Most business owners we speak to in February already know something needs sorting. One of the company cars is up in May. A van’s been quietly racking up miles it shouldn’t. A driver muttered something about wanting an electric next time. None of it is urgent yet, which is exactly why it’s about to become urgent.
The April tax year doesn’t just matter to your accountant. It moves Benefit in Kind rates, it shifts what your drivers actually take home, and it sends the leasing market into a six-week scramble that’s entirely avoidable if you’ve planned for it.
This is a guide to thinking about your fleet in tax-year terms, so any car or van due for renewal in the coming twelve months gets handled in good time, with the tax position working for you. Half an hour now saves a frantic week in April. We promise.
Why April is a hinge point, not just a deadline
The UK tax year runs from 6 April to 5 April. For company vehicles, that date carries three things at once.
First, Benefit in Kind rates can change. HMRC publishes BIK percentages by tax year, and they typically step up for petrol, diesel and hybrid cars. Electric vehicles have enjoyed unusually low rates, but those are scheduled to rise gradually too. Always verify the current figure against HMRC or your accountant before making a decision, because the rate that applies is the one in force when the contract starts.
Second, manufacturers work in quarterly cycles. January to March is often when the best stock deals appear, before factories pivot to new model-year production. Wait until April, and the menu shrinks.
Third, and this is the bit most people miss, every other business in the country is having the same thought you are. Lead times stretch. Popular specifications go on back order. The phone lines at every broker get busier. Calm planning in February sits in a very different market to panicked ordering in late March.
The four questions worth answering before you do anything
Before you look at a single vehicle, sit down for half an hour and answer these for every car and van on your fleet. It’s the same conversation we’d walk through with you, but a first pass on your own is genuinely useful.
When does each current contract end? List the vehicle, the end date, the driver, and the contracted mileage. Anything ending between April and December should be on your radar now.
Is anyone close to their mileage limit? Excess mileage charges at the end of a contract are one of the most common nasty surprises in leasing. Spotting it early gives you options. Letting it run does not.
Are any drivers due a change anyway? Promotions, new starters, someone moving from office-based to on the road. The vehicle that fitted three years ago might be wrong for the next three.
What does the BIK look like for each driver? A higher-rate taxpayer in a diesel saloon and the same person in an electric equivalent can be hundreds of pounds a month apart in take-home pay. That’s not a small detail. That’s the whole conversation.
Once you have that picture on one page, you’re already ahead of most businesses your size.
Renew early, renew on time, or wait
Most vehicles fall into one of a handful of patterns. Here’s a working framework, not a rigid rulebook.
| Your situation | What usually makes sense | Why |
|---|---|---|
| Contract ends April to June, driver happy with vehicle type | Renew early in February or March | Lock in current BIK, beat the spring rush, secure stock before Q1 closes |
| Contract ends July to September, driver wants to switch to EV | Plan now, order March to April | Lead times on popular EVs run long. Early orders protect against price moves |
| Contract ends October to December, driver position unclear | Diary a summer review | No need to rush. Use the time to assess driver needs and watch new launches |
| Driver heading for excess mileage on current contract | Talk to us about restructuring | A mid-term adjustment is often cheaper than the end-of-contract bill |
| Driver leaving the business | Don’t renew, look at short-term cover | A short-term car or van lease bridges the gap without locking you in |
| Contract just renewed, nothing wrong, no driver changes | Do nothing, diary the next check | Not every fleet needs constant attention. Knowing when to leave it alone is part of the job |
The right answer for your business depends on your cash flow, your drivers, and where the wider market is at the time you decide. That last bit is where having someone in your corner pays off, because the market changes every quarter.
The EV question, honestly
Electric vehicles have been the standout tax-efficient option for company car drivers for several years now. The Benefit in Kind rate on a fully electric car has been very low compared with petrol or diesel, which has made an EV substantially cheaper as a perk for higher-rate taxpayers. For some of our clients, the BIK saving alone has more than covered the difference in monthly rental.
