Hi pm.e
It would really depend upon the contract of supply between you and the sindow company. Were you dealing directly with the supplier, or were the windows purchased using a finance agreement? If the former, the supplier may have retention of title clauses in their contract which allow them to remove goods which have not been paid for, so long as they have not become incorporated into the fabric of your property, or would cause damage to remove. Clearly the removal of the windows would cause damage.
If the windows were bought using a finance agreement, then your contract is with the finance provider rather than the windows company, who will therefore already have been paid. In which case, it is very unlikely that your windows will be removed.
