Quick Answer
Electric underfloor heating mat systems cost £50-80/m² installed in the UK in 2026. A kitchen of 15m² costs £750-1,200. Wet (water) systems cost £80-150/m² for a screeded floor installation. A whole ground floor wet system for a typical house costs £5,000-9,000. Electric is better for single rooms; wet is better for whole-house or new build installation paired with a heat pump.
What Does Underfloor Heating Cost in the UK?
Underfloor heating has moved well beyond the luxury bracket. In 2026, electric mat systems for a bathroom or kitchen are a routine addition to any tile replacement project, and wet systems for new builds and whole-house retrofits are increasingly specified alongside heat pumps as part of low-carbon heating upgrades.
The cost varies considerably depending on whether you choose electric or wet (water) UFH, the size of the area being heated, whether it is a new installation or a retrofit, and what floor covering will go on top. At the simpler end, adding an electric heating mat under tiles in a bathroom during a renovation costs £300-480 for a 6m² bathroom, which is modest in the context of a wider renovation budget. At the more complex end, a whole ground floor wet system for a 60m² house costs £5,000-9,000 including the manifold, controls, and labour.
This guide covers both electric and wet underfloor heating systems, typical costs by room type and area, running costs, the electric versus wet decision, and how to find a qualified installer. All figures are for 2026 and reflect current UK labour and materials pricing.

Additional Costs to Budget For
The per-m² cost covers the heating element and basic installation. The following are commonly priced separately or not automatically included.
- Thermostat: £50-200 for a standard programmable model; a smart thermostat adds £100-200
- Floor probe sensor: £15-30, required by most electric systems for accurate floor temperature control
- Insulation boards under wet screeded systems: essential to prevent heat loss downward, typically £5-15/m² extra
- Manifold unit for wet systems: £200-600 depending on the number of zones
- Zone controls for multi-room wet systems: £50-150 per zone
- Floor preparation, levelling, or screed repairs if required before installation
What Affects the Cost of Underfloor Heating?
Electric vs wet system choice
Electric UFH is cheaper to install for a single room but more expensive to run long-term. Wet UFH costs more to install because it requires pipework, a manifold, and typically a new or modified screed, but it is significantly cheaper to run, particularly when paired with a heat pump. For a single bathroom, electric is almost always the right choice. For whole-house heating in a new build or major renovation, wet is the better long-term investment.
New build vs retrofit
Installing underfloor heating during construction is significantly cheaper than retrofitting because the floor is open and accessible. During a renovation or retrofit, the existing floor covering and often the screed must be removed before the UFH system can be laid and relaid. This adds considerable labour and materials cost to the project. If you are planning a major renovation, the right time to install UFH is before any new flooring goes down.
Floor type and covering
Tile and stone are the most efficient floor coverings for UFH because they conduct and store heat well. Engineered wood is suitable for UFH if specified as compatible. Thick carpet and dense underlay act as insulators, significantly reducing the efficiency of the system and increasing running costs. If you plan to use carpet over the UFH, discuss this with your installer before specifying the system output: it will need to be sized accordingly and may not be the right choice at all for some carpet types.
Number of zones and controls
A single-room electric UFH system needs one thermostat. A multi-room wet system requires a manifold with individual zone valves and a thermostat per zone. Smart thermostats that allow remote control via an app add £100-200 per unit but can meaningfully reduce running costs by allowing the system to be managed more precisely. The cost of controls and manifold work scales with the number of zones: a 6-zone system adds more to the total than a 2-zone system.
Insulation beneath the system
Installing UFH without adequate insulation beneath it is one of the most common and expensive mistakes. Without insulation, a significant proportion of the heat goes downward into the sub-floor rather than upward into the room. For wet screeded systems, rigid insulation boards should be specified as part of the installation. For electric mats, purpose-made insulation boards or an insulated tile backer board should be used. Under-specifying insulation adds directly to running costs year after year.
Location and installer rates
London and the South East carry a significant premium over the rest of England, reflecting higher plumber and electrician rates. UFH installation involves both trades in many cases: an electrician for the thermostat wiring and element connection, and a plumber or heating engineer for any wet system pipework and manifold. Areas with higher trade day rates therefore see higher UFH installation quotes.
Underfloor Heating Running Costs
Running cost is one of the most important factors in the electric versus wet decision. Electric UFH uses resistance elements to generate heat directly from electricity, which at current rates makes it relatively expensive to run as a primary heating source for large areas. Wet UFH moves heated water through the floor, which is far more efficient and works particularly well with a heat pump at low flow temperatures.
| System | Running Cost | Notes |
|---|---|---|
| Electric UFH | ~£0.15-0.25/hr per m² | Best for single rooms, occasional use |
| Wet UFH (gas boiler) | Comparable to radiators | Marginal efficiency gain over radiators |
| Wet UFH (heat pump) | 60-70% less than electric UFH | Best combination for whole-house heating |
Electric underfloor heating in a bathroom used for 2 hours per morning costs approximately £0.30-0.75 per day at current electricity prices. This is perfectly manageable for a bathroom used as supplementary heat. Running electric UFH across a large living room as primary heat is considerably more expensive and is not recommended without a time-controlled thermostat to avoid the system running unnecessarily.

