What Makes a Maisonette Different?
A maisonette is a self-contained dwelling that occupies more than one floor of a larger building, with its own private entrance, either directly from the street or from a shared entrance lobby. This distinguishes it from a conventional flat, which is typically confined to a single floor and accessed via a communal staircase.
The term is more common in England and Wales than in Scotland (where "flat" is used for most apartment-type properties). Maisonettes are typically found in converted Victorian or Edwardian houses, purpose-built interwar blocks, and some post-war developments.
Types of Maisonette
| Type | Characteristics |
|---|---|
| Ground floor maisonette | Occupies ground and lower ground floors; often has garden access |
| Upper maisonette | Occupies upper floors; typically lighter but no garden |
| Split-level | Two floors within a larger block; may have communal entrance |
| Converted house pair | House subdivided into two maisonettes; lower and upper |
Tenure, Leasehold or Freehold?
Most maisonettes are sold leasehold, particularly in converted buildings where a freeholder retains the building and land. However, some maisonettes, particularly where a house has been split into just two, may be sold as flying freeholds or with a share of freehold arrangement.
A flying freehold (where part of a freehold property sits above another freehold) can create mortgage difficulties: some lenders will not lend on them, or will only lend with specific legal indemnity insurance in place. Always check the tenure carefully before proceeding.
Key Checks for Maisonette Buyers
Lease Length and Ground Rent
If leasehold, confirm the unexpired lease term. Most lenders require at least 70–85 years remaining at the end of the mortgage term. Ground rent terms should also be checked, doubling ground rent clauses introduced after 2003 can cause valuation and mortgageability issues, though the Leasehold Reform (Ground Rent) Act 2022 has capped ground rents on new leases at zero.
Service Charges and Building Insurance
Unlike a freehold house, the leaseholder of a maisonette pays a service charge to the freeholder for the maintenance of shared structure, roof, and external walls. Review the last three years of service charge accounts and enquire about any planned major works.
Noise and Structure
In a converted house, the floor and ceiling between a lower and upper maisonette may provide little sound insulation. Inspect carefully and ask about noise at different times of day.
EPC and Energy Efficiency
Ground floor maisonettes often have lower EPC ratings due to heat loss through the ground floor and exposed external walls. Upper maisonettes in poorly insulated buildings similarly suffer. Check the EPC rating on Property Passport UK alongside the current asking price to understand the likely energy running costs.
