Boiler Installation in Midlothian
Gas Safe registered boiler installers based in Danderhall — Midlothian is our local patch. Proper sizing, clean installs, and an honest conversation about gas, LPG or a heat pump conversion where it makes sense.
Macara Heating is based in Danderhall, right on the Midlothian boundary, which makes this county the most local boiler work we do. We install and replace gas and LPG boilers across the whole of Midlothian — Dalkeith, Eskbank, Bonnyrigg, Lasswade, Loanhead, Penicuik, Newtongrange, Mayfield, Gorebridge, Roslin and the rural villages stretching south toward the Borders. Every install is handled by Gas Safe registered engineers with more than twelve years of heating experience across the Lothians. We're LPG certified too, which matters across rural south Midlothian where mains gas runs out. Proper sizing, clean installs, manufacturer warranties honoured — and where another fossil-fuel swap isn't the right long-term call, we'll be straight with you about a heat pump conversion on the JME MCS route instead.
Local Context
Midlothian's housing stock splits the boiler conversation into three distinct patches. Dalkeith, Eskbank, Bonnyrigg and Lasswade carry a strong mix of inter-war and post-war semis, 1960s–1990s detached and modern estates, almost all on mains gas, where a clean combi or system boiler swap is the standard job. Eskbank in particular has the kind of larger detached housing where a system boiler with a properly sized unvented cylinder usually beats a combi pushed beyond its comfortable flow rate.
The ex-mining village belt — Newtongrange, Mayfield, Gorebridge, Rosewell and parts of Loanhead — is mostly modest inter-war and post-war terraces and semis on mains gas, with newer detached on the village edges. These are mostly straightforward combi swaps, often with a power flush on older systems to protect the new heat exchanger. We'll be honest about whether the existing pipework and radiators are worth keeping or whether a partial overhaul makes more sense alongside the boiler.
Penicuik is a mix of town-centre stone, post-war estates and larger detached on the valley edges. The town is almost entirely on mains gas and the work is standard Gas Safe territory, but pockets around the outskirts and the villages running south toward the Moorfoot edges drop off the mains gas grid. Dalkeith historic centre, Newbattle and Roslin village sit inside Midlothian Council conservation areas, so flue siting and building warrant sign-off on listed and older stone properties is part of the install rather than an afterthought.
The rural south of the county — Temple, Carrington, Howgate, Nine Mile Burn and the farmland out toward West Linton — is genuinely off-gas. Oil, LPG and older electric storage heating in farmhouses, converted steadings and rural cottages. Macara Heating is LPG certified to handle LPG boiler installs, servicing and repairs out here. For oil properties we'll give you a straight view on whether another oil swap is the right long-term call or whether the case for a heat pump on the JME MCS route — with Home Energy Scotland grant and interest-free loan funding on top — makes more sense for your household. Either answer is fine; we just don't push people into decisions that won't serve them.
Service Scope
The standard Midlothian upgrade across Dalkeith, Bonnyrigg, Loanhead, Penicuik and the ex-mining village belt — old system or regular boiler out, modern combi in, cylinder removed where it makes sense. Proper sizing against your actual hot water demand, Gas Safe paperwork handled, old kit removed cleanly, and the warranty registered on your behalf.
For the larger detached housing through Eskbank, Lasswade, Bonnyrigg outskirts and Penicuik valley edges, a system boiler with a well-sized unvented cylinder is often the right call over a combi. We design the cylinder capacity to your actual usage and commission the G3 unvented setup properly.
Macara Heating is LPG certified — useful across rural south Midlothian, from Temple and Carrington through Howgate and Nine Mile Burn out toward West Linton and the Moorfoot edges. We install, service and repair LPG boilers, handle flue gas analysis, and give you an honest view on whether LPG is the right long-term call versus a heat pump swap.
How It Works
Step 1
We're based in Danderhall, so most of Midlothian is a fifteen-minute drive. We come to your property, look at the existing system, the pipework, the gas or LPG supply, the flue route and your actual hot water demand. You get a straight recommendation — combi, system, LPG, or a conversation about a heat pump if that looks like the better long-term call.
Step 2
A clear written quote with the boiler model, warranty length, any filters or accessories, power flush if needed, building warrant fees where relevant, and the install timeline. No hidden extras added once we're on site.
Step 3
Most Midlothian boiler swaps are a one- to two-day install. We protect the property properly, fit the new unit to manufacturer specification, flush the system where needed, commission it against the benchmark commissioning sheet, and register the warranty on your behalf. Gas Safe notification handled, building warrant sign-off where applicable.
