A lease extension quote can look reassuringly simple: one figure for the premium, another for professional fees, and a promise to get the matter moving. But if you compare lease extension quotes line by line without checking what sits behind them, the cheapest option can quickly become the most expensive and time-consuming route.
For a flat owner, this is about protecting a valuable asset and avoiding a process that drifts for months. For a freeholder or managing portfolio owner, it is about maintaining control, responding efficiently and reducing avoidable administration. A proper comparison should show you not only what you may pay, but who is doing what, when costs can change and how the matter will be managed from first valuation to completion.
Compare lease extension quotes on scope, not headline price
Lease extensions involve several moving parts. The premium payable to the landlord is separate from the costs of securing the extension. Those costs may include valuation, legal work, landlord engagement, notice preparation, registration and, where applicable, the landlord’s reasonable professional costs.
That means two quotes with very different totals may not be offering the same service. One provider may quote only for an initial valuation, while another may include case management, a RICS-registered valuer, negotiation support and liaison with the parties. Neither approach is automatically wrong. The issue is whether you can see the difference before instructing anyone.
Ask each provider to state clearly what is included, what is excluded and which costs are estimates rather than fixed fees. If the wording is vague, assume you will need a clearer answer. Leasehold work is technical enough without discovering halfway through that a necessary stage was never included in the original price.
Separate the premium from the professional fees
The lease extension premium is the payment made to the landlord for the new lease terms. It is not a service charge and it is not normally a fixed amount that can be known with certainty before a valuer has reviewed the property and lease.
A credible estimate should explain the assumptions used. These may include the flat’s market value, current ground rent, unexpired lease term, local evidence and, crucially, whether the lease has dropped below 80 years. Once a lease is below 80 years, marriage value can apply under the current statutory framework, often increasing the premium materially.
Professional fees should be set out separately. This lets you compare the cost of advice and administration without confusing it with the price of the interest being acquired. It also makes it easier to see whether a low initial fee is being offset by extra charges later in the process.
Check which route the quote assumes
A quote should make clear whether it is based on a statutory lease extension, an informal negotiated deal, or an assessment of both options.
The statutory route gives qualifying leaseholders a formal legal framework and prescribed terms, but it has procedural requirements and timescales. An informal extension can sometimes be agreed more quickly, but the landlord may propose different terms, including ground rent provisions that deserve careful scrutiny. The right route depends on the lease, the parties’ appetite to negotiate and the terms available – not simply on which route appears cheaper at the start.
Leasehold reform is changing the landscape, including through the Leasehold and Freehold Reform Act 2024. The timing and implementation of changes matter, so avoid advice that treats future reform as a reason to ignore an existing short lease. A quote should deal with your position now while recognising where the law may affect the strategy.
What a useful lease extension quote should show
A good quote does more than supply a total. It gives you a practical map of the work ahead. You should be able to identify who will value the flat, who will handle legal notices or documentation, how negotiations will be managed, and who is responsible for keeping the matter progressing.
Look for a clear explanation of the following areas:
- the estimated premium range and the valuation assumptions behind it;
- your own valuation, legal and management fees;
- likely landlord costs and whether they are included, estimated or payable separately;
- disbursements such as Land Registry fees, notice fees and any tribunal-related costs if matters become disputed;
- the service stages, the named responsibility for each stage and the likely timescale.
The final point is often overlooked. A provider may be excellent at valuation or legal drafting but leave you to coordinate the rest. That can work for an experienced landlord with an established team. It is less attractive for a leaseholder who wants one organised process and regular, intelligible updates.
Be wary of false certainty and unusually low estimates
A lease extension is not a product with one universal price. The value of the flat, lease length, ground rent clause, comparable evidence, landlord identity and route chosen can all affect the outcome. A sensible estimate will be evidence-led and will explain where the range could move.
Be cautious if a quote promises a premium with no caveat, particularly where no lease or property details have been reviewed. Equally, a quote that appears very low may exclude the valuer’s work, the landlord’s costs, negotiation, or the legal stages required to complete the transaction.
That does not mean the highest quote is best. Higher fees should earn their place through a defined service, relevant expertise and better management of risk. The aim is value and control, not merely the lowest opening number.
Ask how costs are controlled if the case becomes difficult
Most lease extensions progress without a tribunal. Even so, a professional quote should explain what happens if valuation negotiations stall, documents are delayed or eligibility is disputed.
Ask whether further work requires your approval before charges are incurred. Find out whether there is a fixed-fee element, a capped fee, or hourly charging after a certain point. You should also know how frequently you will receive updates and whether there is one point of contact coordinating the matter.
For landlords, the same discipline applies in reverse. A streamlined quote should show how leaseholder enquiries, valuation instructions, legal documents and internal approvals will be handled. A fragmented process can create delay, inconsistent records and unnecessary professional spend across a portfolio.
Compare the people and process behind the figures
A lease extension quote is only as reliable as the people delivering it. Check that valuation work is undertaken or supported by an appropriately qualified RICS-registered valuer where needed, and that legal work is handled by solicitors experienced in residential leasehold matters.
Experience matters because small details can have long-term consequences. An informal deal with an attractive upfront premium may contain an escalating ground rent clause. A statutory notice served incorrectly can create delay and extra cost. A valuation that does not properly reflect the lease terms can make a negotiation harder than it needs to be.
You should also assess how the provider communicates. Do they explain the jargon in plain English? Have they identified the information needed before giving a firm view? Are they open about costs that cannot be fixed at the outset? Clear answers are usually a better sign than a sales pitch built around certainty.
A managed service can reduce the burden of appointing and chasing several separate parties. Lease Plus 90 is built around that practical need: bringing the process into a clearer structure while keeping costs, responsibilities and progress visible. For some clients, a fully managed route will be the right fit; others may only need a valuation or targeted support. The key is choosing a service level that matches the complexity of the case.
The documents that make quotes more accurate
Before accepting any estimate, provide the documents that allow advisers to assess the position properly. At minimum, this usually means the lease, property address, current ground rent and service charge information, and details of any previous contact with the landlord.
If available, share the title register, information about planned sale or remortgage, and any correspondence concerning a proposed informal extension. These details help uncover deadlines, restrictive clauses and commercial issues that could change the advice.
Accuracy early on is not about creating more paperwork. It helps prevent the frustrating situation where a quote has to be revised because the lease term, ground rent review or ownership history was misunderstood.
Choose the quote that gives you a workable route forward
Once you have comparable figures and scope, consider the wider commercial position. If your lease is approaching 80 years, delaying to save a modest amount on fees may cost considerably more in premium later. If you are selling or refinancing, you may need a provider that can work to a defined timetable. If you are a landlord managing multiple requests, consistency and auditability may matter more than shaving a small amount off an individual case.
The best quote is the one that gives you clear assumptions, transparent costs, qualified support and a process you can understand. A lease extension should not feel like an open-ended legal problem. With the right information and the right team, it becomes a controlled property decision with a clear next step.
