UK Travel Expenses: What Can Sole Traders and Limited Companies Actually Claim?
Business rarely happens in one place. One day you are driving to meet a client, the next you are visiting a job site, and by Friday you may find yourself on a train to Manchester wondering why the only coffee available costs roughly the same as a small business loan. Travel costs have a habit of looking insignificant individually, but over the course of a year, mileage, parking, train tickets, taxis, hotels and business trips can add up to a surprisingly substantial amount.
So the important question is: which travel expenses can you actually claim as a business expense in the UK?
Whether you are a Sole Trader or run your business through a Limited Company (LTD), legitimate business travel can reduce your taxable profit or be reimbursed under the relevant HMRC rules. The key word, however, is business. HMRC is interested in why the journey was made, not how creatively it was described in your bookkeeping.
When does a journey count as business travel?
A genuine business journey could include travelling to meet a client, visiting a temporary workplace or job site, travelling between clients, attending a business conference or training course, or making another journey that is necessary for your work.
Depending on the circumstances, allowable travel costs can include business mileage, train and bus fares, taxis, flights, parking and accommodation required for an eligible business trip.
Where things become more complicated is the journey between home and your normal place of work. If you leave home every morning, travel to the same office and return home in the evening, that journey will generally not become an allowable business expense simply because work happens at the other end of it. For employees and Limited Company directors, HMRC normally treats travel between home and a permanent workplace as ordinary commuting.
The position for Sole Traders can be different, particularly where the nature of the business involves travelling between numerous locations rather than working from one permanent base. A builder, engineer, installer or other tradesperson, for example, may regularly work at different sites while genuinely running the administrative side of the business from home. HMRC recognises what it calls itinerant trades, and in appropriate circumstances travel from home to different temporary work locations can qualify as business travel.
This does not mean that simply keeping a laptop on the kitchen table automatically turns your house into a business headquarters. As with most tax rules, the actual facts matter.
There is also no magic distance at which a private journey suddenly becomes a business journey. A client does not need to be 10, 20 or 50 miles away from your home before mileage can qualify. HMRC looks at the purpose and circumstances of the journey, rather than applying a minimum mileage rule.
Imagine, for example, that you genuinely work from home and drive across town specifically to meet a client at a café to discuss a project. Depending on the circumstances, that can be a business journey. But if you normally commute to the same permanent workplace and arrange a quick client meeting conveniently along your usual route, that does not necessarily transform the entire commute into allowable business travel.
Putting “CLIENT MEETING” in capital letters in your calendar is useful organisation. It is not, unfortunately, a tax rule.
Business mileage: the simpler way to deal with vehicle costs
Vehicle expenses are an area where bookkeeping can become unnecessarily painful. Fuel, insurance, servicing, repairs, tyres and general running costs all need to be considered, and by the end of the year it can be difficult to remember whether a particular petrol receipt belonged to a client visit or Saturday’s trip to IKEA.
For eligible Sole Traders, HMRC’s simplified expenses system can provide a much easier alternative. Instead of calculating the business proportion of actual vehicle running costs, you can record your qualifying business mileage and use HMRC’s flat mileage rates.
There is an important change for the 2026/27 tax year. From 6 April 2026, the simplified mileage rate for cars and goods vehicles is 55p per business mile for the first 10,000 miles in the tax year and 25p per mile after that. Before 6 April 2026, the rate for the first 10,000 miles was 45p, so older articles and online calculators may still show a figure that is now out of date.
Suppose you drive 12,000 qualifying business miles during the 2026/27 tax year. The first 10,000 miles at 55p would give you £5,500, while the remaining 2,000 miles at 25p would give you another £500. The total calculated using the mileage method would therefore be £6,000.
It is worth remembering that the mileage rate is not simply a petrol allowance. It is designed to cover the costs associated with using the vehicle. You cannot normally use the simplified mileage rate and then add the same vehicle’s fuel, insurance, servicing and repair costs on top. Certain separate business travel costs, such as parking or public transport, may still be claimed where the relevant conditions are met.
There are also rules around when the simplified mileage method can be used. For example, if you have already claimed capital allowances for that particular vehicle, you cannot simply switch over and use simplified mileage for it. Once the flat-rate method is adopted for a vehicle, HMRC generally requires you to continue using it for that vehicle while it remains in the business.
What if you are a Limited Company director using your own car?
If you run a Limited Company and use your personally owned car for qualifying business journeys, your company can reimburse you using HMRC’s Approved Mileage Allowance Payments.
From 6 April 2026, the approved rate for cars and vans is 55p per mile for the first 10,000 qualifying business miles and 25p per mile thereafter.
If the company reimburses you within the approved HMRC amount and the journeys qualify, the payment can generally be made without treating it as normal taxable salary. If the company pays more than the approved amount, the excess can create tax and reporting consequences. If it pays less, the employee or director may in certain circumstances be able to claim Mileage Allowance Relief on the difference.
