Flying Freehold Mortgage: Lender Limits, Indemnity Insurance and Checks

A flying freehold is part of a freehold property that sits above, or overhangs, land or a building owned by someone else, such as a bedroom built over a neighbour’s passageway. A flying freehold mortgage is a normal mortgage on that property. Most lenders will lend if the flying part is small, usually 15% to 25% of the floor area, and the legal rights are in place.

Flying freeholds are not rare and they are not a death sentence for a purchase. They are everywhere in Victorian and Edwardian terraces, particularly where a bedroom bridges the covered passage (the ginnel, entry or snicket) running between two houses. You will find thousands of them across Greater Manchester, from Levenshulme and Longsight to Stockport, Oldham, Rochdale and Bolton. The issue is not the building. It is the title. The owner of the room above has no automatic, enforceable way to make the owner below maintain the structure holding that room up. Lenders care about that because it is their security. This guide covers exactly what lenders publish, how the percentage is measured, what your conveyancer checks, and how to stop a flying freehold killing your application.

What is a flying freehold?

A flying freehold is a part of a freehold property that is not built on its own land. It sits over land, or over part of a building, that belongs to a different freehold owner. The classic example is a terraced house where one first floor bedroom extends over a shared passageway or over the ground floor of the house next door. You own that bedroom outright, but you do not own what is underneath it.

Common examples include:

• A bedroom or bathroom above a covered passage or ginnel between two terraced houses.
• A room that extends over part of the neighbouring house’s ground floor, often after old internal alterations.
• An upper floor maisonette held on a freehold title above a shop or another dwelling (a freehold flat, which most lenders treat far more strictly).
• A balcony or bay that projects over a neighbour’s land.

Flying freeholds mostly date from before the modern leasehold system was used to split buildings. In England and Wales, land ownership is layered, so it is legally possible to own a slice of air above someone else’s land. That is exactly why the arrangement causes problems later: the law never gave the owner above a clean right to force the owner below to keep things in repair. Scotland handles shared buildings differently under its own tenement law, so the flying freehold issue is mainly an England and Wales one.

What is a creeping freehold?

A creeping freehold is the reverse of a flying freehold. Part of your property sits underneath land or a building owned by someone else. The usual example is a cellar or basement that extends under the neighbouring house or under the pavement, or a ground floor room that tucks beneath next door’s upper floor.

Lenders treat creeping freeholds in a similar way to flying freeholds, because the question is the same in reverse: if the owner above lets their structure deteriorate, or wants to alter it, what rights do you have to protect the part of your home underneath? In practice creeping freeholds cause fewer declines. A cellar under a neighbour’s house is often non-habitable space and a small share of the floor area, so it rarely breaches a lender’s percentage limit. Several lenders’ Lenders’ Handbook Part 2 entries deal with “flying” and “creeping” freeholds together for exactly this reason.

Title type	What it means	Typical example	How lenders treat it
Standard freehold	You own the building and the land beneath it	Detached or semi-detached house	Standard lending
Flying freehold	Part of your home sits above someone else’s land or building	Bedroom over a shared passage	Usually acceptable up to a percentage limit, with rights and covenants in place
Creeping freehold	Part of your home sits beneath someone else’s land or building	Cellar extending under next door	Usually treated like a flying freehold; small cellars rarely cause declines
Freehold flat	A whole flat or maisonette held on a freehold title within a shared building	Upper maisonette over a shop	Declined by most mainstream lenders; specialist route or conversion to leasehold

Can you get a mortgage on a flying freehold?

Yes. Most mainstream lenders will lend on a house with a flying freehold, as long as the flying part is a limited share of the property and the title gives adequate rights. Leeds Building Society, Accord Mortgages, Virgin Money, Family Building Society, Coventry Building Society and Nationwide all publish criteria that allow it, subject to conditions. Halifax will consider it case by case through its valuer.

The two tests nearly every lender applies are the percentage test and the rights test. The percentage test asks how much of the home is flying. Published limits we checked in September 2026 range from 15% to 25%. The rights test asks whether the title includes rights of support, protection and access for repair, and a scheme of covenants that binds future owners. If the rights are missing, lenders usually accept a flying freehold indemnity insurance policy instead.

