Get Solar & Battery Power

Before going ahead with your installation, we'll need to make sure of a few things first. Firstly you will need a clear space on a pitched (not flat) roof that can fit at least 4 solar panels. See our FAQ on how much space you'll need for more info.

It's important that this part of your roof sees the sun throughout the day, so a north facing roof may be unsuitable. We'll also need to be able to install scaffolding below this part of the building in order to complete the installation.

Next, you'll need to decide if solar panels make money-sense. The higher your energy usage at home, the more beneficial solar panels and a battery will be (you'll be saving the money you would have otherwise spent on bills, and this will go towards paying back the cost of your solar system). If you have a low usage, it's worth keeping in mind that your payback period will be longer, but this is something we can discuss in your consultation.

Finally, it's worth keeping in mind that we can't install on properties with a 3 phase electricity meter just yet, but we are working hard on a solution.

Fill out our quick online form. We’ll send over a personalised quote within 1 working day, with a price that covers everything you’ll need for a standard solar and battery installation. We'll then take a £500 advance payment (fully refundable until the day before scaffolding installation).

Next our Solar Design Specialists will work with you to design the ideal system for your home, using state-of-the-art software to visualise the path of the sun and where to best position your solar panels. You’ll have the option to change the design to fit your budget, and remove the battery if you choose to.

We'll ask you to fill out a remote survey form to ensure your solar design is spot-on before installation. If you're not able to complete the remote survey, we will arrange a date for a surveyor to visit your property.

Finally we'll find a suitable date for your installation. Installation should take 2-4 days, depending on the size of your system. We will also schedule time on either side of this to put up and take down the scaffolding at your property. Once installation is complete, we’ll request the remainder of the total cost.

We’ll be here to answer any questions or concerns that you have throughout the process, and our aftercare team will be available by phone 7 days a week once your installation is complete.

Average cost

The cost of installation can depend on how many panels you need, whether you choose to have battery storage and what size of battery you require. The cost of a panel-only installation by Octopus starts from £4,999 (for 4 panels). A 10 panel installation and a 5kWh battery (our most popular system) costs £10,399.

How long will it take for my solar system to pay for itself?

We compared the typical installation cost and annual bill savings for our most common solar system (10 panels, 5kWh) in 5 different scenarios. The payback period varied from 9 - 12 years depending on the energy tariff.

Of course, each home is unique and this can be influenced by lots of different factors.

We’ll calculate a personalised payback period following our design consultation to give you an insight into what you might save for your home.

Our equipment is guaranteed with the following manufacturer warranties:

• PV Solar Panels: 25 years product warranty and 30 years linear power warranty.
