What Expenses Can I Claim as a Small Business in the UK

When you’re running a small business, every penny counts. Claiming the right expenses can reduce your tax bill, boost your profit, and give you more financial breathing space. But what counts as a “business expense” — and what doesn’t?

At Zenith Bookkeeping, we’ve helped hundreds of small business owners across the UK get clarity on their costs. Here’s a quick guide to help you confidently claim what’s yours.


1. Office and Home Working Costs

You can claim for:

  • Office rent or shared co-working spaces

  • Utilities (a portion, if you work from home)

  • Business broadband and mobile phone use

  • Office supplies (paper, pens, printer ink)

Tip: If you work from home, use HMRC’s simplified flat rate or calculate the actual proportion of use.


2. Travel Expenses

You can claim for:

  • Business mileage (cars, vans, bikes)

  • Train, bus, or taxi fares

  • Parking fees (not fines!)

  • Accommodation for overnight business trips

Tip: Keep a mileage log — apps like MileIQ can help automate this.


3. Marketing and Subscriptions

You can claim for:

  • Business cards, flyers, and advertising

  • Website costs (domain, hosting, web design)

  • Social media ads and consultants

  • Relevant software (Xero, Canva, Microsoft 365)


4. Professional Services

You can claim for:

  • Accountant or bookkeeper fees

  • Legal or business advice

  • Business coaching and training courses


5. Staff and Payroll Costs

You can claim for:

  • Employee wages

  • Employer NI contributions

  • Staff uniforms or PPE

  • Subcontractor fees (registered properly)


6. Equipment and Assets

You can claim for:

  • Computers, laptops, and tablets

  • Furniture used in your office

  • Tools and machinery (depending on your trade)

Tip: Large purchases may need to be claimed as capital allowances — your bookkeeper can help with this.


🚫 What You Can’t Claim

  • Personal items (even if used “a bit” for work)

  • Client entertainment (e.g. meals out — sorry!)

  • Daily commutes to a regular workplace

  • Fines and penalties
