Have you been charged too much for gas?
Millions of people are being charged too much for gas because of faulty meters, it has been revealed.
A leaked report from National Grid shows one in six older gas metres in the UK is producing inaccurate figures in terms of gas usage.
The report showed if meters over-registered by 2%, the average family would have to pay £13 extra a year.
However, many of the meters were actually over-registering by more than this, pushing the average amount households were being overcharged up to £26 a year.
National Grid, which provides the majority of gas metres in the UK, tested the meters in 2007 and discovered the faults. But, two years later many of the metres had not been replaced.
The leaked report was not intended for the public.
The news comes as the last of the big six energy providers announced a price hike. EDF Energy, the last of the providers to introduce a hike, will up their prices on 2 March. Electricity rates will increase by 7.5% and gas rates by 6.5%.
British Gas, Scottish Power, Scottish and Southern Energy (SSE), E.ON and Npower have all previously introduced price increases.
If you have an older boiler you may have been over-charged for your gas. Check your bill and work out whether the figures seem to add up. If you have any doubts, contact your energy provider or speak to National Grid to find out if your meter can be replaced.
On its website National Grid Metering claims it is abiding by its commitment under the gas act 1995 to ensure that its gas meters are 'fit for purpose' and 'accurate'. If yours isn't you should be able to have it replaced.
