When the Lease Does Not Include the Room You Thought You Bought

A room shown in an estate agent’s particulars may feel like an unquestionable part of the flat being purchased. However, the legal extent of a leasehold property is determined by the lease, not by the sales description or the way the property is being occupied.

A striking Legal Ombudsman case illustrates what can happen when those descriptions do not match. The buyer believed she had purchased a converted apartment containing an attic room. It was only when she later tried to sell that she discovered the lease did not include that room at all.

The result was not simply an awkward enquiry from the buyer’s solicitor. The Ombudsman reported losses approaching £50,000.

The attic room that did not belong to the flat

The case appeared in the Legal Ombudsman’s report Losing the Plot: Residential Conveyancing Complaints and Their Causes.

The purchaser had instructed a conveyancer when buying the leasehold flat. The sales particulars presented the converted attic room as part of the apartment, and the buyer apparently proceeded on that basis.

When she later decided to sell, she discovered that the legal demise under the lease did not include the attic room. In other words, she had been using and attempting to sell space that she did not legally own under the lease.

According to the Ombudsman’s account, the consequences included:

• a retrospective valuation indicating that the buyer had overpaid by £25,000;
• a payment of £10,000 to the freeholder;
• legal expenses;
• costs associated with the unauthorised use of the attic; and
• the expense of returning the attic to its previous condition.

The Ombudsman concluded that the conveyancer had failed to advise the buyer that the lease was clearly inconsistent with the sales particulars.

Why the estate agent’s particulars are not enough

An estate agent describes the property being marketed. The lease defines the legal interest being sold.

Those documents are not interchangeable. A room may be physically accessible from the flat, used exclusively by its occupier and presented as part of the accommodation while still falling outside the area legally granted by the lease.

The discrepancy may concern an attic, basement, roof terrace, garden, parking space, storage area or part of a converted building. In each case, the first question is whether the lease and its plan include the relevant area and grant the rights needed to use it.

Ownership of the space is only the first question. Even where loft space is included within the legal demise, converting or altering it may still require the freeholder’s consent under the lease. The Lexsure report Loft Space Demised but Still Requiring a Licence for Alterations explains why inclusion of the space within the lease does not necessarily authorise the works carried out there.

This is one reason why a leasehold purchase cannot safely be treated as a routine examination of standard clauses. Our earlier article on leasehold problems buyers discover too late considers the wider range of difficulties that may remain unnoticed until the owner comes to sell or remortgage.

What should the conveyancer compare?

The conveyancer is not ordinarily expected to inspect or measure the property personally. Nevertheless, the transaction documents may contain differences that require investigation or explanation.

Depending on the circumstances, the relevant material may include:

• the property description in the lease;
• the lease plan and any colouring or edging used on it;
• the registered title and filed plan;
• the contract and official copies;
• the estate agent’s sales particulars;
• the seller’s property information;
• replies to leasehold enquiries;
• information supplied by the buyer about the layout;
• any valuation or survey describing the accommodation; and
• any licence for alterations, freeholder’s consent, planning permission or building regulations documentation.

The buyer also has an important role. If a room, garden, parking space or storage area is particularly important, that should be made clear to the conveyancer. A plan should not be approved simply because the coloured outline looks approximately correct.

What should a leasehold Report on Title explain?

A Report on Title should do more than reproduce parts of the lease. It should enable the buyer to understand what is being acquired and identify any material limitation or uncertainty.

Where the circumstances require it, the report should make clear:

• which rooms and other areas fall within the legal demise;
• whether any part used with the flat is excluded;
• whether rights are required over stairs, corridors, roofs or adjoining areas;
• whether the loft or other relevant space forms part of the legal demise and, separately, whether any conversion or alterations received the consent required by the lease;
• whether planning permission or building regulations approval was required and evidenced;
• whether the lease plan appears consistent with the property as described; and
• what effect any discrepancy may have on value, mortgageability and a future sale.

