Economy 7 Electricity

'Economy 7 electricity' is commonly installed in areas around the UK where gas is not practical or cannot be supplied. High-rise flats in built up metropolitan areas and local authority housing developments for example have high usage of economy 7 electricity. It also solves gas accessibility issues in rural areas and allows for a cost effective alternative to on peak electricity.

People install economy 7 electricity primarily for economy 7 storage heaters although it's also practical for other household appliances which can be used during the off peak period.

With economy 7 electricity installed as an energy source there tends to be fewer engineer call outs, lower maintenance costs and generally less problems in the future. Compared to gas central heating which can require expensive pipe work especially if there will be alterations to the property.


The best way to compare both tariff's is to go on to the internet searching for 'electricity tariffs'. You should then be able to access all the tariffs promoted by electricity companies and compare current rates. There are genuine discounts for using off peak economy 7 electricity tariffs.

When you sign up for off peak economy 7 electricity the whole house goes on to the cheap rate so you can further benefit by using your washing machine, dishwasher or tumble dryer overnight.

Historically off peak users were charged a premium for the normal supply but this was only approx 0.5p more than the general domestic rate. This may not even be the case in today's competitive pricing structures. Clearly this argument is a bit of a red herring if the running costs using off peak heating are competitive.
