Commercial landlord and tenant

Specialists in commercial landlord and tenant law, we provide expert knowledge and advice to negotiate and/or enforce a lease, such as extensions and renewals, forfeiture of commercial leases, service charge disputes, rent reviews, dilapidation disputes, lease assignments and recovery of rent arrears.

We recognise that a well-documented and drafted commercial landlord and tenant transaction will likely deliver our clients’ expectations. Equally, where litigation is needed, particularly in commercial tenancies, our specialist property litigation team can find solutions.

We provide businesses and individuals with a personal and genuine alternative to the traditional City law firm.
