The process
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it 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 West Thorney.
- We find out about your home and the heating you have now.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Clear a path to the units and the space around them
- Plan for pets to be kept clear during the visit
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

Air source heat pumps in West Thorney, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers radiator systems, air-to-water heat pumps and air-to-air heat pumps, and common reasons people get in touch are planning and permitted development questions and choosing between air-to-water and air-to-air.
Space for an outdoor unit is rarely an issue near West Thorney, so the design comes down to heat loss, radiators and hot water.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or drop us a line.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
How we price air source heat pumps
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- Whether it’s a simple split or a larger system
- The equipment or parts the job needs
- How many units are involved
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before work begins.
Helping us quote
You don’t need the technical terms. Just send:
- A short video of any fault, such as a noise or a flashing light
- The postcode and whether it’s a home, flat or business
- Your consumer unit or fuse board

Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we’ll explain the settings for your home.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
What a heat pump looks like in West Thorney
The coast is only about 1 mile from West Thorney. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. About 70% of households live in detached or semi-detached houses, according to the last census (2021). Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Period properties close to The Parish Church of St Nicholas can suit a heat pump, though insulation and any heritage protection are checked first. Historic houses such as Warblington Castle, about 3.1 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.

West Thorney questions
Can I get the Boiler Upgrade Scheme grant in West Thorney?
West Thorney 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 don’t apply yourself: the MCS certified installer does, which is us.
Is the coast a problem for outdoor units in West Thorney?
It can, as West Thorney is within about 1 mile 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.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
How long will it take to install a heat pump?
An installation 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. The survey lets us set a firm programme, and you can phone us on 07833 053749 or send an email to book it.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.

“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.”
