Overnight Trips & Accommodation: Claiming Travel Costs as a Sole Trader

The Golden Rule: Wholly and Exclusively

Every travel and subsistence claim you make as a sole trader must pass HMRC's wholly and exclusively test. This means the expense must be incurred entirely for business purposes. If there's a personal element — even a minor one — HMRC can disallow the whole claim, unless you can clearly apportion the costs between business and personal use.

This rule catches out a lot of freelancers. A working trip to Edinburgh where you spend an extra day sightseeing? The business nights may be fine, but the leisure night is not deductible. Keep that separation clear in your records.

When Can You Claim Overnight Accommodation?

You can claim the cost of a hotel, guesthouse, or other accommodation when you genuinely need to stay away from your usual place of work or home for business reasons. Common valid scenarios include:

• Travelling to a client's site that is too far to return from in a single day
• Attending a multi-day conference or industry event directly related to your trade
• Working on a project in a different city for a fixed, temporary period

HMRC expects costs to be reasonable. There's no hard spending limit, but a £400-per-night luxury hotel when a £90 business hotel would do the job is likely to attract scrutiny. Claim what is reasonable for the circumstances.

Meals and Subsistence on Overnight Trips

When an overnight stay is required, you can also claim the cost of meals eaten during that trip. This is different from day-to-day meals — HMRC does not allow sole traders to claim lunch at their desk or near their regular workplace, because eating is a personal need regardless of where you are working.

However, when you are away overnight on a genuine business trip, meals become a legitimate subsistence expense. Keep all receipts, and be sensible about amounts. Alcohol is generally not deductible unless it forms part of a genuine business entertainment cost (which itself has restrictions).

Travel to and From the Overnight Location

The cost of getting to and from your temporary work location is also deductible. This includes:

• Train, coach, or bus fares
• Flights for longer-distance trips
• Mileage if you drive your own vehicle (using HMRC's approved mileage rates: 45p per mile for the first 10,000 miles, 25p thereafter)
• Taxis to and from stations or airports where reasonable

If you drive, you cannot claim actual fuel costs separately — the approved mileage rate covers fuel, wear and tear, and insurance for business journeys.

What You Cannot Claim

There are clear boundaries. You cannot claim:

• Travel from home to your regular, permanent workplace — this is ordinary commuting and is never deductible
• Accommodation costs for a partner or family member travelling with you
• Personal upgrades, such as paying extra for a first-class seat when a standard ticket would suffice, unless there is a clear business justification
• Any portion of a trip that is personal in nature

Record-Keeping Is Everything

HMRC can ask you to justify any claim, so your records need to tell a clear story. For each overnight trip, keep:

• The date, destination, and purpose of the trip
• Receipts for accommodation, meals, and travel
• A note of the client or business reason — a simple diary entry or email confirmation works well

Digital tools and expense apps make this straightforward. The moment you book a trip is the best time to log the business purpose, before the details fade.

A Quick Sense Check Before You Claim

Before including any overnight expense in your Self Assessment tax return, ask yourself: Would I have incurred this cost if I were not running my business? If the honest answer is no, the claim is likely valid. If you would have made the trip anyway, or if personal enjoyment was a significant factor, tread carefully and apportion accordingly.
