Milled Underfloor Heating Specialists
Milled (or “in-cut”) underfloor heating cuts channels directly into your existing concrete or screed floor for the pipe — no new screed poured, no raised floor levels. Compare verified UK specialists who install it.
What Is Milled (In-Cut) Underfloor Heating?
Most underfloor heating retrofits either pour a new screed layer over the pipe or fit low-profile overlay boards on top of the existing floor — both raise the finished floor level, adding several of the layers shown on the right. Milled underfloor heating takes a different approach: a specialist milling machine cuts channels directly into your existing concrete slab or screed, the pipe is laid into those channels, and the surface is reinstated with a thin latex compound. The floor stays at the same height it was before.
It's primarily a retrofit technique — suited to renovations and extensions on existing concrete or screeded floors, especially where raising the floor level isn't practical because of doorways, staircases, low ceilings or a listed building.
A standard layered build-up, shown for comparison — milled UFH skips most of these layers by cutting straight into the floor you already have.
Why Choose a Milled Retrofit
No new screed, no raised floor levels
Channels are milled directly into your existing screed or concrete slab, so the pipe sits in the floor you already have — doors, skirting and staircases stay untouched.
Dust-extracted, low-mess installation
Specialist milling machines run with industrial dust extraction, so the process is far less disruptive than a full screed-up retrofit.
No doors or skirting to trim
Because the floor level doesn’t change, there’s none of the door-planing, skirting and threshold work a raised-floor retrofit usually needs.
Faster than an overlay-board retrofit
Milling, laying pipe and reinstating the surface is typically quicker room-by-room than fitting overlay boards or pouring a new screed.
How Floor Milling for Underfloor Heating Works
Mark out pipe routes
The installer maps the heating loop across the room, working around fixed fittings and the existing floor build-up.
Mill channels into the floor
A specialist milling machine cuts precise channels into the existing screed or concrete along the marked routes.
Lay and pressure test the pipe
Pipe (typically 16mm multilayer PERT with an oxygen barrier) is laid into the channels, then the loop is pressure tested before it’s covered.
Reinstate the floor
A cementitious latex compound is applied over the pipe to protect it and level the surface, ready for your chosen floor finish.
