Underfloor Heating in Bromley - Warm Floors. No Radiators.
Wet Underfloor Heating • Renovations • New Builds • Heat Pump Integration
Wet underfloor heating distributes warmth evenly across the floor surface, eliminating cold spots and freeing wall space from radiators. For extensions, renovations and new-build projects, a correctly designed system provides comfortable low-temperature heating that works particularly well with heat pumps.

Professional Underfloor Heating Installation in Bromley
Wet underfloor heating, also known as hydronic underfloor heating, circulates warm water through pipes installed beneath the floor. The entire floor surface then acts as a low-temperature radiant emitter, providing consistent warmth throughout the room.
It is best installed during an extension, kitchen or bathroom renovation, or new-build project when the floor is already being opened or constructed. Retrofitting is possible, but usually involves more disruption and additional floor build-up.
Our team designs and installs wet underfloor heating systems for Bromley homes. We coordinate with builders and architects, pressure-test the pipework before the floor is completed, and commission the system for efficient heat pump operation.

How It Works
How Wet Underfloor Heating Works
Four connected stages, from the heat pump to the warmth you feel underfoot.
1
Heat Source
The heat pump supplies warm water at a low flow temperature, typically around 35–45°C, making wet underfloor heating an effective low-temperature emitter.
2
Manifold
A manifold distributes warm water across multiple pipe loops, one per zone or room. Controls water flow rate and temperature to each area independently.
3
Floor Pipes
Cross-linked polyethylene (PEX) pipes laid in a continuous loop beneath the floor , in screed, between battens or within a low-profile overlay system.
4
Radiant Warmth
The floor surface warms to 22–29°C, radiating heat evenly upward. The room reaches a comfortable 20–21°C with no hot/cold zones.
System Design Essentials
What Determines Underfloor Heating Performance?
Wet underfloor heating performance depends on the complete floor and heating system design. These are the main factors we assess before specifying a system.
Insulation & Floor Build-Up
Correct insulation below the pipework directs heat into the room rather than allowing it to escape into the structure. Floor height and build-up are agreed before installation.
Manifold & Zone Design
Pipe loops, flow rates and room zones are designed to deliver balanced heat throughout the property.
Controls & Thermostats
Appropriate thermostats and zone controls allow each area to maintain a stable temperature without unnecessary cycling.
Commissioning & Balancing
The completed system is pressure-tested, flushed, balanced and commissioned so that each loop receives the correct flow.
Floor Type Compatibility
Which Floor Finishes Work With UFH?
The floor finish affects how efficiently heat transfers from the pipes into the room. Dense, conductive materials perform best. Insulating materials require careful system design.
Tiles & Stone
Excellent heat conductor. Best performance. Ideal for kitchens and bathrooms.
Engineered Wood
Good compatibility. Check manufacturer's UFH approval and plank thickness.
Solid Wood
Compatible in most cases. Thicker planks (over 18mm) reduce heat transfer, design accordingly.
Vinyl & LVT
Compatible. Check manufacturer's temperature rating, most modern LVT is UFH-approved.
Carpet
Compatible but reduces efficiency. Total thermal resistance (tog) must be below 2.5. Thin carpet with smooth underlay only.
Laminate
Compatible in most cases. Check manufacturer's UFH suitability, some laminates expand under heat.
- We Assess Your Specific Floor
We review your planned floor finish as part of the survey and design the system to compensate for any additional thermal resistance, ensuring your UFH performs correctly with whatever floor covering you have chosen.
Our Installation Process
How We Install Underfloor Heating in Your Bromley Property
A process built around your renovation or build timeline, not around ours.
1
Site Survey
We visit the property, assess floor construction, planned finish, room heat demand and heat source compatibility. We take measurements and note any specific design considerations.
2
System Design
We calculate heat loss per room, specify pipe diameter and spacing, size the manifold and design the zone configuration. Every UFH system is designed, not templated.
3
Written Quotation
A written quotation covering all materials, labour, manifold installation and commissioning. The figure you receive is the figure on the invoice. No additions.
4
Pipe Installation
Insulation laid, pipes fixed to specification. We coordinate with your builder or screed contractor to ensure the pour happens at the correct stage. Pressure test carried out before screed.
5
Commissioning
Once the floor finish is complete, we return to connect the manifold, balance the system, commission controls and walk you through zone operation. System handed over fully working.
- We work directly with your builder, architect or main contractor to coordinate installation at the correct stage, no delays, no rework. We have supplied documentation required by architects and building control for UFH installations on request.
Planning Ahead
Installing UFH Now Future-Proofs Your Heating for a Heat Pump
The most common regret we hear from Bromley homeowners who have subsequently installed a heat pump is: "I wish I had put underfloor heating in when we did the extension." Retrofitting UFH after the floor is finished is significantly more disruptive and expensive than installing during the original works. If there is any possibility you might consider a heat pump in the next 5–10 years, installing wet UFH now is one of the highest-leverage decisions you can make, it costs far less to do now than as a separate project later, and makes the eventual heat pump installation significantly more effective.
Air Source Heat Pumps in Bromley
Air source heat pumps work particularly well with wet underfloor heating because both systems are designed around low flow temperatures. Qualifying heat pump installations can receive a £7,500 BUS grant. From 21 July 2026, eligible off-gas-grid homes replacing oil or LPG heating can receive £9,000.
Ground Source Heat Pumps in Bromley
Ground source heat pumps also pair effectively with wet underfloor heating, providing consistent low-temperature heat. The same BUS grant levels apply to qualifying ground source installations.
Up to £9,000
BUS grant support applies to the qualifying heat pump installation, not to underfloor heating as a standalone project. The £9,000 rate begins on 21 July 2026 for eligible off-gas-grid oil or LPG replacements.
Why Choose Us
Why Bromley Homeowners Choose Supreme Heating for Underfloor Heating
Installation quality is everything with UFH. A pipe laid without proper pressure testing before the screed goes down is inaccessible for the next 50 years.
MCS Certified Heat Pump Integration
Our MCS certified heat pump experience allows us to design wet underfloor heating around the low flow temperatures required by air source and ground source heat pump systems.
Written Quotation, No Surprises
All UFH installations are quoted in writing before any commitment. The figure covers materials, labour, pressure testing and commissioning. That figure is the invoice. No scope creep, no additions on completion, no verbal estimates that expand mid-project.
Support After Commissioning
After commissioning, we explain the thermostats, zone controls and manifold settings. Ongoing support is available if adjustments or technical guidance are required.
Designed to Your Property, Not Templated
Every wet UFH system we install is designed around a heat loss calculation specific to your property. Pipe spacing, manifold sizing and zone configuration are calculated for your rooms, not copied from the last project. A system designed correctly from the start performs correctly for decades.
Pressure Tested Before Screed, Always
We pressure test the pipe network before any screed is poured or floor covering is installed. A failure identified at this stage is a 5-minute fix. A failure discovered after the screed has cured means breaking up the floor. We do not skip this ste, ever.
Local, We Coordinate With Your Builder
Based in Petts Wood, we attend Bromley renovation sites at the right stage in the build sequence. We work directly with your builder or main contractor, turn up when the floor is ready and complete our stage without causing programme delays.

