Air source heat pumps in Sidlesham, done properly
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Sizing by rule of thumb isn’t good enough. The work covers homes heated by oil, LPG or gas, hot water cylinders and underfloor heating, and people most often call us about choosing between air-to-water and air-to-air and replacing a combi boiler with a heat pump.
Homes around Sidlesham typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we’re called out for in Sidlesham
Many enquiries start with a question about the Boiler Upgrade Scheme. Eligibility depends on the property, the system and the scheme rules, so we check before you commit.
Any of these is worth a proper look:
- Working out where a cylinder could go
- Questions about the Boiler Upgrade Scheme
- Checking emitters for a heat pump
Period properties close to St Mary Our Lady Sidlesham can suit a heat pump, though insulation and any heritage protection are checked first.

Keeping the system healthy
Aftercare is straightforward, and it makes the next visit easier:
- Let the heat pump run steadily, as set up at handover
- Leave space around the outdoor unit
- Find out the grant position at the survey
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside, so keep it clear all year.

What happens on the day
If the system has to be off for part of the visit, we tell you before work begins so it does not catch you out. In a business, work can often be done one area at a time. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We agree a date with you and plan the visit to Sidlesham so we arrive with what’s needed.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.

How to prepare

- Let us know where we can park and unload

Air source heat pumps around Sidlesham
Sidlesham lies within about 1 mile of the sea. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. About 56% of homes in Sidlesham and the neighbourhoods around it date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 72% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Houses normally have space for an outdoor unit and a hot water cylinder. There are 2 conservation areas within a mile of the centre of Sidlesham. About 7 listed entries lie within half a mile of central Sidlesham, The Parish Church of St Mary (grade I) among them. 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 Chichester council, which usually handles Sidlesham where necessary.
Every heat pump design starts with a room-by-room heat loss calculation.

Sidlesham: your questions answered
Is Sidlesham 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 Sidlesham?
Yes, the scheme covers homes in England, including Sidlesham, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Should I choose air-to-water or air-to-air?
It depends on your home, your heating and whether you want cooling. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally 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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Do I get paperwork after the visit?
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.
