Is your solar quote too expensive?
The headline figure cannot tell you on its own. A fair comparison needs to take account of system size, battery capacity, equipment, roof and scaffolding requirements and what is actually included.
We keep a clear line between what the document says, what we calculate and what still needs checking.
What to check
- Compare cost with system size
- Consider the battery separately where possible
- Check whether scaffolding and electrical work are included
- Compare equipment and warranties
- Look at the assumptions behind projected savings
Why solar quotes vary so much
System capacity is only one part of the price. Battery storage, hybrid inverters, multiple roof faces, access, monitoring, bird protection and electrical upgrades can all change the final cost.
A national average can be useful context, but it is not a property-specific valuation.
A better way to compare
QuoteCalm can work out simple figures such as price relative to system capacity, but it also looks at the equipment and what is included. As the quote dataset grows, comparisons can become more specific to genuinely similar UK systems.

Frequently asked questions
What is a normal solar panel price in the UK?
There is no single correct price. Energy Saving Trust's August 2026 solar guide cites around £7,600 for an average 4.5kWp home system, while another current Energy Saving Trust article uses around £6,100 for a typical system. Treat national averages as broad context, not a valuation of your home.
Does a battery make a quote much more expensive?
Usually. Energy Saving Trust's current battery guidance says battery storage systems typically cost around £5,000–£8,000, while another current roadmap example cites around £4,600 for an average 5kWh battery. Capacity, power, brand and installation work all matter.
We keep a clear line between what a quote says, what can be calculated and what still needs checking. We do not accept payment from installers to change the outcome of a quote check.
