A typical hybrid heating installation in Scotland ranges from around £6,000 to £12,000, subject to survey. The price depends on property size, heat pump capacity, radiator changes, and whether a new cylinder is needed. The only accurate price comes from a survey that measures your home and produces an itemised written proposal.
The cost of a hybrid heating system depends on the size of your property, the heat pump capacity needed, whether your existing boiler can be retained, and the extent of any radiator or pipework changes. Because every property is different, the only accurate way to price a hybrid installation is through a survey that measures your home heat loss and assesses your existing system. What follows are typical ranges to give you a sense of scale, but they are not quotes — the final cost is confirmed in the written proposal after the survey.

What is the typical installation cost of a hybrid system?
A typical hybrid heating installation in Scotland ranges from around 6,000 to 12,000 pounds, subject to survey. The range reflects property size, heat pump capacity, radiator changes, and whether a new cylinder is needed.
This figure is typical, subject to survey, and covers the heat pump unit, the indoor hydraulic module, the intelligent controller, installation labour, and commissioning. It assumes your existing boiler can be retained and is in serviceable condition. Properties with larger heat loads need a higher-capacity heat pump, which costs more. If radiators need upgrading to work efficiently at lower flow temperatures, that adds to the total. A new hot water cylinder, if required, is also a factor. The survey produces a written, itemised proposal so you can see exactly what each component costs before deciding whether to proceed. No installation is booked until you have reviewed and approved the proposal.
What affects the final price?
The main cost variables are property size and heat loss, heat pump capacity, the number of radiator upgrades, whether a new cylinder is needed, and the complexity of the outdoor unit installation.
A larger property with more rooms and higher heat loss requires a bigger heat pump, which costs more. Homes with solid walls or limited insulation may need more radiator upgrades to work at lower flow temperatures. If your current cylinder is too small for the heat pump or is nearing end of life, a replacement adds cost. The outdoor unit installation varies — a straightforward wall mount on a gable end is simpler than a ground-mounted pad requiring a concrete base and trenching. Electrical work may be needed if your consumer unit or supply requires upgrading. Each of these factors is assessed during the survey and itemised in the proposal.
How do running costs compare to a boiler alone?
Running costs depend on the ratio of electricity to gas or oil prices. For most of the heating season the heat pump runs alone, so costs shift towards electricity. The boiler only fires on the coldest days.
A heat pump typically delivers three to four units of heat for every unit of electricity it consumes. This means that during the milder months — which is most of the heating season in Scotland — your running costs are driven by electricity rather than gas or oil. When the boiler takes over on the coldest days, fuel consumption shifts back to that fuel. The exact saving depends on your electricity tariff, the efficiency of your existing boiler, and how well your home retains heat. The survey provides an estimate of annual running costs based on your property measured heat loss, your current fuel type, and your typical usage pattern. We do not guarantee savings — the balance between electricity and fuel prices changes over time.
Is finance available?
Interest-free credit up to £30,000, subject to status. We can discuss options after the survey if you decide to proceed.
If you would like to spread the cost, interest-free credit of up to £30,000 is available, subject to status and affordability. Terms and conditions apply. We provide details after the survey so you can decide with the full picture of costs in front of you. We install through MCS-certified partners.
How do I get an accurate price for my home?
The only way to get an accurate price is through a survey. It measures heat loss for every room, assesses your existing system, and produces an itemised written proposal. The survey takes two to three hours and is no-obligation.
An online calculator or phone estimate can give a rough range, but it cannot account for the specifics of your property — your radiator sizes, your insulation levels, your electrical supply, or the best location for the outdoor unit. The survey does all of this. It takes two to three hours, covers every room, the loft, the hot water system, and the outdoor location. You receive a written report with a heat loss calculation, a proposed system design, a list of any radiator changes, and an itemised cost. You are under no obligation to proceed. We install through MCS-certified partners.
Frequently asked questions
Is the survey no-obligation?
Yes, the survey is no-obligation and takes two to three hours. You receive a written report and are under no obligation to proceed.
Will I need to replace my boiler as part of the installation?
Not usually. If your boiler is still serviceable it can be retained. If it needs replacing, the survey flags it and the cost is itemised separately.
Does the price include VAT?
The written proposal after the survey includes all costs, with VAT shown separately so you can see the full picture.
How long is the proposal valid for?
Proposals are typically valid for 30 days. Component prices can change, so we confirm pricing when you are ready to proceed.
