Electricity meters

Usually the dwelling uses either the standard domestic tariff (single meter) or an off-peak tariffs (dual meter) in these cases select single or dual meter and an addendum is not required.

In some cases of older installations the property may have two separate single rate metres present and it is unclear whether Dual meter or single meter should be identified.

if that applies:

If the main space heating is electric select dual meter if the main space heating is an off-peak electric device and single meter otherwise direct acting heaters

If the main space heating is not off-peak electric but the water heating is electric select dual meter if it has a dual immersion and single meter if it has a single immersion

If neither of the above applies select single meter

And

If dual meter selected include addendum 10

If single meter selected include addendum 11
