Air source heat pumps in Theydon Garnon
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers underfloor heating, air-to-air heat pumps and radiator systems, and people most often call us about checking emitters for a heat pump and checking eligibility for a heat pump grant.
Older and listed homes in villages like Theydon Garnon need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Looking after it afterwards
Once we have finished, these simple steps help:
- Look at insulation alongside the heat pump
- Use the settings explained at handover
- Keep to regular servicing
After commissioning, the installation is registered under MCS and you receive the certificate. File it with the warranty documents, as you may need it later.
Do not cover radiators with furniture or heavy curtains so the heat can get into the room.
The process
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. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. We plan the trip to Theydon Garnon around you.
- You tell us about the home and what you want from a heat pump.
- 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.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Clear a path to the units and the space around them
- Name a contact who can meet us at the agreed time
- Plan for pets to be kept clear during the visit

Theydon Garnon questions
Will a heat pump in Theydon Garnon need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Theydon Garnon holds about 15 listed buildings and structures. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Epping Forest council, usually the authority for Theydon Garnon.
Will you come out to Theydon Garnon?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Does the grant cover air-to-air heat pumps?
Sometimes, and the amount is £2,500 rather than £7,500. The system has to replace the fossil-fuel heating and heat the whole home, installed by an MCS certified installer.
Are my radiators big enough for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Are you F-Gas certified?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
How quickly will you reply?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source, and we explain which suits your home.
What affects the cost of air source heat pumps
We quote each job individually. These are the things that affect it:
- How easy the units are to reach
- The type of system, from a single split to a larger system
- What electrical work the job needs
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Your consumer unit or fuse board
- The make and model of the system, from the label
- A few photos of the room and the wall the unit is on, or will go on
