Generally, the tenant will pay for any alterations they wish to make unless the alterations are essential (eg if they must be made to ensure that the property is fit for human habitation or to repair the property). If the alterations are essential, the landlord must usually cover the cost of the alterations.
This Landlord Consent to Alterations Letter also requires that the tenant pays any reasonable expenses incurred by the landlord or the landlord’s advisers (eg lawyers) or surveyors in connection with the proposed alterations. For example:
costs associated with having a surveyor check the alteration plans and the work itself
any general administration charges
