Crosswater air source heat pumps
Air source heat pumps for Crosswater, from F-Gas certified engineers, with the manufacturer’s warranty terms explained on your quote. Enquiries answered the same working day.
- An oil, LPG or gas boiler near the end of its life
- Moving away from fossil-fuel heating
- Questions about listed buildings or conservation areas
How it works
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it 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. If a lane or gateway near Crosswater is tight for a van, let us know and we’ll plan for it.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Move furniture away from the wall where we will be working
- Mention any parking restrictions near the property
- Dig out any previous service or F-Gas records

How we handle air source heat pumps in Crosswater
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers hot water cylinders, air-to-air heat pumps and homes heated by oil, LPG or gas, and people most often call us about working out whether radiators need upsizing and deciding which kind of heat pump suits the home.
Homes around Crosswater typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Common problems we fix in Crosswater
Some homes heated by electric heaters or storage heaters consider a heat pump instead. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
Most people get in touch when they notice one of these:
- Choosing between air-to-water and air-to-air
- Questions about the Boiler Upgrade Scheme
- Radiators that may be too small for a heat pump
Live in one of the older houses around St John the Evangelist? Expect the survey to look closely at heat loss and at the building’s planning status.

FAQs for Crosswater
Do you cover smaller places like Crosswater?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Is the heat pump grant available in Crosswater?
Yes, if the home and the heat pump meet the scheme’s rules: Crosswater is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Will I need planning consent for an air source heat pump?
In England, many air source heat pumps on houses can be permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
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. Air-to-air doesn’t heat hot water, and we explain which suits your home.
What does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
Who is responsible for leak checks?
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’ll work out which band applies to yours.
Landlords, agents and facilities managers
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
What you can do yourself, and what needs us
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
