Blackheath lvt — the details that matter
- Subfloor flatness
LVT shows every bump — georgian terraces subfloors in Blackheath 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 Blackheath 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
Bottom line: a UFH floor is only as good as the plank and underlay above it. We spec both for your Blackheath system.

Flooring Over Underfloor Heating in Blackheath — 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 Blackheath 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 Blackheath survey.
