How we handle air source heat pumps in Herongate
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Sizing by rule of thumb is not good enough. If the problem is working out whether radiators need upsizing and finding a place for the outdoor unit, we can help.
In a place like Herongate, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Why it’s worth doing now in Herongate
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. An early booking makes the visit to Herongate easier to arrange.
What you pay depends on the type of system and how many units are involved, the access and what the work involves. You get a fixed price before work begins, so you know where you stand.

Air source heat pumps around Herongate
The middle of Herongate is part of the Herongate Conservation Area. Draw a one-mile circle round the middle of Herongate and it takes in 2 conservation areas. Berrie House, listed at grade II, is one of roughly 22 protected buildings and structures in the half-mile around Herongate’s centre. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? About 43% of homes across Herongate and its surrounding area date from 1945 to 1972, according to VOA council tax data, and the last census (2021) found about 80% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses normally have space for an outdoor unit and a hot water cylinder.
Period properties close to St Andrew's Church can suit a heat pump, though insulation and any heritage protection are checked first.

What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors.

When to call us in Herongate
Extensions, renovations and loft conversions are a natural time to rethink the heating. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
These are the situations we see most often:
- Checking emitters for a heat pump
- Wanting to stop using oil, LPG or gas for heating
- Checking eligibility for a heat pump grant
Ingatestone Hall, roughly 4.8 miles north, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

Herongate questions
Do you cover smaller places like Herongate?
Yes. Herongate is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Is the heat pump grant available in Herongate?
Yes, if the home and the heat pump meet the scheme’s rules: Herongate is in England, where it applies. 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. You do not apply yourself: the MCS certified installer does, which is us.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we’re happy to show ours.
