Air source heat pumps for Nether Street

Air source heat pumps in Nether Street

Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you will need another way to do that. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps, and people most often call us about working out where a cylinder could go and wanting to stop using oil, LPG or gas for heating.

Space for an outdoor unit is rarely an issue near Nether Street, so the design focuses on heat loss and radiators.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Why act early in Nether Street

A sudden boiler failure rarely leaves room to plan a heat pump properly. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. A system that is left with a fault, or without a service, normally costs more to run.

Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account, and the price is fixed before work begins.

Before you call an engineer

Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.

Before you call us about a fault, a few checks can save a visit: 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 phone 07833 053749 or send an email.

FAQs for Nether Street

Is Nether Street within the area you cover?

Yes. Nether Street is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.

Does the Boiler Upgrade Scheme cover homes in Nether Street?

Yes, if the home and the heat pump meet the scheme’s rules: Nether Street is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.

Can I do any of the installation myself?

No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.

Whose job is it to check the system for leaks?

Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.

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.

Do you survey before quoting?

Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.

How soon will you get back to me?

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

Pricing air source heat pumps in Nether Street

Every job gets its own quote. This is what makes a difference:

  • How easy the units are to reach
  • What we find on the survey or diagnosis
  • How far the pipework has to run, and where

No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.

Before you get in touch

A few details help us quote accurately. When you get in touch, it helps to send:

  • Any previous service or F-Gas records
  • Photos showing the indoor unit and the space around it
  • A close-up of the unit’s label showing the model number

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

How it works

On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself 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 photos first means the trip to Nether Street can be planned properly.

  1. We start with your plans and the property.
  2. The survey checks heat loss, emitters, hot water and the outdoor unit position.
  3. We explain which type of heat pump suits the home and whether a grant could apply.
  4. The system is installed and connected to the controls.
  5. We commission it, complete the MCS certificate and show you how to use it.

Before we arrive

  • Let us know if the units are on a roof, a high wall or in a locked area
  • Keep pets out of the rooms we are working in
  • Tell us about parking and loading

Getting a price

Some jobs can be priced from photos, 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, the quote is fixed before anything goes ahead.

Advice

What a heat pump looks like in Nether Street

The 2021 Census found about 74% of households in detached or semi-detached houses. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. Nether Street’s centre falls inside the Widford Conservation Area. On the National Heritage List, around 37 entries fall within 0.5 miles of the middle of Nether Street; Nether Hall (grade II) is one. Where a home is affected, the outdoor unit position is settled with the planning team at East Hertfordshire council, which normally handles Nether Street before the heat pump design is finished.

If your home is one of the older properties near Parish Church of St John the Baptist, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. With Much Hadham Palace about 2.3 miles north, it’s worth asking whether your own home is listed before planning a heat pump.
