About our air source heat pumps in Nettleden
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Common call-outs are for deciding which kind of heat pump suits the home and checking emitters for a heat pump, on air-to-water heat pumps, homes heated by oil, LPG or gas and air-to-air heat pumps.
Older and listed homes in villages like Nettleden need extra care, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos of the existing unit help with repairs and servicing in Nettleden.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Name a contact who can meet us at the agreed time
- Let us know where we can park and unload
Getting a quote
The quickest way to a quote is to send photos: 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.
Advice
How the job changes from property to property
Hot water cylinders
An older cylinder may not suit a heat pump, and we explain whether yours can stay.
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed building consent is a separate matter, and we check the position for your property.
What affects the cost of air source heat pumps
Our prices page gives typical ranges, but every job is priced on its own. The quote depends on:
- What state the existing equipment is in
- Which make and model is being fitted or worked on
- The type of system, from a single split to a larger system
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll talk you through it.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Where the outdoor unit is, or where you’d like it
- Photos showing the indoor unit and the space around it
- The address and the type of property
For a fixed-price quote, phone 07833 053749 or email us and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.

Questions from Nettleden
Do you cover smaller places like Nettleden?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Nettleden?
Yes, the scheme covers homes in England, including Nettleden, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. The installer applies, and we’re MCS certified.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
What’s the price of a heat pump installation?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.

Air source heat pumps in Nettleden: the local picture
The centre of Nettleden lies within the Nettleden Conservation Area. In the mile around Nettleden’s centre, 4 conservation areas have been designated. Historic England lists about 16 buildings and structures within half a mile of the centre of Nettleden, including Church of St Lawrence (grade II*). Where a home is affected, the outdoor unit position is settled with the local planning authority (normally Dacorum council) before the heat pump design is finished. VOA council tax data date about 73% of homes in and around Nettleden to the post-war years, 1945 to 1972, and about 52% of households live in terraced houses, according to Census 2021 figures. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.
Every heat pump design starts with a room-by-room heat loss calculation.
