Air Source Heat Pump Installers in Gullane
Most Gullane homes heat with a mains-gas boiler, so the typical job here is a boiler-to-heat-pump conversion. Choosing the right installer is just as important as choosing the right unit: the Boiler Upgrade Scheme grant can only be claimed through an MCS-certified installer, the heat-loss survey they run determines the system design, and a Gas Safe registered engineer must handle the boiler removal.

What to Look for in an Air Source Heat Pump Installer
The Right Certifications for the Job
In the UK, the Boiler Upgrade Scheme grant requires an MCS-certified installer, who applies for the grant on your behalf and carries out a room-by-room heat-loss survey before installation. Any gas work, removing the old boiler and capping the supply, must be done by a Gas Safe registered engineer. Ask who is doing each part of the job and confirm they are appropriately certified for it.
Heat Pump Design Experience
A heat pump is a whole-home heating system, not a boiler swap-in. Look for installers who design systems weekly, take the heat-loss survey seriously, design for low flow temperatures (where the efficiency lives), and know which radiators genuinely need upsizing. Ask how many systems they have installed in the last 12 months.
A Complete Written Quote
A complete quote shows the price before the grant, the grant deduction, and your out-of-pocket figure, and covers the unit, hot water cylinder (a real line item if you have a combi boiler), any radiator upgrades, all plumbing and electrical work, removal and disposal of the old boiler, and commissioning, with 0% VAT already reflected.
Correct Sizing from the Heat-Loss Survey
Undersizing leaves rooms cold; oversizing wastes money and cycles the unit. UK sizing is driven by your home's heat loss, calculated room by room in the survey, not by bedroom count. As a rough guide from the current model ranges, well-insulated smaller homes suit 5-8kW of heat output, typical 3-4 bed homes 8-12kW, and large or older properties more. In your cooler climate zone, low-temperature output and radiator sizing matter even more, so expect the survey to drive the recommendation.
Workmanship Warranty
Your heat pump comes with a manufacturer product warranty (typically 5 to 7 years for UK models, often extendable through accredited-installer schemes). You also want a separate workmanship warranty from the installer covering the installation itself: pipework, mounting, drainage, and electrical work. Look for at least 12 months, in writing.
What to Expect During Installation
A typical air source heat pump installation in Gullane follows these steps. Most jobs take 2 to 5 days once the survey is done; your installer will confirm after the survey.
Heat-Loss Survey
Your installer visits your Gullane property and calculates heat loss room by room (an MCS requirement for grant-backed installs). This sets the heat pump output, the radiator sizing, the cylinder size, and where the outdoor unit can sit for noise and airflow.
System Design and Quote
You get a written quote covering the unit, cylinder, any radiator changes, and all work. Apply to Home Energy Scotland for the grant (and optional loan) before installation; the installer can help with the technical details.
Old System Removal
The existing boiler or heaters are disconnected and removed. If a gas boiler is coming out, a Gas Safe registered engineer disconnects and caps the gas supply (a legal requirement). Oil and LPG systems are decommissioned and the tank dealt with as agreed in the quote.
Heat Pump, Cylinder and Radiators
The outdoor unit is mounted and connected, the hot water cylinder fitted (or added, if you had a combi boiler), any radiators upsized, and the controls wired in. Pipework and electrics are completed by appropriately qualified trades.
Commissioning and Testing
The system is filled, balanced, and commissioned: flow temperatures set, controls configured, hot water tested. Good commissioning is where the design SCOP becomes a real-world running cost, so ask for the commissioning record.
Paperwork and Handover
Your installer provides the invoice, the MCS certificate, commissioning documentation and warranty registrations. Keep everything: manufacturer warranties generally require professional installation, and the paperwork is your proof.
What Affects Installation Cost in Gullane
Out-of-pocket costs in Gullane typically range £750 - £7,650 (indicative, June 2026). Here is what pushes the price up or down.
Urban Pricing
As an urban area, Gullane has good installer competition which helps keep prices in check. Travel costs are minimal and most installers know the local housing stock well.
