Room-by-room heat loss
We work out how much heat each room loses on a cold day, so the heat pump and radiators are sized for your house, not a rule of thumb.
Cheltenham is known for its Regency architecture, alongside plenty of 20th-century and new homes. Whatever the age of your house, a heat pump starts with a room-by-room heat loss survey, so it’s sized for how your home really holds heat.
With around 2,600 listed buildings and seven conservation areas in the town, we also check where the outdoor unit is allowed to go.

Usually, yes. An older home needs a bit more planning, not a different technology.

Loft insulation, draught-proofing and secondary glazing can cut heat loss without changing how a period home looks. Some changes to listed buildings need consent.
Heat pumps run radiators cooler. Big cast iron radiators often work well; some rooms may need a larger radiator.
A hot water cylinder, often in an airing cupboard, utility room or the loft.
A little colder than Bristol or Gloucester, and well within what air source heat pumps are designed for.
Between 2005 and 2023, Cheltenham averaged around 413 hours a year below freezing, and only about 16 hours a year below −5°C. The coldest hour in those 19 years was about −11°C, in January 2013.
MCS installers size a heat pump for a design temperature for your area, so it keeps your home warm on the coldest days, not just an average one.

Hourly 2-metre air temperatures from PVGIS (European Commission JRC) for one point in each town. Your survey uses the design temperature for your postcode.
Most heat pumps are permitted development, as long as they pass the MCS 020a noise check. In Cheltenham, two things come up often.
In Cheltenham’s seven conservation areas, the outdoor unit can’t go on a wall or roof facing a road, or nearer the road than any part of the house. Rear gardens and courtyards usually work.
Permitted development doesn’t apply in the grounds of a listed building, so you’ll need planning permission, and listed building consent is likely for work to the building itself.
Cheltenham Borough Council’s Climate Change SPD, adopted in June 2022, covers retrofit and is used when planning decisions are made.
Rules from the Planning Portal. Permitted development rights can be removed by a planning condition or an Article 4 Direction, so we check your address at the survey.
We’ll suggest the least intrusive spot for the outdoor unit and the pipe runs, and give you the details you need for your application.
An air-to-air heat pump heats rooms directly through indoor units, and can cool them in summer. It now qualifies for a £2,500 Boiler Upgrade Scheme grant.
About 27% of Cheltenham homes are flats, including flats in converted houses.

Room-by-room heat loss, radiators, cylinder space, and whether your home is listed or in a conservation area.
Most homes go straight to installation. Listed homes need consent from Cheltenham Borough Council first.
Outdoor unit, cylinder, any radiator changes and controls, with the house kept as tidy as we found it.
We claim the grant, register the install with MCS and show you how to get the best from your controls.

Including the period-home and planning questions we’re asked most in Cheltenham.
Yes, with permission. Permitted development doesn’t apply within the grounds of a listed building, so the heat pump needs planning permission, and listed building consent is likely to be needed for work to the building itself, such as new pipe runs. With around 2,600 listed buildings in Cheltenham, it’s worth checking early. We’ll suggest the least intrusive spot for the unit. See the council’s listed buildings guidance.
Not at the front, in most cases. In Cheltenham’s seven conservation areas, a heat pump can’t go on a wall or roof that faces a road, or be nearer the road than any part of the house. A rear garden, courtyard or side wall that doesn’t face the road usually works. You can check your address on the council’s conservation area map.
Not necessarily. The heat loss survey shows where your home loses heat. Simple fixes like loft insulation and draught-proofing can mean a smaller heat pump and lower running costs, so we’ll tell you if they’re worth doing first. On a listed building, check before changing windows, walls or floors.
Often, yes. Heat pumps run radiators at lower temperatures, so what matters is whether each radiator is big enough for its room. Large cast iron radiators often are. The room-by-room survey shows which rooms, if any, need a bigger radiator.
Yes. The Boiler Upgrade Scheme now includes £2,500 towards an air-to-air heat pump. Air-to-air units heat rooms directly through indoor units, and can cool them in summer, but they don’t heat your hot water, so you’d keep a separate way of doing that. To be permitted development, a heat pump can’t be used only for cooling. See GOV.UK.
Its Climate Change Supplementary Planning Document, adopted in June 2022, sets out how the council expects buildings to respond to climate change, including retrofit, and is used when it decides planning applications. Most heat pumps don’t need an application, but it’s useful reading for listed and conservation area homes. See the council’s SPD page.
