If you are opposing your tenant's statutory right to a lease renewal you should exercise caution when relying solely on grounds (e), (f) or (g) of s30 of the Landlord and Tenant Act 1954 (being, respectively, (e) the chance to grant a letting of the whole (where the current tenancy was of part), (f) re-development requiring vacant possession and (g) occupation and use by the landlord). In these circumstances, your tenant will be automatically entitled to statutory compensation on quitting the property (calculated at the rateable value of the property but doubled if the tenant and any predecessor in business have been in occupation of the property for 14 years or more).
However, by also relying on one of the 'fault' grounds, such as (b) persistent non-payment of rent, then the tenant is only entitled to compensation if it goes all the way to trial and the judgment shows you were only successful on the grounds of (e), (f) or (g). Therefore it can pay to consider which of the other grounds you can also rely on. You might stop an automatic pay-out.
