GAS bills are going up by 15% to 20%. Guernsey Gas yesterday announced tariff and standing charge increases of 5% from the beginning of next month.

But the fuel-cost adjustment will increase to 2.13p per unit.  ‘The tariff adjustment reflects the increase in our operating costs,’ said Guernsey Gas managing director Paul Garlick.

‘The fuel-cost adjustment, however, is as a result of record highs in the cost of crude oil, which has impacted on our LPG costs. Should global energy prices soften, we will reduce our tariffs.’

The company calculates that an average household gas bill could rise by £15 to £20 a month. The rise was announced by both Guernsey Gas and Kosangas and will affect both bottled and mains gas customers. The standard price of mains gas will rise to 13.98p per unit – the equivalent of one kilowatt hour – while Super Economy 24 will cost 8.78 or 9.52p per unit, depending on consumption.
