Heat Pump Installation in Lasswade
Engineer-led heat pump installs across Lasswade, Bonnyrigg and Polton, delivered in partnership with JME Green Energy under their MCS certification.
Macara Heating installs air source heat pumps across Lasswade, Bonnyrigg and Polton — a strong belt of mid-twentieth-century and modern detached and semi-detached housing in central Midlothian. The housing stock here is well suited to a heat pump conversion: good fabric, proper gardens for outdoor siting, generous radiator runs on the larger homes, and a chunk of properties where the long-term running-cost savings against a gas boiler make the numbers work clearly. Every MCS installation is delivered in partnership with JME Green Energy so eligible properties can access Home Energy Scotland grant and interest-free loan funding. We're based in Danderhall — about fifteen minutes from most of this area.
Local Context
Lasswade village sits along the North Esk valley with a mix of older stone and Victorian properties in the village core and larger modern detached on the surrounding roads. The older stone properties in the village centre carry some conservation sensitivity — Lasswade has historically significant buildings around the church and the river crossing — so outdoor unit siting on the tighter village-core plots needs thought. The modern detached and semi-detached stock around the village edges and along the roads toward Bonnyrigg is much more straightforward: good fabric, proper gardens, permitted development in almost every case.
Bonnyrigg's housing stock is one of the broadest spreads in Midlothian. The town covers everything from inter-war and post-war council-built terraces and semis in the older parts of town through to 1970s and 1980s detached on the outer streets and substantial newer estates on the eastern and southern edges. The strongest heat pump candidates are the larger detached homes — three and four bedrooms, proper gardens, solid construction, the kind of heating demand that justifies a well-sized system. The mid-range semis are viable too, especially the ones with reasonable garden space and fabric that's been upgraded over the years. We'll tell you honestly on the survey visit whether your specific property is a strong conversion or whether the numbers don't stack up yet.
Polton, tucked into the Esk valley between Lasswade and Loanhead, has a mix of older stone, post-war housing and newer infill. The valley setting means some plots are steeper and tighter than typical suburban sites, which can affect outdoor unit placement — it's rarely a dealbreaker but it's part of the design conversation. The larger properties on the valley tops and the modern builds around the edges are more straightforward.
This whole area is on mains gas, so the heat pump conversation is about long-term running costs and Home Energy Scotland funding rather than getting off an expensive oil or LPG supply. The numbers work best on the larger detached stock, but the grant and interest-free loan via the JME MCS route make it viable for a broader range of properties than most homeowners assume. SP Energy Networks is the DNO — we handle any SPEN notifications as part of the design.
MCS Partnership
Macara Heating is the engineer-led team on the ground. Our heat pump installations are delivered in partnership with JME Green Energy, who hold the MCS certification under which the work is registered. That's the route that unlocks Home Energy Scotland grant and interest-free loan funding for eligible properties. You get a local team you can actually speak to, with a proper MCS paperwork trail behind it.
Home Energy Scotland
Grant + interest-free loan for your air source heat pump
Eligible Lasswade properties can apply for a Home Energy Scotland grant (up to £7,500, or up to £9,000 with the rural/island uplift) and an interest-free loan of up to £7,500 on top. Exact amounts are confirmed at survey. We handle the paperwork alongside the design work. Note: the Boiler Upgrade Scheme (BUS) is England and Wales only — it does not apply in Scotland.
Service Scope
The 1970s to 1990s detached stock across Bonnyrigg and the modern detached around Lasswade and Polton's edges. Solid fabric, generous gardens, enough radiator output to support a lower flow temperature. These installs deliver reliable comfort and meaningful long-term running-cost savings, backed by Home Energy Scotland funding via the JME MCS route.
The three-bedroom semis across Bonnyrigg and Lasswade with reasonable garden space and upgraded fabric. Slightly smaller than the full detached, but with enough heating demand and outdoor space for a well-sized heat pump. We'll confirm the numbers on the survey visit before anyone talks price.
