What is Service Charge and Ground Rent? And What Does Leasehold Mean?

by | Friday 21st Nov 2025 | Mortgage Insights

Flats in London which all have service charges, ground rent, and leashold on them.

If you’re thinking about buying a flat, you’ll quickly come across three terms that can feel a bit confusing at first. These terms are service charge, ground rent, and leasehold. They’re all important, not just for understanding your long-term costs, but also when applying for a mortgage. This guide breaks everything down clearly so you know exactly what you’re signing up for, and why getting the right mortgage advice from specialists like Oportfolio Mortgages can make the process much easier.

What Does Leasehold Mean?

Most flats in the UK are sold as leasehold. This simply means you’re buying the right to live in the property for a set number of years, the length of the lease, but you don’t own the land or the building structure. Instead, the freeholder (or landlord) owns the land and communal areas.

What to Know About Leasehold When Buying a Flat

  1. Lease length matters, Anything below 90 years can start to affect property value and mortgage availability. Below 80 years, extending the lease becomes more expensive and many lenders may be cautious.
  2. You’ll have extra costs. Leaseholders typically pay service charge and ground rent.
  3. Your rights and obligations are set out in your lease, which your solicitor should review in detail.
  4. Mortgage lenders will always ask about lease length because it affects the property’s long-term value, something we at Oportfolio review early so there are no surprises later.

What Is Ground Rent?

Ground rent is a fee leaseholders pay to the freeholder for the land your flat sits on.

It’s usually:

  • A fixed annual amount
  • Sometimes set to increase every 10–25 years
  • Historically low, but can vary depending on the lease

Key Things to Know About Ground Rent

Lenders dislike escalating ground rent clauses (e.g., doubling every 10 years). These can make a mortgage harder to secure. Some new builds now offer peppercorn ground rent, effectively £0, due to recent government reforms. Your solicitor will check the ground rent terms, but your mortgage adviser also needs this information when assessing affordability and lender criteria.

At Oportfolio Mortgages, we help clients identify lender-friendly ground rent terms early to avoid delays.

What Is a Service Charge?

A service charge is a payment leaseholders make to cover the costs of maintaining the building and communal areas. Unlike ground rent, this fee covers actual services provided by the freeholder or management company.

Service charges usually cover:

  • Building maintenance
  • Cleaning of communal areas
  • Lift servicing
  • Gardening
  • Building insurance
  • Repairs and long-term maintenance funds

Important Things Buyers Should Know

Service charges vary widely depending on the building and services offered. They can fluctuate each year, so check both the current charge and any history of increases. Some buildings collect contributions toward a sinking fund, which covers major works like roof replacements. Mortgage lenders do ask about service charges because they affect affordability, another area where having a broker manage the paperwork is extremely helpful.
