New UK number plates are released twice a year, on 1 March and 1 September. For anyone buying a van, car, or other business vehicle, that twice-yearly change is worth understanding — not because the plate itself matters, but because of what it does to price, timing, and value.
How the plate change works
Each new plate uses a code tied to the year: the March release uses the first two digits of the year, and the September release uses the year plus 50. So a vehicle registered in March 2026 carries a “26” plate, and one registered from September 2026 carries a “76” plate. The system resets every six months, which is why demand for new vehicles tends to spike just before each changeover.
The case for buying around the change
Timing a purchase to land just after 1 March or 1 September can work in a business’s favour. Dealers are often keen to clear vehicles registered on the outgoing plate, which can mean sharper discounts on stock that’s barely been used. There’s also typically wider choice, since competition for popular models cools off once the rush has passed.
Sole trader example: A self-employed electrician buying a new van waits until early September, picks up a March-plated model at a reduced price, and puts the saving towards new equipment.
Limited company example: A small building firm timing a fleet refresh finds dealers more willing to negotiate on price and spec in the weeks after the plate change, when they’re not competing with a wave of plate-driven buyers.
The case for not chasing the plate at all
Many businesses do better by ignoring the plate cycle entirely and buying whenever it suits their operations, cash flow, or accounting year. A slightly older-looking plate rarely affects how a vehicle performs, and for vehicles that aren’t customer-facing, appearance matters far less than cost.
Sole trader example: A mobile dog groomer buys a used van mid-year when a good one comes up locally, rather than waiting for a plate change, since her clients never ask what year the van is registered.
Limited company example: A consultancy buys a pool car in June to align with its financial year end, prioritising the accounting benefit of when the purchase falls over any plate consideration.
Why the timing of purchase matters beyond the plate
Separately from the plate itself, when a vehicle is bought affects which accounting period it falls into, which in turn affects when capital allowances can be claimed. A business with a year end close to a prospective purchase date may want to weigh up buying just before or just after that date, based on cash flow and how the timing interacts with their wider accounts — not based on the plate.
The limited company vs sole trader difference
For a sole trader, a vehicle purchase sits within personal business accounts, and the timing decision usually comes down to cash flow and immediate need. For a limited company, the same purchase interacts with the company’s financial year and capital allowances, so timing can have a more direct effect on the company’s tax position. In both cases, the plate itself is rarely the right reason to buy — the underlying business timing is.
