Air source heat pumps in Thundersley
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. Common call-outs are for plans to switch to electric heating with a heat pump and questions about listed buildings or conservation areas, on radiator systems, air-to-water heat pumps and homes heated by oil, LPG or gas.
Around Thundersley, most people asking about heat pumps have a gas boiler now. A survey looks at heat loss, radiators, the hot water cylinder and where the outdoor unit can go, then design the system.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

How it works
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Shops and offices in Thundersley can usually stay open while we work, or we come after hours.
- 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.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Plan for pets to be kept clear during the visit
- Mention any parking restrictions near the property
How to get a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Heat pumps in Thundersley: local notes
Valuation Office Agency council tax records date about 55% of homes in the Thundersley area to the post-war years, 1945 to 1972, and the 2021 Census found about 87% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Questions from Thundersley
Is a heat pump in Thundersley permitted development?
It depends on the property. Historic England lists about 3 buildings and structures within half a mile of the centre of Thundersley. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Castle Point council, typically the authority for Thundersley.
Can I get the Boiler Upgrade Scheme grant in Thundersley?
Thundersley is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we’re MCS certified.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Does servicing affect my warranty?
It depends on 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.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
What affects the quote in Thundersley
Before we fix a price, we need to know a few things. We look at:
- Whether it’s a one-off job or part of a maintenance contract
- The equipment or parts the job needs
- The electrical supply and whether a new circuit is needed
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the property is and what kind of building it is
- Wide photos of the room or the existing unit
- A close-up of the unit’s label showing the model number
If you need air source heat pumps in Thundersley, ring us on 07833 053749 or drop us a line. Let us know the type of property and what you need, plus some pictures if they’re to hand. We reply the same working day.
Signs you need air source heat pumps in Thundersley
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
The things we’re asked about most include:
- An oil, LPG or gas boiler near the end of its life
- Questions about where the outdoor unit can go
- Checking whether planning permission is needed
Live in one of the older houses around Church of St Peter? Expect the survey to look closely at heat loss and at the building’s planning status.
Before you book anyone
- Whether you get F-Gas records where refrigerant is involved
- Whether testing, commissioning and paperwork are included
- Whether the manufacturer’s warranty depends on regular servicing
Aftercare tips
How well a system lasts depends on use and care. Here’s what we suggest:
- Do not block radiators or indoor units with furniture
- Avoid switching the heat pump on and off often
- Store the MCS certificate and warranty documents together
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes, and that’s normal.
Have the system serviced regularly. Your manufacturer’s warranty terms may say something about servicing.
