UFH GUIDE · ESHER
Solid wood flooring over underfloor heating in Esher
UFH and wood flooring is where most Esher installs go wrong, because the rules differ from manufacturer to manufacturer and the consequences (cupping, gapping, delamination) only show up months later. Esher clients often want glue-down 600mm herringbone in 22mm engineered oak — premium spec, real attention to subfloor flatness. This page covers exactly how we fit solid wood flooring over UFH for Esher homes — temperature ramps, underlay tog, and which products are actually rated for the heat output you've got.
What matters for solid wood flooring in Esher
- Maximum surface temperature for any wood floor is 27°C — Esher new-build manifolds often run hotter and need a thermostat cap.
- Underlay tog should sit under 0.5 — anything thicker insulates the heat back into the screed instead of the room.
- Screed must read below 1.8% CM moisture before any wood goes down. We bring our own meter to every Esher survey.
- A 14-day temperature ramp (start cold, +5°C per day) protects the boards and the joints during commissioning.
- Solid oak moves with humidity, so subfloor prep, moisture testing and acclimatisation are critical — especially in older properties.
Typical Esher use cases
Wet UFH on screed in Esher
Default spec: 14–15mm engineered oak, glue-down, low-tog underlay or fully bonded.
Electric UFH retrofit
Lower output — most solid wood specs are still safe, but we check the wattage per m² before quoting.
Esher kitchen extension
UFH in the new section, joist construction in the old — we plan an expansion break at the transition.

Esher FAQs
- Can I fit solid wood over UFH in Esher?
- We don't recommend it. Solid moves too much with temperature swing — engineered oak gives you the same look with proper stability.
- What's the right underlay for UFH in a Esher flat?
- Something under 0.5 tog, ideally a fully bonded adhesive. We use Sika Bond or F. Ball depending on the screed.
- How long after the UFH is commissioned can you fit?
- Minimum 14 days after final screed temperature, with documented moisture readings under 1.8% CM.
- Do you cover Esher for UFH installs?
- Yes — and the surrounding Cobham, Claygate, Oxshott area. UFH installs are one of our most common Esher jobs.
Summary
Solid wood over UFH in Esher is fine — but only with the right spec, the right underlay, and the right ramp. We do all three in writing before fitting.
