Anything similar to R&D Tax Relief for small business?

Managed to get my company back a lot of money recently from HMRC using R&D Tax Relief.

Is there anything similar to this or EIS that allows your company any sort of Tax Relief or lump sum paid back from HMRC?

Hugely appreciated if anyone can help out. I've had a quick look around but have only found stuff on R&D and EIS so far.

many thanks,
