What happens on the day
We book the visit for a day and time that suit 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 anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Rural lanes and tight entrances are worth mentioning before a visit to Avisford.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the outdoor unit, or where it will go
- Make sure someone can let us in at the agreed time
Getting a quote
For a fixed-price quote, call 07833 053749 or email us and tell us about the property and what you need. A few pictures make it quicker. You will hear back from us the same working day.
Advice
Air source heat pumps in Avisford
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. Typical jobs include a boiler that’s getting old and plans to switch to electric heating with a heat pump, across hot water cylinders, air-to-water heat pumps and radiator systems.
Older and listed homes in villages like Avisford need extra care, and permitted development does not cover listed buildings, so we check consent first.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

What a heat pump looks like in Avisford
On the National Heritage List, around 25 entries fall within 0.5 miles of the middle of Avisford; The Parish Church of St Mary (grade I) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the planning team at Arun council, which usually handles Avisford. About 35% of homes in Avisford and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 71% of households in detached or semi-detached houses. Newer homes normally lose less heat, which tends to suit a heat pump well. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
A heat loss calculation decides the size of heat pump your home needs. Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.

Your questions about air source heat pumps in Avisford
Is the heat pump grant available in Avisford?
Avisford is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You do not apply yourself: the MCS certified installer does, which is us.
Is Avisford within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What does an air-to-water heat pump cost?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. Your price depends on the survey, the emitters and the hot water, and you get a fixed-price quote.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you look at the job first?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
Before you call an engineer
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and give us a ring on 07833 053749 or fill in the contact form.
After we’ve gone
Once we have finished, these simple steps help:
- Know the servicing conditions in your warranty
- Leave space around the outdoor unit
- Keep up with insulation and draught-proofing
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.
Have the system serviced regularly. Your manufacturer’s warranty terms may say something about servicing.

Why act early in Avisford
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 Avisford is done before the hot weather.
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.

“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.”
