In a poll of more than 550 business leaders, 53 per cent blamed energy company profits for price rises, which the CBI said indicated a lack of trust in the market.
Just under half – 47 per cent – of business leaders interviewed think more competition is the best way to keep future bills down.
“Long-term certainty is needed but just as policies start to click into place, the political climate heats up again,” CBI deputy director-general Katja Hall will tell the business group’s energy conference today.
“One careless comment or populist proposal – whether we’re talking about cutting support for onshore wind farms or freezing energy prices – can make businesses feel like they’re right back at square one.
“For investors, this is a real worry. And when that investment can go anywhere in the world, it should be a real worry for politicians too.”
