Often yes — if you wear a recognisable uniform or protective clothing for work, wash it yourself, and your employer does not provide laundry or reimburse you.
Think recognisable workwear you maintain yourself, not ordinary clothes you happen to wear at work. If a stranger could tell your job from the clothing, you are probably in claim territory.
Check whether your job has an agreed higher flat rate before claiming the standard amount — the difference adds up over four backdated years. Claims go through HMRC directly and are free to make; be wary of agents taking a cut for a form you can fill in yourself. See more in all guides.
