Lease covenants can be enforced through the First Tier Tribunal (formally [I mean formerly - ooops] the Land Valuation Tribunal)
Decisions at the First Tier Tribunal are here:
http://www.residential-property.judiciary.gov.uk/search/decisions_browse.jsp
--> Select LVT and a region of your choice, then click "Browse".
--> The case sub-type is "Forfeiture" (This is because the ultimate penalty for a breach of covenant is property forfeiture; don't be alarmed: if the FTT finds against you, simply cease the breach and the matter will end there).
--> Click on an authority and year of your choice.
Trawl through the thousands of cases to look for a case similar to yours, and read the findings of the tribunal.
I think that is costs ÂŁ500 to bring a case to the FTT [edit: the fee is ÂŁ200], and there is no requirement for legal representation (a solicitor might argue otherwise). As there is no requirement for legal representation, legal costs are not usually awarded, but it is my understanding that the ÂŁ200 fee is usually borne by the losing party. BE WARNED - solicitors are paid at a FTT win or lose, they have no incentive to warn you away from litigation or to advise you to represent yourself. A FTT will usually consist of three members, one a lawyer, one a surveyor and one a layman, sometimes there will be one person sitting alone. They will make decisions based on the facts. Present the facts as you see them and there is no need for representation.
The FTT is obliged to follow rulings of higher courts, but can disregard the decisions of previous FTT rulings.
As someone else has pointed out, it would be useful to see the exact wording, including punctuation, of the covenant.[/QUOTE
Thank you for all of this, our solicitor has the documentation but we are contacting them today
