Air source heat pumps for Barnsbury

Air source heat pumps in Barnsbury

In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. If you are dealing with replacing a combi boiler with a heat pump and comparing heat pump types, we can help.

In a London area like Barnsbury, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and typically a hot water cylinder inside, while air-to-air units take less room.

Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Common problems we fix in Barnsbury

The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.

Common reasons people call us are:

  • Moving away from fossil-fuel heating
  • Deciding on the outdoor unit position
  • A boiler that’s getting old

If your home is near Caledonian Road & Barnsbury station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

Common questions in Barnsbury

Does the Boiler Upgrade Scheme cover homes in Barnsbury?

Barnsbury is covered, as the scheme runs across England and Wales. 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 is not an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.

Do I need permission to put air conditioning in my flat in Barnsbury?

Often, yes, but the lease and the freeholder usually have a say. 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.

Who is responsible for leak checks?

The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.

Can I do the refrigerant work myself?

The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.

How quickly will you reply?

The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.

Is there a survey before the work?

Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.

Do you offer maintenance contracts?

Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.

Air source heat pumps in Barnsbury: the local picture

About 39% of homes across Barnsbury and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 84% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. A flat may have no room for a hot water cylinder, and the freeholder normally has a say on the outdoor unit, which can tip the choice towards air-to-air. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.

Dr Johnson's House, roughly 2.1 miles south, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

What affects the cost of air source heat pumps

The survey or diagnosis tells us what the work involves. The main factors are:

  • What we find on the survey or diagnosis
  • The pipe route between the units
  • The type of system, from a single split to a larger system

Typical ranges are on our prices page, but each job is priced on what it involves. For a fixed-price quote, ring us on 07833 053749 or drop us a line, and we’ll explain what it covers.

Before you get in touch

A few details help us quote accurately. With your enquiry, please include:

  • Any error code or flashing light on the display
  • Your consumer unit or fuse board
  • The postcode and whether it’s a home, flat or business

Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, ring 07833 053749 or fill in the contact form.

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. At the end, we tidy up and run through the work with you. Parking bays, permits and roof or balcony access are the first things we ask about in Barnsbury.

  1. We talk through your home, your current heating and what you want from a heat pump.
  2. A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
  3. You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
  4. The outdoor unit, the indoor equipment and the controls are installed and connected.
  5. We commission the heat pump, complete the MCS paperwork and talk you through the controls.

Getting ready for the visit

  • Make sure we can reach the outdoor unit, or where it will go
  • Make sure we can reach the consumer unit or fuse board
  • Have the make and model of any existing unit to hand

Ask for a quote

Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, give us a ring on 07833 053749 or use the quote form.
