Each block, however similar, will have costs that can vary or have a different number of flats which may affect the basis of apportionment.
For example, one block may have more flats than another so the costs are spread amongst more properties; this makes the cost per property lower. Some services may vary between blocks because of size such as the area of grounds to be maintained or equipment or services provided and/or residents requests for additional services. We will never discuss another tenants service charge with you.
