You can extend your lease at any time. The process usually takes 3 to 6 months.
Most leasehold properties start off with a lease of either 99 or 125 years. When the years left on your lease drop to 80, it can be harder to sell your home.
If your lease were to run out, we would become the legal owners of your home.
To work out how many years you have left on your lease, subtract the number of years since the start date from the length of the lease. You'll usually find the start date in the 'particulars' section.
