Reclaiming training costs

“Q: Can I reclaim the cost of training against my tax?”

A great question, and the answer is… “quite possibly – but it depends”.

If you already run a business, the cost of a training course could well qualify for tax relief. UK Detailing Academy is a dedicated training institute with SIC code 85590 (Other education), which identifies us as somewhere professionals go to receive training, one of the things HMRC looks for when checking returns and claims – one of the benefits of being a genuine training academy, and not just a offering training on the side.

In practice, that means if your end-of-year accounts showed, say, a £10k profit and you’d spent £2k on training to sharpen the skills you use in the business, you could deduct that cost and pay tax on £8k of profit instead. The government effectively chips in towards your training by not taxing you on the amount you paid for it, like any other business expense.

The rules changed in your favour in 2024

This used to be far more restrictive. For years, HMRC only allowed a deduction where the training updated a skill you already had – a refresher. Anything that taught you a genuinely new skill was treated as “capital” expenditure and blocked.

That changed in 2024. HMRC now accept that training is an allowable revenue cost as long as it’s “wholly and exclusively for the purposes, or ancillary purposes, of the trade” – which includes learning new skills within your existing business, keeping pace with new techniques and technology, and even ancillary skills like book-keeping or digital marketing that help you run the place. The full detail sits in HMRC’s Business Income Manual at BIM35660.

The one big line that remains: training to start a brand-new, unrelated trade is still treated as capital, and isn’t directly deductible. The test is whether the training serves the business you’re already running. How long your have been running shouldn’t come into it though… as long as you can prove trading, and this is where the definition is important. Trading means real commercial activity: actual paid work, customers, invoices. A company that exists on paper but hasn’t genuinely started its trade is dormant, not trading – so incorporation alone doesn’t satisfy the test.

How you report it depends on your set-up. If you’re self-employed, HMRC looks at your existing trade – provided the training relates to it, the cost is normally deductible and goes on your self-assessment return. For a limited company, training for directors and employees that’s relevant to the trade is usually an allowable company expense – though providing training for employees can bring certain tax, National Insurance and reporting obligations, so it’s worth knowing where you stand.

So what does that look like for a detailer?

An allowable course would be something like a wet sanding or ceramic coating course taken by someone already running a detailing business – a new skill, but squarely within the trade you already operate.

A course that likely wouldn’t qualify is one that sets you up in a genuinely different line of work – retraining as, say, a driving instructor – or a course taken before you’ve started trading at all, to get the business off the ground (see below).

There’s a grey area worth flagging: adding a closely-related service – PDR (paint dent removal), or leather repair for instance – to an existing detailing business is much more likely to qualify now than it was under the old rules, because you’re expanding an existing trade rather than starting a separate one. But that’s exactly the sort of judgement call where your accountant earns their fee.

If a course doesn’t qualify for straightforward training relief, it’s still worth a conversation with your accountant – the line between developing your existing trade (allowable) and starting a new one (not) is genuinely grey in places, and your circumstances can make the difference. What no one can do is turn a genuinely non-deductible course into a deductible one through clever paperwork, so treat anything promising that with caution. And if you do have to bear the full cost, it’s still an investment in you – and one you’ll very likely earn back many times over.

The catch if you haven’t started yet

Here’s the part that catches people out. There’s a general relief that lets you claim certain costs incurred in the seven years before you start trading, as if they happened on your first day – but HMRC generally doesn’t extend that to training taken to get a new business off the ground. Because you weren’t trading at the time, start-up training tends to fail the “wholly and exclusively for the trade you’re carrying on” test and is treated as capital. So if you’re training to enter the industry rather than to develop an existing detailing business, don’t assume it’s deductible – check first.

The bottom line

As always, the best move is a quick word with your accountant or tax adviser, who can tell you fast whether a cost is allowable. If it is – congratulations, the government just helped pay for your training by not taking the tax on it.

If it doesn’t qualify as straightforward training relief, there may be other mechanisms they can point you to, such as capital allowances or a director’s loan arrangement – but that’s why they went to accountancy school instead of detailing school. And if you simply have to bear the full cost, it’s still an investment in you, and one you’ll very likely earn back many times over in the medium term.
