Normally the cost of cleaning workwear is tax deductible for an employee or self-employed person.  This is particularly the case where the provision of the clothing or workwear is tax deductible also.  The cost of normal clothing however, including gents and ladies suits, is not deductible, whether or not they are used  solely for work purposes.

Dependent upon the type of industry that an employee works in, there are scale rates that HMRC publishes which they will accept as being a reasonable cost for maintaining protective clothing and uniforms.  No such round sum allowances exist for the self employed, who should claim the actual costs involved, unless they have negotiated something to the contrary with HMRC.
