Homes in Bolton are being offered an exclusive green energy deal, backed by renewable electricity generated in the North West of England.

The tariff, which is limited to the first 1,000 Greater Manchester homes to apply, is from Octopus Energy, one of the UK’s fastest growing suppliers, and can save a typical Greater Manchester home £272 a year.

Residents can access the deal, which is backed by Greater Manchester Combined Authority (GMCA), at

The exclusive deal is only available until 17 April.

Green energy experts Big Clean Switch, who negotiated the tariff for the GMCA, say the Octopus deal combines low cost green energy with the supplier’s award winning customer service.

Octopus is the only UK energy supplier to have been named as a Which? recommended provider for the last two years running.

Every unit of electricity used by homes on the tariff will be matched by power generated at a wind farm in the North West of England - High Pow Wind Farm in Wigton, Cumbria. 

Big Clean Switch Managing Director Jon Fletcher said: “This tariff gives residents of Greater Manchester an easy way to buy green energy that is both affordable and supports the region’s growing renewables industry.”  

As well as all 10 Greater Manchester local authorities, a host of other organisations from across the city including football clubs, universities and businesses are backing the Greater Manchester Big Clean Switch campaign, the first of its kind in the UK.

About the savings estimate

Savings figure compares the cost of supplying a medium consumption dual fuel home with energy for 12 months on Octopus’ GM Green Switch tariff (£976.00) versus the average Big Six standard variable tariff (£1,248.30) for the North West electricity region.

Big Six standard variable tariffs are accurate from 1 April 2019, when the new Ofgem price cap comes into effect. For more information on the price cap, see

About the GM Green Energy Campaign

The new scheme is a partnership between the Greater Manchester Combined Authority and Big Clean Switch, which specialises in helping UK households and businesses switch to 100% renewable electricity.

The programme is funded through commission paid by suppliers.

This doesn’t affect the tariffs available, which are the same price as they are on suppliers’ own websites. Half of the money will be used by the GMCA to help fund environmental projects across the region.

As part of the campaign, there will be exclusive green energy tariffs made available to residents and businesses of Greater Manchester. The residential green tariff launched on 26 March, with the business green tariff available in April. You can register your interest in hearing about either of these tariffs by going to

About green tariffs

When a home is on a green tariff, the supplier guarantees that every unit of electricity used by the home is matched by an equivalent unit of renewable electricity that has been supplied to the National Grid. The more homes on green tariffs, the greener the Grid will get.
