How does RIIO-3 affect my Energy Bill?

Should your energy prices need to be amended to reflect these new costs, we will notify any affected customers with details before this appears on your bill.

For example, by 2031, indicative network charge increases range from around £60 a year for a small holiday let or retail kiosk to £1,700 for small offices or hotels and £9,760 for a medium factory, reflecting differences in size and energy use. This is between 5% and 10% on electricity bills for a typical business before savings are considered. Crucially, as with households, the RIIO grid investments should deliver net benefits, through avoided constraint costs and lower wholesale prices.
