You might be able to get business growth accelerator relief if:
Your premises is a new build property
You have to expand or make improvements to your property
Valid for new builds entered onto valuation roll from 1/4/18 onwards or expansion/improvements resulted in a Rateable Value increase from 1/4/18 onwards
From 1/4/21, relief may also be available where there has been an increase in rateable value following a property improvement and a change of use.
New build premises
Relief for new build properties is restricted dependant on when the property was entered onto the Valuation Roll. If the property was entered onto the Roll more than 12 months ago up relief can be applied until 31/03/25 or 12 months from the occupation date whichever is sooner. If the property was entered into the Roll within the last 12 months, relief can be applied for up to 4 years from the effective entry date while it remains unoccupied or 12 months from the date occupied whichever is sooner.
Business rates also don't have to be paid on new builds until they're occupied. New tenants will then qualify for business growth accelerator relief for 12 months.
Expanding or making improvements to your premises
If you have expanded or made improvements to your property the business rates you're charged won't change for 12 months. They will continue to be based on your old rateable value for this period of time.
