FAQs for Essendon
Does the Boiler Upgrade Scheme cover homes in Essendon?
Yes, the scheme covers homes in England, including Essendon, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we are MCS certified.
Can I fit a heat pump in Essendon without planning permission?
That depends on the building and where the outdoor unit goes. The Essendon Conservation Area is close to the centre of Essendon. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the local planning authority (for Essendon, usually Welwyn Hatfield council).
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
Can I do any of the installation myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you offer emergency call-outs?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
What does an air-to-water heat pump cost?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. The final price depends on the heat loss survey, the radiators and the cylinder, and you get a fixed-price quote.
Air source heat pumps in Essendon
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. Typical jobs include deciding which kind of heat pump suits the home and working out where a cylinder could go, across radiator systems, hot water cylinders and homes heated by oil, LPG or gas.
Homes around Essendon typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Heat loss surveys

Why act early in Essendon
Permitted development rules can change, and conditions vary between properties. Checking the position for your home at the survey stage avoids surprises later, including conservation areas, listed buildings and Article 4 directions. Dealing with it now is usually simpler than a breakdown later.
One room or a whole building, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before work begins, and the quote sets out the VAT.

Homes in Essendon and heat pumps
About 67% of homes in the Essendon area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 45% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. In a terrace, the outdoor unit position and the MCS noise check need particular care.
Period properties close to Church of St Mary the Virgin can suit a heat pump, though insulation and any heritage protection are checked first. If your home is listed, like Hatfield House about 2.4 miles west, listed building consent comes before any heat pump work.
