The government must clarify that a non-consenting leaseholder who subsequently participates in a conversion will be required to contribute to the shared costs incurred by those who did previously participate in a collective enfranchisement. The government must design a mechanism for non-consenting leaseholders to contribute towards the shared costs of a 107 collective enfranchisement if they choose to join a commonhold at a later date. In response to this report, the government must set out its plans for such a mechanism, which must include a contribution towards the premium paid for buying the freehold of a building’s common parts and the legal and other professional costs incurred. (Recommendation, Paragraph 159)
