Restoration flooring over underfloor heating in Farnham
UFH and wood flooring is where most Farnham installs go wrong, because the rules differ from manufacturer to manufacturer and the consequences (cupping, gapping, delamination) only show up months later. Farnham's listed Georgian properties usually need breathable finishes and reversible fits — typically secret-nailed solid oak over battens. This page covers exactly how we fit floor restoration over UFH for Farnham homes — temperature ramps, underlay tog, and which products are actually rated for the heat output you've got.
What matters for floor restoration in Farnham
- Maximum surface temperature for any wood floor is 27°C — Farnham 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 Farnham survey.
- A 14-day temperature ramp (start cold, +5°C per day) protects the boards and the joints during commissioning.
- We dust-extract sand on site so you can stay in the property; gaps are filled with resin-and-sawdust slurry matched to the boards before staining.
Typical Farnham use cases
Wet UFH on screed in Farnham
Default spec: 14–15mm engineered oak, glue-down, low-tog underlay or fully bonded.
Electric UFH retrofit
Lower output — most restoration specs are still safe, but we check the wattage per m² before quoting.
Farnham kitchen extension
UFH in the new section, joist construction in the old — we plan an expansion break at the transition.

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