Most recent win: Scotland Heating Installer of the Year 2026 at the Heating Installer Awards, going through to the UK national final at InstallerSHOW on 24 June 2026. That same Bathgate installation, an air source heat pump and underfloor heating system designed for around 450% efficiency at a 35°C flow temperature, picked up a Highly Commended at the Scottish Energy Efficiency Awards 2025. The same heat loss survey and design standard applies to every heat pump we install, Georgian townhouses included.
“Sean was hands-on throughout the entire process. He explained how simple DIY improvements would lower the heat loss in our home, giving us practical, cost-conscious tips to bring our energy bills down.”

Haddington's Stone-Built Core and Why Air Source Heat Pump Installation Works Here
A Haddington heat pump installation starts from a straightforward number: £7,500 off the cost, available to every eligible owner-occupier in the town, no means test attached. Getting there properly, though, means understanding what you’re heating first.
Much of the town centre carries conservation area status dating back to the late 1960s, extended roughly a decade later, taking in the Georgian streetscape around Court Street, where terraced houses on the south side still echo the proportions William Adam gave Haddington Town House in 1748. Stone-built properties are the norm here, many with the high stone garden walls East Lothian Council’s own heritage documentation flags as worth protecting. St Mary’s Collegiate Church, the longest parish church in Scotland at over 200 feet, sits on the River Tyne beside the twelfth-century Nungate Bridge, built from red sandstone quarried at nearby Garvald, the most visible use of that stone in town.
Solid stone like that holds heat differently to a modern cavity wall, and a heat pump sized off a square-footage guess, not a proper room-by-room survey, will leave a Court Street townhouse running cold on the coldest nights.
Here’s the grant picture in plain terms. Home Energy Scotland’s standard £7,500 applies across Haddington, town centre included, and isn’t tied to income or means-tested in any way. Survey to grant paperwork usually moves fast: your engineer confirms eligibility at the same visit that measures heat loss, and we submit on your behalf once the system is designed.
There’s also an upside worth checking, not dismissing: the £9,000 rural uplift exists for postcodes classed as remote rural, island, or off-gas accessible rural, and while a property inside Haddington itself sits above the population threshold that definition uses, working farms and smaller hamlets out in the wider parish, particularly ones without a mains gas connection, can genuinely fall into that higher band. We check every postcode against Home Energy Scotland’s own classification before quoting, so nobody pays for a grant figure that doesn’t apply, and nobody misses one that does.
Running costs matter just as much as the grant. An oil boiler nearing the end of its life on a rural East Lothian property is usually the trigger that brings a homeowner to us, and a correctly sized heat pump on a low flow temperature typically undercuts oil on a like-for-like comparison, sometimes by a wide margin given how volatile oil pricing has been. A well-maintained heat pump also runs for 15 to 20 years or more with annual servicing, well past the point most gas or oil boilers are due for replacement. Solid stone terraces and villas like Haddington’s are exactly the property type covered in our guide to heat pumps for old and existing Scottish homes, where flow temperature and radiator sizing decide whether the system actually keeps a period property warm.
Haddington sits roughly 30 minutes from Edinburgh, and the survey and design standard we bring here is the one behind installing a heat pump in Edinburgh, extended along the coast to North Berwick and the rest of East Lothian.

Why Haddington Homeowners Choose Aventus Eco for Air Source Heat Pump Installation
Installers covering Haddington range from national franchises reading off a script to single-engineer outfits with no real design process. Six things set Aventus Eco apart:
- You deal with the engineer, not a switchboard. Sean surveys, designs and installs your system personally, and stays reachable on WhatsApp long after the van’s gone. We cover the whole of Scotland, East Lothian’s market towns and farms included.
- Grant eligibility confirmed at the survey, not guessed at. Every Haddington homeowner gets the standard £7,500 as a baseline, and we check your specific postcode for the rural uplift rather than either overpromising it or leaving it on the table unchecked.
- Heat loss surveys built for solid stone. An air heat pump in Haddington sized off a modern new-build calculation will leave a Georgian townhouse cold. We measure room by room, accounting for solid stone construction, before specifying anything.
- Heat Geek accredited. Sean holds Heat Geek certification, a standard only a small number of Scottish installers reach. What that means in practice is explained on our Heat Geek installation process page.
- Conservation area placement handled before you commit. Haddington’s Georgian core sits inside a designated conservation area, and outdoor unit siting needs to respect permitted development rules, with listed buildings needing consent regardless of position. We clear this with East Lothian Council at survey stage and settle any heat pump planning permission requirement before you order.
- Full MCS certification. Home Energy Scotland grants require it, and we handle the entire paperwork trail so the £7,500 lands without you chasing forms.

