FAQs for Higher Denham
Is Higher Denham within the area you cover?
Yes. Higher Denham is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Higher Denham?
Yes, if the home and the heat pump meet the scheme’s rules: Higher Denham is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do I need planning permission for a heat pump?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter, so we check for your property.
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. Keep every service record either way.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Do I need new radiators for a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.
About our air source heat pumps in Higher Denham
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 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. We’re often asked to deal with questions about the Boiler Upgrade Scheme and ageing boilers that will need replacing, across homes heated by oil, LPG or gas, hot water cylinders and underfloor heating.
If your home in or near Higher Denham is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. 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. Seeing the property in pictures first means the trip to Higher Denham can be planned properly.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
Before we arrive
- Have the make and model of any existing unit to hand
- Keep pets and children away from the work area
- Make sure we can reach the outdoor unit, or where it will go

Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
Hot water cylinders
Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.

What affects the cost of air source heat pumps
Every job gets its own quote. This is what makes a difference:
- What we find on the survey or diagnosis
- The size of the job
- Which make and model is being fitted or worked on
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. You will have a fixed price before any work starts, with VAT shown clearly.
Before you get in touch
Good pictures often save a visit. Try to include:
- A few pictures of the room and the wall the unit is on, or will go on
- Any error code or flashing light on the display
- A close-up of the unit’s label showing the model number
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, the quote is fixed before anything goes ahead.
