Pricing and Deposit Information

• A £750 refundable deposit is required to begin the installation process and, where necessary, to submit your DNO (Distribution Network Operator) application.

In some cases, a new sub-board or RCD board may be required. If so, this will be quoted separately or charged on the day if installers need to purchase upgrade parts.

Optional Backup Power Upgrades

For properties in remote UK locations or where backup power is required, additional electrical components can be installed:

• Full house backup – With either automatic switchover or manual switchover, depending on system size and capacity.
• Critical load backup – Using the EPS output and a second consumer unit to supply essential circuits only (e.g. lighting, refrigeration, Wi-Fi, medical equipment).

Backup upgrade options are available on our installed packages page here. These can be added to your order after your deposit is paid, with payment only due once components are ready for installation.
