What we’re called out for in Hadleigh
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
Most people get in touch when they notice something like this:
- Deciding which kind of heat pump suits the home
- Questions about where the outdoor unit can go
- Moving away from fossil-fuel heating
Live in one of the older houses around Church of St James the Less? Expect the survey to look closely at heat loss and at the building’s planning status.

Air source heat pumps for homes and businesses in Hadleigh
In England, an air source heat pump on a house can often go in under permitted development rights. 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. Common call-outs are for radiators that may be too small for a heat pump and ageing boilers that will need replacing, across homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps.
For a house near Hadleigh, space outside is rarely the problem, so the main questions are heat loss, radiators and the electrics.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Aftercare tips
How well a system lasts depends on use and care. We suggest:
- Store the MCS certificate and warranty documents together
- Leave indoor units unobstructed
- Keep to regular servicing
Once commissioned, we register the installation with MCS and give you the certificate. File it with the warranty documents, as you may need it later.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
FAQs for Hadleigh
Can I get the Boiler Upgrade Scheme grant in Hadleigh?
Yes, the scheme covers homes in England, including Hadleigh, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we’re MCS certified.
Do you cover smaller places like Hadleigh?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
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 yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Do I need planning permission for a heat pump?
In England, many air source heat pumps on houses can be permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Air source heat pumps around Hadleigh
The coast is only about 2 miles from Hadleigh. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. VOA council tax data date about 48% of homes in and around Hadleigh to the post-war years, 1945 to 1972, and the 2021 Census found about 77% 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. Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as Church of St James the Less (grade I). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
A heat loss calculation decides the size of heat pump your home needs.

Other services in Hadleigh
Owner checks or an engineer?
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, 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. We load the van from the survey notes so the work in Hadleigh can be done in one go where possible.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Tell us about parking and loading
- Make sure someone can let us in at the agreed time
Getting a quote
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
