Guarantor scheme vs Guarantor

Guarantor scheme vs Guarantor

As a LL are there pitfalls with accepting Guarantor schemes as opposed to private individual Guarantors? Or are they treated identically.

Anyone with experience claiming from Guarantor Schemes?

For reference, two such paid Guarantor Schemes that Ts can use if they don’t have a U.K. based Guarantor are: Housing hand and Rent Guarantor

Thanks
