Flooring over underfloor heating in Mottingham
Most Mottingham UFH complaints come from the flooring, not the boiler. A 12mm plank with 3mm foam is doing the wrong job. We use 4–5mm LVT or 8mm UFH-rated laminate over ≤1.0 tog underlay so heat reaches 1920s cottage-estate terraces and post-war infill feet — not the subfloor.

Three things that decide a lvt fit in Mottingham
- Mottingham subfloor reality
Cottage estates often have thin chipboard upstairs — checked for deflection before laying laminate or LVT.
- Pattern direction
Plank run follows the longest sightline; in narrow Mottingham hallways that means front-door to kitchen.
- Door undercut
We trim doors on the day so they swing cleanly over glue-down LVT — no scraping, no callbacks.
- Only UFH-rated LVT, laminate and engineered wood used
- Underlay kept below 1.0 tog so heat actually reaches the room
- Perimeter expansion gap sized for full UFH cycle
- Manifold and probes protected during fit
In short — Mottingham UFH flooring from £38/m² fitted, using UFH-rated planks and low-tog underlay so the heat actually reaches the room.