Electric vs Wet Underfloor Heating: Which Should You Choose?
The choice between electric and wet UFH comes down to the size of the area, the nature of the project, and your long-term heating strategy.
Electric underfloor heating is the right choice for single rooms, particularly bathrooms, kitchens, and extensions where you want supplementary warmth under tiles. It is straightforward to install during any tile replacement project, costs less upfront, and can be controlled independently of the rest of the heating system. The running costs are higher per unit of heat, but for a bathroom used for a few hours a day, this is rarely a significant concern.
Wet underfloor heating is the right choice for whole-house installations, new builds, and any project where the floors are being opened up anyway. It has lower running costs, particularly when paired with a heat pump, and is better suited to being the primary heating system for an entire floor. The higher installation cost is justified by the long-term running cost saving and the comfort of uniform radiant heat across the whole ground floor.
If you are already planning a heat pump installation, wet UFH is almost always the recommended partner technology because heat pumps work most efficiently at the low flow temperatures that UFH requires, typically 35-45 degrees Celsius, compared with the 60-80 degrees needed by standard radiators. For more on heat pump costs, see the heat pump installation cost guide.
How to Find a Reliable Underfloor Heating Installer
Underfloor heating installation typically involves both an electrician (for electric systems and thermostat wiring) and a plumber or heating engineer (for wet systems). For a bathroom electric mat system installed during a tiling project, the tiler may handle the mat laying while the electrician connects the thermostat and element.
- For electric UFH: ensure the electrician is Part P registered or uses a registered electrician for the final connection. The installation must be notified to building control
- For wet UFH: the plumbing and manifold work should be carried out by a qualified heating engineer, and any boiler connections must be done by a Gas Safe registered engineer
- Ask for a written specification detailing the brand, system type, output per m², insulation specification, and thermostat included in the quote
- Check that the quote includes insulation, not just the heating element: under-insulated UFH is an expensive mistake to correct retrospectively
- Get at least two or three quotes and compare them on like-for-like specifications

Frequently Asked Questions
How much does electric underfloor heating cost per m² in the UK?
Electric heating mat systems cost £50-80/m² installed in 2026. Loose cable systems cost £40-70/m². Retrofit systems that fit under existing floors without lifting tiles cost £60-100/m². These figures include the heating element and standard installation, but not the thermostat or floor preparation.
Which is cheaper to run: electric or wet underfloor heating?
Wet underfloor heating is significantly cheaper to run, particularly when paired with a heat pump. Electric UFH uses direct resistance heating and costs approximately £0.15-0.25 per hour per m² at current electricity prices. Wet UFH run from a heat pump can deliver the same heat output at 60-70% lower running cost per unit of heat. For a bathroom or kitchen supplement, electric is fine. For whole-house primary heating, wet is the better long-term choice.
What floor types work with underfloor heating?
Ceramic and porcelain tile is the best floor covering for UFH: it conducts and retains heat well. Stone works similarly. Engineered wood is suitable if specifically rated for use over UFH. Solid hardwood is generally not recommended because it expands and contracts too much. Thick carpet and underlay insulate against the heat and significantly reduce the efficiency of any UFH system.
Can underfloor heating be installed under existing floors?
Yes, but the approach depends on the existing floor type. Electric mat systems can be laid directly in tile adhesive under new tiles without any floor lifting, making them ideal for bathroom or kitchen retrofits where the tiles are being replaced anyway. Low-profile wet systems designed for retrofit can be installed under a floating floor with minimal height addition. Full wet screeded systems require the existing floor to be excavated and a new screed laid, making them most cost-effective in a new build or complete renovation.
How long does underfloor heating last?
Electric underfloor heating systems have very few moving parts and can last 25 years or more if correctly installed and not damaged during any subsequent floor work. Wet pipe systems, if installed using quality cross-linked polyethylene (PEX) pipe, have design lifespans of 50 years or more. The thermostat and controls are the components most likely to need replacing, typically after 10-15 years.
Does underfloor heating add value to a house?
A whole-house wet underfloor heating system, particularly one paired with a heat pump, is increasingly valued by buyers looking at energy efficiency. Bathroom and kitchen electric UFH is seen as a quality finish detail. Neither adds a directly measurable percentage to house value, but they contribute to overall presentation and the sense that the property has been well maintained and upgraded. For a sale-ready property, working UFH in the bathrooms is a small detail that buyers notice.
