Air-to-air heat pumps in Grimsby: what to expect
In Grimsby, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Grimsby that overheat in summer gain from the cooling an air-to-air system provides. Installers in Grimsby plan condensate drains and pipe covers so indoor and outdoor runs stay neat.
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.
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
- Flats and apartments with storage or panel heaters
What's included
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
Flats in Grimsby on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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 Grimsby 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 Grimsby
Guide prices for Grimsby and the rest of Lincolnshire are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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.
How long is the heating season in Grimsby?
Grimsby sees roughly 7 hours 27 minutes of daylight in December and 17 hours 03 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.
How installation works in Grimsby
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Grimsby; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Grimsby: questions
Do you cover Cleethorpes as well as Grimsby?
Yes. We arrange surveys and installation in Cleethorpes, which is about 2 miles east of Grimsby, and across Lincolnshire.
What size heat pump does a Grimsby home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Grimsby home.
How long does a heat pump survey take in Grimsby?
A home survey in Grimsby 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.
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.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