Where it gets harder is a large flying element, a freehold flat, or a valuer who comments that the property will be hard to resell. Those cases need the right lender from the start, not a second application after a decline.

Why do mortgage lenders care about flying freeholds?

Lenders care because the part of the home they are lending against depends on a structure they have no control over. If the neighbour below lets the passage roof, walls or foundations deteriorate, the room above can be damaged, and the owner above has no simple way to force repairs.

The legal reason is a long standing rule of English property law. A covenant to do something, called a positive covenant (for example “keep the supporting walls in repair”), binds the original parties but does not automatically pass to later owners. The courts confirmed this in Austerberry v Oldham Corporation in 1885 and again in Rhone v Stephens in 1994, which was itself a flying freehold case. So even if the original builder wrote repair obligations into the deeds in 1890, the current owner below may not be bound by them.

That creates three risks a lender prices in:

• Support: no enforceable duty on the neighbour to maintain what holds your room up.
• Access: no automatic right to go onto the neighbour’s land to repair your own structure. The Access to Neighbouring Land Act 1992 lets you apply to court for access for basic preservation work, but that is slow and costly.
• Resale: future buyers and their lenders will ask the same questions, which can narrow the market for the property.

What does the UK Finance Mortgage Lenders’ Handbook say about flying freeholds?

The UK Finance Mortgage Lenders’ Handbook is the rulebook conveyancers follow when they act for a lender. For England and Wales it tells the conveyancer that if any part of the property comprises or is affected by a flying freehold, or the property is a freehold flat, they must check the individual lender’s Part 2 instructions to see whether that lender accepts it as security.

Where the lender does accept it, the Handbook sets out the standard: the property must have all necessary rights of support, protection and entry for repair, and a scheme of enforceable covenants under which later buyers are required to enter into covenants in identical form. The conveyancer must be able to certify that the title is good and marketable. For flying freeholds, they must also send the lender a plan clearly showing the part of the property affected.

If those requirements cannot be met, the Handbook route is indemnity insurance in place at completion. In practice, very few old terraced titles contain a perfect covenant scheme, so indemnity insurance is how most flying freehold purchases complete. Each lender’s Part 2 entry then adds its own appetite on top, and that is where the percentage limits live.

Which lenders accept flying freeholds, and what are their limits?

Lender limits on flying freeholds typically sit between 15% and 25% of the property, but the wording differs in ways that matter. Some measure floor area, some measure footprint, and some add their own conditions. The table below quotes each lender’s published criteria as we found it in September 2026. Criteria change, so we recheck before every application.

Lender	Published flying freehold limit	Conditions noted	Source checked
Leeds Building Society	Up to 15% of the property extending over another	Valuer must state re-saleability is unaffected; also covers freehold flats within the 15%	Lending criteria effective 24 August 2026
Accord Mortgages	15% or less of the whole property footprint	Measured on footprint, not floor area	Accord criteria page, September 2026
Virgin Money	No more than 15% of the overall floor area	Indemnity policy covering repair or maintenance liabilities, adequate rights of support and mutually enforceable repairing covenants	Buy-to-let property criteria, September 2026
Family Building Society	Up to 20% of gross floor area	Maximum acceptable percentage of gross floor area	Buy-to-let criteria, September 2026
Coventry Building Society	No more than 25% of the floor area	Plan showing the affected part required	Lenders’ Handbook Part 2 entry, September 2026
Halifax	No fixed percentage published	Generally not acceptable, but considered where only part of the property is flying; the valuer’s Property Risk Assessment decides	Halifax Intermediaries criteria, September 2026
Nationwide	No percentage published on its criteria page	Flying freehold listed as acceptable; valuer and conveyancer checks apply	Nationwide for Intermediaries property criteria, September 2026

Two points jump out. First, the same room can pass at Coventry and fail at Leeds, Accord or Virgin Money. Second, a lender with no published percentage is not automatically more generous; it simply hands more of the decision to the valuer. Picking the lender before the valuation is booked is the single biggest lever you have. Some broker sites also list limits for Barclays, NatWest and TSB; we could not confirm those on the lenders’ own criteria pages in September 2026, so they are not in the table.

