BRITAIN is “critically vulnerable” to another energy crisis that would see prices spike again, a commission has warned.

The Energy Crisis Commission (ECC), which includes representatives from Citizens Advice and Energy UK, found that Britain was “dangerously underprepared” for the energy crisis, and was one of the worst-hit countries in Europe. 

It said there had been sluggish progress in upgrading housing stock, delays to new-build efficiency standards and missed opportunities to expand renewable energy projects, for which bill payers paid the price.
