Can subbies drive your vehicles?

by | Jan 21, 2023

There are many myths surrounding the use of subcontractors in the construction industry. One of the common myths we hear is that subcontractors can’t drive your company cars or vans. This isn’t true.

Your subcontractors can drive your company vehicles. However, if HMRC suspects you are disguising employees as subbies, they might use the fact that subbies are driving your vehicles to strengthen their case against you. You can avoid misunderstandings with a bespoke subcontractor agreement.

If your contractor agreement explains the use of company cars and vans by subbies, you can shut down HMRC’s questions before they open a full enquiry into employment status.

How to handle HMRC queries

It’s unlikely that HMRC will be hanging around your work sites checking whether subbies are driving your vans.

An enquiry usually comes about when HMRC are looking into a tax issue.

For example, one of our clients was in discussions with HMRC about a VAT repayment when HMRC decided to casually drop in the following query:

“Please explain why (name) and (name) are driving company vehicles bought by the company and using company fuel cards, considering that they are not employees of the company.”  

For many construction firms (and their accountants), this kind of question would cause panic. After all, we’ve all heard the horror stories of contractors being forced to pay hundreds of thousands in back taxes and fines because HMRC suddenly decided to reclassify their subbies as employees.

Our client, however, didn’t panic because he knew we had his back.

We know exactly how to handle this type of query, and it’s not by sending responses along the lines of:

“We like to promote a good and clean image for the business, that’s why the subbies drive our vans,”


“It’s impossible to get the workforce if we don’t provide vans because all our competitors do it.”

Because while those statements might be true, they aren’t going to cut it with HMRC. HMRC doesn’t give a toss about your company image or your struggle to source reliable subbies.

What HMRC cares about is whether you are disguising employees as subbies to get out of putting them on PAYE and being liable for tax, NI, pension contributions, and holiday or sick pay.

So how did we explain the van thing to HMRC and ensure it didn’t turn into a full-blown enquiry into employment status?

Our response was simple: “Any use of company vehicles is reflected within the rate paid to the subcontractor.”

And do you know how we made it 100% bulletproof? It was reflected in the contract our client had with his subcontractors.

What to consider when letting subbies use your vehicles

It’s not uncommon for subbies to operate vehicles that are owned and branded by the main contractor. As long as you have an adequate insurance policy and are aware of the risks, it’s perfectly fine.

However, you will need to consider how it could look to HMRC. Why do you need a fleet of vans if you don’t have any employees to drive them? Why is a subcontractor driving your company vehicle instead of their own?

On their own, these things don’t prove anything. But when combined with other factors, they can be used to form a case against you.

If your subbies are genuinely self-employed, they are a business in their own right. And if they are a business in their own right, why are they using your vehicles and equipment, claiming fuel expenses and other expenses, and wearing your uniform when carrying out work?

You can see why these things added together might make it look as though your subbies should actually be employees. And that’s why having a contract is so important.

Contractual agreements

If your relationship is one of employer and employee, you need an employment contract – a contract of services. If your relationship is one of contractor and self-employed subcontractor, you should have a contract for services.

And that contract should outline the true working relationship you have with your subbies – in other words, it should match up with what happens in real life.

So if your subbies drive your vans, make sure this is noted in your contract. Don’t leave any room for doubt.

And be clear on the rules for use. You don’t want subbies using your vehicles for private use as you’ll be responsible for the upkeep.

Other implications of subbies using your vans

Now you know it’s ok for subbies to drive your vans, you might be tempted to upgrade your fleet. But before you rush off to buy new vans for everyone, there are other considerations

Aside from the costs involved in running a fleet, there may also be tax implications for you to consider. It’s a good idea to get advice from your accountant before investing in any new vehicle.

You should also make sure your subbies are responsible drivers – the last thing you want is a hefty bill for property damage. Don’t assume they will look after your vehicle.

What you need to know about HMRC

Despite what it might feel like, HMRC hasn’t got it in for construction firms. HMRC just want to ensure they are paid every penny they are owed in taxes. And that’s understandable really – why should some people do things by the book while others cheat the system?

Unfortunately, their enthusiasm for uncovering dodgy dealings often results in legitimate businesses getting caught in the crossfire.

But it’s not like there’s a squad of HMRC employees wandering around construction sites looking for subcontractors wearing your uniforms.

Most enquiries into employment status come off the back of something else – an enquiry into VAT, CIS or corporation tax, for example. This is exactly what happened with our client – an issue over a VAT repayment led to HMRC asking why their subbies were driving company vans.

And that’s how it starts.

Luckily, we were able to explain this and prevent any further questions. But if you don’t have a satisfactory response and your contracts aren’t watertight, then you could end up with an enquiry on your hands.

And even if there’s nothing for HMRC to find, you don’t really want the extra hassle of dealing with their questions.

The truth behind all the myths

It’s not surprising that so many construction companies are cautious about how they work with subbies, what with all the misinformation that gets spread around the industry.

You’ve got the hearsay – “I heard about this firm that got fined £500k because they had subbies wearing their uniforms” (probably never happened)

Then you’ve got the misinterpretations – “I checked on CEST, and my subbies are outside IR35” (IR35 is irrelevant if your subbies are sole traders and the CEST tool is shit anyway).

And then there are the blatant lies – “If you want to work with subbies long-term, you have to use a payroll company” (complete bollocks).

You can work with subbies long-term and keep HMRC happy without using a payroll company. What’s more, your subbies can drive your vans, wear your uniform and use your tools. You can pay for their fuel, their training and even their lunch (if you’re feeling particularly generous).


Full transparency. If your true working relationship is documented clearly and concisely in your contracts, you aren’t leaving anything open to misinterpretation.

If you can demonstrate a legitimate reason for why you work the way you do, then HMRC will usually lose interest pretty quickly.

How do you protect yourself?

The easiest way to protect yourself is to work with us. We know you’ll probably think we’re biased, so let us lay out the other options so you can see why we think our way is best.

Put your subbies on PAYE

If you treat them like employees, they act like employees, and they are employees in all but name, then why not stick them on the payroll? Employing your best subcontractors certainly has some benefits. However, if that’s not an option, there’s always option two…

Use a payroll company

This is one of the most common solutions. Let payroll companies worry about subcontractor contracts and HMRC enquiries. And in theory, it’s great. Until you realise that those contracts the payroll companies use are designed to protect them, not you, and their requirement for you to pay CIS and VAT on every invoice can have a huge impact on your cash flow.

DIY contracts

We’d recommend you avoid off-the-shelf templates, but it is possible to create your own bespoke subcontractor agreements – our free book even teaches you how. This gives you the protection you need – as long as you get it right and keep it up to date. But if you haven’t got the time, legal knowledge or inclination to sit and create contracts, you’ll probably find option four more appealing…

Work with HardHats

We create bespoke watertight contracts for you. And we get all your subbies to sign them digitally using our fancy software. Plus, we protect all our contracts with an insurance-backed guarantee. We handle any HMRC enquiries, and should HMRC ever reclassify your subbies (unlikely when you work with us), we’ll cover any associated costs.

So there you have all the options – you just need to decide which is right for you.

Of course, you could do nothing. Carry on as you are. Just make sure you’ve got some great responses lined up in case HMRC ever do want to know why you’re working with your subbies the way you are.

But if you’d rather not run that risk and options one, two and three don’t work for you, get in touch.

You might not even need our help!

But if you use labour-only subcontractors long-term and want to continue doing so, let’s have a chat. If you are at risk, we’ll take that risk off your hands.
