Air source heat pumps across Crooked Billet

Air source heat pumps in Crooked Billet

For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. The work covers underfloor heating, air-to-water heat pumps and hot water cylinders, and common reasons people get in touch are not knowing whether a grant applies and working out whether radiators need upsizing.

In a London area like Crooked Billet, many homes are flats or terraces with little outside space, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Pricing air source heat pumps in Crooked Billet

The quote reflects the job in front of us. We consider:

  • One-off work versus a regular service cycle
  • What state the existing equipment is in
  • The size of the job

What you pay depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before we start, so you know where you stand.

Asking for a quote

Before you ask for a quote, gather:

  • A short video of any fault, such as a noise or a flashing light
  • The make and model of the system, from the label
  • Photos showing the indoor unit and the space around it

For a fixed-price quote, call us on 07833 053749 or write to us at info@aircondoctor.co.uk and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.

Questions from Crooked Billet

Do I need planning permission for a heat pump in Crooked Billet?

It depends on the property. The centre of Crooked Billet is in the Wimbledon West Conservation Area. 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 Merton council, which is usually the planning authority for Crooked Billet.

Can I have air conditioning in a flat in Crooked Billet?

Normally, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.

Can we book visits on a schedule?

Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.

Who is responsible for leak checks?

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.

Are my radiators big enough for a heat pump?

It varies from room to room. We check them all during the survey, so the quote covers any changes.

Will I get records for the system?

Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

How do you keep the place clean during the work?

Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.

Signs you need air source heat pumps in Crooked Billet

People also ask about air-to-air heat pumps because they heat and cool. They heat rooms through wall, floor or ceiling units and switch to cooling in warm weather. Whether a grant applies depends on the scheme conditions.

Look out for any of the following:

  • Moving away from fossil-fuel heating
  • Checking whether planning permission is needed
  • Checking emitters for a heat pump

Live in one of the older houses around Christ Church? Expect the survey to look closely at heat loss and at the building’s planning status.

What your quote should include

  • Whether they hold F-Gas company certification, not just individual qualifications
  • What happens if the job turns out to be different on the day
  • Whose warranty applies, and on what terms

Choosing an air con installer

Heat pumps in Crooked Billet: local notes

Census 2021 figures found about 45% of households live in flats. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.

Historic houses such as Southside House, about 0.5 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.

Crooked Billet is about 1 mile west of Wimbledon, in Greater London. Crooked Billet gets the same approach as every job we take on: a look at the job first, a fixed-price quote and written records at the end. In Greater London alone we list 764 places, and Crooked Billet is one. For properties nearby, see our Croydon page (7 miles or so).

Not far from Crooked Billet, a recent job of ours was on Parkside, Wimbledon (SW19), about 1 mile east: installing a Mitsubishi Electric multi-split system serving four bedrooms and the main living room.

How it works

If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. If a freeholder or agent needs to agree the work in Crooked Billet, we can send them the details.

  1. Step one is understanding the house, how it’s heated today and what you’d like to change.
  2. The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
  3. A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
  4. Installation covers the outdoor unit, the indoor connections and the controls.
  5. We commission the heat pump, complete the MCS paperwork and talk you through the controls.

Before we arrive

  • Keep pets and children away from the work area
  • Make sure we can reach the outdoor unit, or where it will go
  • Let us know if the building has a permit or sign-in process

Getting a quote

Here’s what helps us quote: the address and the type of property, a few photos, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, give us a ring on 07833 053749 or send an email.
