Lease Extensions in Sevenoaks: What Flat Owners Should Know

Sevenoaks remains one of Kent’s most sought-after towns, thanks to its green spaces, schools, and swift trains into London. But along with its growing popularity, many leasehold flats in Sevenoaks especially those built in the 1980s and 1990s are now facing an issue many owners overlook: shortening leases.

If your lease has fewer than 90 years remaining, it’s worth paying close attention. Once it dips below 80 years, the cost to extend jumps significantly, and it can affect everything from your flat’s value to how easily it can be sold or remortgaged.

Why It’s Crucial Not to Delay

Most flats were originally sold on 99- or 125-year leases. While that might sound long enough, time catches up quickly — and leases in the low 80s are now common in Sevenoaks areas like Bat & Ball, Riverhead, and St John's.

Once your lease hits 80 years or fewer, marriage value kicks in — a legal requirement that increases what you must pay to the freeholder. This additional charge can run into the thousands, so extending your lease before reaching this threshold can save you money and stress.

The Process, in Brief

Extending your lease typically follows a statutory route under the Leasehold Reform, Housing and Urban Development Act 1993, if you’ve owned your flat for at least two years. Here's how it works:

  1. Valuation – A formal lease extension valuation is carried out by a qualified surveyor (like us) based on ground rent, lease length, and property value.

  2. Serving Notice – Your solicitor issues a Section 42 notice to the freeholder.

  3. Negotiation – The freeholder replies with their counter-premium, and negotiations begin — backed by our valuation.

  4. Legal Completion – Once agreed, solicitors finalise the new lease.

What Will It Cost?

The final premium depends on several factors:

  • Remaining lease length

  • Annual ground rent

  • Market value of the flat

  • Whether marriage value applies

In addition to the premium, budget for:

  • A surveyor’s report (we offer fixed fees)

  • Solicitor’s fees

  • The freeholder’s legal and valuation costs

Tip: It’s nearly always cheaper to extend at 82 years than to wait until you hit 78.
