What to know about air-to-air heat pumps in Grantham
Most homes can run on a heat pump if the system is designed properly, and Grantham is no different. The key is matching the heat pump and radiators to the home's heat loss.
Extensions and garden rooms in Grantham that are hard to connect to the main heating can have their own air-to-air unit. For terraced homes in Grantham, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Rooms that get too hot in summer as well as cold in winter
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Outdoor unit and indoor units for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Top-floor rooms in Grantham that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Grantham quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Air-to-air heat pumps prices in Grantham
These are guide prices for Lincolnshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,400–£5,000 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
Short winter days in Grantham and what they mean
On the shortest day Grantham gets about 7 hours 35 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air-to-air heat pumps in Grantham: questions
How long does a heat pump survey take in Grantham?
A home survey in Grantham usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Sleaford as well as Grantham?
Yes. We arrange surveys and installation in Sleaford, which is about 11 miles north-east of Grantham, and across Lincolnshire.
Do I need new radiators for a heat pump in Grantham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Grantham home gives a room-by-room list.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies at survey.
How much sound do the indoor units make?
Indoor units are designed to run quietly, with a fan you will hear most when heating or cooling at full output. Lower fan settings and night modes reduce sound in bedrooms. Siting matters for the outdoor unit too: it needs airflow and a position that passes the MCS noise assessment. Ask to see the sound levels of the proposed units at survey.
