If you are a leaseholder, then there is the option of attempting to purchase the freehold of your property. If your property is flat, you may be able to buy a share of the freehold, which you would own alongside the other flat owners. If the property is a house you may be able to buy the full freehold.
This can be a lengthy and expensive process, and it’s well worth getting expert legal advice.