That advantage isn’t disappearing, but it is narrowing. EV BIK rates are scheduled to rise in small increments.
What this means in practice is worth being clear about.
If a driver is moving from diesel to electric, doing it sooner rather than later locks in the lower BIK for the duration of the lease. Three or four years of that rate is a meaningful saving.
If a driver is already in an EV with a contract ending soon, renewing into another EV almost always still makes excellent sense. The gap between EV and petrol or diesel BIK isn’t what it was, but it’s still substantial.
If you’ve held off on EVs because of charging worries, the picture is genuinely different to even three years ago. Public charging is denser, range is better, and home charging is well understood. Our pages on real-world charging and range and what an EV will actually save you are worth a read if you want the unvarnished version.
The honest summary is that EVs still suit most company car drivers very well. The obvious-win margin is just smaller than it was, which means picking the right EV for the right driver matters more than ever. That’s the kind of conversation we’d rather have with you over a phone call than via an online configurator.
The five timing mistakes we see most often
After years of doing this, certain mistakes come up again and again. None of them are silly. They’re just what happens when leasing isn’t your day job.
Leaving it until the contract end month. By then, lead times on the popular specifications can be three to six months. You end up with a vehicle you didn’t really want, a short-term hire while you wait, or a panicked extension at a worse rate.
Renewing the same vehicle on autopilot. Drivers’ lives change. The estate that suited a young family three years ago may not be the right fit now. A ten-minute conversation often surfaces a better option.
Ignoring mileage drift. Contracted mileage that made sense when the contract started may be wildly wrong for how the car is being used now. Restructuring early costs far less than excess mileage at the end.
Stacking every renewal into the same month. If three vehicles all come due in April, every April becomes a fire drill. Where the numbers allow, staggering renewals across the year takes the pressure off permanently.
Choosing on monthly cost alone. A cheaper headline rental on a vehicle with a punishing BIK rate can leave a higher-rate-tax driver hundreds of pounds a year worse off than a marginally pricier car with sensible tax treatment. The full picture is what matters, and the full picture is what we’re here for.
Your February to April plan
If you take nothing else from this post, take this. Pencil it into the diary now.
February. Pull together the list. Every vehicle, every end date, every driver, every contracted mileage. Flag anything ending April to September. Book a half-hour call with us to look through it together.
Early March. Decisions made on anything ending April to June. Orders placed where lead times demand it. Drivers briefed on what’s coming so nobody’s caught out.
Late March. Quick review of July to September contracts, especially any EV switches where lead times stretch. Confirm the new tax year BIK position with your accountant.
April onwards. Settle into the new tax year without anything on fire. Diary a midsummer check-in for the back half of the year.
It really is that straightforward, but only if you start in February.
Where we fit in
We work with a deliberately small number of businesses, typically running anywhere from one to twenty vehicles where the cars and vans are a perk for the team rather than a full commercial fleet. That focus is the whole point. We get to know your business, your drivers, and your tax position, so when February comes around we already know which contracts are ending, who’s likely to push past their mileage, and which drivers would benefit from switching to electric.
You won’t get a quote and a chase email. You’ll get a conversation with someone who remembers your last renewal, your driver’s preferences, and the conversation you had about the van that’s always full of tools. That continuity is the thing comparison sites cannot give you, and it’s the thing that turns leasing from a recurring headache into something you don’t really have to think about between renewals.
If you’d like the broader picture, our business car leasing page covers how we work, and our electric car leasing page goes deeper on the EV side.
A calm February call beats a frantic April every time
If any of your vehicles are due for renewal in the next twelve months, the simplest next step is a half-hour conversation. Bring the list, even if it’s scribbled on the back of an envelope, and we’ll walk through it with you. No quote pressure, no upsell, just a clear view of what’s worth doing now and what can sensibly wait.
If you’d like to talk it through with someone who’ll actually get to know your business and your drivers, we’re easy to reach. Have a look at who we are and what our clients say, and when you’re ready, drop us a line.
