“Revaluation helps to redistribute the amount paid in business rates across sectors and regions,” says the Valuation Office Agency. From 1 April 2026, England’s new transitional relief will cap how quickly bills can rise, with a higher small‑property threshold in Greater London than the rest of the country - a detail that matters for Northern high streets as valuations reset. (gov.uk)

The scheme runs for three years, from 1 April 2026 to 31 March 2029. For the smallest properties, annual increases are capped at 5 percent in 2026–27, 10 percent plus inflation in 2027–28, and 25 percent plus inflation in 2028–29. (gov.uk)

For medium‑sized premises the caps are 15 percent, then 25 percent plus inflation, then 40 percent plus inflation; for large sites they are 30 percent, then 25 percent plus inflation in each of the next two years. London keeps a higher ‘small’ threshold at £28,000 rateable value, compared with £20,000 elsewhere. (gov.uk)

These limits are applied year‑on‑year and before other reliefs or local supplements are taken off the bill. That means the cap is set first, then mandatory reliefs such as small business relief are applied, and any local top‑ups come after. (local.gov.uk)

One London‑specific wrinkle remains. In the City of London - designated in law as a special authority - the Common Council can set its own premiums alongside national multipliers. Where that local multiplier differs, bills are adjusted under the new regulations so City ratepayers aren’t penalised by the local setting. In practice, this mainly affects firms inside the Square Mile. (cityoflondon.gov.uk)

To help fund the scheme, there will be a temporary 1p supplement on the relevant tax rate in 2026–27 for properties that do not receive transitional relief or the new Supporting Small Business scheme. Councils including Manchester have already flagged this in their guidance to firms planning next year’s cash flow. (local.gov.uk)

For businesses losing some or all Small Business Rate Relief because of the revaluation, increases in 2026–27 will be capped at the higher of £800 or the standard percentage cap for their band. This cushions micro‑firms that fall out of relief as values change. (gov.uk)

Here’s what that looks like on the ground. Take two shops each with a £22,000 rateable value. In Camden, the London threshold means the shop sits in the ‘small’ band, so the bill can rise by no more than 5 percent in 2026–27. In Salford, the same value falls into the medium band, so the rise can be up to 15 percent in the first year. (gov.uk)

For a Teesside manufacturer with a £120,000 rateable value, the first‑year rise is capped at 30 percent, then 25 percent plus inflation in each of the next two years. That doesn’t remove the increase but smooths the shock as valuations based on the 2024 market feed through to bills from April. (gov.uk)

Northern councils and the VOA are urging firms to look up their future valuations now and check the property details the VOA holds. You can sign in to see how your valuation was worked out, compare with similar properties and fix any factual errors - with current‑list challenges due by 31 March 2026. (gov.uk)

Multipliers also change next year. Published figures show new, permanently lower multipliers for eligible retail, hospitality and leisure premises, alongside a 50.8p high‑value rate for properties with a rateable value of £500,000 and above. The City of London will confirm its own premium in early March. (manchester.gov.uk)

If you receive a transitional certificate, your council will use that value in the bill calculation; if you disagree, you should contact the Valuation Office Agency in the first instance. For firms across the North, the immediate to‑do list is simple: check your valuation, model a 5, 15 or 30 percent first‑year rise depending on your band, and talk to your council early if cash flow will be tight.
