The core difference: tenure
The single biggest difference between most flats and houses is tenure, the legal basis on which you own the property. Houses are usually freehold, meaning you own the building and the land it sits on outright, with no time limit and no landlord.
Most flats are leasehold. You own the right to live in the flat for a fixed number of years set by the lease, while a freeholder owns the building and land. That brings ground rent (now banned on most new leases), service charges for shared maintenance, and rules in the lease about what you can and cannot do.
Some flats come with a share of freehold, where leaseholders jointly own the freehold, giving more control. Increasingly, houses on new estates also carry estate rentcharges, so always check tenure rather than assuming.
Flat vs house at a glance
How the two compare on the factors that matter most.
| Factor | Flat | House |
|---|---|---|
| Purchase price | Usually cheaper in the same area | Usually more expensive |
| Tenure | Often leasehold | Usually freehold |
| Ongoing costs | Service charge plus any ground rent | You fund all repairs yourself |
| Space and garden | Less space, often shared outdoor areas | More space, usually private garden |
| Maintenance | Building managed collectively | Entirely down to you |
| Freedom to alter | Restricted by the lease | Greater, subject to planning |
| Long-term growth | Steady but lease-dependent | Often stronger over time |
These are general patterns; a specific flat or house can buck the trend.
When a flat makes sense
A flat is often the better choice if:
- You want to get onto the ladder sooner with a smaller budget.
- You prefer low-maintenance living without a garden to manage.
- Location matters more than space, for example a city centre.
- You travel often and value a lock-up-and-leave home.
- You are happy to budget for service charges in return for managed upkeep.
When a house makes sense
A house tends to suit you if:
- You need more space now or expect a growing family.
- You want a private garden and off-street parking.
- You value freehold control and the freedom to extend.
- You want to avoid service charges and lease restrictions.
- You are buying for the long term and want stronger growth potential.
Always check the lease on a flat
Before buying a flat, review the remaining lease length, the ground rent and the service charges. A lease under about 80 years becomes expensive to extend and can be hard to mortgage, while high or rising service charges hit affordability and resale. Ask for the last few years of service charge accounts.
Houses are not always freehold
Some new-build houses are sold leasehold or carry estate management charges for shared roads and green spaces. Check the tenure and any annual charges in the legal pack, do not assume a house is automatically freehold and charge-free.
