I assume it's because u might be on an emergency tax code, as they have no
"history" of you.
(.... although some of the deduction might be National Insurance contributions).
If it's tax, u should be able to claim most of it back.
The tax year in the UK runs from 1April - 31 March, and a single person can
earn £6,475 per year before paying tax.
So, if you've earned under that, you'll get it back
(But u MUST claim it !)
If you've earned for eg £8,000 in the tax year,
your tax will be £8,000 - £6,475 @20% = £305
(,.... and obviously, if you've paid more, u claim a refund)

& tax allowances.