Whatever method you use, keeping a proper mileage record is one of those small habits that can save a considerable amount of trouble later. Record the date, where you travelled from and to, the business reason for the journey and the number of business miles travelled.
Trying to remember nine months later why you drove 86 miles on a rainy Tuesday in November is not a particularly reliable accounting system.
What about meals, subsistence and daily allowances?
This is an area where Sole Traders and Limited Company directors are often incorrectly treated as though the same rules apply to everyone.
For a Sole Trader, simply working away from home does not automatically mean you can pay yourself a fixed daily food allowance. HMRC generally regards ordinary meals as a personal cost because, inconveniently for tax planning purposes, human beings need to eat whether they are working or not.
There are exceptions. Reasonable meal costs may be allowable in certain circumstances connected with qualifying business travel, including some overnight business trips and situations where the nature of the trade itself involves travelling from place to place. The precise circumstances matter, so it is dangerous to assume that every lunch bought while working automatically belongs in the business accounts.
For employees and directors of Limited Companies, HMRC has Benchmark Scale Rates that can be used where the qualifying conditions are satisfied. Under the current domestic subsistence rates, a qualifying journey lasting at least five hours can attract a meal allowance of up to £5, a journey lasting at least ten hours can qualify for up to £10, and a journey lasting at least fifteen hours and continuing beyond 8pm can qualify for up to £25. In certain circumstances, an additional £10 late-evening allowance can also apply.
These amounts should not be interpreted as free daily pocket money for company directors. There must be a qualifying business journey, the relevant subsistence cost must actually have been incurred, and the company needs to satisfy HMRC’s conditions, including the appropriate checking process.
In other words, owning a Limited Company does not mean that leaving the house with a laptop automatically earns you £25 for dinner.
Business trips abroad
International business travel introduces another layer of rules. HMRC publishes Overseas Scale Rates for employees travelling outside the UK, with different amounts depending on the country and, in many cases, the particular city.
There is therefore no universal UK rule saying that a director travelling abroad can simply claim £50, £75 or any other chosen amount for every day spent outside the country. A business trip to Vilnius, Paris or New York may be subject to different scale rates and conditions.
Depending on how the company handles expenses, qualifying actual costs may also be reimbursed where they are properly supported and satisfy HMRC requirements.
Flights, trains, taxis and hotels can all potentially qualify where they are genuinely required for business travel. The same applies to parking. A parking fine, however, is a rather different creature. Paying to park during a legitimate business journey can be an allowable expense; receiving a penalty because the car was left somewhere it should not have been does not magically become tax deductible because there was a client meeting afterwards.
HMRC has heard that one before.
Temporary workplaces and the 24-month rule
Another important area for Limited Company directors and employees is the concept of a temporary workplace. Travel to a temporary workplace can qualify as business travel where HMRC’s conditions are satisfied, but the definition is more specific than simply calling somewhere “temporary”.
This is where the well-known 24-month rule comes in. Broadly, where an employee attends a workplace to a significant extent – normally 40% or more of their working time – and the period of continuous work there lasts, or is expected to last, more than 24 months, that workplace will generally cease to qualify as temporary under this rule.
An important detail is that you do not necessarily wait until day one of month 25 before anything changes. If, for example, you originally expected an assignment to last 18 months but later discover that it will continue for 28 months, the tax treatment can change from the point at which the expectation changes.
This is particularly relevant to contractors and directors who spend long periods working at the same client site. Simply saying “it’s a temporary contract” does not automatically make every journey allowable for two years. HMRC looks at the actual working arrangements and what was reasonably expected at the relevant time.
Travel expenses are worth claiming – when they really are business expenses
Business travel is one of those expense categories where relatively small amounts can become a substantial figure over a full tax year. If you regularly visit clients, travel between sites, attend conferences, stay overnight for work or make genuine business trips abroad, failing to record those expenses can mean paying tax on profit that could legitimately have been reduced.
At the same time, trying to turn every journey into a business expense is not the answer either. A client visit and the daily commute to a permanent workplace are not the same thing. Sole Traders and Limited Company directors do not always follow identical rules, and mileage, subsistence, overseas travel and temporary workplaces each come with their own conditions.
The best approach is surprisingly unexciting: keep good records, understand why the journey qualifies and apply the correct HMRC rules. Tax rarely rewards creativity quite as much as accurate paperwork.
If you travel regularly for work and are unsure whether your mileage, meals, accommodation or other UK travel expenses can legitimately be claimed, Bilinscope Ltd, a professional UK accounting team, can review your circumstances and help make sure your business expenses are treated correctly under current HMRC rules.
Because one of the most expensive mistakes in business is not always claiming too much. Sometimes it is spending years not claiming perfectly legitimate expenses simply because nobody explained that you could.
