What is beneath the finish?
We establish whether the floor is solid, screeded, suspended timber, retained boards or a combination—and whether insulation and access are adequate.

Underfloor Heating Installation in Hampstead, NW3
Historic floors. Modern heating. One system designed around the building.
PEP designs, supplies and installs complete wet and electric underfloor heating systems for Hampstead homes. From low-profile Wunda retrofits and suspended timber floors to new screeded extensions, we resolve the floor levels, insulation, heat loss, plant space, finish and controls before installation begins.

Designed for the building
One Hampstead home can require more than one floor-heating answer.
A single refurbishment may combine an original suspended timber reception floor, a solid lower-ground level, a newly insulated screed extension and tiled bathrooms. Treating every room as if it had the same construction creates avoidable compromises.
PEP surveys what is beneath each area, reviews room heat loss and works backwards from the intended floor finish. The system can then change by floor while the heating strategy remains coordinated across the property.
That early design protects thresholds, stairs, skirtings, retained joinery, fireplaces, bathroom falls and the junctions between original and rebuilt floors.

Survey before specification
The floor is inspected before the heating system is selected.
The right answer depends on measured conditions, not the name printed on a product box.
Can the active floor meet the heat loss?
Room demand, usable heated area, pipe spacing and operating temperatures are reviewed before underfloor heating is treated as the primary emitter.
Where will every millimetre go?
Door clearances, stairs, skirtings, kitchen plinths, acoustic layers, adhesives and finished-floor transitions are included in the build-up.
How will the rooms be supplied and controlled?
Manifold location, pipe routes, boiler or heat-pump compatibility, existing radiators, power supplies, thermostats and access are coordinated together.
Four constructions, four answers
Match the underfloor heating method to the floor.
The selected system must deliver the required output without sacrificing retained structure, finished levels or future service access.
01 · Retained solid floors
Low-profile overfloor heating
Where the structural floor is sound, a low-profile water-based system can provide a responsive retrofit route without excavating the complete floor. Preparation, panel, decoupling, adhesive and finish are included in the level calculation.
02 · New and rebuilt floors
Screed underfloor heating
For extensions, basements and full floor replacements, pipework can be fixed over insulation before the screed is laid. Insulation, spacing, movement details and screed specification are coordinated as one assembly.
03 · Suspended timber floors
Joisted underfloor heating
Joist direction, supported heat spreaders, pipe turns, insulation below the plates, retained boards and future access are resolved before the original floor is closed.
04 · Selected rooms
Electric underfloor heating
Electric mats or loose cable can suit bathrooms, en suites and compact tiled spaces. Fixed furniture, wet areas, floor sensor, thermostat, electrical protection and test stages are mapped before the finish is laid.
Specified as a complete system
A complete Wunda system—designed before it is ordered.
PEP works with Wunda Group to provide correctly matched underfloor heating packages at highly competitive project prices. The panel or pipe is only one component of a complete installation.
Circuit lengths, spacing, manifold position, actuators, wiring centres, thermostats, pumps, blending controls, sensors and heat-source connections are coordinated before materials arrive.
We review the plans and floor constructions first, so the installation team receives the correct components and one coordinated basis for fitting, testing and commissioning.

The working centre of the system
The manifold must be accessible, serviceable and correctly connected.
The manifold needs efficient routes to every circuit and permanent access after the refurbishment. Its position should be coordinated with joinery, room layouts and the route back to the heating plant—not discovered after pipework is installed.
Where radiators and underfloor heating share a property, their different operating temperatures and response times must be addressed in the hydraulic arrangement and control strategy.

Finished floor and final proof
Floor finishes are part of the heating design—not decoration added later.
Tile and stone transfer heat efficiently, while engineered timber, LVT, laminate, carpet and underlay each impose their own thermal and temperature limits. Product approval, adhesive, moisture, curing, levelling, decoupling and expansion details all belong in the design.
Water circuits are filled, vented and pressure-tested before concealment. At commissioning, circuits are balanced, control sequences are proved and the completed floor response is checked before handover.

