Is Your Home Right For A Heat Pump?

The honest answer depends on your specific home.

Most reasonably insulated Lothians homes with outdoor space and a cylinder location can run a heat pump comfortably. Here's the kind of property where it usually works well — and we'll give you a real answer on yours at the survey.

Best Fit

1960s-onwards semis and detached homes

Well-insulated family homes across the Lothians are the sweet spot for air source heat pumps. Most radiators can usually be reused after upsizing a few key rooms.

Great Fit

Modern and new-build properties

Homes built with cavity walls, good insulation, and larger radiators or underfloor heating are typically ready for a heat pump with minimal changes.

Viable With Planning

Older stone-built homes with insulation upgrades

Older Edinburgh and Midlothian properties can run a heat pump beautifully once fabric improvements are in place. We'll be honest about what to do first.

Usually Off-Grid Win

Properties currently on oil or LPG

Homes off the mains gas grid typically see the largest running cost savings from switching to a heat pump — and are often strong candidates for Home Energy Scotland grant and loan funding.

If your home is very draughty, has no room for a cylinder, or sits in a listed building with planning restrictions, we'll tell you straight. A high-efficiency gas boiler today, with a heat pump revisited after insulation upgrades, is often the more honest route — and it's exactly what we'd recommend for a friend or family member in the same position.

How We Work

From first survey to a warm home in four honest steps.

No pressure, no bait quotes, and no promises we can't keep on grants. Here's what actually happens when you book a heat pump project through Macara Heating.

01

Free home survey and heat loss calculation

We visit the property, measure each room, check the existing radiators, assess outdoor unit siting, and run a proper room-by-room heat loss calculation. You get a practical, honest view of whether a heat pump is the right call for your home.

Real survey, not an online estimate.

02

Fixed-price quote and Home Energy Scotland eligibility

You get a fixed written quote covering the heat pump, installation, cylinder, any radiator changes, MCS design, and commissioning. We'll review Home Energy Scotland grant and interest-free loan eligibility for your property and show you what the net cost looks like.

A fixed written quote, with a clear view of the net position.

03

MCS system design through JME Green Energy

Formal MCS system design, paperwork, and Home Energy Scotland application are handled under our partner JME Green Energy's MCS certification. You deal with one team, with a transparent paperwork trail from quote through to grant completion.

One team, one clear process, full MCS certification.

04

Installation, commissioning, and aftercare

Our Gas Safe engineers complete the install alongside JME, commission the system properly, tune the weather compensation, and walk you through the controls. You've got a local heating company to call if anything needs checking later.

Local engineers you can actually reach after the job.

Frequently Asked Questions

Heat pump questions, answered honestly.

Real answers to the questions we get asked most by Edinburgh and Lothians homeowners thinking about an air source heat pump.

How much does an air source heat pump cost in Edinburgh?

Most domestic air source heat pump installations in Edinburgh and the Lothians land between £10,000 and £16,000 before any grant or loan funding. The final price depends on the property size, heat loss, how much radiator or pipework upgrade is needed, and the system design. Because installs are completed under our partner JME Green Energy's MCS certification, eligible Scottish homeowners can access Home Energy Scotland funding — a grant toward the install plus an interest-free loan on top. We'll confirm eligibility and current amounts at the survey.

Will a heat pump actually keep my home warm in a Scottish winter?

Yes — when the system is properly sized and designed for the property. A modern air source heat pump works fine at outside temperatures well below freezing, which is more than Edinburgh usually throws at one. The part that matters isn't the heat pump brand, it's whether the system has been designed for your home's actual heat loss, and whether the radiators or underfloor heating can deliver that heat at the lower flow temperatures heat pumps run at. That's why the survey matters.

Do I need to replace my radiators for a heat pump?

Sometimes, but not always. Heat pumps run at lower flow temperatures than gas boilers, so existing radiators need to be large enough to deliver the same heat at a lower temperature. During the survey we measure each room's heat loss and check the existing radiators — often a handful of rooms need larger radiators, while the rest of the system can stay. We'll never quote radiator changes you don't need.

Are air source heat pumps noisy?

Modern air source heat pumps are quieter than most people expect — usually around 40-45 decibels at close range, which is roughly the level of a quiet conversation. Siting matters: we position the outdoor unit so it doesn't sit directly under a bedroom window or bounce sound off a neighbouring wall, and the MCS installation standards include noise assessment as part of sign-off.

Do I need planning permission for an air source heat pump in Scotland?

Often no, but not always. Air source heat pumps commonly fall under permitted development in Scotland, which means a separate planning application is not always needed. There are exceptions though — for example listed buildings, some constrained sites, and certain siting or height issues. We check the property properly at survey rather than giving a blanket yes or no.

How does the Home Energy Scotland grant and loan work for a heat pump?

Scottish homeowners access heat pump funding through Home Energy Scotland, not the Boiler Upgrade Scheme (which is England and Wales only). HES offers a grant toward an MCS-certified heat pump install, plus an interest-free loan on top for remaining costs. Rural and island properties may qualify for an uplift. Because our heat pump installs are completed under the MCS certification of our partner JME Green Energy, eligible homes can use the HES grant and loan through them — we support the paperwork alongside JME as part of the install.

Heat pump or new gas boiler — which is right for my home?

Both are valid, and we install both, so we've no reason to push you toward one over the other. A new gas boiler is usually cheaper upfront and a better fit for homes that aren't ready for radiator upgrades or fabric improvements. A heat pump usually has lower running costs long-term, can qualify for Home Energy Scotland grant and interest-free loan funding, and is the right call for anyone planning to stay in the home for years and move away from fossil fuels. The honest answer depends on your home, your timeline, and your budget — which is what the survey is for.

How long does an air source heat pump installation take?

Most domestic air source heat pump installations take between three and five working days on site, depending on whether radiators need upgrading, whether the hot water cylinder is being replaced, and the complexity of the pipework. The full project — from first survey through commissioning and Home Energy Scotland paperwork — usually runs four to eight weeks once you decide to go ahead.

Who actually designs and installs the heat pump?

Heat pump installs are delivered jointly by Macara Heating and our MCS-certified partner JME Green Energy. Macara Heating is the local, Gas Safe registered heating team you deal with on the ground. JME Green Energy holds the MCS certification required for Home Energy Scotland grant and loan funding and for the formal system design sign-off. That partnership is how Scottish homeowners get Home Energy Scotland eligibility through us — it's completely transparent and it's how the funding paperwork is meant to work.

What kinds of homes are heat pumps suitable for?

Air source heat pumps suit most reasonably insulated homes with space for an outdoor unit and space for a hot water cylinder indoors. They work well in 1960s-onwards semis, detached houses, modern builds, and increasingly in well-insulated older properties. They can be harder to justify in very small flats with no outdoor space, heritage properties with planning restrictions, or very draughty uninsulated homes where the running costs won't work out. Every property is different — the survey is the honest way to find out.

Can you put a heat pump in an older stone house in Scotland?

Often yes, but the answer depends on the condition of the house rather than the age on paper. Older stone-built homes can run a heat pump well if the heat loss is understood properly and the system is designed around it. The survey matters more here than on a newer house, because insulation levels, draughts, radiator sizes, and cylinder space vary a lot from one property to the next.
