How we handle air source heat pumps in Great Haseley

As an MCS certified installer, we fit air source heat pumps for homes in Great Haseley and the rest of Oxfordshire. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We’ll explain which type fits your home and why. The work covers hot water cylinders, radiator systems and underfloor heating, and people most often call us about checking eligibility for a heat pump grant and ageing boilers that will need replacing.

If your home in or near Great Haseley is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.

Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Leave it or put it right?

From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you’re thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. Booking before summer means the work in Great Haseley is done before the hot weather.

Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, ring 07833 053749 or fill in the contact form for straight advice and a fixed price.

Questions from Great Haseley

Do you cover smaller places like Great Haseley?

Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.

Is a heat pump in Great Haseley permitted development?

It depends on the property. The Great Haseley Conservation Area takes in the middle of Great Haseley. 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 don’t 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, typically the authority for Great Haseley.

What accreditations do you have?

We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.

Am I eligible for a heat pump grant?

That depends on the scheme conditions, which we check for you. As the installer, we make the application where you qualify.

Is there a Boiler Upgrade Scheme grant for air-to-air?

The air-to-air grant is £2,500, and only some homes qualify. The system has to replace the fossil-fuel heating and heat the whole home, installed by an MCS certified installer.

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 though not every home qualifies.

Who has to arrange F-Gas leak checks?

The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

What we do, step by step

If the system has to be off for part of the visit, we tell you before we start so it does not catch you out. For businesses, we can normally work room by room or zone by zone. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Somewhere like Great Haseley, it helps to know about lanes, gates and where to park.

  1. Step one is understanding the house, how it’s heated today and what you’d like to change.
  2. A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
  3. We send a fixed-price quote that shows the equipment, the grant position and the VAT.
  4. Installation covers the outdoor unit, the indoor connections and the controls.
  5. The system is commissioned and registered under MCS, and we show you how to use it.

Getting ready for the visit

  • Clear the space around the indoor unit, or where it will go
  • Make sure we can reach the outdoor unit, or where it will go
  • Keep pets out of the rooms we’re working 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.

For landlords and property managers

For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.

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.

What a customer said

“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.”
