How we handle air source heat pumps in Preston
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers underfloor heating, hot water cylinders and radiator systems, and people most often call us about comparing heat pump types and plans to switch to electric heating with a heat pump.
For a home around Preston that is 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.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Preston: your questions answered
Is the heat pump grant available in Preston?
Preston is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
Can I fit a heat pump in Preston without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Preston is in the Preston Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the planning department at North Hertfordshire council, normally the authority for Preston first.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
Will skipping a service affect the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
Do you cover Preston?
Yes. We work in Preston and across Hertfordshire, as part of our area across London and the South East. For a fixed-price quote, call us on 07833 053749 or fill in the contact form.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Preston and across Hertfordshire. Tell us who should receive the paperwork.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
Homes in Preston and heat pumps
The last census (2021) found about 72% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
If your home is listed, like Knebworth House about 3.9 miles south-east, listed building consent comes before any heat pump work. Live in one of the older houses around Church of St Martin? Expect the survey to look closely at heat loss and at the building’s planning status.

Other services in Preston
Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Pricing air source heat pumps in Preston
Jobs vary more than people expect. What affects the quote:
- The type of system, from a single split to a larger system
- Whether the existing supply is suitable
- How far the pipework has to run, and where
Height, access and the distance between the indoor and outdoor units can all change the price. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
Simple jobs can often be priced from photos and some basics. Useful things to send:
- Photos showing the indoor unit and the space around it
- The postcode and whether it’s a home, flat or business
- Where the outdoor unit is, or where you’d like it
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We agree a date with you and plan the visit to Preston so we arrive with what’s needed.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- The system is commissioned and registered under MCS, and we show you how to use it.
Getting ready for the visit
- Mention any parking restrictions near the property
- Unlock any gate, garage or side passage we need
- Plan for pets to be kept clear during the visit
