I'll be putting my prices up in April if not sooner.
You just can't keep them the same. The cost of literally everything has gone up.
My gas and electric has gone up nearly 200 quid a month, my mortgage will be doing the same. There's 400 quid a month before I've even started on council tax and other bills not to mention business costs like fuel, water , insurances. Corporation tax has gone up as has the dividend rate.
I've not actually sat down and calculated exactly but as you can see it's pretty scary if you think you are going to keep your prices and income the same.
My prices will be going up, if they don't like it they will have to be replaced it's that simple.
