- The individual works sufficient hours in the UK, as assessed over a period of 365 days;
- During that period there are no significant breaks from UK work;
- All or part of that period falls within the relevant year;
- More than 75 per cent of the total number of days in the 365 day period on which he works more than three hours are days worked in the UK; and
- At least one day in the relevant year is one in which the individual works more than three hours in the UK.
There are instructions as to how to identify, for any given period of 365 days, whether the individual works 'sufficient hours' in the UK:
- Eliminate the days is which he works more than three days abroad. These are ‘disregarded days’.
- Next, add up the total number of days the individual works in the UK, ignoring ‘disregarded days’.
- Now subtract from 365 (disregarded days + any days where there were gaps in employment); this is the ‘reference period’.
- Divide the reference period by seven, rounding down to the nearest whole number.
- If the answer is 35 or more, the individual is considered to work ‘sufficient hours’ in the UK in the 365-day period.
This does not apply if the individual has a relevant job aboard a vehicle, aircraft or ship at any time in the year and at least six trips in the year as part of the job are cross-border trips that either: begin in the UK, end in the UK or begin and end in the UK.
