What control do I have over service charges?
It’s important to get the right terms in the lease in the first place. It would be useful to consult the RICS Code of Practice on Service Charges in Commercial Property which contains useful guidance material. Information about the Code, and details of how to download a copy, are available at » Service Charge Code
If you are unhappy about the provision of services for which you are charged, you may be able to refer the issue to the Courts under the Supply of Goods and Services Act 1982 or as a simple matter of breach of contract.
Seek professional advice before doing so.
