heating hot water bill

I moved into a new build property in 2008. I am a housing association tenant and the apartments are a mixed development. 140 are private and 148 are part buy and social housing. We have just received our bill for water and heating after waiting 3 years as they did not know what way to bill us.

The private are billed direct from the management company and are charged 1p per day standing charge on top of the water heating that they use.
The ha tenants (including part buy) bill is sent by the management company to the ha who then pass the bill on to another company to issue bills on behalf of leaseholders and residents. We are being charged £35 +vat=11.5p per day for first year only for this account to be set up.
Annual billing and collection charges of £56.34 +vat=18.52p per day total 30.02p per day admin charge. We also then have standing charges of 22.41p per day for heating and 28.44p per day for water inc vat. This is for management company to collate readings and issue billing and invoices to h.a.

This adds up to 80p per day standing charges without using heating and hot water. Are the management company allowed to bill us these ridiculous amounts. The housing association then add on more for their admin charges whilst the private flats only pay for what they use plus 1p per day on top.

Myself and my neighbours were not told about this when we moved in or bought the apartments. I was told that I would be billed for what I used.