How is the flying freehold percentage worked out? A worked example

The percentage is the flying area divided by the property’s total area, measured the way that lender specifies. Most use floor area; Accord uses footprint. On the same house those two methods can give very different answers, which is why the measurement basis matters as much as the headline limit.

Take a typical two up, two down terrace in Stockport with a bedroom that extends over the shared passage to next door.

Measurement	Area
Ground floor internal area	38.0 sq m
First floor over the house’s own land	38.0 sq m
First floor section over the passage (3.2 m x 3.0 m)	9.6 sq m
Total floor area (38.0 + 38.0 + 9.6)	85.6 sq m
Footprint seen from above (38.0 + 9.6)	47.6 sq m

Floor area test: 9.6 ÷ 85.6 = 0.112, so the flying element is 11.2% of floor area. That passes the 15% limits at Leeds and Virgin Money, the 20% limit at Family Building Society and the 25% limit at Coventry.

Footprint test: 9.6 ÷ 47.6 = 0.202, so the flying element is 20.2% of the footprint. That fails a 15% footprint limit such as Accord’s, even though the house sails through on floor area.

Now make the flying room bigger. If the section over the passage were 4.5 m x 4.0 m, that is 18.0 sq m. Total floor area becomes 38.0 + 38.0 + 18.0 = 94.0 sq m, and 18.0 ÷ 94.0 = 19.1%. That fails every 15% lender, passes Family Building Society at 20% by a whisker and passes Coventry at 25%. Same street, same buyer, a completely different lender shortlist. Ask the valuer or your conveyancer for the measurements early, and run the numbers before you choose the lender, not after.

How does flying freehold indemnity insurance work?

Flying freehold indemnity insurance is a one-off policy that covers you, and your lender, against financial loss caused by the missing rights in the title. It typically pays out if the lack of support, access or repair covenants causes a loss in the property’s value or costs you money, for example if a neighbour’s failure to repair damages your room, or if a later buyer’s lender demands something the title cannot provide.

Key points to understand:

• It is usually cheap. The premium is normally a single payment, often in the low hundreds of pounds, depending on the property value and the insurer. Your conveyancer arranges it and the cost goes on their completion statement.
• It is often the seller’s cost. Buyers’ conveyancers regularly ask the seller to provide it, since the defect is in the seller’s title. That is a negotiation point, not a rule.
• It passes on. Policies normally cover successors in title and their lenders, which helps on resale and remortgage.
• It can be invalidated. Most policies are void if you contact the neighbour about the missing rights before the policy is in place, because that can trigger the very dispute the insurer is covering. Talk to your conveyancer before you knock on next door.
• It does not fix the building. It covers a legal and financial risk. It does not pay for general wear and tear, and it does not create a right to go onto the neighbour’s land.

What is a deed of mutual covenant, and do you need one?

A deed of mutual covenant is a legal agreement between you and the neighbour whose land your flying freehold sits over. Each side promises to keep their part of the structure in repair, gives the other access to carry out repairs, and agrees to insure. The critical clause requires each owner to make any future buyer sign an identical deed, which creates a chain of covenants that keeps the obligations alive through later sales.

This is the fix the Lenders’ Handbook points towards, because it gives the “scheme of enforceable covenants” lenders want. It is also the most robust long term solution for your own protection. The catch is that it needs a cooperative neighbour and both sides need legal advice, so it takes time and costs legal fees. It is rarely done in the middle of a purchase with a completion date looming.

Other routes exist. An estate rentcharge can make positive covenants enforceable against later owners, and on some titles the neighbours agree to restructure the flying section as a long lease, which brings it into the familiar leasehold framework. For most buyers of a terraced house with a room over a passage, indemnity insurance is the practical answer at purchase, with a deed of mutual covenant as a longer term project if the neighbour is willing.

