Very little impact. Any indy that has not learned by now how to income shift , well...less said the better.
As I get longer in the tooth it brings the benefit of realising that all wealth and income is relative. Before and after the budget, my relative position (in purely financial terms) is unchanged and as such my lifestyle in relative terms will be unchanged.
In terms of winning work, I'd have to say exactly the same. As mentioned above, when companies cut costs they all too often get consultants involved to tell them how to do it. This goes for the private sector as well as public.
Final point - as an educated, flexible, worker macro-economics impact your quality of life by 10% max. Your own activity can create outcomes that are entirely counter-cyclical to the economy. I've seen three or four major downturns now. I did have a dull time during one, but during two I got promoted, earned bonuses and had a great time.
I am of course aware that after some budgets there are people who find themselves 23 quid worse off a week and can only balance the books by buying less baby food. I'm just saying that I don't believe many of them are management consultants.
