Air source heat pumps for Radwell

Air source heat pumps in Radwell

Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers radiator systems, air-to-water heat pumps and hot water cylinders, and people most often call us about replacing a combi boiler with a heat pump and not knowing whether a grant applies.

In a place like Radwell, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Questions from Radwell

Do you cover smaller places like Radwell?

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

Is planning permission needed for a heat pump in Radwell?

It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 3 buildings and structures within half a mile of the centre of Radwell. 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 cannot face a road. Where necessary, we check with North Hertfordshire council, which is normally the planning authority for Radwell.

Do you offer maintenance contracts?

Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.

Is the equipment covered by a warranty?

It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.

Which type of heat pump is right for my home?

The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.

What VAT do I pay on a heat pump?

Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. Hotels and businesses pay the standard rate. Please treat this as general information, not tax advice.

Can I fit air conditioning or a heat pump myself?

Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.

What air source heat pumps can’t fix

We’d rather tell you now than sell you work that will not help, so these are the things it will not cover:

  • Improving the building’s insulation
  • Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
  • Getting planning permission or listed building consent on your behalf

If you’re not sure, just ring us on 07833 053749 or drop us a line and we’ll give you a straight answer before you book.

What the work covers

  • Hot water cylinders
  • Homes heated by oil, LPG or gas
  • Radiator systems
  • Underfloor heating
  • Air-to-air heat pumps

Homes in Radwell and heat pumps

The Valuation Office Agency’s council tax figures show about 51% of homes in and around Radwell were built in 2000 or later, and Census 2021 figures found about 68% of households in detached or semi-detached houses. Newer homes typically lose less heat, which tends to suit a heat pump well. Houses normally have space for an outdoor unit and a hot water cylinder.

If your home is one of the older properties near Church of All Saints, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Hinxworth Place, roughly 2.4 miles north, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Why it’s worth doing now in Radwell

Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for while the old heating still works. Dealing with it now is normally simpler than a breakdown later.

Typical ranges are on our prices page, but each job is priced on what it involves. For a fixed-price quote, ring 07833 053749, or email if that’s easier, and we will talk you through it.

Aftercare tips

Systems last better with the right care. We suggest:

  • Keep the outdoor unit clear all year
  • Use the settings explained at handover
  • File the MCS certificate safely

After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.

Let the heat pump run steadily rather than switching it on and off as explained at handover.

What we do, step by step

The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. If a lane or gateway near Radwell is tight for a van, let us know and we’ll plan for it.

  1. We start with your plans and the property.
  2. The survey checks heat loss, emitters, hot water and the outdoor unit position.
  3. We explain which type of heat pump suits the home and whether a grant could apply.
  4. We install the heat pump and connect it up.
  5. After commissioning, you get the MCS certificate and a handover.

Preparing for the visit

  • Let us know where the consumer unit is
  • Tell us about parking and loading
  • Find the manual or the paperwork for the system, if you have it

“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.”
