It's businesses I'm particularly worried about.
We work in this market and I've just been dealing with one where the wholesale price has increased by a factor of 13 from when their last contract was signed. Roughly looking at a year ahead wholesale increase from 5p per kWh to 65p. It's not sustainable, many businesses will simply go under.
Craziest thing is, the competitiveness (and therefore survival) of many businesses could be determined by random luck. If you signed a multi-year fixed agreement last year, you're laughing. If your fixed agreement is ending soon, you're in trouble.
Imagine two cafés on the same street. One locked in a three year deal last year. The other has just seen its fixed deal expire. The first has, say, a £15k/year energy bill, while the latter is having to stump up £75k. That's an extra £60k/year in costs, on top of all of the other rising costs. How on Earth does the second café remain competitive with the first?
