Professional Underfloor Heating Installation in Bromley
Wet underfloor heating — sometimes called hydronic underfloor heating, circulates warm water through a network of pipes beneath your floor, turning the entire floor surface into a low-temperature radiant heater. The result is even warmth from the ground up, no cold corners, no radiators on walls and a room that feels consistently comfortable rather than warm near the radiator and cold everywhere else.
It is the right choice at the right moment, during an extension, a kitchen or bathroom renovation, or a new build, when the floor is already being opened or laid. Retrofitting into an existing room without other works is rarely practical for wet systems. The best time to install underfloor heating is when the floor is already up.
Our Gas Safe registered engineers design and install wet UFH systems for Bromley homeowners across extensions, renovations and new builds. We coordinate with builders and architects, commission the system correctly once the floor is complete, and connect it to your existing boiler or new heat pump.
Radiators & System Upgrades
Radiator Replacements and Heating Upgrades
A full boiler replacement is not always the answer. Strategic upgrades to radiators, controls and system components often deliver significant improvements in comfort and efficiency without the cost of a complete system replacement. We assess which components are actually limiting your system's performance before recommending any work.
- What we install
Wet (Hydronic) Underfloor Heating
- Warm water pipes beneath the floor, connected to your boiler or heat pump
- Lower running costs, cheaper per kWh than electric
- Ideal for whole-room or whole-property heating
- Works at low flow temperatures (35–45°C), optimal for heat pumps
- Adds value, considered a premium installation by buyers
- Longer lifespan, pipe networks typically last 50+ years
- electric uFH
Dry Underfloor Heating
- Electric heating mats or cables, no connection to boiler or heat pump
- Higher running costs, electricity is more expensive per kWh than gas
- Better suited to small supplementary areas, bathrooms, single rooms
- Quicker to heat but expensive to run continuously
- Simpler to retrofit, no pipework required
- Not appropriate as a primary heating source for large spaces
- For extensions, kitchen renovations, new builds or whole-property heating in Bromley, wet underfloor heating is almost always the right choice. For a single bathroom without other renovation works, electric may be simpler. We advise honestly on which suits your specific situation.
How It Works
How Wet Underfloor Heating Works
Four connected stages, from your boiler or heat pump to the warmth you feel underfoot.
1
Heat Source
Your boiler or heat pump heats water to a low flow temperature of 35–45°C, lower than the 70–80°C required for radiators.
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.
Compatibility & Suitability
Is Wet Underfloor Heating Suitable for My Bromley Property?
Most Bromley properties undergoing renovation or extension work are suitable for wet UFH. The main variables are floor construction and heat source. Here is what determines suitability.
Radiator Replacement
An undersized or corroded radiator limits the whole room. We calculate the correct output for each room and replace like-for-like or upgrade where the original was incorrectly specified.
System Balancing
Uneven heat distribution across a property is almost always a balancing issue, not a boiler fault. Properly balanced radiators deliver even heat throughout without the boiler working harder.
Smart Thermostat Installation
Nest, Hive and Drayton Wiser thermostats reduce heating energy use by 15–25% on average, not through reducing comfort, but through stopping the boiler running when the house is empty or already warm enough.
Power Flushing
Sludge accumulation in heating pipework reduces radiator output and forces the boiler to work harder. A power flush clears blockages and restores system performance, extending boiler lifespan and improving efficiency.
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.

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.
Gas Safe + MCS Certified, Boiler or Heat Pump
As both Gas Safe registered heating engineers and MCS certified heat pump installers, we design UFH systems that work correctly with whatever heat source you have now, and will connect seamlessly to a heat pump when you are ready to transition.
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.
20+ Years, We Are Here After Commission Too
A wet UFH system, installed correctly, should need almost no maintenance for decades. But if you ever have a question about zone controls, manifold settings or flow rates after handover, we answer. We have been in Bromley for over 20 years. We are not going anywhere.
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.

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 (hydronic UFH) circulates warm water through pipes installed beneath the floor. The pipes connect to your boiler or heat pump, heating the entire floor surface, which then radiates warmth evenly upward into the room. Unlike radiators which create convection currents and uneven heat, UFH delivers consistent warmth from the ground up at a lower, more comfortable temperature.
Can underfloor heating work with my existing boiler?
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, and this is one of the strongest reasons to install wet UFH during a renovation. Heat pumps are designed to produce heat at low flow temperatures (35–45°C), which is precisely what UFH requires. This combination produces a system efficiency well above what is achievable with radiators and a heat pump together. Installing UFH now prepares your property for a heat pump transition whenever you are ready.
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.
