Air source heat pump installation for Haddington homes
Every property in Haddington is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Terraced streets in Haddington often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Edinburgh and the Lothians can arrange a survey in Haddington for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
What's included
- MCS registration and certificate, plus network operator notification
- Outdoor unit, hot water cylinder and weather compensation controls
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
- Commissioning, handover and a walk-through of the controls
In Haddington, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Haddington home, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Haddington property at survey.

Designing for Haddington's winters
Haddington has about 6 hours 57 minutes of daylight at midwinter against 17 hours 37 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.

Air source heat pump installation in Haddington: questions
Can you service a heat pump in Haddington that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Haddington, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Haddington?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Haddington home states the expected time.
What size heat pump does a Haddington 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 Haddington home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