The SRA has previously drawn attention to inadequate leasehold reporting. Our article on inadequate leasehold Reports on Title remains relevant because a lengthy report is not necessarily an effective one. The critical information must be identified, explained and brought to the client’s attention.

Three different attic and loft problems

An attic conversion can raise several separate legal questions. They should not be treated as though they are the same problem.

• Ownership: Does the attic or loft space form part of the property legally granted by the lease?
• Leasehold consent: Did the lease require the freeholder’s consent or a formal licence for the conversion and alterations?
• Public approvals: Were any necessary planning permission and building regulations approvals obtained?

A satisfactory answer to one question does not resolve the others. Loft space may be included in the lease but converted without the freeholder’s consent. Alternatively, the conversion may have building regulations documentation even though the space itself falls outside the legal demise.

Each issue may require a different solution and may have a different effect on the property’s value, mortgageability and future sale.

Can the defective lease be corrected?

A deed of variation may sometimes be used to bring an omitted area within the lease or correct an inadequate description. That is not an automatic solution.

The freeholder and other affected parties may need to agree. A premium may be demanded. Existing mortgage lenders may need to consent, and the variation may require registration at HM Land Registry. If the omitted area belongs to someone else or affects other leases in the building, the position may be more complicated.

A deed of variation correcting the demise will not necessarily regularise historical alterations. A separate retrospective licence for alterations may be required. Planning and building regulations issues must also be considered independently.

Indemnity insurance may be proposed for some lease defects, but insurance does not rewrite the lease, transfer ownership of an excluded room or provide retrospective approval for physical works. Whether it is suitable depends on the precise defect, the policy wording and the requirements of the relevant mortgage lender.

Mortgage lender requirements can change

A lease can be legally effective between landlord and tenant while still containing provisions that concern a mortgage lender. Lenders may have requirements dealing with inadequate lease terms, deeds of variation and whether indemnity insurance is acceptable.

Those requirements are not uniform and they change over time. The Lexsure Lender Archive defective leases page records that 113 lender brands changed their defective lease requirements in England and Wales between 2009 and 2026, producing 303 substantive topic level changes.

That historical evidence can matter where a problem is discovered years after the purchase. The relevant question is not simply what lenders require today, but what the buyer’s lender required when the original transaction took place.

The lender’s requirements are only one part of the evidence. The lease, Report on Title, enquiries, mortgage offer, correspondence and advice given to the buyer must also be considered.

What if the problem is discovered when selling?

The first step is to identify the exact legal discrepancy. Obtain the lease, lease plan, registered title and any supplemental deed. Compare those documents with the physical layout and the way the property was described when it was purchased.

The original purchase file may show:

• whether the discrepancy was identified;
• what enquiries were raised;
• what the seller or freeholder said;
• whether the freeholder had licensed the conversion;
• whether planning and building regulations evidence was obtained;
• whether a deed of variation or insurance policy was considered;
• what was reported to the mortgage lender; and
• what advice was given to the buyer.

The existence of a defect does not by itself establish negligence. The documents available at the time, the scope of the conveyancer’s instructions, the information supplied by the buyer and the advice actually given all need to be considered. Questions of loss and applicable time limits also require individual legal advice.

The lesson from the attic room case

The physical appearance of a property does not establish the legal extent of what is being purchased. Where the lease, plan and sales description do not tell the same story, that difference needs to be investigated before the buyer commits to the transaction.

Even where the space is included within the lease, a separate question remains about whether its conversion was properly authorised. Ownership of the loft, permission from the freeholder and compliance with planning and building regulations requirements are related but distinct matters.

For the buyer in the Ombudsman case, the problem only became apparent when she tried to sell. By then, a discrepancy that might once have been capable of investigation or negotiation had become an expensive obstacle involving ownership, value and marketability.

A clear Report on Title should help prevent that outcome by answering one of the most basic questions in any purchase: exactly what is the buyer acquiring, and are they entitled to use it in its present form?
