Underfloor heating only works as well as the screed encasing it — and in Shepton Mallet 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 Shepton Mallet jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Shepton Mallet sits Bridgwater (20 mi), and we work the surrounding villages on the same week's diary.

Underfloor Heating Screed in Shepton Mallet — how it works
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.

What backs our Shepton Mallet work
Shepton Mallet screed questions, answered
Can you screed over wet UFH and electric UFH?+
Yes — Cemfloor Therm encapsulates both. Electric mat systems usually take a thinner cover; wet pipes need the 50mm minimum.
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.
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.
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.
When can I switch the underfloor heating on in Shepton Mallet?+
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 Shepton Mallet clients to the schedule.
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.
