Basically, any worker whether employed or self employed can claim for travel and substance to a work place which is not their usual place of work. For a period no longer than two years.
An exception to this would be if the contract of work was for a set period of time (i.e. if the worker was employed for two weeks as cover for someone on holiday).
Construction sites by their nature are temporary.
Benchmark rates are rates set by HMRC, which if used mean that receipts are not required to be kept and produced (this does not mean that receipts cannot be kept and produced to claim greater amounts).
If you opt to use the Bencmark rates in any tax year, you cannot also use receipts to claim higher greater amounts.
Travel would either be by public transport and claimed by using receipts, or by private vehicle using either receipts for fuel or the Benchmark rate which includes a cost towards fuel, maintenance, repair, insurance, vehicle excise duty, etc.
Subsistence is dependant on time away from home.
For a period between 5 and 10 hours the rate is £5, over 10 hours the rate is £10.
If you have to start earlier than normal the early rate is £5 in addition to Any other rate claimed for that day.
If you work late, the late rate is £15 in addition to any other rate claimed for that day.
As such if your normal work times are between 07:30 and 16:30 and your travel time is 3 hours, you can claim £10.
If you are asked to start work at 06:00 on a particular day, you can claim £15 (£5 early rate & £10 day rate). You can claim this even if you leave work earlier than normal (at 15:00 perhaps).
The late rate can be claimed if you are asked to work late on a particular day.
The maximum you can claim for any one day is £30.
This does not apply to shift rota changes (i.e. if you rotate working days and nights).
Personally, I claim in full for phone and internet, along with computer and phone related accessories, despite personnel use. The cost is the same whether there is personnel use or not.
I also claim for cost of my Passport as I am required to produce either it or a copy when registering with agencies or occasionally on site at induction.
I claim for any courses that I take in relation to work, IPAF, PASMA, Abrasive Wheels, SSSTS, 2382, 2391, JIB/ECS card, etc.
I would also claim for any work related annual subscriptions such as the IET membership or NICEIC membership.
I also claim for a weekly service wash at a Launderette for my work clothes.
