Heat Pump Installation in Kilmacolm: Ditch the Oil Tank, Not the Comfort
Heat Geek and MCS-certified heat pump installation in Kilmacolm, built around the large detached villas and Arts and Crafts houses that still run on oil. A proper heat loss survey, a system sized for a big house, and the oil tank gone for good.
Most recent win:
Most recent win: Scotland Heating Installer of the Year, Heating Installer Awards 2026. We went on to the UK national final at InstallerSHOW on 24 June 2026. Our Bathgate air source heat pump and underfloor heating install was also recognised at the Scottish Energy Efficiency Awards 2025, with a monitored efficiency of 440% for November at outdoor temperatures of 0°C to -5°C. The same heat loss survey and design standard goes into every install, including the oil-to-heat-pump conversions we carry out across the Gryffe Valley.
“Aventus took the time to get the design right for our home, including properly working out our heat loss before sizing anything. Originally I wanted to keep the oil boiler ‘just in case’. I’m glad I took the leap to ditch it and trust the Aventus design. The house is comfortable and warm throughout, and they made the grant process easy.”

Heat Pump Grants Extended for 2026

Kilmacolm's Big Villas, and Why the Oil Tank Doesn't Have to Stay
Kilmacolm’s big villas date from the 1870s to the 1930s, once the railway reached in 1869. It’s the housing stock in our guide to heat pumps for old and existing Scottish homes: thick stone or roughcast walls, high ceilings, heating bolted together over time.
- James Salmon, William Leiper, and the firm of Sir John James Burnet all left work in Kilmacolm.
- Windyhill (Mackintosh, 1900-02) and Rowantreehill (Salmon, 1898) stand together on Rowantreehill Road, both listed.
- Two conservation areas: Kilmacolm (South West), designated 1972, and Kilmacolm, The Cross, 2015.
- Northern slope of the Gryffe Valley: exposed villas take the weather coming up it.
- Larger villas set back from the centre often still run on oil: a tank in the garden, deliveries booked every few months.
- Grant handling and parts logistics run through heat pump installation in Glasgow; the job here is more often an oil conversion than a terrace swap.

Our Simple 3-Step Process for Heat Pump Installation in Kilmacolm
Step 1: Free Engineer-Led Survey & Quote
Your engineer visits your Kilmacolm property, carries out a full room-by-room heat loss calculation, takes thermal images of problem areas, and checks the existing oil supply and tank if you have one. You get a clear breakdown of system size, cost and running costs, with the quote back within a week.
Step 2: Fast & Expert Installation
Most Kilmacolm installations run to a 5 working day schedule, Monday to Friday: removing and decommissioning the old oil tank and boiler, fitting the outdoor unit somewhere the neighbours (and any planning officer) won't object to, upgrading radiators where needed, and commissioning to MCS standards. A particularly large or complex property can run longer.
Step 3: Enjoy Lower Bills & Comfort
We set your weather compensation curve, help you pick the right tariff (Octopus Cosy works well for most heat pump homes), and check in after the first winter to confirm the system is performing as quoted. No oil deliveries to book, and no oil price to watch before the cold months.
We install trusted brands like Vaillant and Panasonic, always chosen to match your home.
Heat Pump Grants Available to Kilmacolm Homeowners
Home Energy Scotland offers a grant for air source heat pump installation, non-repayable, plus an optional interest-free loan for the balance. We check your postcode against current HES criteria at survey stage. Full detail is in our heat pump grants in Scotland 2026 guide.
- £7,500 HES grant, rising to £9,000 where the rural uplift applies.
- Interest-free HES loan of up to £7,500 to cover the balance.
- Fully fitted pricing: £17,000 to £25,000, depending on floor area, radiator work, and oil tank removal.
- Out-of-pocket cost after the £7,500 grant: typically £9,500 to £17,500.
- Grant paperwork handled by us as part of every install, no separate forms beyond the standard HES ones.
Kilmacolm’s larger villas need a bigger system than a typical semi, so most homeowners find the numbers stack up within a handful of years against the oil saving. See the size-by-size breakdown in our air source heat pump cost in Scotland 2026 guide.

