Is Underfloor Heating Worth It for Your Home? Pros and Cons

As energy efficiency and comfort become top priorities for UK homeowners and property developers, underfloor heating (UFH) is increasingly being considered as an alternative (or addition) to traditional radiators. But is it really worth the investment?

At Pleasant Plumbers, we’ve installed underfloor heating in everything from new-build homes to luxury apartment blocks and commercial buildings across London. Here’s what you need to know before you decide.

Underfloor heating uses a network of pipes (wet systems) or electric heating mats (dry systems) beneath your flooring to evenly heat the space from the ground up. It creates radiant heat, warming objects and people directly—rather than just heating the air like a radiator.

1. Even Heat Distribution

Unlike radiators, which heat only certain parts of a room, UFH spreads warmth evenly—eliminating cold spots.

2. Space-Saving Design

No bulky radiators = more room for furniture and decor. This is particularly popular in minimalist and modern interiors.

3. Increased Energy Efficiency

UFH runs at a lower temperature (typically 27–29°C) compared to radiators (65–75°C), making it up to 25% more efficient when properly installed and insulated.

4. Enhanced Comfort

Warm floors underfoot—especially in kitchens, bathrooms and open-plan living areas—create a luxurious feel.

5. Improved Air Quality

With no air being blown around (unlike with forced air or radiator convection), there's less dust movement—ideal for allergy sufferers.

6. Higher Property Value

Underfloor heating is a premium feature that appeals to buyers and tenants, particularly in high-end London properties.

1. Higher Initial Cost

Installation (especially wet systems) can be costly—ranging from £60–£120 per m² depending on your flooring and system type. Retrofitting is more expensive than new builds.

2. Longer Warm-Up Time

UFH heats slower than radiators, though it retains heat longer. Not ideal if you need quick bursts of heat.

3. Installation Disruption

Retrofitting requires lifting flooring and potentially altering insulation and screed—often not suitable for listed or older London homes without significant work.

4. Flooring Compatibility

Not all floors are suitable. Some hardwoods and thick carpets reduce efficiency unless carefully selected and fitted.

Underfloor heating is ideal if:

• You're building or renovating
• You want long-term efficiency and comfort
• You're aiming for a high-end, radiator-free finish
• You manage luxury rentals or commercial properties seeking modern heating solutions

For homes and properties in London, UFH is especially valuable in bathrooms, kitchens, and large open-plan spaces, where wall space is limited and style is key.
