What the work involves, system by system
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source and we install it to MCS standards.
The Boiler Upgrade Scheme
Not every home qualifies and we confirm it before anything is agreed.
Air source heat pumps for homes and businesses in Catslip
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If the problem is comparing heat pump types and deciding on the outdoor unit position, we can help.
If your home in or near Catslip is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Questions from Catslip
Is planning permission needed for a heat pump in Catslip?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Catslip holds about 19 listed buildings and structures. 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 the planning department at South Oxfordshire council, normally the authority for Catslip.
Is the heat pump grant available in Catslip?
Yes, if the home and the heat pump meet the scheme’s rules: Catslip is in England, where it applies. 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 is not an add-on to a boiler. The installer applies, and we’re MCS certified.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Is Catslip in your area?
Yes. Our area takes in London and the counties of the South East, Catslip included.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
How the visit works
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Rural lanes and tight entrances are worth mentioning before a visit to Catslip.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- 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.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any managing agent or landlord rules we need to follow
- Arrange for someone to be there to let us in
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

Air source heat pumps around Catslip
The Valuation Office Agency’s council tax figures date about 41% of homes in Catslip and the neighbourhoods around it to the post-war years, 1945 to 1972. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period.
Historic houses such as Greys Court, about 2.2 miles south-east, are a reminder that listed homes need consent before a heat pump goes in. Older homes near Church of St Bartholomew may need extra checks for planning and heat loss before a heat pump is designed.
