“Whether a purported variation of a lease takes effect as a surrender and re-grant depends on the nature of the variation. If the variation cannot be effected without the grant of a new lease, then it will take effect as a surrender and re-grant.

However, in the absence of an increase in the premises demised or the length of the term, either of which will change the legal estate and work surrendered and re-grant, there will usually be no surrender.”
