Underfloor heating creates an even spread of warmth across the room, removing the need for traditional radiators and helping free up valuable wall space.
Keystone London designs and installs underfloor heating systems across West, South West and Central London for renovations, extensions, new layouts and whole-property heating upgrades.
We assess your floor construction, heat requirements, zoning, controls and existing heating system before designing a layout that suits the property and the way each space will be used.

Compatible controls can allow convenient temperature management.
System layouts can be designed around different floor constructions.
Pipe layouts, flow rates, manifolds and controls are considered together.
If underfloor heating forms part of a larger renovation or new heating system, our heating design & installation service can help coordinate the wider system.
Good underfloor heating starts with the design. Pipe spacing, heat output, floor construction, zoning and controls all need to work together so each room heats evenly and the system operates efficiently.
Underfloor heating should not be treated as a simple pipe layout. Different rooms can have different heat losses, floor finishes and temperature requirements, so the system needs to be designed around the property as a whole.
We can work from architectural drawings or assess the property on site where required, then specify the pipework, manifold position, controls and zoning needed for the installation.
Send us your drawings and any information you have about the floor construction, boiler or heat source and proposed room layouts.
We consider the size and use of each space so the system can provide an appropriate level of heat.
Solid floors, suspended floors and renovation build-ups can require different installation methods and pipe layouts.
Pipe routes and spacing are planned to help distribute heat evenly across the usable floor area.
We identify a practical location for the manifold while considering pipe routes, accessibility and the wider heating system.
Rooms or areas can be divided into zones so temperatures can be controlled independently where appropriate.
Thermostat locations and control strategy are planned alongside the zones to make the system practical to operate.
We consider how the underfloor heating will connect to the wider system, including flow temperatures, controls and the manifold arrangement. If the project also includes a new boiler, both parts can be planned together.
Underfloor heating can work with many common floor finishes, but the flooring material, construction and overall build-up all affect how efficiently heat moves into the room.
Some materials transfer heat more easily than others. Tiles and stone generally respond quickly, while timber, engineered wood and carpet require more consideration around temperatures, thickness and thermal resistance.
We take the intended floor finish into account during the system design so the pipe layout, controls and operating temperatures can be planned appropriately.
Let us know during the design stage if different rooms will use different floor finishes so this can be considered from the start.
Tile and stone conduct heat effectively and are commonly used with underfloor heating in kitchens, bathrooms and open-plan spaces.
Many engineered wood products can be suitable when installed and operated within the flooring manufacturer’s temperature limits.
Solid timber requires careful consideration because natural wood can respond to changes in heat and moisture.
Carpet can be compatible where the combined thermal resistance of the carpet and underlay remains suitable for the heating system.
Ideal where wall space is valuable and large floor areas are available.
Comfortable floor temperatures with commonly used tile finishes.
Even heat distribution across larger living and dining areas.
A practical option when the floor construction is already being rebuilt.
Underfloor heating is not limited to new builds. With the right design, it can also work well in extensions, refurbishments and existing homes where floor levels, insulation and construction are carefully considered.
Retrofit projects often need more detailed planning because floor height, existing finishes, insulation levels and access can all affect the installation method.
We look at the current floor build-up and how much change is practical, then design the system around the property rather than forcing a standard layout.
Underfloor heating is often easiest to integrate while floors, kitchens or room layouts are already being changed.
New floor construction creates a good opportunity to design the heating around insulation, screed depth and the final floor finish.
Underfloor heating can free up wall space and works well where kitchens are being reconfigured or opened into larger living areas.
Bathrooms are a common retrofit location, especially where tile floors are being replaced and the floor build-up is already changing.
Larger renovation projects can use underfloor heating across several rooms or an entire floor with individual zones and controls.
How much build-up can be added without creating awkward level changes.
Heat should be directed into the room rather than lost into the structure below.
Solid and suspended floors can require different retrofit approaches.
The finished surface affects heat transfer and system temperatures.
Underfloor heating can be divided into separate zones so different rooms or areas can be controlled independently. Good zoning and control design helps improve comfort and prevents unnecessary heating in spaces that are not being used.
