Before you book: air-to-air heat pumps in Hemel Hempstead
The question for a Hemel Hempstead home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Extensions and garden rooms in Hemel Hempstead that are hard to connect to the main heating can have their own air-to-air unit. Installers in Hemel Hempstead 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.
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- 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
- Condensate drains and neat external pipe covers
For terraced homes in Hemel Hempstead, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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 Hemel Hempstead 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.
What to budget for air-to-air heat pumps in Hemel Hempstead
The ranges below are typical installed prices for homes in Hertfordshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Hemel Hempstead can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,500–£5,250 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,200–£8,400 |
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 Hemel Hempstead?
Hemel Hempstead has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air-to-air heat pumps in Hemel Hempstead: questions
How long does installation take in Hemel Hempstead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hemel Hempstead home states the expected time.
How soon can you survey a home in Hemel Hempstead?
Survey dates depend on how busy installers are in Hertfordshire. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Hemel Hempstead that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hemel Hempstead, whoever fitted them. Tell us the make and model when you book.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
