UFH GUIDE · BRIGHTON
Solid wood flooring over underfloor heating in Brighton
UFH and wood flooring is where most Brighton installs go wrong, because the rules differ from manufacturer to manufacturer and the consequences (cupping, gapping, delamination) only show up months later. Brighton's Regency homes are full of moisture-heavy lower-ground rooms — DPM membranes and moisture-testing aren't optional, they're routine. This page covers exactly how we fit solid wood flooring over UFH for Brighton 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 Brighton
- Maximum surface temperature for any wood floor is 27°C — Brighton 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 Brighton 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 Brighton use cases
Wet UFH on screed in Brighton
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.
Brighton kitchen extension
UFH in the new section, joist construction in the old — we plan an expansion break at the transition.

Brighton FAQs
- Can I fit solid wood over UFH in Brighton?
- 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 Brighton 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 Brighton for UFH installs?
- Yes — and the surrounding Hove, Kemptown, Preston Park area. UFH installs are one of our most common Brighton jobs.
Summary
Solid wood over UFH in Brighton is fine — but only with the right spec, the right underlay, and the right ramp. We do all three in writing before fitting.
