Heat pumps in Green Street Green: local notes

About 45% of homes in the Green Street Green area date from 1945 to 1972, according to VOA council tax data, and the 2021 Census found about 76% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.

For a home near Chelsfield station, the survey looks at whether an air-to-water or air-to-air heat pump suits better. Historic houses such as Down House, about 2.1 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.

Air source heat pumps in Green Street Green, done properly

Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. If the problem is questions about listed buildings or conservation areas and deciding on the outdoor unit position, we can sort it out.

Homes in Green Street Green are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and typically a hot water cylinder inside, while an air-to-air system needs less space.

Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

What owners can safely do

Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

What we do, step by step

You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Some blocks in Green Street Green need contractor details in advance, so tell us what your building needs.

  1. We talk through your home, your current heating and what you want from a heat pump.
  2. We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
  3. We send a fixed-price quote that shows the equipment, the grant position and the VAT.
  4. Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
  5. Commissioning, MCS certification and a handover of the controls finish the job.

Preparing for the visit

  • Tell us about parking and loading
  • Plan for pets to be kept clear during the visit
  • Clear the space around the indoor unit, or where it will go

Getting a quote

Some jobs can be priced from pictures, 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.

Green Street Green questions

Can you fit air conditioning in a London flat in Green Street Green?

In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.

Will a heat pump in Green Street Green need planning permission?

There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 10 buildings and structures within half a mile of the centre of Green Street Green. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Bromley council, which is typically the planning authority for Green Street Green.

Will you work on another installer’s system?

Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

Do you work on commercial properties?

Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.

Do you cover Green Street Green?

Yes. Green Street Green is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.

Whose job is it to check the system for leaks?

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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

Which type of heat pump is right for my home?

Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.

After we’ve gone

Looking after it is simple, and it helps at the next service:

  • Keep the MCS certificate with the manufacturer’s paperwork
  • Check what your manufacturer’s warranty asks of you
  • Find out the grant position at the survey

Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process since the grant goes through the installer.

Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.

What affects the cost of air source heat pumps

Our prices page gives typical ranges, and your quote is built on your job. The quote depends on:

  • What state the existing equipment is in
  • What kind of system it is
  • The size of the job

Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered and we’ll price it together.

What we need to know

When you contact us, it’s useful to have:

  • Where the property is and what kind of building it is
  • Wide photos of the room or the existing unit
  • A photo of the consumer unit with the cover closed

Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, ring us on 07833 053749.
