Fit new flooring over your Erith UFH system
Most Erith 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 Victorian and post-war terraces, plus riverside new-builds along the High Street feet — not the subfloor.

Riverside flats sometimes flag damp — we use a meter before guaranteeing any glue-down vinyl.

Before we quote a lvt job in Erith
- Subfloor flatness
LVT shows every bump — victorian and post-war terraces subfloors in Erith 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 Erith hallways that means front-door to kitchen.
Bottom line: a UFH floor is only as good as the plank and underlay above it. We spec both for your Erith system.

Flooring Over Underfloor Heating in Erith — 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 Erith 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 Erith 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.