From first review to warm floor
One coordinated route through eight project stages.
Each layer is reviewed before it closes the next one in, from structural floor and insulation to pipework, controls and the final finish.
Initial review
Postcode, plans, rooms, proposed finishes and project stage.
Site survey
Floor build-ups, heat source, routes, access and electrical provision.
Heat design
Room demand, active floor area, temperatures and zones.
Coordinated quote
Defined systems, preparation, components, controls and interfaces.
Preparation
Substrate, insulation, levels and retained-building protection.
Installation
Pipework or cable, manifold, actuators, thermostats and wiring.
Testing
Pressure or electrical tests before the floor is completed.
Commissioning
Balancing, functional proof, operating information and handover.
Wet or electric?
Select by area, duty and construction—not habit.
A heat-loss assessment establishes whether the usable heated floor can meet the room requirement and whether another emitter is needed.
Water-based
Principal rooms and larger areas
Usually the stronger option for living areas, whole floors, extensions and multi-zone systems integrated with a boiler or heat pump.
Electric
Selected compact rooms
Practical for isolated bathrooms, en suites and tiled spaces where extending a water-based system would add disproportionate disruption.
Combined
Different systems, one control plan
Wet heating in the principal rooms and electric floor warming in selected bathrooms can work together when each has a clearly defined duty.
One accountable team
Heating, plumbing and electrical controls belong to one project.
An underfloor heating installation crosses several trade boundaries. The heating design affects the floor build-up. The manifold needs plumbing routes and joinery space. Thermostats, actuators and wiring centres require electrical planning. The boiler or heat pump must respond correctly to zone demand.
PEP brings those interfaces into one scope. Heating and Gas Safe work, fixed electrical work through our NICEIC discipline, plumbing, controls, testing and commissioning follow one coordinated programme.
With London experience since 2010, we understand that successful work in Hampstead depends as much on preparation, sequencing and protection of the property as on the components hidden below the floor.
Local Hampstead coverage

We cover Hampstead and nearby areas where they form part of the same project or practical service route.
Before work begins
Useful answers for a Hampstead UFH project.
Floor construction, heat loss, final finish and the wider building usually determine the most sensible route.
Can underfloor heating be retrofitted without removing the entire floor?
Often, yes. Low-profile systems can be installed over a sound retained floor, subject to preparation, available height, heat loss and the chosen finish.
Can underfloor heating be installed beneath original Hampstead floorboards?
Potentially. The joist layout, board condition, insulation, access and any conservation constraints need to be reviewed before the installation method is selected.
How much height does a low-profile system add?
The panel is only one part of the finished build-up. Preparation, levelling, decoupling, adhesive and the floor covering must all be included in the final level calculation.
Is underfloor heating suitable for a new extension?
Yes. A new screeded floor provides an excellent opportunity to coordinate insulation, pipe spacing, screed depth and finished levels from the beginning.
Can underfloor heating work alongside radiators?
Yes. Mixed systems are common in multi-storey refurbishments, but radiator and floor circuits require suitable temperatures, hydraulic design, zoning and controls.
Can underfloor heating use my existing boiler?
Sometimes. We review the existing boiler, calculated demand, system arrangement, temperatures and controls before confirming compatibility.
Can a Hampstead UFH system work with a heat pump?
Yes, where the property heat loss, available active floor area and design temperatures support the intended heat-pump operation.
Which floor finishes work with underfloor heating?
Tile, stone, engineered timber, LVT, laminate and suitable carpet systems can work. Each product’s thermal resistance, temperature limit and installation instructions must be respected.
Does a listed Hampstead property need consent?
There is no universal answer. Alterations to protected flooring, structure or other historic fabric may require Listed Building Consent or another approval, which should be confirmed by the appropriate project adviser or authority.
How long does installation take?
The programme depends on preparation, heated area, floor construction, number of zones and coordination with screeding, joinery, tiling or other trades. We programme the work for the agreed project scope.
How is the system tested before the floor is covered?
Water circuits are filled, vented and pressure-tested before concealment. Electric systems are tested at the required installation stages. Controls and hydraulic performance are proved during commissioning.
How much does underfloor heating installation in Hampstead cost?
Price depends on heated area, floor construction, preparation, number of zones, controls and heat-source integration. PEP provides a project-specific quotation for the agreed scope rather than an unreliable flat rate per square metre.
