Fire risk assessment - holiday lets

I am in the process of buying my first ever holiday let.  As we know the legislation is different to buy-to-lets along with the tax treatment.  The advantage for holiday lets is that the business for furnished holiday lettings are assessed as a trade not an investment which allows me to offset a far greater number of expenses.

However, as ever there is more legislation to contend with including the requirement to carry out a fire risk assessment for paying guests.

How do I get 12 months rent up front?
