To claim under ERIS,enhanced youResearch alsoand Development intensive support, you have to meet the following intensity condition.
Intensity condition
A company meets the intensity condition if:
- it’s claiming for an accounting period beginning on or after 1 April 2024
- its relevant R&D expenditure is at least 30% of its total expenditure (including that of any connected companies — read the Corporate Intangibles Research and Development Manual for information)
Generally, you will need to meet the condition for the period for which the claim is made.
There is also a grace period, which means you can claim if both of the following apply:
- you met the condition in your last 12-month accounting period
- you
andmade a valid claim to SME relief or ERIS in that period on expenditure incurred on or after 1 April 2023
Profit-making and non-R&D intensive SMEs with qualifying R&D expenditure can claim relief under the merged scheme instead.

Intensity condition
A company meets the intensity condition, for an accounting period beginning on or after 1 April 2024, if its relevant R&D expenditure (plus that of any connected companies) is at least 30% of its total relevant expenditure (plus that of any connected companies).
