What indicative price ranges can I expect?
The figures below are indicative ranges for typical system configurations installed at 0% VAT in October 2026. Your actual quote will depend on the factors discussed below and is confirmed after a no-obligation survey at your home. No single online figure can be accurate because every property is different.
| System | Indicative range (installed, 0% VAT) |
|---|---|
| Home battery 5 kWh only | £3,500–£4,500 |
| Home battery 10 kWh only | £5,500–£7,000 |
| 4 kW solar + 5 kWh battery | £8,000–£11,500 |
| 6 kW solar + 10 kWh battery | £12,500–£18,500 |
Figures are indicative ranges for October 2026 and include supply and installation at 0% VAT (0% VAT ends 31 March 2027). Actual quotes vary by property.
What factors drive the cost in 2026?
Six main factors account for most of the variation in price between one installation and the next. Understanding them helps you see exactly what you are paying for when you receive your quote.
System size (kWp)
The single biggest factor is the size of the solar array, measured in kilowatt-peak (kWp). A larger system with more panels generates more electricity but requires more panels, mounting equipment and labour. The right size depends on your roof area, your daytime electricity use and how much of your consumption you want to cover. The survey assesses your roof and usage to recommend an appropriate system size.
Roof type, orientation and condition
A straightforward south-facing roof at a typical pitch is the simplest scenario. Roof pitch, orientation, roofing material (concrete tiles, slate, flat roof membrane) and whether the roof structure needs attention all affect the price. Slate roofs can take more care to work on than concrete tile. A complex roof with dormers or Velux windows may require more time and mounting equipment.
Battery storage capacity
Adding battery storage lets you store surplus solar electricity for use in the evening and overnight. Battery capacity is measured in kilowatt-hours (kWh). A larger battery stores more energy but costs more. The right capacity depends on how much surplus your system is likely to generate and your evening usage. You can choose solar panels only, solar with a battery, or battery storage only.
Inverter type
The inverter converts DC electricity from your panels into AC your home uses. A single string inverter or microinverters fitted to individual panels both affect cost and performance. If your roof has shading from chimneys or neighbouring buildings, microinverters or an optimised string inverter may be recommended.
Scaffolding and access
For most two-storey homes, scaffolding is a standard part of the installation and is included in your quote. The amount depends on roof height, how many elevations need scaffolding, and how easily it can be erected at the foot of the building.
Installation labour and complexity
The labour element covers fitting the mounting system, installing panels, fitting the inverter, running cabling and connecting to your consumer unit. A straightforward installation on an accessible roof is quicker than one involving a complex roof or a consumer unit upgrade. Any such requirements are identified during the survey.
How does 0% VAT affect the cost in 2026?
Until 31 March 2027, 0% VAT applies to the supply and installation of qualifying solar panels and battery storage. This means the prices you see in your quote do not have VAT added on top, which is a meaningful saving compared to the standard 20% rate. If you are planning a solar installation, completing it before the 0% VAT period ends is worth bearing in mind. Interest-free credit up to £30,000, subject to status.
Can I spread the cost monthly?
Yes. Interest-free credit up to £30,000 is available, subject to status. This lets you spread the cost of your solar and battery system over time without paying interest. The exact terms depend on your individual circumstances and are discussed after your survey. For more detail on finance options, our sister site Solar Finance Scotland covers paying monthly with interest-free credit in depth.
How do I get an accurate price for my home?
Because the cost depends on the specifics of your home, an accurate quote requires a no-obligation survey. An installer visits your property, measures the roof, checks orientation and pitch, assesses shading, inspects your electrical setup, and discusses your usage. You then receive a written, no-obligation quote that reflects your home. Use the form on this page to arrange yours, or see our full cost guide for more detail on each factor. The full process is explained on our How It Works page.

Frequently asked questions
Is 0% VAT still available on solar panels in 2026?
Yes. 0% VAT on the supply and installation of qualifying solar panels and battery storage runs until 31 March 2027. This means any system installed before that date benefits from the reduced rate.
Can I spread the cost of solar panels in Scotland?
Yes. Interest-free credit up to £30,000 is available, subject to status. This lets you spread the cost of your system over time without paying interest on the balance.
Why can I not get an exact price online?
Because every home is different. The size of system you need, your roof, your battery requirements and access to your property all affect the cost. An accurate quote requires a no-obligation survey at your home.
Does adding a battery increase the cost significantly?
Adding battery storage increases the upfront cost compared to panels alone, but it lets you use more of the electricity your panels generate. A 5 kWh battery typically adds £3,500–£4,500 and a 10 kWh battery £5,500–£7,000 to the system cost.
Are these prices guaranteed?
No. The figures are indicative ranges for typical configurations installed at 0% VAT in October 2026. Your actual quote depends on your property and is confirmed after a no-obligation survey.
