I checked this out as I have the same situation. My solicitor informed me that: 

"Providing they do not contribute to mortgage or anything structural to the property then they do not have a claim. You can however charge them for the bills and ask for contributions towards decorating, similar to what you would do in a rental property" 

The landlord/tenant model is a pretty good one you just don't have any rent payments.

The things a landlord should pay for are the ownership ones, keep them as your own.

The things a tenant would pay for are the living in a place costs, they can be shared.

I would keep most maintenance on the landlord side.
Bit of decoration could cross the line depending how extensive.

Mowing the lawn would not, laying a new lawn would

planting a specimen  tree : owner,  growing veg : shared.