What does your conveyancer check on a flying freehold?

Your conveyancer’s job is to establish exactly what is flying, what rights the title contains, and whether your lender’s Part 2 instructions are met. They report to both you and the lender, and the lender will not release funds until it is satisfied.

Check	Why it matters	What the lender wants to see
Title plan and register	Shows which parts of the building sit on or over which title	A plan clearly showing the flying or creeping part
Rights of support and protection	Confirms the structure below must continue to support your room	Express or clearly implied rights in the title
Rights of entry for repair	Lets you access the neighbour’s land to maintain your part	A documented right of access
Covenants and who they bind	Positive covenants do not automatically bind later owners	A scheme of enforceable covenants, or indemnity insurance
Extent of the flying part	Drives the lender’s percentage test	Measurements within the lender’s limit
Indemnity insurance	Covers missing rights where the title falls short	A policy in place at completion covering you and the lender
Seller’s disclosures	Flags any disputes, repair issues or neighbour problems	No live dispute over the passage or structure

The valuer does a separate job. They report the flying element on the mortgage valuation and comment on marketability. Our mortgage valuation guide explains what the valuer looks at and how to handle a down valuation or an adverse comment.

Is a flying freehold a problem when you buy?

Usually not a serious one, provided the flying element is modest, the building is in decent repair and the right lender is chosen. For many buyers a flying freehold is a paperwork point that adds a policy and a few emails to the conveyancing, not a reason to walk away.

The real flying freehold problems are practical rather than legal:

• Condition of the passage. Look at the structure underneath. Cracked lintels, damp in the passage ceiling or a sagging beam matter more than the title wording.
• Neighbour relations. A cooperative neighbour makes repairs and a deed of covenant easy. A hostile one makes both hard.
• Lender choice. The wrong lender can decline on percentage alone, costing you a valuation fee and weeks.
• Resale. The next buyer faces the same checks. If you solve the title now with a deed of mutual covenant, you make the house easier to sell later.

If you are a first-time buyer looking at older terraces, you will meet flying freeholds regularly, because they sit in exactly the price bracket many first-time buyers target. If you are moving home and selling a flying freehold at the same time, our home mover mortgage guide covers how to keep both sides of the chain on track.

Can you remortgage a flying freehold property?

Yes. Remortgaging a flying freehold is usually simpler than buying one, because the title has already been accepted once and an indemnity policy is often in place. The route you take decides how much gets checked again.

A product transfer with your existing lender normally involves no new valuation and no new legal work, so the flying freehold is not reassessed. That makes it the lowest friction option when the rate is competitive. A remortgage to a new lender means a fresh valuation and a fresh conveyancing check against that lender’s Part 2 instructions. The new lender’s percentage limit applies, not the old one, so a house bought with a Coventry mortgage at 22% flying cannot move to a 15% lender.

Before you remortgage, find your purchase file. Your conveyancer will want the original indemnity policy, the title plan and any deed of covenant. Most indemnity policies extend to successors in title and their lenders, so the existing policy usually satisfies a new lender. If the file is missing, a new policy is typically straightforward to arrange, provided nobody has contacted the neighbour about the defect.

Why do flying freehold mortgage applications get declined, and what is the fix?

Most flying freehold declines are avoidable, because they come from sending the case to a lender whose criteria never fitted. Here are the patterns we see and how to deal with each.

Reason for decline	What it looks like	The fix
Over the percentage limit	Flying room is 19% of floor area; lender caps at 15%	Measure first, then place with a lender whose limit and measurement basis fit, such as a 20% or 25% lender
Wrong measurement basis	Passes on floor area but fails on footprint	Avoid footprint based lenders for that property
Freehold flat, not a flying room	Whole maisonette held freehold over a shop or another flat	Specialist lender, or convert the title to a long lease before the mortgage
Adverse valuer comment	Valuer says saleability is affected	Challenge with evidence of comparable sales on the same street, or move to a lender whose valuer takes a local view
Missing rights, no insurance	Title has no support or access rights and no policy	Indemnity insurance at completion, or a deed of mutual covenant
Policy invalidated	Buyer spoke to the neighbour about the defect first	Negotiate a deed of mutual covenant or find a lender that accepts the title as it is
Poor condition of the structure below	Damp or movement in the passage	Structural report, agreed repairs or a retention; see our non-standard construction mortgage guide for how lenders handle structural issues

Flying freeholds often travel with other old property issues. If the same survey flags invasive plants in the garden or next to the passage, our Japanese knotweed mortgage guide covers what lenders require there.

