About our air source heat pumps in Newnham
An air-to-water heat pump costs £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 the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. If the problem is radiators that may be too small for a heat pump and deciding on the outdoor unit position, we can sort it out.
In a place like Newnham, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

FAQs for Newnham
Do you cover smaller places like Newnham?
Yes. Newnham is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Newnham?
Yes, if the home and the heat pump meet the scheme’s rules: Newnham is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You don’t apply yourself: the MCS certified installer does, which is us.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you survey before quoting?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.
Is a heat pump permitted development?
Under the Planning Portal rules, a heat pump on a house can often be permitted development. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter. We check what applies to you.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the trip to Newnham around you.
- 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.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Mention any parking restrictions near the property
- Arrange for someone to be there to let us in
- Let us know if the units are on a roof, a high wall or in a locked area

Advice
Common problems we fix in Newnham
Many enquiries start with a question about the Boiler Upgrade Scheme. Whether you can get the grant depends on your home and the scheme conditions, so we check before you commit.
Customers normally contact us when they notice one of these:
- Moving away from fossil-fuel heating
- No space for a hot water cylinder
- Ageing boilers that will need replacing
Older homes near Church of St Vincent may need extra checks for planning and heat loss before a heat pump is designed.
Before you book anyone
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether extra work needs your approval first
- If the quote is based on a survey, photos or a diagnosis
Aftercare tips
Simple habits make a real difference. We recommend:
- Know the servicing conditions in your warranty
- File the MCS certificate safely
- Clear leaves and debris from the outdoor unit
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we will explain the settings for your home.
Don’t cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. 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.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.

Air source heat pumps around Newnham
The middle of Newnham is part of the Newnham Conservation Area. About 11 listed entries lie within half a mile of central Newnham, Church of St Vincent (grade II*) among them. Where a home is affected, the outdoor unit position is settled with North Hertfordshire council, typically the planning authority here before the heat pump design is finished. About 51% of homes across Newnham and its surrounding area have been built since 2000, according to VOA council tax data, and about 68% of households live in detached or semi-detached houses, according to the last census (2021). Newer homes normally lose less heat, which tends to suit a heat pump well. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Historic houses such as Hinxworth Place, about 1.4 miles north, are a reminder that listed homes need consent before a heat pump goes in.