Penny and Monique’s 1920s Sandstone Home in Mount Florida
Penny and Monique’s 1920s sandstone end-terrace in Mount Florida was exactly the kind of property people are told cannot run on a heat pump: older, draughty, and lightly insulated. They came to Aventus Eco through Loco Home Retrofit, a Glasgow co-op that connects homeowners with vetted installers. After a full heat loss survey we designed a 7kW Vaillant aroTHERM plus system running at a 45°C flow temperature, replaced four ageing radiators with high-output units, and corrected substandard plumbing left by a previous installer.
The Vaillant 250L hot water cylinder and system components were fitted into a tight 1.2m-high basement to save living space upstairs. The result is a constant 21°C throughout the house in every season, at over 450% efficiency despite the age and insulation level of the property.
“We were told a property like ours couldn’t run on a heat pump. Aventus Eco proved everyone wrong. The house is warm all the time, the new radiators look great, and we love that the whole system is neatly hidden away in the basement.”

Frequently Asked Questions
Do air source heat pumps work in Kilmacolm's older villas?
Yes. The large stone and roughcast villas around Kilmacolm, including the substantial homes on and around Rowantreehill Road, suit air source heat pump installation well once the system is sized correctly. A proper room-by-room heat loss survey, sized radiators, and the right flow temperature are what make it work in a big, older Kilmacolm property, not a smaller version of what suits a modern flat.
How much does an air source heat pump cost in Kilmacolm?
For a typical larger Kilmacolm property, fully installed pricing usually runs from £17,000 to £25,000 before the £7,500 Home Energy Scotland grant. An air heat pump in Kilmacolm is usually sized for a bigger floor area than a city terrace, so it costs more upfront, but the running-cost saving against oil is bigger too. Your engineer gives a full itemised quote at survey stage with no obligation.
What heat pump grants are available in Kilmacolm?
Home Energy Scotland offers a £7,500 grant for air source heat pump installation in Kilmacolm, available to owner-occupiers meeting basic property and income criteria. An interest-free HES loan covers the balance up to a further £7,500 if needed. The Boiler Upgrade Scheme does not apply in Scotland; HES is the relevant route, and we handle all the paperwork.
Can a heat pump replace an oil boiler in Kilmacolm?
Yes. Boiler replacement in Kilmacolm more often means taking out an oil boiler than a gas one: the old boiler and tank come out, the fuel line is capped off, and the existing radiator system is retained with targeted upgrades where the heat loss survey calls for it. The hot water cylinder is swapped for a heat pump-compatible unit as part of the same visit.
How do I get heat pump quotes in Kilmacolm?
Book a free engineer-led survey and one of our heat pump installers visits your property directly, no call centre or salesperson involved. You get a full heat loss calculation, an honest recommendation on system size, and an itemised quote for your specific Kilmacolm property within a week.
Are hybrid heat pumps available in Kilmacolm?
Yes. Where a full switch isn’t practical straight away, Aventus Eco offers hybrid heat pump installation in Kilmacolm, pairing a smaller heat pump with the existing boiler so the heat pump covers the bulk of annual heating demand. Note that hybrid systems are not eligible for HES grant funding, which only applies to a full heat pump system installation.
How long does a heat pump system installation take in Kilmacolm?
Most Kilmacolm installations run to a 5 working day schedule, Monday to Friday, the same as our typical heat pump install regardless of property size. This covers the outdoor unit, pipework, new cylinder, radiator upgrades where needed, full commissioning, and removing an oil tank and supply line where one exists. A particularly large or complex Kilmacolm property can take longer.
Do you provide heat pump servicing and maintenance in Kilmacolm?
Yes. We offer annual servicing for every heat pump we install in Kilmacolm, plus ongoing aftercare for the lifetime of the system. Your installer stays reachable directly by WhatsApp, and annual servicing keeps a big system running at the efficiency it was designed for.
The full renewables package prices the pump, panels and battery as one project.
