About our air source heat pumps in Ayot St Peter
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers air-to-water heat pumps, air-to-air heat pumps and hot water cylinders, and the jobs we see most are not knowing whether a grant applies and choosing between air-to-water and air-to-air.
For a home around Ayot St Peter that’s off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.

Questions from Ayot St Peter
Do I need planning permission for a heat pump in Ayot St Peter?
That depends on the building and where the outdoor unit goes. Around 9 listed entries sit within 0.5 miles of central Ayot St Peter. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Ayot St Peter, normally Welwyn Hatfield council).
Do you cover smaller places like Ayot St Peter?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
When to call us in Ayot St Peter
A common reason is wanting to stop burning gas, oil or LPG. A heat pump runs on electricity and takes heat from the outside air, which is why it fits that aim.
Most people get in touch after spotting something like this:
- Moving away from fossil-fuel heating
- Questions about the Boiler Upgrade Scheme
- Ageing boilers that will need replacing
Historic houses such as Shaw's Corner, about 1.4 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.

Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we will explain the settings for your home.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
