Electricity Act 1994

A receiver may, at any time—

elect, by written notice given to the relevant on-supplier, to have the receiver’s consumption of electricity supplied from the on-supplier measured by a meter; and

have the meter installed, at the receiver’s expense.

However, the election has effect only if the installation is done in a way—

that complies with any reasonable written directions the on-supplier gives the receiver within 5 business days after the giving of the notice; or

if no written directions are given within the 5 business days—that is reasonable.

In deciding what is reasonable for subsection (2), regard must be had to the interests of the on-supplier and anyone who is an occupier of the on-supplier’s premises.