Combi Boiler? Add a Cylinder
A heat pump heats water into a hot water cylinder. If you currently have a combi boiler there is no cylinder, so the conversion adds one, plus the space for it (an airing cupboard or similar). This is a real cost line that pushes quotes toward the top of the range; make sure it is itemised.
Radiator Upgrades
Heat pumps run most efficiently at lower flow temperatures, so the heat-loss survey may recommend upsizing a few radiators. High-flow-temperature R290 models can avoid a re-pipe in many retrofits. Each swapped radiator adds labour and materials, so check how many the quote includes.
Electrical Work
Older Gullane homes may need consumer unit work or a dedicated circuit for the heat pump. Ask the installer to check this during the survey so it is priced into the quote rather than appearing as a surprise.
Old System Removal
Most installers include removal and disposal of the old boiler in the quoted price, but confirm it. Gas boiler removals involve Gas Safe work to cap the supply, which should be itemised.
Access and Siting
The outdoor unit needs airflow around it and sensible placement for noise, away from bedroom windows and close boundary walls. Tight terraces and difficult access add time and cost. Discuss placement options during the survey.

How much does an air source heat pump installation cost in Gullane?
In Gullane, Scotland, most households pay £750 - £7,650 out of pocket (indicative, June 2026) after the Home Energy Scotland grant of up to £7,500 comes off a typical pre-grant installed price of £8,250 - £15,150. Combi-to-cylinder conversions and radiator upgrades push toward the top of the range. As an urban area, Gullane has competitive installer pricing thanks to multiple companies servicing it.
How do I claim the heat pump grant in Gullane?
Scotland uses the Home Energy Scotland grant (up to £7,500, or £9,000 with the rural and island uplift) plus an optional £7,500 interest-free loan, instead of the Boiler Upgrade Scheme. You apply through Home Energy Scotland yourself, and it must be approved before installation, so start the application before booking the install. Accurate as at June 2026.
How long does an installation take in Gullane?
It starts with a heat-loss survey visit (an MCS requirement), then the installation itself usually takes 2 to 5 days depending on whether a hot water cylinder needs adding (combi conversions) and how many radiators are being upsized. A straightforward boiler swap with the cylinder in place sits at the short end. Your installer will confirm the schedule after the survey.
Who should do the installation in Gullane?
In the UK, the Boiler Upgrade Scheme grant requires an MCS-certified installer, who applies for the grant on your behalf and carries out a room-by-room heat-loss survey before installation. Any gas work, removing the old boiler and capping the supply, must be done by a Gas Safe registered engineer. Ask who is doing each part of the job and confirm they are appropriately certified for it.
Which air source heat pump brands do Gullane installers fit?
Most Gullane installers can fit any of the eight brands with a verified UK presence: Mitsubishi Electric Ecodan (assembled in Livingston, Scotland) has the widest installer familiarity, Daikin Altherma and Samsung EHS are widely stocked, Vaillant aroTHERM Plus and Viessmann Vitocal are the premium German options, Grant Aerona3 is the rural and oil-belt favourite, Worcester Bosch brings the boiler-era badge, and Octopus Cosy is installed by Octopus's own teams. Get quotes for 2-3 brands to compare price and warranty side by side.
Is there a workmanship warranty?
A reputable Gullane installer should provide a workmanship warranty of at least 12 months on the installation itself, in addition to the manufacturer's product warranty (typically 5 to 7 years on the unit for UK models, often extendable through accredited-installer schemes). Ask for the workmanship cover in writing before accepting a quote. The Consumer Rights Act 2015 also requires installation work to be done with reasonable care and skill, and MCS installations carry prescribed consumer protection arrangements.
Do Gullane installers handle gas boiler removals?
Yes. With most Gullane homes on a mains-gas boiler, boiler-to-heat-pump conversions are the routine job for local installers. A Gas Safe registered engineer disconnects and caps the gas supply (a legal requirement), and the old boiler is removed. If you have a combi boiler, the conversion adds a hot water cylinder, which the quote should itemise. With the Ofgem cap gas rate rising 27% on 1 July 2026, end-of-life conversion instead of fitting another boiler is an increasingly common request.