Our Simple 3-Step Process
Free Engineer-Led Survey & Quote
Your engineer measures heat loss room by room across your Haddington property, confirms your postcode's grant classification on the spot, and prices the system against a genuine like-for-like running-cost comparison, whatever fuel you're on now. Expect the full quote within a week, sooner if your boiler's already failed.
Fast & Expert Installation
Most Haddington installs run 5 working days, Monday to Friday. Stone townhouses needing radiator upgrades, or larger rural properties with more pipework, can take longer, and we flag that at survey stage rather than on the day. Garden walls and stonework get protected throughout.
Enjoy Lower Bills & Comfort
We tune the weather compensation curve properly rather than leaving factory settings in place, which is where most of the real-world saving actually comes from. For rural properties coming off oil, we check back after the first winter to confirm the running-cost figures matched what we quoted. Serviced annually, the system should keep performing for 15 to 20 years or more.
We install trusted brands like Vaillant and Panasonic, always chosen to match your home.
Heat Pump Grants Available to Haddington Homeowners
Every eligible Haddington owner-occupier starts from the same figure: a £7,500 Home Energy Scotland grant, not means-tested, applied to a Georgian townhouse in the centre or a farmhouse on the parish edge alike. On top of that sits an optional interest-free Home Energy Scotland loan of up to £7,500, which spreads whatever the grant doesn’t cover without adding interest. The heat pump grants in Scotland 2026 guide covers exactly how the grant and loan work together.
Then there’s the upside worth checking: the £9,000 rural uplift, an extra £1,500 on top of the standard grant, reserved for postcodes the Scottish Government classes as remote rural, island, or off-gas accessible rural. A property inside Haddington town itself sits above the population threshold that classification uses, but working farms and smaller settlements out in the wider parish, especially ones with no mains gas connection, are genuinely worth checking rather than writing off. We confirm your exact postcode against Home Energy Scotland’s own system before any number goes in a quote.
For a typical Haddington heat pump system costing £15,000 to £20,000 fully fitted, larger stone-built villas sitting higher, the standard grant brings out-of-pocket cost to between £7,500 and £12,500, less again if the rural uplift applies to your postcode. Set against an ageing oil boiler’s running costs, common on Haddington’s rural fringe, the numbers tend to work in the heat pump’s favour. See our air source heat pump cost in Scotland 2026 guide for a size-by-size breakdown.
Home Energy Scotland will want a recent EPC before releasing funds, and only a system covering 100% of heating and hot water qualifies, so hybrid setups sit outside grant funding. We handle the HES paperwork on every job.

Penny and Monique’s 1920s Sandstone Home in Mount Florida
Penny and Monique’s 1920s sandstone end-terrace in Mount Florida, a short walk from Hampden Stadium, was exactly the kind of property people are told can’t run on a heat pump: older, draughty, lightly insulated. They found Aventus Eco through Loco Home Retrofit, a Glasgow co-op connecting homeowners with vetted installers. After a full heat loss survey, we designed a 7kW Vaillant aroTHERM plus system at a 45°C flow temperature, replaced four ageing radiators with high-output units, added one upstairs and two more in the new rear extension, and corrected substandard plumbing left by a previous installer.
The 250L Vaillant cylinder and system components were fitted into a tight 1.2m-high basement to save upstairs living space. The result: a constant 21°C throughout the house in every season, regardless of the property’s age or insulation level. A home written off by others became one of our best examples of what a properly designed system can do.
“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. Special thanks to Loco Home Retrofit for pointing us in the right direction.”

Frequently Asked Questions
How much does an air source heat pump cost in Haddington?
Fully installed pricing for a typical Haddington property runs £15,000 to £20,000 before the Home Energy Scotland grant, with larger stone-built villas sitting higher. After the standard £7,500 grant, most homeowners land between £7,500 and £12,500 out of pocket. Your engineer gives a fully itemised quote at survey stage, no obligation attached.
How much heat pump grant can I get in Haddington?
£7,500 for any eligible owner-occupier in Haddington, town centre or parish. It isn’t means-tested. On top of that, an optional interest-free Home Energy Scotland loan of up to £7,500 is available to cover whatever the grant doesn’t. If your property sits out in the wider parish, particularly a farm or hamlet off the mains gas grid, it’s worth asking whether the £9,000 rural uplift applies too. We check your exact postcode against Home Energy Scotland’s classification before you commit to anything.
Can an air source heat pump replace my boiler in Haddington?
Yes, and boiler replacement in Haddington is the most common call we get. Town-centre properties are usually on mains gas, parish properties often on oil, and either way the old fuel supply or tank is capped and removed, the hot water cylinder swaps for a heat pump-compatible unit, and the existing radiators are kept wherever the survey shows they can still do the job.
Are hybrid heat pumps available in Haddington?
Yes, though they sit outside Home Energy Scotland grant funding. Where a full retrofit isn’t the right first move for a Haddington property, Aventus Eco fits a hybrid system pairing a smaller heat pump with the existing boiler, so the heat pump covers most annual heating demand and the boiler only kicks in on the coldest days. Only a system covering 100% of heating and hot water qualifies for the grant.
Why does a Georgian stone townhouse in Haddington need different sizing to a new build?
Solid stone construction, the norm across Haddington’s conservation area, loses heat on a different curve to a modern cavity wall, and usually needs a lower flow temperature paired with larger radiators to run efficiently. A generic square-footage estimate undersizes the system almost every time. We calculate heat loss room by room before specifying an air heat pump in Haddington, which is what a period property genuinely needs.
How do you handle heat pump quotes in Haddington for rural, off-gas properties?
The same way as a town-centre job, just with a different starting point. We check whether the property qualifies as off-gas accessible rural, which affects both the grant band and the running-cost comparison against oil. Heat pump quotes in Haddington always include both the standard and, where it genuinely applies, the uplifted grant figure, so you’re comparing real numbers rather than a guess.
How long does heat pump system installation take in Haddington?
Most jobs, including in Haddington, run 5 working days, Monday to Friday: old boiler or oil tank out, outdoor unit sited and weatherproofed, pipework and cylinder work, radiator upgrades where needed, full commissioning. A stone townhouse needing more extensive radiator work can add a few days.
