Flooring over underfloor heating in Lee
Underfloor heating only works if the floor above it is spec'd correctly. Wrong underlay, wrong plank thickness or a sealed perimeter and the room stays cold. In Lee we fit LVT, laminate and engineered wood rated for UFH, on underlay under 1.0 tog, with a proper expansion gap so the boards can move through the heating cycle.

Victorian terraces often have suspended timber over ventilated voids — careful nailing only.
- 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
Before we quote a lvt job in Lee
- Subfloor flatness
LVT shows every bump — victorian terraces subfloors in Lee 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 Lee hallways that means front-door to kitchen.

Flooring Over Underfloor Heating in Lee — common questions
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 Lee survey.
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.
For heat transfer, yes — 4–5mm LVT sits directly on the screed with a very low thermal resistance. Most new Lee kitchens over UFH now go LVT for that reason.
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.
