Across Broadclyst we work hand-in-hand with UFH installers — they lay and pressure-test the pipes, we pour around them the next day at the right depth and thermal performance.
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Broadclyst renovations.
Most of our Broadclyst jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Broadclyst sits Exeter (5 mi), and we work the surrounding villages on the same week's diary.
Right fit for Broadclyst rural self-builders and farms
Broadclyst sits rural — barn conversions, self-builds, agricultural sheds, equestrian floors. Access is usually fine, but power and water on site need confirming up front. We do that at the site visit.

Underfloor Heating Screed in Broadclyst — 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.
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.

Broadclyst screed questions, answered
Do you fit the UFH pipes yourself?+
We work alongside your chosen UFH installer rather than fitting pipes ourselves — most Broadclyst jobs come with a heating sub-contractor already lined up, and we coordinate dates with them.
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.
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 Broadclyst?+
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 Broadclyst clients to the schedule.