Step 4
Walk-through of the new controls, thermostat setup, written commissioning paperwork for your records, and a clear route back to us for the annual service and any warranty claims. We're a local team based ten minutes down the road — you're not phoning a call centre a hundred miles away.
Coverage Detail
Dalkeith, Eskbank and Newbattle are the closest part of Midlothian to us — high-volume gas boiler territory across post-war semis, modern estates and the larger detached housing of Eskbank where system boilers with unvented cylinders often beat combis on hot-water demand. Dalkeith historic centre and parts of Newbattle sit in conservation areas, so flue routing on the older stone needs careful thought and we handle the building warrant side as part of the install.
Bonnyrigg, Lasswade and Polton cover a big spread of mid-twentieth-century and modern detached and semi-detached housing on mains gas. Most jobs are straightforward combi swaps or combi-from-system conversions where the cylinder comes out and the airing cupboard comes back to the homeowner. Larger Lasswade detached often justifies a system boiler instead. Lasswade village has historic stone that needs a touch of conservation consideration on flue siting.
Loanhead, Bilston and Roslin are a mix of ex-mining terraces, 1960s–1980s estates and newer detached on village edges, all on mains gas. Standard combi territory across most of the stock, with the larger newer detached around Straiton justifying system boilers. Roslin village conservation area brings flue and building warrant considerations on the older stone, but the wider village is normal Gas Safe work.
The ex-mining village belt is mostly modest inter-war and post-war terraces and semis on mains gas. Standard combi swap territory, often with a power flush to protect the new heat exchanger from old radiator sludge. We'll be honest about whether the existing pipework and radiators are worth keeping or whether a partial overhaul makes more sense alongside the boiler. Newer detached on the village edges is straightforward.
Penicuik is town-centre stone, post-war estates and larger detached on the valley edges, almost all on mains gas. Standard combi and system boiler installs across the town, with a careful eye on flue siting on the older stone in the historic centre. Pockets on the outskirts and the villages south toward the Moorfoot edges drop off the mains gas grid — that's LPG and heat-pump conversation territory.
The rural south of the county — Temple, Carrington, Howgate, Nine Mile Burn and the farmland out toward West Linton — is genuinely off-gas. Oil, LPG and older electric storage heating in farmhouses, steadings and rural cottages. Macara Heating is LPG certified for the off-gas properties, and we'll be honest with oil homeowners about whether another fossil-fuel swap or a heat pump conversion on the JME MCS route is the right long-term call.
FAQs
Yes — and Midlothian is the most local work we do. Macara Heating is based in Danderhall, right on the Midlothian boundary, which puts us within fifteen minutes of most of the county. We cover Dalkeith, Eskbank, Bonnyrigg, Lasswade, Loanhead, Penicuik, Newtongrange, Mayfield, Gorebridge, Roslin and the rural villages south toward the Borders. Combi, system and LPG installs all handled by the same local team.
A like-for-like gas combi replacement in a Bonnyrigg or Newtongrange semi typically lands in the £2,200–£3,500 range fitted. A larger system boiler with an unvented cylinder in an Eskbank or Lasswade detached usually sits in the £3,500–£5,500 range. LPG installs in the rural south vary with tank and supply arrangements — we quote those specifically on the survey visit. Every quote goes in writing with a full breakdown.
Yes. Macara Heating is LPG certified and we install, service and repair LPG boilers — useful across Temple, Carrington, Howgate, Nine Mile Burn and the farmland out toward West Linton and the Moorfoot edges. We'll also give you an honest view on whether LPG is the right long-term call for your property or whether a heat pump conversion on the JME MCS route would serve you better on running costs.
For most modest inter-war and post-war terraces in the ex-mining belt, a high-efficiency gas combi is still the right call today. The fabric usually isn't ready for a heat pump without insulation work first, the housing is on mains gas, and a clean combi swap with a power flush typically gives the best balance of comfort, running cost and capital outlay. We'll tell you straight on the survey visit if your specific property is the exception.
It depends on your property and how long you plan to stay. For many rural south Midlothian oil properties the honest answer today is that an air source heat pump on the JME MCS route — which unlocks Home Energy Scotland grant and interest-free loan funding — is the better long-term call than another oil swap. That isn't always the right answer though, and we'll look at your specific house on the survey visit and give you a straight recommendation. We'd rather you made the right call than just sold you another oil boiler.
Yes. Dalkeith historic centre, Newbattle and Roslin village sit inside Midlothian Council conservation areas where flue terminal siting on listed and older stone properties needs careful thought, and building warrant sign-off is part of the install. We handle that side of the job rather than leaving it with the homeowner.