MCS installations are delivered in partnership with JME Green Energy, who hold the MCS certification under which the work is registered. You get Macara as the local engineer-led team on the ground and JME's MCS paperwork trail behind it — the route that unlocks Home Energy Scotland funding for eligible Lasswade-area properties.
How It Works
Step 1
We're based in Danderhall, about fifteen minutes from most of the Lasswade and Bonnyrigg area. We come out to your property, look at the fabric, the existing heating system, outdoor siting options and the realistic path forward. If a heat pump isn't right for your house, we'll tell you on the day.
Step 2
If the property looks suitable, we move to a full MCS heat loss survey and a properly sized system design. The MCS paperwork is handled in partnership with JME Green Energy so the install qualifies for Home Energy Scotland grant and interest-free loan funding where the property is eligible — exact amounts confirmed at survey.
Step 3
Written quote with a clear breakdown, Home Energy Scotland grant and interest-free loan paperwork handled alongside the design, and an agreed install date. No surprises mid-install.
Step 4
Install is typically 3–7 days depending on the property and whether radiators need changing. We commission the system to MCS and manufacturer standards, walk you through the controls and weather compensation settings, and leave you with clear written documentation. Then we're available for aftercare.
Coverage Detail
Older stone and Victorian properties in the village core along the North Esk, plus modern detached on the surrounding roads. The village-core properties carry some conservation sensitivity, so outdoor unit siting needs thought on the tighter plots. The modern stock around the edges is straightforward permitted development.
The 1970s to 1990s detached on Bonnyrigg's outer streets and the substantial newer estates on the eastern and southern edges. This is the strongest heat pump play in the area — big enough properties, proper gardens, solid fabric. The numbers work well with Home Energy Scotland grant and interest-free loan funding via the JME MCS route.
The inter-war and post-war terraces and semis in the older parts of Bonnyrigg. These are viable heat pump candidates in some cases, but honest — the smaller homes with tighter gardens and older fabric need a careful assessment. We'll tell you straight whether the conversion makes financial sense or whether fabric upgrades should come first.
Tucked into the Esk valley between Lasswade and Loanhead. A mix of older stone, post-war housing and newer infill. The valley setting means some plots are steeper than typical suburban sites, which affects outdoor unit placement. The larger properties on the valley tops and the modern builds are more straightforward.
FAQs
A typical whole-house air source heat pump install in the Lasswade and Bonnyrigg area sits in the £9,000–£16,000 range before Home Energy Scotland funding, depending on the property size, the state of the existing radiators, and whether any fabric upgrades are sensible at the same time. Eligible installs typically qualify for a Home Energy Scotland grant of up to £7,500 and an interest-free loan of up to £7,500 on top, applied for via the JME Green Energy MCS route. Exact amounts confirmed at survey.
On the larger detached stock, yes — the long-term running costs are typically lower, the system is more efficient, and Home Energy Scotland funding via the JME MCS route covers a substantial portion of the install cost. On the smaller terraces and semis it depends on the specific property. We'll tell you honestly on the survey visit whether the numbers justify a full conversion or whether a high-efficiency gas boiler is the better call for now.
No. Macara Heating is the local engineer-led install team on the ground.

In most cases, yes. The Boiler Upgrade Scheme (BUS) is England and Wales only and does not apply in Scotland. Lasswade and Bonnyrigg homeowners apply through Home Energy Scotland, which offers a grant of up to £7,500 for an air source heat pump and an interest-free loan of up to £7,500 on top. Eligibility usually requires owner-occupier status, a qualifying energy report, and installation by an MCS-certified installer. Our installs go through JME Green Energy's MCS certification, so eligible installs qualify.
It can, but it depends on the specific property. The inter-war and post-war semis in Bonnyrigg vary a lot — some have been insulated and upgraded over the years and convert well, others have fabric issues that should be addressed first. We'll do a proper heat loss survey and give you an honest view. If the numbers don't work yet, we'll tell you what would need to change before a heat pump makes financial sense.
