Regardless of a lessor`s right to cover costs under a rental agreement, if the legal consultation requirements are not properly met, whether they concern QLTAs or qualifying works (whose legal ceiling is £250), the lessor may not be able to recover from its tenants all its repair costs, maintenance and management of a building. Tenants should consider the pros and cons of long-term contracts depending on the circumstances. How long they are, what they are for, how prices will go up and similar questions. If tenants have any doubts, they must communicate them within 30 days from the date of the first of the two notices referred to in section 20 in a written “remark” to a landlord. . . .