Different rooms, floors or living areas can operate as separate zones, allowing each space to follow its own temperature requirements.
Useful for bedrooms, living spaces and areas used at different times.
Thermostats allow individual zones to call for heat when required and help maintain a more consistent room temperature.
Thermostat positioning is considered during the system design.
Compatible systems can allow schedules, temperature changes and zone management to be controlled from a smartphone or connected thermostat.
Useful for properties where heating schedules change throughout the week.
Each circuit needs the appropriate flow through the manifold so heat is distributed correctly across the different zones.
Correct setup helps avoid rooms heating unevenly.
Underfloor heating can operate effectively at lower water temperatures than many traditional radiator systems, but overall efficiency depends on the complete installation.
Insulation, floor build-up, heat loss, controls, system temperatures and the heat source all influence how efficiently the property heats.
Appropriate insulation below the heating system
Correctly designed pipe spacing and circuit lengths
Suitable flow and return temperatures
Independent zoning where practical
Correct commissioning and manifold balancing
A successful underfloor heating installation depends on good preparation, accurate pipework and correct commissioning. We keep the process clear from the first design stage through to final testing and handover.
We review the property, floor construction, room layout, heating demand and proposed zones before designing the underfloor heating system.
The installation area is prepared for the chosen system, with insulation, zones and manifold routes considered before the heating pipework is laid.
Pipework is installed to the designed layout and connected to the manifold, with each circuit arranged for the relevant heating zone.
The installed pipework is pressure-tested before the floor is completed so the system can be checked for integrity before it is covered.
Once the system is ready, the manifold and controls are set up, zones are checked and we explain how to operate the heating system.
This helps confirm the integrity of the underfloor heating circuits before screed, boards or the final floor finish are installed.
Underfloor heating works best when the design, installation and controls are considered together. Our approach focuses on accurate planning, careful installation and clear communication from the first survey through to final handover.
We design each system around the property layout, floor construction, heat requirements, zones and intended controls.
Our engineers understand how underfloor heating integrates with the wider heating system, manifolds, controls and heat source.
We can design systems for different floor constructions, including renovation projects where available floor height is limited.
Pipework is tested before the floor is completed so the integrity of the installed heating circuits can be checked.
We plan heating zones and thermostat control around how different rooms and areas of the property will actually be used.
From initial plans and specifications to commissioning and final controls, we keep the installation process clear and organised.
Answers to common questions about underfloor heating installation, flooring compatibility, zoning, efficiency and retrofit projects.
Underfloor heating distributes heat across the floor surface rather than relying on wall-mounted radiators. In a wet system, heated water flows through pipework installed beneath the floor and gradually transfers heat into the room above.
Yes, in many cases. Retrofit installations need careful consideration of available floor height, insulation, existing floor construction and the final floor finish before the most suitable installation method can be recommended.
In a correctly designed system, underfloor heating may be able to provide the required room heat without traditional radiators. The heat requirement of each room should be assessed before deciding whether underfloor heating can act as the main heat source.
Many common finishes can be suitable, including tile, stone, engineered wood and some carpet systems. Material thickness, underlay and manufacturer guidance all affect how efficiently heat can pass through the finished floor.
A well-designed system can operate effectively at relatively low water temperatures. Overall efficiency also depends on insulation, heat loss, floor construction, zoning, controls and the wider heating system.
Warm-up time varies depending on floor construction, insulation, screed depth, operating temperature and floor finish. Heavier floor build-ups generally respond more gradually than lightweight systems.
Yes. Underfloor heating can be divided into separate zones, allowing different rooms or areas to use independent thermostats and heating schedules where the system has been designed accordingly.
Yes. Wet underfloor heating can be connected to a suitable boiler system through the correct manifold, controls and temperature arrangement. The wider heating system should be considered during the design stage.
Underfloor heating can work well with suitable low-temperature heat sources, including heat pumps. The design still needs to account for heat loss, required output, floor construction and flow temperatures.
Wet underfloor heating systems generally require relatively little day-to-day maintenance, but manifolds, controls, pumps and the wider heating system may still need periodic checks or adjustment.
