Air source heat pumps across Guildford

Air source heat pumps in Guildford

Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers homes heated by oil, LPG or gas, underfloor heating and air-to-water heat pumps, and common reasons people get in touch are an oil, LPG or gas boiler near the end of its life and checking emitters for a heat pump.

In Guildford, an air-to-water system takes over from the boiler for heating and hot water, with £7,500 off through the Boiler Upgrade Scheme where the home qualifies.

Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

How it works

The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes a few days for most air-to-water installations, with air-to-air systems often quicker. The more we can see beforehand, the smoother the visit to Guildford will be.

  1. You tell us about the home and what you want from a heat pump.
  2. The survey checks heat loss, emitters, hot water and the outdoor unit position.
  3. You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
  4. We install the heat pump and connect it up.
  5. The job ends with commissioning, the MCS certificate and a walk through the controls.

Getting ready for the visit

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Arrange for someone to be there to let us in
  • Have the make and model of any existing unit to hand

How to get a quote

Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, phone us on 07833 053749, or email if that’s easier.

Different systems, different jobs

Air-to-air heat pumps

The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It also has to be fitted by an MCS certified installer, in a home.

The Boiler Upgrade Scheme

Not every home qualifies and we confirm it before anything is agreed.

Managing agents and facilities teams in Guildford

For anyone managing more than one building, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.

Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we’ll copy in whoever needs it.

When something else is needed

Before booking, it helps to know what’s not included:

  • Disconnecting or servicing a gas boiler
  • Tax advice on your own circumstances
  • Promising eligibility for the Boiler Upgrade Scheme

Not sure which it is? You can give us a ring on 07833 053749 or use the quote form and we’ll tell you honestly before you book.

What the work covers

  • Air-to-water heat pumps
  • Hot water cylinders
  • Underfloor heating
  • Radiator systems
  • Homes heated by oil, LPG or gas
  • Air-to-air heat pumps

Air source heat pumps in Guildford: the local picture

The 2021 Census found about 46% of households live in flats. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better.

Older homes near Church of St John the Evangelist may need extra checks for planning and heat loss before a heat pump is designed. Guildford Castle lies about 0.9 miles south. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Guildford is about 27 miles south-west of London, in Surrey. Guildford 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. Guildford is one of 395 towns, villages and districts in Surrey we cover.

A recent job of ours in Guildford was on Stoughton Road (GU2): installing a Mitsubishi Electric wall-mounted unit in the living room and a second unit in the master bedroom.

With the A3 and A25 close by, Guildford is easy for our engineers to reach for visits of every kind. Postcode districts we cover here: GU1, GU2, GU4 and GU3. If you are just outside Guildford, we cover Bellfields (1 mile north), Abbotswood (1 mile south-east), Stoughton (1 mile north-west), Westborough (1 mile west) and Burpham (1 mile north-east). We also work in nearby towns such as Woking (5 miles north), Camberley (9 miles north-west), Epsom (15 miles north-east) and Farnham (10 miles west).

Near you in Guildford

Locally, jobs take us to houses, flats and workplaces close to The King's Head pub, Guildford High School and Surrey Maths School, among other places. Guildford’s nearest station is London Road (Guildford) station, roughly 0.6 miles south-east of the centre. Well-known places in the area include Guildford Castle (0.9 miles south) and Guildford House (0.8 miles south). Green spaces nearby include Silent Pool and Pewley Hill.

Common questions in Guildford

Does the Boiler Upgrade Scheme cover homes in Guildford?

Yes, the scheme covers homes in England, including Guildford, if they qualify. 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. The installer applies, and we’re MCS certified.

Is planning permission needed for a heat pump in Guildford?

That depends on the building and where the outdoor unit goes. The Wey and Godalming Navigations Conservation Area is close to the centre of Guildford. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Guildford council, typically the authority for Guildford.

How long will it take to install a heat pump?

The work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The survey lets us set a firm programme, and you can ring 07833 053749 or email us to book it.

Whose job is it to check the system for leaks?

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 will work out which band applies to yours.

Why use an F-Gas certified company?

F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and we hold it.

Can landlords and managing agents book you?

Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Guildford and across Surrey. Let us know who the records should go to.

Will my radiators work with a heat pump?

We find out during the survey. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.

From one of our customers

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
