What Is Marriage Value in Leasehold Reform — And Why It Could Cost You Thousands

If you own a leasehold property in the UK, you may have heard whispers about “marriage value” — and not the romantic kind. In leasehold terms, marriage value is a crucial concept that can significantly affect how much you pay when extending your lease or buying your freehold.

Let’s break it down, especially how it ties into the Leasehold Reform, Housing and Urban Development Act 1993, and why the 80-year lease mark is a critical deadline.

What Is Marriage Value?

In property terms, marriage value refers to the increase in property value that happens when a leaseholder extends their lease or purchases the freehold. It’s the uplift created by combining the interests of the leaseholder and the freeholder — hence, the term “marriage.”

For example, a flat with a 70-year lease may be worth £250,000, but once the lease is extended to 99 years, it could jump to £280,000. That £30,000 increase? That’s the marriage value — and under current law, you may have to share it with the freeholder.

What the Leasehold Reform Act Says

The 1993 Leasehold Reform Act gives leaseholders the legal right to extend their lease or collectively buy the freehold. But it also allows freeholders to be compensated for their lost interest — and marriage value is part of that compensation.

Here’s what the law says:

• If your lease has more than 80 years remaining, no marriage value is payable. You can extend your lease without paying this extra charge.
• If your lease has less than 80 years left, 50% of the marriage value must be paid to the freeholder as part of the premium.This 80-year threshold is known as the “marriage value cliff edge”, and it’s why many property experts urge leaseholders to extend before crossing it.Why It Matters for Leaseholders

  That 80-year mark isn’t just symbolic — it’s financial.

  Let’s say your lease hits 79 years. Suddenly, extending the lease becomes much more expensive because now you’re paying part of the marriage value. This can mean thousands — even tens of thousands — in extra costs.

Extending early avoids this and can make your property more attractive to buyers or mortgage lenders.

Is Marriage Value Going Away?

There’s good news on the horizon. The UK government has proposed changes to leasehold laws, including the potential abolition of marriage value altogether. If passed, these reforms could make lease extensions more affordable and fair for leaseholders.

However, as of now, marriage value still applies under current law. So if your lease is creeping toward the 80-year mark, it’s wise to act sooner rather than later.

Understanding marriage value isn’t just legal jargon — it’s a real financial consideration for any leaseholder. The 80-year rule is a crucial turning point. If your lease is getting close to that point, talk to one of our solicitors to explore your options.
