A resident is questioning a £5000 plus GST charge levied by their society's management company, FMS, for moving to a different flat within the same building. The resident argues no services were provided to justify the fee and seeks to understand if this charge is legitimate and legally challengeable, especially as FMS manages the society, not a separate relocation company. The response suggests clarifying the nature of the society's registration and the basis for these 'shifting charges' in the resident's agreement.
