How the job changes from property to property
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), and use for more than cooling alone. Listed building curtilages are excluded.
Air source heat pumps in Crow's Green
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. If the problem is questions about where the outdoor unit can go and radiators that may be too small for a heat pump, we can help.
For a home around Crow's Green that’s off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out 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.

Your questions about air source heat pumps in Crow's Green
Is Crow's Green within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Can I fit a heat pump in Crow's Green without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Crow's Green holds about 19 listed buildings and structures. 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 the local planning authority (for Crow's Green, normally Braintree council).
What VAT do I pay on a heat pump?
Heat pumps in homes carry 0% VAT until 31 March 2027, with 5% from 1 April 2027. It doesn’t apply to businesses, and this is general information rather than tax advice.
Am I eligible for a heat pump grant?
We confirm eligibility at the survey stage. Only one grant is available per property, it can’t replace a low-carbon system, and hybrids don’t qualify and other conditions apply.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Only in limited cases, with a grant of £2,500. The system must replace the existing fossil-fuel heating, meet the home’s full heating demand, be installed by an MCS certified installer and be in a home.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Air source heat pumps in Crow's Green: the local picture
About 88% of households live in detached or semi-detached houses, according to the last census (2021). Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of St James, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Running several properties is easier with one contractor. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
What happens on the day
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Seeing the property in pictures first means the trip to Crow's Green can be planned properly.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Preparing for the visit
- Move furniture away from the wall where we’ll be working
- Let us know where the consumer unit is
- Let us know where we can park and unload