What Bromley Homeowners Say About Our Renewable Heating Services
Customer feedback from heat pump and heating-system projects across the BR postcode area.
"Alek was professional and punctual, arriving on time and keeping me informed throughout the day. He worked quickly while maintaining high standards of quality and care. The installation was carried out with minimal disruption, and the team made sure to leave the area clean and tidy once the work was completed. What really stood out was the efficiency of the system itself. Since the installation, I've noticed a significant difference in both the warmth of the house and the reduction in my energy bills. The heating system is incredibly effective, and I feel more comfortable in my home, especially during the colder months. I highly recommend Alek and Supreme Heating for anyone looking for a reliable, professional, and efficient heating solution. Their attention to detail and commitment to customer satisfaction were truly impressive."

Trustpilot Review
"When my previous boiler recently broke down during a very cold period of weather Alexander at Supreme heating literally came to the rescue. We were seen on the same day as our first call for an initial consultation, and needing a replacement boiler and water tank (which I knew was imminent) we were then prioritised over less urgent work - this meant that approximately 72 hours from the first call, we had a full replacement system installed. Alexander and everyone at Supreme were a pleasure to work with, they were extremely pleasant, but more importantly advised us expertly and honestly from the very first interaction, keeping us well informed throughout the entire process. The job itself was carried out very efficiently, professionally and with great care taken throughout to minimise the inevitable dirt or disruption to rest of our house during the replacement, with the eventual installation very neat and tidy. I will continue to use Supreme for all of our boiler work and can’t recommend them highly enough."

Questions Answered
Underfloor Heating FAQs, Bromley Homeowners Ask
Direct answers to the questions we are asked most frequently by Bromley homeowners planning UFH installations.
What is wet underfloor heating and how does it work?
Wet underfloor heating circulates warm water through pipes installed beneath the floor. The pipework connects to a heat pump, heating the floor surface so that warmth is distributed evenly throughout the room.
Can underfloor heating work with a heat pump?
Yes. Wet underfloor heating is particularly well suited to heat pumps because both operate effectively at low flow temperatures. We assess heat demand, floor construction, insulation and control requirements before preparing the design.
What floor types are compatible with underfloor heating?
Tiles and natural stone perform best, they conduct heat efficiently and are the most common choice in UFH-heated kitchens and bathrooms. Engineered wood, LVT, vinyl and most laminates are compatible, check manufacturer UFH approval. Carpet can work with a total thermal resistance below 2.5 tog. Solid wood works in most cases, though thicker planks reduce heat transfer. We assess your specific floor finish during the survey and design accordingly.
How long does underfloor heating take to heat a room?
Wet UFH has a longer warm-up time than radiators, typically 30 to 60 minutes to reach operating temperature from cold. For this reason, UFH is best controlled by a programmable or smart thermostat that maintains the floor at temperature throughout the day rather than firing it up from cold. The benefit is even, consistent warmth rather than rapid heat-up followed by cool-down cycles.
How much does underfloor heating cost in Bromley?
Wet UFH installation typically costs between £800 and £1,500 per room for a renovation installation, depending on room size, floor construction and complexity. Whole-property new build installations are priced on a per-square-metre basis. Costs vary significantly by floor type and access, so we provide free written quotations following a property survey rather than estimates over the phone.
Does underfloor heating work with a heat pump?
Yes. Heat pumps are designed to operate efficiently at low flow temperatures, which is also how wet underfloor heating performs best. Installing UFH during a renovation or new build can create an efficient heat distribution system for a current or future heat pump installation.
Can I retrofit underfloor heating to an existing room?
Wet UFH can be retrofitted to an existing room, but it involves lifting the current floor, adding insulation, installing the pipe network and relaying the floor finish. This is significantly more costly and disruptive than installing during a planned renovation when the floor is already being opened. We assess each situation, but the ideal time to install UFH is when other floor works are already planned.
Can underfloor heating replace radiators completely?
Yes. In rooms where wet UFH is installed, radiators are not required. Many Bromley homeowners install UFH in extensions and ground floor renovations while retaining radiators elsewhere, creating a mixed system , the UFH covers the new works, the existing radiators continue to serve the rest of the house. We design whatever configuration suits your property and plans.
