Air source heat pumps near Colworth

About our air source heat pumps in Colworth

As an MCS certified installer, we fit air source heat pumps for homes in Colworth and the rest of West Sussex. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We’ll explain which type fits your home and why. The work covers air-to-air heat pumps, air-to-water heat pumps and radiator systems, and people most often call us about replacing a combi boiler with a heat pump and an oil, LPG or gas boiler near the end of its life.

Space for an outdoor unit is rarely an issue near Colworth, so the design focuses on heat loss and radiators.

Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Different systems, different jobs

Radiators and underfloor heating

Underfloor heating suits a heat pump’s lower flow temperature and we look at it during the survey.

The Boiler Upgrade Scheme

There’s one grant per property, and you can’t get a grant to replace a low-carbon system. Hybrids are excluded.

Air source heat pumps in Colworth: the local picture

Colworth lies within about 3 miles of the sea. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. About 54 miles out from central London, Colworth is part of the South East area we work across.

With Goodwood House about 4 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Colworth is about 2 miles north of Bognor Regis, in West Sussex. For air source heat pumps in and around Colworth, please phone 07833 053749 or send an email for a fixed-price quote.

Safe owner checks

Good habits make our visits easier, not unnecessary. 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.

Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.

The process

Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Seeing the property in photos first means the trip to Colworth can be planned properly.

  1. First we find out about the property, the heating you have now and what you’re hoping for.
  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. Once it’s running correctly, the MCS certificate is issued and we show you the settings.

Before we arrive

  • Have the make and model of any existing unit to hand
  • Mention any parking restrictions near the property
  • Let us know if the units are on a roof, a high wall or in a locked area

Ask for a quote

VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. To get one, give us a ring on 07833 053749 or drop us a line.

Advice

What happens if it’s left?

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 Colworth is done before the hot weather.

Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll explain each part.

Common questions in Colworth

Do you cover smaller places like Colworth?

Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.

Does being near the sea make a difference to air source heat pumps in Colworth?

It can, as Colworth is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.

Do you work on all makes?

We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.

Who has to arrange F-Gas leak checks?

Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

Will I get records for the system?

Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.

Is a heat pump permitted development?

In England, many air source heat pumps on houses can be permitted development, if the conditions are met. These include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), not being used solely for cooling and not being within the curtilage of a listed building.

Which type of heat pump is right for my home?

Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.

A customer’s words
