About our air source heat pumps in Three Oaks
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers air-to-water heat pumps, underfloor heating and radiator systems, and the jobs we see most are choosing between air-to-water and air-to-air and finding a place for the outdoor unit.
For a home around Three Oaks 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.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Why deal with it now?
The two types suit different homes and needs. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases. We explain which makes sense for you. A system that’s left with a fault, or without a service, typically costs more to run.
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.

Homes in Three Oaks and heat pumps
The coast is only about 3 miles from Three Oaks. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. About 85% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses typically have space for an outdoor unit and a hot water cylinder. Central Three Oaks is inside a conservation area. Historic England lists about 4 buildings and structures within half a mile of the centre of Three Oaks, including Rose Cottage (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
If you live near Three Oaks station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Historic houses such as Durhamford Manor, about 4.9 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes from a couple of days to around a week, depending on the system and how much of the heating changes.

Advice
What owners can safely do
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or write to us at info@aircondoctor.co.uk.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Three Oaks questions
Is the heat pump grant available in Three Oaks?
Three Oaks is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You do not apply yourself: the MCS certified installer does, which is us.
Does sea air affect air conditioning in Three Oaks?
It can, as Three Oaks is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Should I choose air-to-water or air-to-air?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source, and we explain which suits your home.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Will I need planning consent for an air source heat pump?
It depends on the property and where the unit goes. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights, so we check during the survey.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Will I get records for the system?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
When it’s something else
To be straight with you, some problems need a different answer:
- Draught-proofing and insulation upgrades
- Planning decisions, which rest with the council
- A grant for a home that doesn’t meet the scheme rules
If you are not sure, just phone us on 07833 053749 and we will give you a straight answer.
