Before you book: replacing a gas boiler with a heat pump in Musselburgh
In Musselburgh, 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.
Rear gardens and side returns in Musselburgh usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. If your Musselburgh home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.
- System or regular boiler homes with an existing airing cupboard
- Households ready to give up gas entirely and drop the standing charge
- Boilers that are old, unreliable or due for replacement
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- Capping of the gas pipe at the boiler position where you are giving up gas
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
Many gas-heated homes in Musselburgh have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Musselburgh can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
Gas boiler to heat pump costs around Musselburgh
The ranges below are typical installed prices for homes in Edinburgh and the Lothians, including VAT. A survey sets the exact figure, because two similar-looking houses in Musselburgh can need quite different radiators and pipework.
| Home | Typical size | Installed guide price |
|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,700–£12,750 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,700–£13,750 |
| 3 bedroom semi or small detached | 6–9 kW | £12,250–£15,800 |

| 5+ bedroom or larger older house | 11–16 kW | £16,850–£22,950 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. In Scotland, Home Energy Scotland grants of up to £7,500 and interest-free loans may reduce the cost.
Short winter days in Musselburgh and what they mean
On the shortest day Musselburgh gets only about 6 hours 57 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Replacing a gas boiler with a heat pump in Musselburgh: questions
Where would the outdoor unit go on a Musselburgh house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Musselburgh home.
How soon can you survey a home in Musselburgh?
Survey dates depend on how busy installers are in Edinburgh and the Lothians. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Musselburgh that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Musselburgh, whoever fitted them. Tell us the make and model when you book.
Can a heat pump replace a combi boiler?
Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
