About our air source heat pumps in Flacks Green
We install air source heat pumps in Flacks Green and across Essex, and we’re MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We’ll explain which type fits your home and why. Typical jobs include comparing heat pump types and moving away from fossil-fuel heating, across underfloor heating, air-to-water heat pumps and air-to-air heat pumps.
For a home around Flacks Green that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Heat pumps in Flacks Green: local notes
The 2021 Census found about 79% of households in detached or semi-detached houses. 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. Period properties close to United Reformed Church can suit a heat pump, though insulation and any heritage protection are checked first.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Don’t block radiators or indoor units with furniture
- Keep to regular servicing
- Leave space around the outdoor unit
Equipment warranties come from the manufacturer. We go through the conditions with you, including any servicing they ask for.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
Common questions in Flacks Green
Do you cover smaller places like Flacks Green?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Will a heat pump in Flacks Green need planning permission?
It depends on the property. The centre of Flacks Green is in the Terling Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the planning department at Braintree council, usually the authority for Flacks Green first.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.

Leave it or put it right?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. Checking and upsizing them as part of the installation avoids that. Getting the date in early helps for a place like Flacks Green.

How the job changes from property to property
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. Cooling-only units are not included and need a check with the council.
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, so radiator sizes matter.
