Rented: Legal question

[JumboBeef]

Hello All,

I am in a rented house (England), moved in about three months ago. The property is owned by a small development company.

Yesterday I received a form from them stating:

In order to comply with illegal immigrant status, health and safety regulations, tenants and landlords act 1954 and money laundering regulations, we would be pleased if you complete the below and return to us.

The form asks for my:

First name
Surname
Date of birth
NI number
Mobile number
Email address
Gas supplier
Electricity supplier
Water supplier
Gas meter ref
Electricity meter number
Water meter number
Local authority
Council tax ref no.

I have rented before and have never been asked these questions (of course they already know certain info, my name and mobile number, and the meters were fitted by themselves...!) Do they have a genuine reason to ask for this information?

Thanks.

Thanks for the replies. I'm not on benifits and pay all the rent myself.
