Your rights to inspect the property are a separate issue to the delay in rental payments and you should check the tenancy agreement in this regard.
Under the Housing Act 1988 Section 8 Ground 11 a Landlord is entitled to take possession of the property if the Tenant has persistently delayed paying rent when it has become lawfully due. You should serve upon the Tenant a Notice to terminate giving two weeks' notice. You should serve the notice in the required form and you can download the prescribed form online from www.lawdepot.com
