Flooring over underfloor heating in Thamesmead
Most Thamesmead 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 1970s Peabody-era estates transitioning to mid-rise new-builds feet — not the subfloor.
What flooring over underfloor heating in Thamesmead actually involves
Most Thamesmead 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 1970s Peabody-era estates transitioning to mid-rise new-builds feet — not the subfloor.
Original 70s screed is often uneven — self-levelling latex is almost always needed for LVT.
Thamesmead lvt — the details that matter
- Subfloor flatness
LVT shows every bump — 1970s peabody estates subfloors in Thamesmead almost always need ply or self-levelling screed first.
- Door undercut
We trim doors on the day so they swing cleanly over glue-down LVT — no scraping, no callbacks.
- Pattern direction
Plank run follows the longest sightline; in narrow Thamesmead hallways that means front-door to kitchen.
- 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 — Thamesmead UFH flooring from £38/m² fitted, using UFH-rated planks and low-tog underlay so the heat actually reaches the room.

Flooring Over Underfloor Heating in Thamesmead — common questions
Yes — but only UFH-rated boards (usually 8mm HDF core, marked on the pack) with an underlay under 1.0 tog. Standard 12mm click laminate will insulate your UFH and cost you heat.
For heat transfer, yes — 4–5mm LVT sits directly on the screed with a very low thermal resistance. Most new Thamesmead kitchens over UFH now go LVT for that reason.
55°C at the plank, 27°C at the floor surface — the industry standard. Above that, planks cup and joints open. We commission with your plumber so we know the ramp-up.
Yes — dropped to 15–18°C for 48 hours before, off during the fit, then ramped back up 2°C per day. We give you the schedule in writing after the Thamesmead survey.
