Why Being an Octopus Trusted Partner Matters
It matters because you know you're in safe hands. We've been selected, vetted and monitored by Octopus Energy for safety, quality and customer service. The badge isn't bought, it's earned and kept.
Independent companies selected, vetted and monitored by Octopus Energy against safety, quality and customer-service standards. Not Octopus employees.
When Octopus Energy can't deliver an installation directly, they introduce customers to vetted independent installers like us. You're always free to choose any installer.

Your Questions, Answered
Most systems cost between £6,000-£12,000, depending on your roof, your energy use and the battery you choose. We confirm the exact price with a free survey — and the price we confirm is the price you pay.
Most homes in Scotland are suitable for solar panels. Key factors include the direction your roof faces (south is ideal, but east and west can also be effective), available roof space, and shading from nearby trees or buildings. We provide a free, no-obligation survey to show you what's achievable.
Most installs are completed in a single day, and larger projects can take a little longer. Our lead time is usually between 4 and 6 weeks — we'll confirm our next free installation slot when we connect.
We use solar panels that are specifically designed to thrive in the UK climate to ensure you're making electricity even when it's cloudy. Add battery storage to keep running on stored energy when it's dark.
