How much do solar panels cost in the UK?
It depends on the number of panels, the inverter, whether a battery is included and how easy the roof is to reach. Below: what drives the price, how VAT applies and how to read a solar quote properly.
The key points
- Our confirmed package includes panels, a hybrid inverter, a battery and scaffolding to one elevation
- Power-cut backup is a separate gateway
- System size should follow your usage and roof
- Access, roof type and electrics can change the price
- A good quote shows modelled generation and every warranty
The short answer
The price of solar depends on how many panels, the inverter, whether a battery is included, and how easy the roof is to reach. Our current fully installed solar and battery package is £6,250: up to 8 panels, a hybrid inverter and a 5.12 kWh battery. Includes standard installation and scaffolding to one elevation. Additional scaffolding or non-standard access will be assessed and quoted separately before you commit. Final specification and price are subject to technical assessment. 0% VAT currently applies to eligible domestic installations until 31 March 2027; scheduled to rise to 5% from 1 April 2027.
What’s in that price
- up to 8 solar panels (make and model depend on stock; the final number is agreed after assessment)
- a hybrid inverter, which can run panels and a battery together
- a 5.12 kWh battery
- scaffolding to one elevation and full installation
It doesn’t include power-cut backup, which needs a backup gateway at from £1,295. Solar, battery and backup together is from £7,545. See power-cut backup.
What changes the price
- System size. More panels cost more in total but usually less per panel. Size should follow your usage and roof, not the biggest number that fits.
- Battery or no battery. A battery is a significant part of the cost and isn’t always worth it; see do you need a battery?
- Access and scaffolding. One elevation is included; extra elevations, tall buildings or awkward access cost more and are quoted before you commit.
- Roof type. Slate, flat roofs and in-roof mounting cost more than standard tiles.
- Electrics. An older consumer unit may need upgrading.
- Equipment tier. Different inverter and battery brands carry different prices and capabilities; see Hanchu vs Fox ESS vs Sigenergy.
VAT
0% VAT currently applies to eligible domestic installations until 31 March 2027; scheduled to rise to 5% from 1 April 2027.Will it pay for itself?
The return depends on how much you generate (see Do solar panels work in Yorkshire?), how much of it you use rather than export, your electricity price and your export tariff. We model this for your roof and usage and show the assumptions, rather than quoting a headline payback period.
Reading a quote
A good solar quote shows modelled generation for your roof, the exact equipment, every warranty, what’s included in scaffolding and electrics, and what could change after the survey. Be wary of round-number savings and prices that only hold “today”.
