Underfloor heating only works as well as the screed encasing it — and in Branscombe that means a high-thermal-conductivity liquid pour that wraps every pipe with no voids.
The screed self-levels around every loop, eliminating the voids you get under hand-laid traditional screed. That means the floor responds faster when the heating calls for it, and stores less wasted heat.
Most of our Branscombe jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Branscombe sits Exeter (22 mi), and we work the surrounding villages on the same week's diary.

Underfloor Heating Screed in Branscombe — how it works
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Branscombe renovations.
We pour Cemfloor Therm liquid screed over your UFH pipes at 50mm above pipe (typically 65-75mm total over insulation), giving full pipe encapsulation, fast thermal response and a finished surface flat to SR1.
Specifications suited to Branscombe builds
Cemfloor Therm
Liquid screed engineered for UFH — lambda 2.1 W/mK, fast response.
PIR/Phenolic insulation board
70-150mm typical depending on build regs U-value target.
Edge insulation strip
Critical around UFH zones to allow thermal expansion.
Pressure-testing kit
Pipes held at 6 bar through the pour to flag any damage immediately.

Common Branscombe build questions
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
When can I switch the underfloor heating on in Branscombe?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Branscombe clients to the schedule.
Can you pour over a heat-pump system in Branscombe?+
Yes — and we'd argue you should. Heat pumps run at lower flow temperatures than gas, so the screed's thermal conductivity matters more, not less.
Whether it's a single-room retrofit or a full rural self-builders and farms build in Branscombe, the goal is the same — one pour, laser-flat, ready to take coverings without fuss.
