Underfloor Heating Installation
MPM Plumbing & Mechanical Services designs and installs wet underfloor heating systems for commercial and domestic properties across London and the South East, providing an energy-efficient, comfortable, and discreet alternative to conventional radiator heating.
About This Service
Wet underfloor heating works by circulating warm water through a network of pipes laid beneath the floor surface. Heat is distributed evenly and gently across the entire floor area, creating a comfortable warmth from the ground up. Because underfloor heating operates at significantly lower flow temperatures than traditional radiator systems, it is particularly well suited to use with modern condensing boilers, heat pumps, and district heating connections — maximising efficiency and reducing carbon output.
MPM installs underfloor heating in new builds, extensions, refurbishment projects, and commercial fit-outs. We carry out full hydraulic calculations to correctly design the system, install manifolds and zone controls, pressure test before the screed is poured or the floor covering is laid, and commission the completed installation.
Our underfloor heating installations span both commercial and domestic environments — from luxury hotel suites and high-specification apartments to residential extensions and new-build homes, including projects for The Chancery Rosewood Hotel and the Kent & Surrey Nationals Golf Course & Hotel.

Frequently Asked Questions
Wet underfloor heating (also called hydronic underfloor heating) uses a network of small-bore pipes laid beneath the floor surface, through which warm water is circulated from a central heat source — typically a boiler, heat pump, or district heating connection. The warm floor surface radiates heat evenly upward into the room, creating a comfortable, draught-free warmth. Because the entire floor acts as the heat emitter, the system can operate at much lower water temperatures than radiators, making it highly energy-efficient.
Yes, though the approach differs. In new builds and extensions, pipes are typically embedded in a sand-and-cement screed, which provides excellent thermal mass. In retrofit projects where floor build-up must be kept to a minimum, low-profile overlay systems are used — these sit directly on the existing floor and are covered by the new floor finish, keeping the overall height increase to as little as 15–20mm. MPM installs both screed-embedded and overlay UFH systems depending on the project requirements.
Underfloor heating and heat pumps are an ideal combination. Heat pumps operate most efficiently at lower flow temperatures (typically 35–45°C), which is exactly the temperature range at which underfloor heating performs at its best. By contrast, radiators typically need higher temperatures to deliver adequate heat output. Using underfloor heating with a heat pump maximises the system's coefficient of performance (COP), reducing running costs and carbon emissions.
Yes — pre-screed pressure testing is a critical step that MPM carries out on every screed-embedded underfloor heating installation. The system is pressurised and left under test pressure while the screed is poured and cures, confirming there are no leaks in the pipework before it is permanently encased in the floor. A pressure test certificate is provided on completion for the client's records.
MPM installs manifolds with individual circuit isolation and flow adjustment for each heating zone, along with zone valve actuators controlled by room thermostats or a central smart controls system. This allows each room or area to be controlled independently, so rooms can be heated only when occupied and to the temperature required — improving comfort and reducing energy waste.
Yes. MPM has delivered underfloor heating installations in a range of commercial environments, including The Chancery Rosewood Hotel and the Kent & Surrey Nationals Golf Course & Hotel — both of which required high-specification, large-area UFH systems installed to exacting standards within demanding project programmes.
