Tax spreadsheet and allowable expenses for Window Cleaners (UK sole traders)

These are common examples. A cost is allowable only if it is wholly and exclusively for your business, so check GOV.UK guidance on expenses if you are self-employed, or ask an accountant.

• Ladders and poles may be allowable
• Water-fed pole kit may be allowable
• Van or mileage may be allowable
• Insurance may be allowable
• Cleaning supplies may be allowable
• Business share of phone may be allowable

• Using both simplified mileage and actual vehicle costs for the same vehicle.
• Combining business and personal van or phone use in one record.
• Leaving equipment purchase or maintenance records apart from job paperwork.
• Not keeping public liability insurance details with renewal documents.

• Invoices and receipts for ladders, poles, water-fed equipment and its upkeep.
• Public liability insurance policy details and renewal paperwork.
• Receipts for cleaning supplies and other job materials.
• Mileage log with date, destination, purpose and distance.

Keep receipts, invoices and mileage details as you work, and record business and personal use separately where needed. Organised records make it easier to prepare your Self Assessment return.
