Underfloor Heating
Installation London
Wet underfloor heating systems for new builds and retrofits across London. The most comfortable, efficient way to heat your home — installed to the highest standard.
Heat that rises from
the ground up
Underfloor heating warms the floor surface evenly across the entire room — creating a consistent, gentle warmth that radiates upward naturally. No cold spots, no draughts, no hot air concentrated at the ceiling.
DGN GAS installs wet underfloor heating systems across London — for new builds, extensions, renovations and retrofits. Several of our customers specifically chose DGN GAS after seeing the quality of our underfloor heating work.
Pipework laid
with precision
Continuous pipe runs set out across the floor on a castellated panel system — set evenly into the panel and pressure‑tested before screeding, so the finished floor heats consistently across every room.
Built around the
right systems
For our low‑temperature, whole‑home underfloor heating projects we work with specialist, high‑quality manufacturers — so every system is designed to run efficiently from the outset.
New builds, extensions
& retrofits
New Build & Extension UFH
The ideal time to install wet underfloor heating is during a new build or extension — before the screed goes down. We work alongside your other trades to ensure installation at the right stage.
Retrofit UFH
Underfloor heating can be retrofitted into existing properties using low-profile systems that sit above the existing floor — minimising height increase. Ideal for renovations and room conversions.
Works with most
floor types
Stone & Tile
The best conductor of heat. Heats up quickly and retains warmth — the most popular choice.
Porcelain
Similar properties to stone. Widely used with wet underfloor heating systems.
Engineered Wood
Specifically designed to work with UFH. Ensure the product is rated for underfloor heating use.
Vinyl & LVT
Modern luxury vinyl tiles work well with underfloor heating. Check manufacturer temperature ratings.
Carpet
Can be used but insulates against heat. Lower tog-rated carpets work best with careful system design.
Solid Wood
Can be used with care and controlled temperature settings. We'll advise on your specific flooring choice.
From survey to
a warm floor
Survey & System Design
