A quick question I hope! I live in a mixed development and the method to calculate the fee for houses is set out in our deeds. It specifically states that the costs of external services only be used in this calculation however it transpires that non external costs e.g. light and heat, lift maintenance and other apartment specific costs are being included to calculate the fee. The agent says its not an issue as the fee is agreed at AGM. Are there any grounds to dispute the make up of the fee?
