About our air source heat pumps in Upper Hartfield
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 cannot 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 air-to-water heat pumps, homes heated by oil, LPG or gas and radiator systems, and common reasons people get in touch are checking whether planning permission is needed and choosing between air-to-water and air-to-air.
Space for an outdoor unit is rarely an issue near Upper Hartfield, 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’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

What a heat pump looks like in Upper Hartfield
At about 29 miles from central London, Upper Hartfield sits inside the area we cover across London and the South East. About 74% of households live in detached or semi-detached houses, according to the last census (2021). Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
With Bassetts Manor about 1.9 miles north, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near Holy Trinity Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Upper Hartfield: your questions answered
Does the Boiler Upgrade Scheme cover homes in Upper Hartfield?
Upper Hartfield is in England, where the Boiler Upgrade Scheme runs. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Can you do air source heat pumps in Upper Hartfield?
Yes, Upper Hartfield is within the area we cover. Get in touch with the details and we reply the same working day.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
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.
The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. 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. A few photos help us make the most of a visit to Upper Hartfield.
- 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.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Name a contact who can meet us at the agreed time
- Make sure we can reach the consumer unit or fuse board

Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

How the job changes from property to property
Heat loss surveys
We look at walls, windows, floors, roofs and ventilation, and the size of each room.
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go particularly in homes with a combi boiler.
Safe owner checks
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Planning approval where permitted development does not apply
- Insulation work, such as loft or cavity wall insulation
- Tax advice on your own circumstances
If in doubt, call us on 07833 053749 or fill in the contact form and we will say what we think before you book.
