Many of the Tenancies offered by Unipol are fully inclusive, this means the bills are included in your rent. It is your responsibility to check your tenancy to find out if you have household or utility bills to pay.
Tenants sharing a property usually have joint responsibility for the household bills. It is important you organise and agree this as soon as possible after moving in, it is very stressful to try and manage this without any agreements and Unipol cannot intervene in disagreements over payment amounts.
For further information please have a look through the Tenancy Support Guide in your own time.
