Frequently Asked Questions: Flying Freehold Mortgage Lending
Statutory conveyancing questions on lender percentage tolerance, deeds of covenant, and title insurance.
A flying freehold occurs when part of a freehold property extends over or under an adjoining property owned by someone else. Common examples include: a bedroom extending above a neighbour's garage or archway (flying freehold), or a cellar extending beneath a neighbour's hallway (sometimes termed a 'creeping' freehold).

Is It Difficult to Get a Mortgage on a Flying Freehold Property in the UK?
It can be challenging, but getting a mortgage on a flying freehold is entirely achievable with major UK high street lenders if the flying portion represents 15% or less of the gross internal floor area. Lenders including Halifax, Nationwide, Santander, and Barclays will lend on flying freeholds up to 15%–25% provided the conveyancer confirms adequate rights of support and shelter, or procures a standard flying freehold title indemnity insurance policy (£150–£350). However, conservative lenders like Virgin Money or Coventry Building Society decline flying freeholds regardless of percentage.
Should I Buy a House With a Flying Freehold? (Pros, Cons & Resale)
Yes, provided the flying freehold represents a minor percentage (under 15% of floor area) and is fully protected by a title indemnity insurance policy or a Deed of Mutual Covenant. Flying freeholds are common in historic market towns and Georgian/Victorian terraces. However, you should commission a RICS Level 3 Full Building Survey to inspect the shared party floor structure, budget £150–£350 for title indemnity insurance, and recognize that future resale may exclude buyers whose lenders have strict zero-tolerance policies.
Why Do UK Mortgage Lenders Dislike Flying Freeholds?
Mortgage lenders dislike flying freeholds because under English common law (the fundamental rule in Rhone v Stephens [1994] and Austerberry v Oldham Corporation [1885]), POSITIVE COVENANTS DO NOT RUN WITH FREEHOLD LAND. If your neighbour's supporting walls, ground floor, or roof collapse or rot, you have no legal power to compel them to spend money on repairs. If the supporting building collapses, the bank's mortgage security literally disappears, leaving the lender with an unrecoverable loan.
What Are the Real Disadvantages and Risks of a Flying Freehold?
The primary disadvantages and risks of owning a flying freehold include: (1) Inability to force neighbours to carry out essential structural maintenance underneath or above your living space, (2) Insurance coverage disputes where separate home insurers argue over who is liable for damaged party joists or leaking ceilings, (3) Restricted mortgage eligibility, which narrows your pool of prospective buyers upon resale, (4) Potential property devaluation of 5% to 15% for substantial overhangs, and (5) Reliance on Court orders under the Access to Neighbouring Land Act 1992 if a neighbour refuses entry for maintenance.
What to Do If a Flying Freehold Is Not on the Land Registry Title Deeds
If a physical flying freehold is discovered during surveyor inspections but is NOT recorded on the HM Land Registry Title Register or title plan, you must: (1) Have your conveyancer inspect both your title and the adjoining neighbour's Title Register (filed plan) to check whether the horizontal boundary is shown by green tinting or broken lines, (2) Procure a specialist Flying Freehold Title Indemnity Insurance policy (£180–£350) which protects you and your lender against absence of easements on the register, and (3) In complex cases, negotiate a Deed of Rectification with the neighbour under Schedule 4 of the Land Registration Act 2002.
Flying Freehold Over Shared Passageway or Archway: Legal Rules
A bedroom situated over a shared pedestrian passageway ('tunnel', 'vennel', or 'ginnel') or vehicular carriage archway between terraced houses is the most common flying freehold in England and Wales. Under Section 62 of the Law of Property Act 1925, rights of support, shelter, and pedestrian passage are typically implied into the title. Major mortgage lenders (including Halifax, Nationwide, and Barclays) routinely approve passageway overhangs provided: (1) The overhang constitutes a minor portion of the home (under 15%), (2) A standard £150 indemnity policy is in place, and (3) The passage is not subject to structural subsidence.
Who Owns the Land Under a Flying Freehold? (Airspace vs Subsoil)
Under UK property law, the ground-floor neighbour owns the subsoil, foundations, and airspace up to the underside of the upper floor joists. The flying freehold owner owns the upper horizontal airspace stratum (including internal floors, ceilings, walls, and roof). The legal boundary separating the two freehold titles is typically the horizontal median line running through the middle of the supporting timber floor joists, unless an express deed specifies otherwise. Neither party has the unilateral right to cut, alter, or remove supporting structural joists.
