A lot will depend exactly on what you are doing and where you are doing it.
Will you be actually in the UK at all?
Where will you be doing the work?
Are you Irish resident?
How many days will you spend in the UK? Will you become UK resident?
The above questions are relevant for Income Tax.
Re VAT - the limit in the UK is £70,000 over 12 months
You should really take professional advice, as the advice for each individual will vary depending on their individual circumstances.
