Netteswell air source heat pumps
We cover Netteswell for MCS certified installation of air source heat pumps for heating and hot water, with the Boiler Upgrade Scheme grant applied for. Diagnosis first, a fixed price and proper paperwork when we finish.
- Replacing a combi boiler with a heat pump
- A boiler that is getting old
- Comparing heat pump types
Landlords, agents and facilities managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we’ll copy in whoever needs it.
Air source heat pumps in Netteswell, done properly
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. Typical jobs include questions about listed buildings or conservation areas and wanting to stop using oil, LPG or gas for heating, across air-to-air heat pumps, underfloor heating and radiator systems.
If your home near Netteswell has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme, for an air source or ground source heat pump.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What air conditioning will not do
An honest diagnosis matters more to us than a booking, so here’s what air source heat pumps will not do:
- Grants for hybrid systems or replacements of low-carbon systems
- Tax rulings, which only HMRC can give
- Planning decisions, which rest with the council

FAQs for Netteswell
Is planning permission needed for a heat pump in Netteswell?
There’s no single answer: the building and the outdoor unit position decide it. The Town Park and Netteswell Cross Conservation Area is close to the centre of Netteswell. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Harlow council, which is typically the planning authority for Netteswell.
Can I get the Boiler Upgrade Scheme grant in Netteswell?
Yes, if the home and the heat pump meet the scheme’s rules: Netteswell is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
What’s the price of a heat pump installation?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
Do I need new radiators for a heat pump?
It varies from room to room. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do you need air source heat pumps in Netteswell?
Some homes heated by electric heaters or storage heaters consider a heat pump instead. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
What we are most often called about:
- Replacing a combi boiler with a heat pump
- Questions about the Boiler Upgrade Scheme
- Planning and permitted development questions
If your home is one of the older properties near St Andrew's Methodist Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
What to look for in a quote
- Whether the company is F-Gas certified, and whether you can check it
- Whether the quote shows VAT clearly
- Whether the quote is a fixed price
Homes in Netteswell and heat pumps
VOA council tax data date about 73% of homes in the Netteswell area to the post-war years, 1945 to 1972, and the 2021 Census found about 48% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.
Homeowners near Harlow Town station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
