Which company for heating cost billing

hello I recently bought a house with 3 apartments I have no knowledge at all regarding ancillary costs etc until now I always had to pay a lot extra
now I also have to do the billing myself

now I wanted to ask you what experiences you have had with companies that do the billing?
which companies are there for something like this? I only know ista and A-Z heating cost billing
are there other companies if yes where can I find them?
what does such a company cost?
which is the best?
and which the cheapest?
I would appreciate your answers

Hi,

there are many companies for heating costs. Whether they include the operating costs depends on their offer. Are there now heat cost allocators on the heaters? Normally, these are tied to a company and you can’t just get out of the contract that easily. The costs for the billing of heating and hot water costs are usually also automatically passed on to the tenants. By the way, there are also administrations that only do the billing if you hand over all receipts to them. The easiest of all is an administrator who takes all problems off your hands and handles rent receipts, reminders, and repairs. What do they cost? Depends on the location. I guess between €12.00 and €20.00 net per residential unit per month. But all deductible via rent at the tax office.

The previous owner had a contract with ista Heizkostenverteiler are on the radiators but they are very old parts and they don’t have a contract with me yet, so I am asking about them and looking for other better or cheaper options
