Installation Requirements:
Our battery storage installation price is based on a simple, standard installation where the battery system can be fitted in an easy-access location, such as a garage, utility area, plant room, or another suitable ground-level location close to the existing electrical connection point.
To keep the installation straightforward and within the advertised price, the following conditions must apply:
- The battery storage system must be installed no more than 10 metres from the connection point.
- The cable route must be simple and accessible.
- Cables must not need to pass through roof spaces, loft spaces, or difficult-to-access areas.
- Cables must not run across paths, driveways, walkways, or areas where additional protection, trenching, or specialist routing would be required.
- The installation must be a direct and straightforward connection from the consumer unit or agreed connection point to the battery storage system.
- The installation area must be suitable, safe, dry, and accessible for the equipment and installer.
This standard installation price is intended for simple installations only. If the installation is more complex, requires longer cable runs, additional electrical work, cable protection, difficult routing, trenching, external works, or alterations to the existing electrical system, additional costs may apply.
Once your order has been placed, we will review the installation details with you before confirming the final installation arrangement.
