Glossary
Bear in mind that most standard leases will prohibit alterations so if you think you may want to erect shop displays, install partition walls, install new heating systems or flues etc then you will need to agree this with the landlord in advance. If you are negotiating a longer term lease and you want the freedom to carry out more significant alterations then try and agree this with the landlord in advance.
Negotiation tip: if the landlord is unwilling to agree to you having the freedom to carry out major works suggest that the lease includes rights for the landlord to review the plans and specifications and a right to veto them if your proposals are unreasonable.
