The risk in buying property in London is not just whether prices will rise or fall. Before reserving, making an offer, or exchanging contracts, buyers need to be clear on: what obligations come attached to the title and lease, who is responsible for management charges and building works, whether the mortgage valuation checked the property’s condition, and how a new-build contract handles delays and withdrawal.
This article focuses on the pre-transaction checks specific to London and England. It does not repeat the complete home-buying process, nor does it offer legal, financing or investment judgment on any individual property.
First, Distinguish Freehold From Leasehold
Freehold generally includes long-term ownership of both the land and the property; leasehold means holding an interest in the property for the term of the lease, subject to the fees, maintenance, usage and transfer conditions set out in the lease. Leasehold is common for flats in London, and buyers should not look only at the remaining lease term — they should read the full lease and management information.
An initial round of leasehold checks can include:
- The remaining lease term, and the process for extending it;
- The ground rent amount, how it adjusts, and payment terms;
- What the service charge covers;
- The balance and use of any reserve fund or sinking fund;
- Whether there is already a Major Works notice or unpaid charges outstanding;
- Restrictions on subletting, keeping pets, or making alterations to the property.
For regulated long leases granted on or after June 30, 2022, ground rent is generally limited to a nominal peppercorn — effectively zero. However, if a buyer takes over an existing lease that was granted before that date, the original ground rent terms do not automatically disappear. The remaining lease term can also affect financing and lease-extension arrangements, and acceptance standards should be confirmed with the individual lender.
What Information Should You Check for Service Charges and Major Works?
Whether a service charge is chargeable, how it is apportioned, and when it is payable, are all determined first by the lease. Buyers can ask a UK property solicitor or licensed conveyancer to check recent accounts, the annual budget, the reserve fund, insurance information, correspondence from the management company, and any Major Works already planned or in progress.
In England, a Section 20 consultation is generally triggered if qualifying works cost any one leaseholder more than £250, or if a qualifying long-term agreement lasting more than 12 months costs any one leaseholder more than £100 per year. These two thresholds should not be conflated.
If consultation was not carried out correctly, the amount a leaseholder is required to pay may be capped — but a landlord can apply to the tribunal for dispensation under section 20ZA of the Landlord and Tenant Act 1985. So it cannot be assumed that every case where consultation was skipped is automatically limited to £250, or £100 per year. Disputes over the liability or reasonableness of part of a service charge can be referred to the First-tier Tribunal (Property Chamber) — whether that applies depends on the substance of the dispute and the procedure followed.
A Mortgage Valuation Is Not the Same as a Home Survey
A mortgage valuation is a limited inspection arranged by the lender to assess the risk of the loan — its focus is whether the property is sufficient to support the loan. It is not a survey report for the buyer to understand the property’s condition.
A home survey, by contrast, is carried out by a chartered surveyor according to an agreed scope. RICS home surveys come in different levels; the property’s age, construction type, any alterations, and visible defects will affect which level is appropriate. Buyers should not assume that structure, damp, the roof, common parts or future maintenance risk have already been checked simply because the lender has completed its valuation.
EWS1 and Statutory Building-Safety Protections Should Be Kept Separate
The External Wall System form (EWS1) is used mainly for valuation and financing purposes relating to a building’s external wall system. RICS makes clear that EWS1 is not a life-safety certificate for the whole building, and not every building needs one. Whether it is required, whose assessment is acceptable, and whether the document still meets a lender’s requirements, should be checked against the building’s characteristics, valuation guidance, and the individual lender’s instructions.
England’s Building Safety Act 2022 leaseholder protections are a separate statutory regime. It involves conditions such as “relevant buildings,” historical safety defects, and qualifying leases and leaseholders. Qualifying leaseholders can be exempt from paying for the remediation of external wall cladding, while costs for some non-cladding defects may be subject to a cap and payment-plan rules.
So an EWS1 result is not the same as eligibility under the Building Safety Act. When buying a high-rise or multi-storey home in London, these can be checked separately:
- Whether the building has any cladding or historical safety defects;
- Who carried out any existing EWS1 or other external-wall assessment, and when;
- Whether the lender and valuer require this document;
- Whether the property and lease meet the leaseholder-protection conditions on GOV.UK;
- Who is responsible for works already completed, already funded, or still pending.
