How the job changes from property to property
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source, and is MCS certified when we install it.
The Boiler Upgrade Scheme
There’s one grant per property, and you can’t get a grant to replace a low-carbon system, and hybrid systems are not eligible.
Air source heat pumps for homes and businesses in Caldecote
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. If you are dealing with an oil, LPG or gas boiler near the end of its life and questions about listed buildings or conservation areas, we can help.
Space for an outdoor unit is rarely an issue near Caldecote, so the design comes down to heat loss, radiators and hot water.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

What we do, step by step
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Work in Caldecote is booked in advance at a time that suits you.
- First we find out about the property, the heating you have now and what you’re hoping for.
- 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.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Have the make and model of any existing unit to hand
- Mention any managing agent or landlord rules we need to follow
- Tell us about access, such as roof hatches, high walls or locked plant areas
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Heat pumps in Caldecote: local notes
In the mile around Caldecote’s centre, 2 conservation areas have been designated. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at North Hertfordshire council, which typically handles Caldecote where necessary. Valuation Office Agency council tax records show about 51% of homes in and around Caldecote were built in 2000 or later, and about 68% of households live in detached or semi-detached houses, according to Census 2021 figures. Newer homes usually 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.
If your home is listed, like Hinxworth Place about 0.6 miles north, listed building consent comes before any heat pump work. Older homes near St Mary Magdalene's Church may need extra checks for planning and heat loss before a heat pump is designed.

Caldecote questions
Does the Boiler Upgrade Scheme cover homes in Caldecote?
Caldecote is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Can you do air source heat pumps in Caldecote?
Yes. Caldecote is one of the places we cover. To start, call 07833 053749 or write to us at info@aircondoctor.co.uk with a few pictures.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
How long does a heat pump installation take?
It takes a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do I need planning permission for a heat pump?
Often not in England, as many heat pumps on houses are permitted development provided the conditions are met. These include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), not being used solely for cooling and not being within the curtilage of a listed building.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
