Please Help me on this by giving your advice?

I live in England in a rented property with my husband. We have been renting the property for the last 2 months for a contract period of 3 months with an option to continue every month with a one month notice. The property we live in is an annex attached to the landlady's house which has a seperate entrance. We were provided a cooker on request which means there was no cooker in this property before because the kitchen has a room on top of our kitchen and it is not allowed to do so. Instead the previous tenants have been sharing their kitchen. But when we requested for a cooker we were provided with an electric two hobs cooker since there are boys in that house and i did not want to use their kitchen. Now the landlady suddenly comes and says she wants to terminate the contract after 3 months and if we want to extend it she would not provide us with the cooker instead we would have to use her kitchen because it is not legal to have a kitchen below a bedroom and she does not want to do that. We were not aware of these rules since we are new to the country and she did not inform us all these situations and they orally agreed to extend the contract every month, so since we have been looking for a property with that convenience due to our situations regarding the visa for which we have applied to extend and our documents are at the home office and we cannot look for a new property but we still have the visa till july we committed to this property. I dont want to share their kitchen but need the cooker as agreed by them, since suddenly they come and say they have to follow the rules and all that, they have been living in this country for many years and they have not given the cooker for others means they knew the laws, so if they had said they cant provide one we could have looked for another property, when we question that she says since we asked them they could not refuse. That lady is so stern. Could anyone help please? advice me on this.
