Air source heat pumps in Marsh Baldon
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you will need another way to do that. Common call-outs are for no space for a hot water cylinder and questions about the Boiler Upgrade Scheme, across air-to-air heat pumps, hot water cylinders and underfloor heating.
Older and listed homes in villages like Marsh Baldon need extra care, and permitted development does not cover listed buildings, so we check consent first.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What affects the cost of air source heat pumps
A fixed price needs a few facts first. We check:
- The distance and route between the indoor and outdoor units
- The type of system, from a single split to a larger system
- Which make and model is being fitted or worked on
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before work begins, with VAT shown clearly.
What we need to know
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- A few pictures of the room and the wall the unit is on, or will go on
- A short video of any fault, such as a noise or a flashing light
- The rating plate or label on any existing unit
To help us quote: the address and the type of property, a few pictures, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, phone us on 07833 053749.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
System by system
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme covers England and Wales: £7,500 for air-to-water and ground source, and £2,500 for air-to-air in limited cases. The installer applies.
What we do, step by step
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. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. A few pictures help us make the most of a visit to Marsh Baldon.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Mention any managing agent or landlord rules we need to follow
- Make sure we can reach the consumer unit or fuse board
Getting a price
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.

Homes in Marsh Baldon and heat pumps
Marsh Baldon’s centre falls inside the Marsh Baldon Conservation Area. 2 conservation areas lie within a mile of central Marsh Baldon. Church of St Peter, listed at grade II*, is one of roughly 54 protected buildings and structures in the half-mile around Marsh Baldon’s centre. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at South Oxfordshire council, which usually handles Marsh Baldon where needed. Census 2021 figures found about 64% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
With Garsington Manor about 2.2 miles north-east, it’s worth asking whether your own home is listed before planning a heat pump. Period properties close to Church of St Peter can suit a heat pump, though insulation and any heritage protection are checked first.

Your questions about air source heat pumps in Marsh Baldon
Is Marsh Baldon within the area you cover?
Yes. Marsh Baldon is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Marsh Baldon?
Marsh Baldon 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. The installer applies, and we’re MCS certified.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
What does an air-to-water heat pump cost?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
A customer’s words
“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.”
