Ask anyone working in the heating trade what has changed most in the past decade, and the answer comes back with striking consistency. Underfloor heating has moved from a premium upgrade to a default specification. Radiator Outlet, a specialist supplier with years of experience across the new-build market, has watched that shift happen in real time, and its account of the change is worth hearing because it comes from the trade rather than the brochure.
The reasons behind the shift are not mysterious. They are regulatory, technical, and commercial, and they explain why a buyer walking into a new-build home today is increasingly likely to find warm floors rather than wall-mounted radiators.
The Regulatory Push
Building regulations have tightened considerably, and energy performance is now central to how new homes are designed and approved.
Modern standards demand high levels of insulation, airtight construction, and efficient heating systems. Electric underfloor heating fits this framework better than radiators. It distributes heat evenly at low flow temperatures, which pairs naturally with condensing boilers and heat pumps, and it avoids the heat loss associated with radiators positioned against external walls.
The Future Homes Standard has accelerated the trend. As gas boilers are phased out in favour of heat pumps, the heating systems specified in new builds must be able to run efficiently at lower temperatures. Underfloor heating does exactly that, which is why it has become the practical choice rather than a discretionary one.
The Heat Pump Partnership
Heat pumps operate most efficiently at flow temperatures of around 35°C to 45°C. Traditional radiators sized for a gas boiler struggle to deliver adequate warmth at those temperatures without being significantly enlarged.
Underfloor heating, with its large surface area, delivers comfortable heat at precisely the temperatures a heat pump prefers. Radiator Outlet notes that this pairing has become the dominant specification in new developments, particularly where air source heat pumps are installed.
The result is a system that is efficient by design rather than by effort. Homeowners do not need to understand the thermodynamics. They simply experience a warm house and a modest energy bill.
The Commercial Logic
Developers are pragmatists, and underfloor heating makes commercial sense in a new build.
Installation is cheaper when it is planned from the outset. Pipes can be laid before the screed is poured, avoiding the labour and disruption of a retrofit. Radiators require pipework, brackets, and wall space, all of which cost money and complicate the build.
There is also the matter of saleability. Underfloor heating is a feature buyers recognise and value. It signals quality, efficiency, and modernity, and it distinguishes a development from older stock. Marketing suites mention it prominently for good reason.
The Comfort Argument
Efficiency and regulation explain the shift, but comfort sustains it.
Radiators create convection currents, warm air rising to the ceiling while feet stay cold. Underfloor heating warms surfaces directly, producing an even temperature from floor to ceiling. The difference is immediately noticeable, particularly in rooms with hard flooring.
New-build homes are frequently tiled throughout the ground floor, and tiles are the coldest surfaces in any house. Underfloor heating transforms them. The same floors that would otherwise be uncomfortable underfoot become pleasant, and the house feels warmer than the thermostat suggests.
The Design Advantage
There is a further reason developers favour underfloor heating, and it is aesthetic as much as practical.
Radiators occupy wall space. In a compact new-build flat or a narrow townhouse, that space is precious. Removing radiators frees walls for furniture, storage, and art, and makes rooms feel larger and less cluttered.
For developers, this is a selling point. For buyers, it is a daily benefit. A room without a radiator is a room that can be arranged as the occupant wishes.
What the Trade Notices
Radiator Outlet’s perspective is instructive because it sits at the point where specification meets installation.
The trade has noticed several changes. Demand for underfloor heating systems has grown across all property types, not only new builds. Installers have become more experienced with the technology, reducing the risk of poor installation. And homeowners renovating older properties are increasingly asking for underfloor heating as part of the work, even where it requires more effort than a new build.
The supply chain has responded. Systems are now available for a wider range of floor constructions, including low-profile options for retrofits and electric mats for small rooms. The market has matured.
The Caveats Worth Hearing
None of this means underfloor heating is universally straightforward.
Wet systems require sufficient floor depth for insulation, pipe, and screed. In a new build, this is easy to accommodate. In a renovation, it can be a genuine constraint. Electric systems are simpler to install but cost more to run per unit of heat, which makes them best suited to small areas.
Controls matter enormously. A poorly controlled system wastes energy regardless of how efficient the hardware is. Zoning, programmable thermostats, and sensible scheduling are essential to realising the savings that underfloor heating promises.
Installation quality remains the decisive factor. A well-specified system fitted badly will underperform a simpler system fitted well.
The Final Point
Heated floors are becoming standard in new builds because regulation, technology, and commercial logic have aligned. Heat pumps need low flow temperatures. Building standards demand efficiency. Developers want a marketable feature. Buyers want comfort and lower bills.
Underfloor heating delivers on all of these counts, and the trade has noticed. Radiator Outlet’s experience reflects a broader shift: what was once a luxury specification is now the default, and the homes being built today will increasingly be warm underfoot by design.
For anyone buying a new build, the question is no longer whether underfloor heating is worth it. It is whether any other system makes sense at all.
