We're happy to help you out. Answer in short is yes you could be liable if you do not set your 'business' up correctly from the start. When opting to Let your property, you are starting your own business and therefore before you even open the doors, you are required by law to be compliant to all Health and Satety Regulations and carry the correct certification for habitation. high majority of homeowners do not do this as they do not advertise their properties openly and prefer to run the risk. However, apart from slipping, there are a multitude of other 'risks' you do need to cover, such as regular Gas or Electric Compliance checks. All electrical Goods will need to be checked and passed fit for use, currently it is every two years but that is dependent on usage.
Also, they are coming down very heavily on properties with 'Solariums'. As per all Hotels and accommodation across Europe, any balcony attached to any property has to comply to European Height Standards for H&S reasons, you could imagine the scenario of a family with children who can manage to climb over the wall of the solariums....!!!! If you are only thinking of guests and slippage due to tiles, most clients 'should' have their own Insurance Policy prior to Letting, cannot always be guaranteed though ! As part of the Letting, I would suggest you get Legal advice and a proper Contract drawn up that covers such Liabilities
Hope this helps, if you need any more assistance please feel free to ask
