Air source heat pumps across Cow Roast

How the visit works

Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the room and the outside of the property help us plan a visit to Cow Roast.

  1. We talk through your home, your current heating and what you want from a heat pump.
  2. On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
  3. The price comes back fixed and in writing, with the grant and VAT shown line by line.
  4. Installation covers the outdoor unit, the indoor connections and the controls.
  5. We commission the heat pump, complete the MCS paperwork and talk you through the controls.

Getting ready for the visit

  • Mention any roof access, ladders or high-level work
  • Dig out any previous service or F-Gas records
  • Name a contact who can meet us at the agreed time

Getting a quote

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Advice

Air source heat pumps for homes and businesses in Cow Roast

Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it does not apply to businesses, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers radiator systems, air-to-air heat pumps and hot water cylinders, and common reasons people get in touch are an oil, LPG or gas boiler near the end of its life and no space for a hot water cylinder.

For a home around Cow Roast that’s off mains gas and heated by oil or LPG, 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.

Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Air source heat pumps around Cow Roast

About 72% of households live in detached or semi-detached houses, according to the 2021 Census. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.

With Cholesbury Manor House about 2.7 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump. Live in one of the older houses around Church of St Bartholomew (church of England)? Expect the survey to look closely at heat loss and at the building’s planning status.

Cow Roast questions

Do you cover smaller places like Cow Roast?

Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.

Can I fit a heat pump in Cow Roast without planning permission?

There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Cow Roast holds about 5 listed buildings and structures. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the planning department at Dacorum council, normally the authority for Cow Roast.

Does servicing affect my warranty?

It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.

Will I get records for the system?

Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.

Can I fit air conditioning or a heat pump myself?

No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.

Do I need new radiators for a heat pump?

We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.

What VAT do I pay on a heat pump?

Under HMRC Notice 708/6, a heat pump installed in a home is zero-rated until 31 March 2027 and 5% after that. For air-to-air systems, we confirm the VAT on your quote.

What owners can safely do

Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or email us.

Different systems, different jobs

The Boiler Upgrade Scheme

There’s one grant per property, and you can’t get a grant to replace a low-carbon system, and hybrid systems are not eligible.

Radiators and underfloor heating

At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.

For landlords and property managers

If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so the files stay tidy.

Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.

From one of our customers

“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.”
