conditions we work around

Underfloor heating and London water need planning. The blending valve and manifold that control flow temperature are exactly the components hard water scales, so we specify serviceable parts and treat the system properly at commissioning rather than sealing a problem under a floor that cannot be lifted. In period and listed properties the other constraint is floor build-up: adding height changes door and stair thresholds, which in a listed interior is a consent question before it is a heating one.
