Is your house the only one like this?
I would expect that every house of your house type would also be the same, unless the roof is lower in just your house.
If there are others you should consider a class action.
The £6,000 "compensation" is not enough to compensate you for the loss you will suffer in selling price when you try to sell. However, it is probably about right for nuisance and inconvenience compensation.
In my opinion you are correct it is a breach of contract.
I would suggest you avoid all
firms on this list - they work for housebuilders! and recommend you contact:
