A consultation process under which leaseholders must be consulted if any works in the building are anticipated which are expected to cost more than £250 (including VAT) for any one Leaseholder in the property.  If consultation is not undertaken, the maximum that the landlord may legally be able to recover is £250 per Leaseholder. Qualifying long-term agreements, that is agreements of more than 12 months in duration, are also covered under the Section 20 consultation process.  This is a complex area of property legislation and specialist advice should be sought if necessary.
