An exclusive gated community in Cobham, Surrey, has the highest annual gas bills in Britain, data shows. 

Owners of properties at Fairmile Court in Cobham typically pay £3,596 a year for their gas bill, according to the comparison website Uswitch. 

This figure does not include electricity, which costs about £666 per year for an average household, not including standing charges. 

The data suggests residents in Fairmile Court have higher energy bill costs because the detached six-bedroom-plus homes often have a floor area of about 424 square metres, five times more than the 94 square metres most households across Britain have. 

By contrast, the average annual gas bill is approximately £660. This is £2,936 less than residents in Fairmile Court, where you would be hard-pressed to find a property on the market for less than £2million, generally pay.

Residents typically use nearly 63,000kWh of gas a year in the close, more than five times the national average.

Uswitch said the average home uses 11,900kWh of gas, with more than two-fifths, or 44 per cent, of households using more than Ofgem’s medium-use figure of 11,500kWh. 

According to the analysis, streets in London and Surrey comprise eight of the ten streets with the highest average gas bills.

At £3,491, residents in Lansdowne Crescent, Holland Park, London, are shelling out the second highest sum for their gas bills each year. 

Rosebriars, a private road in Esher, Surrey, has the third highest gas bills in Britain, with residents stumping up £3,439 a year on average. 

Homeowners on Barton Drive in Beaconsfield, where homes typically sell for at least £2million, are also paying a hefty £3,367 for their annual gas bills on average  

Scotland’s largest average gas bills can be found on Elphinstone Road in Glasgow, where the average is £3,373. 

Meanwhile, residents paying the largest gas bills in Wales can be found in Maes Deri in Deeside, Flintshire, with households paying £2,813, more than four times higher than the national average.  

Scrutinising wider postcode areas reveals that Surrey and Buckinghamshire top the table for higher heating bills, taking three slots in the top ten each. Ponteland in Northumberland, Kilmacolm in Renfrewshire, Scotland, and Golders Green in London make up the rest of the list. 

Typical annual household energy bills could increase by £332 in July, energy consultancy Cornwall Insight has predicted.

The forecast reflects the surge in gas and oil prices as war in the Middle East continues. The forecast could increase further or drop, depending on where energy prices go next.

Energy regulator Ofgem will set the July cap on energy bills for households on 27 May, based on wholesale prices in March, April and May.

The cap sets a maximum price for each unit of gas and electricity and is updated every three months. Actual bills depend on the amount of energy households or businesses use. 

Cornwall Insight's latest forecast predicts that, under Ofgem's price cap for July to September, a dual-fuel household using a typical amount of gas and electricity would pay £1,973 a year, up from the current £1,641.

Ben Gallizzi, an energy expert at Uswitch.com, said: 'The cost of heating is headline news once again, with eight in 10 households worried their energy bills will soar.

'Customers currently on fixed deals are protected as their rates are locked in for the duration of their fix, but customers on standard tariffs could see their costs go up dramatically if the price cap increases in July as predicted.'

He added: 'You can’t control global events, but you can take action to protect yourself from higher winter bills. Fixing your energy rates now is the only way to avoid hefty price hikes that are predicted to come our way.

'While the price of fixed deals has increased, it’s a reasonable move to pay a little more to protect your rates for at least a year in the current circumstances, and there are still 25 tariffs available.'

Government support with energy bills pushed up by the Iran war would be based on household income, Rachel Reeves told the BBC this week.
