Air source heat pumps in Dial Post

Air source heat pumps in Dial Post, done properly

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 look at the planning position for your home during the survey. If the problem is checking eligibility for a heat pump grant and ageing boilers that will need replacing, we can sort it out.

Space for an outdoor unit is rarely an issue near Dial Post, so the design comes down to heat loss, radiators and hot water.

Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

What we are called out for in Dial Post

Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.

What we’re most often called about:

  • Radiators that may be too small for a heat pump
  • Questions about the Boiler Upgrade Scheme
  • A boiler that’s getting old

Grant applications go through the MCS certified installer, so that part is handled for you.

What to look for in a quote

  • Whether they looked at the job before pricing it
  • Whether you get F-Gas records where refrigerant is involved
  • Whether the manufacturer’s warranty depends on regular servicing

How to choose an air conditioning engineer

How the visit works

The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the room and the outside of the property help us plan a visit to Dial Post.

  1. We find out about your home and the heating you have now.
  2. A heat loss survey is carried out, room by room.
  3. We design the system, check the radiators and cylinder and look at the outdoor unit position.
  4. You get a fixed price, with any grant and the VAT set out.
  5. We install, commission and register the system under MCS.

Getting ready for the visit

  • Name a contact who can meet us at the agreed time
  • Clear access to the fuse board
  • Keep pets out of the rooms we are working in

Advice

Dial Post: your questions answered

Is Dial Post within the area you cover?

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

Is the heat pump grant available in Dial Post?

Dial Post is covered, as the scheme runs across England and Wales. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we are MCS certified.

Will I need planning consent for an air source heat pump?

That depends on your home and the unit’s position. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights and we look at it during the survey.

Will you work on another installer’s system?

Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.

Does servicing affect my warranty?

Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.

When will I hear back?

You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.

Are my radiators big enough for a heat pump?

That depends on the room’s heat loss and the radiator’s size. We check them all during the survey and the quote shows what’s needed.

How the job changes from property to property

Hot water cylinders

Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.

The Boiler Upgrade Scheme

Eligibility depends on the property and the scheme rules and we confirm it before anything is agreed.

When it’s something else

A few issues sit outside what this work can do:

  • A grant for a home that does not meet the scheme rules
  • Any gas work on the existing boiler
  • Improving the building’s insulation

If in doubt, give us a ring on 07833 053749 or use the quote form and we will say what we think before booking.

What a heat pump looks like in Dial Post

Census 2021 figures found about 74% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. Alma Cottage, listed at grade II, is one of roughly 6 protected buildings and structures in the half-mile around Dial Post’s centre. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at Horsham council, which usually handles Dial Post where needed.

Every heat pump design starts with a room-by-room heat loss calculation.

Dial Post is about 7 miles south of Horsham, in West Sussex. Whether you are in the middle of Dial Post or further out, we cover air source heat pumps, from a single room to a whole building.
