The Three-Year Window

What actually changed to business rates in April 2026 — and why it matters if a second unit's been on your mind.

The economic headlines haven't been kind to small business lately. Growth confidence in England has dropped to its lowest point in over a decade, and fewer new businesses are being registered than at any point in the last ten years. If you're feeling that in your own trading, you're not imagining it.

But buried in a much duller headline — business rates — is a genuine bit of good news for anyone thinking about growing from one unit, stall or shop into two.

What's changed

Small Business Rate Relief (SBRR) is the discount that keeps your rates bill manageable if you run a modest single-site operation. The catch has always been what happens when you take on a second property — a second unit, a second pitch, a bigger workshop alongside your existing one. Until this year, you kept your relief on the first property for just one year after adding the second. After that it dropped away, sometimes catching people out with a much bigger bill than they'd planned for.

From April 2026, that grace period has been extended to three years.

Why it matters

Growing a business rarely pays for itself in month one. A second unit usually needs a run-up — new stock, new staff, new customers who don't know you're there yet — before it earns its keep. The old one-year rule meant you could find yourself paying full rates on your original, already-established property just as the new one was starting to find its feet. That's a rough time for a rates bill to jump.

"Three years gives you room to actually get the second property established before the relief tapers off — and timing is often the difference between a second unit that works and one that quietly drains the first."

Worth checking before you assume it applies

This only protects the relief on your original property — the new one is assessed on its own rateable value from day one, it doesn't inherit anything. The wider rates system changed too, with new multipliers from April 2026 depending on your property's size and whether it counts as retail, hospitality or leisure; if your bill has moved and you're not sure why, that's usually the reason, and it's worth a call to your local billing authority to have it explained in plain terms.

Councils vary in how they apply the detail, so if you're already partway through adding a second property, don't assume the three years applies automatically — ask. None of this is tax advice, and rules like this get tweaked. Treat this as a prompt to check your own position, not a substitute for checking it.

From the register — resource

The early decisions around growing a business — when to take on a second unit, how to price the run-up before it earns its keep — are the ones the Starter Kit walks through.

Two extra years is more room to grow into than most rules ever give you.
