Change existing supply
Do you need to amend an existing power supply? You’ve come to the right place.
Please select this option if you would like to amend an existing supply (for example, underground conversion, increasing capacity, sub-main works or maintenance) or if you require a quotation for an entirely new separately metered supply.
Our connectivity forms require a good understanding of the network around you as well as electricity terminology. Applications have a higher success rate and faster processing times when they are completed by someone with technical understanding.
Due to current demand, it can take up to 40 working days (8 weeks) from the payment of the application and design fees to process a network-approved design and quote (depending on the service required).
To secure construction dates, please accept your quote as soon as possible. Please be mindful that jobs are given priority in order of acceptance of the quote.