Illustrative Knox case: a passage bedroom in a Levenshulme terrace

This is an anonymised, illustrative case based on the type of flying freehold scenario we handle; details are simplified. A first-time buyer agreed a purchase on a three bedroom Victorian terrace in Levenshulme. The smallest bedroom sat over the shared entry to next door. Their bank’s decision in principle was fine, but the bank’s criteria capped flying freeholds at 15% of footprint.

We asked the estate agent for the floor plan before booking any valuation. The flying bedroom measured 2.9 m x 3.4 m, 9.9 sq m, on a total floor area of 88 sq m and a footprint of 54 sq m. That is 11.3% of floor area but 18.3% of footprint. On footprint it would have failed. We placed the case with a lender that measures on floor area with a higher limit, told the conveyancer up front that indemnity insurance would be needed, and asked them to request that the seller fund the policy. The valuation came back clean, the seller agreed to pay for the policy, and the case completed without a second valuation fee or a lost month.

The lesson: the property was never the problem. Checking the measurement basis before the application was the whole job.

Frequently asked questions

What is a flying freehold in simple terms?

A flying freehold is part of your freehold home that sits above land or a building owned by someone else. The usual example is a bedroom over a shared passage between two terraced houses. You own the room, but not the structure underneath it, and you may have no enforceable right to make the neighbour maintain it.

Can I get a mortgage on a house with a flying freehold?

Yes. Leeds, Accord, Virgin Money, Family Building Society, Coventry and Nationwide all publish criteria allowing it, and Halifax considers it case by case. Most want the flying part to be 15% to 25% of the property, plus adequate rights or an indemnity insurance policy at completion.

What percentage of flying freehold will lenders accept?

Typically 15% to 25%. In September 2026, Leeds, Accord and Virgin Money published 15%, Family Building Society 20% of gross floor area and Coventry 25% of floor area. Check how the lender measures it: Accord uses footprint, which can produce a much higher percentage than floor area on the same house.

How much does flying freehold indemnity insurance cost?

It is usually a one-off premium, often in the low hundreds of pounds, depending on the property value and insurer. Your conveyancer arranges it. Buyers often ask the seller to pay, because the defect sits in the seller’s title. Do not contact the neighbour about the issue first, as that can invalidate cover.

What is the difference between a flying freehold and a creeping freehold?

A flying freehold sits above someone else’s land or building, such as a room over a passage. A creeping freehold sits below it, such as a cellar that extends under the house next door. Lenders treat both in a similar way, but small creeping freeholds rarely cause declines.

Are flying freeholds common in Greater Manchester?

Yes. They are common in Victorian and Edwardian terraces across Greater Manchester, Lancashire and Yorkshire, where bedrooms were often built over the ginnel or entry between houses. Areas such as Levenshulme, Longsight, Stockport, Oldham, Rochdale and Bolton have many examples. Most are mortgageable with the right lender.

Can I remortgage a flying freehold property?

Yes. A product transfer with your current lender usually needs no new valuation or legal checks. A remortgage to a new lender means a new valuation and title check against that lender’s limit. Keep your original indemnity policy and title documents, as they usually satisfy the new lender.

Should I buy a house with a flying freehold?

Often yes, if the flying part is small, the structure beneath is sound and the right lender is lined up. The risks are practical: repairs that depend on a neighbour, and resale checks for the next buyer. A deed of mutual covenant with the neighbour is the strongest long term fix.

If you are looking at a property with a flying or creeping freehold, book a free, no-obligation discovery call. We will check the measurements against current lender criteria before you spend money on a valuation.
