To ask for British Gas advice?

[MahMahMahMahCorona]

We are served by British Gas for electricity and gas. Today our current tariff expires and we have the opportunity to:

A) go fixed rate at £100pcm more than our current tariff expiring December 2023,
B) go variable with the proviso that they write to us 30 days prior to any price changes at which point we can switch, or
C) stick with our current tariff which will essentially mean an increase of £60pcm fixed until Jan 2023.

I don't know what to do. Which would you go for? Do you think the prices are going to increase by 40% in April, or more, at which time the fixed rates we've been offered today will also increase?

I'm so confused.

I took it from the British gas website so it's their figures.

I'm not going to try and work it out

I know, I’m just explaining that they change and why. I worked there for half a decade 😂
