Thank you for the clarification.
I am assuming that you are beyond the first 3 months of your tenancy otherwise you cannot give notice until that point in time.
If this is the position then you will need to wait for the first 3 months of the Tenancy to expire and then you can provide the 3 months notice from that point.
If you have gone beyond the 3 months of the Tenancy then you can give 3 months' notice as per clause 7.0. however, you are duty-bound by the terms of clause 7.2 and thus will have to pay for those charges incurred by the landlord.
If you do not pay the same it is most likely that the Landlord will take Court Proceedings against you and in all likelihood will be successful in obtaining a judgement against you, for those charges under clause 7.2 that are judged to have been reasonably incurred in the opinion of the Court.
If those costs are below £10,000 then the matter will be dealt with in the Small Claims Court, if they are over £10,000 then they will be dealt with in the realms of the Fast Track of the County Court.
Therefore, in short if you still want to leave then your best option is to find an alternative tenant so as to keep the Landlords costs to a minimum of changing the tenancy.
I hope that assists. If you need a CALL to discuss and more in-depth advice, then please let me know.
