Does the Building Safety Act 2022 (BSA 2022) modify whether it is landlords or tenants who are responsible for paying the cost of remedial works to a building? If so, could this override the agreed contractual position under the lease? Where, for example, the lease was a full repairing lease, could the contractual obligations be effectively modified by BSA 2022, such that the landlords could have repairing obligations to meet at their cost?
