Which Houses Are Not Suitable for Heat Pumps?

Most UK Homes Are Suitable

The good news is that the vast majority of UK homes are suitable for heat pump installation. Detached, semi-detached, and end-terrace houses are all excellent candidates. Even mid-terrace properties and some flats can accommodate heat pumps with careful design.

The key requirements are: space for an outdoor unit (about 1m x 0.5m), adequate insulation (though the EPC requirement has been removed), and a suitable location that complies with planning and noise regulations. Most homes meet all of these criteria.

Properties That May Be Challenging

Some properties present challenges for heat pump installation, though 'challenging' doesn't mean 'impossible'. These include: very poorly insulated homes where heat loss is extreme, properties with no outdoor space for the unit, listed buildings where external modifications are restricted, and very compact flats with no access to an external wall.

Even in these cases, solutions often exist. Poorly insulated homes can benefit from insulation improvements first. Listed buildings may qualify for permitted development rights. High-rise flats might suit communal heating schemes. A professional survey will identify the best approach.

What Makes a Home Ideal for a Heat Pump?

The ideal properties for heat pumps are well-insulated homes with space for an outdoor unit and either radiators or underfloor heating. Properties with south or west-facing gardens are ideal for the outdoor unit placement, but any orientation can work.

Homes currently heated by oil, LPG, or electric heating are the best candidates, as they'll see the largest savings. Gas-heated homes also benefit, with typical savings of £300-£600 per year. Properties with solar panels are particularly well-suited, as the free electricity can power the heat pump.