New-Build and Off-Plan Purchases: What to Check Before Signing
When buying a new-build or off-plan property, whether the reservation fee is refundable depends on the reservation agreement and the applicable consumer code. Buyers should not assume, before reading the terms, that any cooling-off period or refund arrangement is the same across all developers.
A developer may require the buyer to exchange contracts within a fairly short period after reserving. Once contracts are exchanged, the transaction becomes legally binding — the deposit amount, the consequences of a buyer withdrawing, and how a developer’s delay is handled are all governed by the formal contract.
A long-stop date can be written into the contract, allowing a buyer to withdraw if construction delay meets an agreed condition. However, what counts as a delay, how notice is given, how the deposit is handled, and whether the developer can extend the date, must all be read from the specific clauses. Marketing material from an estate agent or developer cannot substitute for an independent review of the contract.
Risks, Documents and Professional Roles at a Glance
| Question the Buyer Wants Checked | Key Document or Information | Suitable Professional Help |
|---|---|---|
| Title, lease term, ground rent and usage restrictions | Title, full lease, management information | UK property solicitor / licensed conveyancer |
| Service charge, reserve fund and Major Works | Accounts, budget, Section 20 notices, management company correspondence | UK property solicitor / licensed conveyancer; relevant professionals to analyze costs or works where needed |
| Property condition, defects and maintenance needs | Home Survey, specialist inspections | Chartered surveyor and relevant building professionals |
| External wall systems and financing documents | EWS1, external-wall assessment, lender requirements | Qualified external-wall assessor, valuer and lender |
| Reservation, deposit, long-stop date and withdrawal terms | Reservation agreement, sale contract, warranty and consumer-code documents | Independent UK property solicitor / licensed conveyancer |
| Mortgage feasibility and mortgage valuation | Lender requirements, loan documents, valuation result | Lender or mortgage broker; a Home Survey is handled separately by a surveyor |
An estate agent can pass on offers and information from the seller or developer, but this does not replace independent legal review, a Home Survey, or a lender’s underwriting decision.
Questions to Check Before You Commit
- Is this freehold or leasehold? What ongoing costs and restrictions will the buyer take on?
- How have the ground rent, service charge and reserve fund changed in recent years?
- Are there any announced, consulted, or still-planned Major Works?
- Beyond the mortgage valuation, what level of Home Survey or specialist inspection does the property need?
- Is EWS1 actually required? Who signs it, and does the lender accept it?
- Do the Building Safety Act leaseholder protections apply to this property and lease?
- Under what circumstances is the reservation fee refunded or forfeited?
- Does the contract include a long-stop date? How are notice, extension, withdrawal and the deposit handled?
- Before exchanging contracts, are financing, legal searches, survey reports and funds all lined up?
FAQ
Q: After buying leasehold, is the ground rent always zero?
Not necessarily. Regulated long leases granted after June 30, 2022 generally use a peppercorn ground rent of zero value; leases granted earlier may still carry their original terms. This should be based on the date the lease was granted and its full wording.
Q: If there was no Section 20 consultation, is the Major Works cost automatically capped?
No. England’s £250 and £100-per-year thresholds are important, but a tribunal can approve dispensation under section 20ZA, allowing a landlord not to complete every consultation requirement. Whether the cost is capped depends on the documents and how the tribunal rules.
Q: Does having an EWS1 mean the building is completely safe?
No. EWS1 is valuation and financing information about the external wall system, not a life-safety certificate for the whole building. Buyers should still separately check fire-risk assessments, remediation plans, statutory protections, and lender requirements.
Q: The lender has already done a valuation — do I still need a Home Survey?
A mortgage valuation mainly protects the lender; its scope is not the same as a buyer’s Home Survey. Whether to arrange one, and at what level, should be judged by the property type, age and condition.
Q: With an off-plan long-stop date, can I always get my full deposit back?
Not necessarily. How the long-stop date is triggered, the right to withdraw, and how the deposit is handled all depend on the contract. Terms should be reviewed by an independent legal professional before signing.
