Lease variations

Lease variations

While this Overview primarily concerns commercial property matters, it also touches on residential considerations.

Parties often wish to renegotiate the terms of an existing lease. Following completion of a lease, landlords and tenants are free to negotiate a variation to the lease terms (although generally the other party is under no obligation to negotiate or agree any variation).

The parties will usually enter into a deed of variation to expressly record any agreed variation to the original lease. If the change to lease terms is a personal or temporary concession, the parties may agree to enter into a side letter instead—see Practice Note: Side letters to leases and Precedent: Side letter modifying lease terms.

Key areas of risk relating to lease variations include:

•
inadvertent surrender and regrant (by operation of law)
•
release of guarantors (or former tenants that remain bound by tenant covenants) and other issues relating to guarantors
•
failure to obtain necessary third-party consents (eg superior landlord, mortgagee)
•
unintended consequences, including in relation to superior leases, underleases or tax, and
•
failure to comply with registration requirements

Occupiers’ liability and the threshold test for duty of care (Lillystone v Bradgate)

PI & Clinical Negligence analysis: Upon appeal, the High Court found that a claimant casual footballer paying to play a ‘knockabout’ game at school premises where there were no arrangements in place to retrieve a ball kicked out of play into another part of the defendant’s sports facilities (adjacent sports playing fields) caused his own injury when he climbed a 2.1m gate and severely lacerated his hand. The claimant was a trespasser while climbing the gate between two adjacent parts of the premises where he was not a trespasser. The defendant’s duty of care did not extend to providing any system or facilities to aid ball retrievable, despite the trial judge’s findings that doing nothing and waiting was ‘not what football players would do’. The threshold test imposing a duty of care was not met because the claimant decided to climb the locked gate to gain access to adjacent playing fields. What amounts to ‘reasonable’ safety of visitors under section 2(2) and (5) of the Occupiers’ Liability Act 1957 (OLA 1957) appears to fall firmly within the characteristics equating to a definition of ‘reasonable’ amounting to ‘adequate’, rather than equating to the dictionary definition of reasonable ‘based on or using good judgment and therefore fair and practical’. On the facts and circumstances of this case the sports premises were safe, despite there being no facility for ball retrieval. The danger to the claimant only arose because the claimant decided to take a risk to climb a gate that was an obvious danger. Written by Abigail Holt, barrister at Garden Court Chambers.

BPF responds to GLA and MHCLG consultations on London housebuilding measures

The British Property Federation (BPF) has published its responses to consultations by the Greater London Authority (GLA) and the Ministry of Housing, Communities and Local Government (MHCLG) on measures to support housebuilding in London. BPF welcomes the proposals as a step in the right direction to improve scheme viability and accelerate housing delivery in the capital. However, it says the measures do not go far enough to address London’s structural viability challenges. BPF highlights concerns including the short, time-limited nature of the proposed relief, the exclusion of some housing models, barriers facing small and medium-sized developers, and the limited scale of Community Infrastructure Levy (CIL) relief.
