Air source heat pumps for homes and businesses in Codicote Bottom
We install air source heat pumps in Codicote Bottom and across Hertfordshire, and we are MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. Typical jobs include checking whether planning permission is needed and choosing between air-to-water and air-to-air, across hot water cylinders, air-to-water heat pumps and radiator systems.
For a home around Codicote Bottom that’s off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What we are called out for in Codicote Bottom
When a home is being extended or renovated, it’s a good moment to look at heat pumps. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
Most people get in touch when they notice something like this:
- A boiler that’s getting old
- Comparing heat pump types
- Checking eligibility for a heat pump grant
Shaw's Corner, roughly 1.3 miles south-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
Comparing quotes
- Whether the company is F-Gas certified, and whether you can check it
- How extra work would be agreed if they find something unexpected
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
What happens on the day
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Codicote Bottom, the timing is set with you and the travel is our side of the planning.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Tell us about parking and loading
- Mention any roof access, ladders or high-level work
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.

When something else is needed
Not every problem is solved by air source heat pumps, and we’ll tell you before any work starts. It does not solve:
- Draught-proofing and insulation upgrades
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Grants for hybrid systems or replacements of low-carbon systems
Not sure which it is? You can call 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll tell you honestly.

FAQs for Codicote Bottom
Do I need planning permission for a heat pump in Codicote Bottom?
That depends on the building and where the outdoor unit goes. Historic England lists about 29 buildings and structures within half a mile of the centre of Codicote Bottom. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask North Hertfordshire council, which is typically the planning authority for Codicote Bottom.
Does the Boiler Upgrade Scheme cover homes in Codicote Bottom?
Codicote Bottom is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do I get paperwork after the visit?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.
Owner checks or an engineer?
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
