At Oakfield Chartered Surveyors, our mission is simple: to offer personalised, high quality surveying and valuation services that exceed your expectations. We understand that every property and client is unique, which is why we take the time to listen, understand your specific requirements, and provide expert advice that you can trust. As Chartered Building Surveyors, we regularly guide clients through the early stages of extending a lease. Here is how to get started with clarity and confidence.

Why extending your lease matters
Check where you stand
Before you do anything else, establish the key facts. Confirm the exact unexpired term of your lease and review any ground rent provisions, especially if the rent escalates over time. Lenders and buyers pay close attention to these details. It is also worth checking whether you qualify for a statutory lease extension route, which usually requires that you have owned the property for at least two years. If you do not yet qualify, you might explore alternatives such as the seller serving notice before completion and assigning the benefit to you, or a negotiated informal extension with the freeholder.
Statutory or informal – choosing your route
You generally have two routes to extend your lease. The statutory route gives you specific legal rights and protections, including a predictable framework for valuation, timescales, and dispute resolution. It typically adds years to your lease and in many cases reduces ground rent to a peppercorn. The informal route involves negotiating directly with the freeholder outside the statutory process. While this can be faster and more flexible, it may come with terms that are less favourable, such as a shorter top up of years or changes to ground rent and covenants. You should compare both options carefully with professional advice so that you understand the long term impact before you decide.
Get the right team in place
A successful lease extension is a blend of sound valuation, careful legal work, and pragmatic negotiation. You will benefit from appointing a Chartered Surveyor experienced in lease extensions to advise on value and strategy, and a solicitor who specialises in leasehold law to manage notices, timelines, and the drafting of the new lease. At Oakfield Chartered Surveyors, we work closely with your solicitor to keep the process coordinated and on track.
A typical early stage plan might include:
- An initial review of your lease, ground rent, and unexpired term, with a short note on risk and urgency.
- A valuation to estimate a reasonable premium range and to inform your negotiation stance.
- Clear advice on statutory and informal options, including likely timescales, third party fees, and potential negotiation points.
Understanding the valuation
The premium you pay to extend your lease reflects several factors, including the current lease length, ground rent terms, the property’s value, and whether the remaining term has crossed the 80 year threshold. If the lease is short, the premium can be materially higher. As your surveyor, we will provide a valuation range supported by market evidence and explain the key drivers so you know what is negotiable and what is not.
Managing costs and expectations
In addition to the premium, you should budget for your own professional fees and, in most statutory cases, the reasonable legal and valuation costs of the freeholder. There may also be fees for the new lease deed, any mortgagee consent, and Land Registry registration. Good preparation helps you avoid surprises. We will set out a realistic budget envelope and highlight where decisions you make, such as route selection or offer strategy, could influence total cost.
Common pitfalls to avoid with Lease Extensions
Do not wait until the lease is very short, as costs rise and financing options can shrink. Do not rely on headline offers without understanding changes to ground rent or covenants that could affect future value or saleability. Avoid proceeding without a clear timeline, as delays can add cost and reduce leverage. Most importantly, do not skip the valuation stage; a robust valuation underpins a successful negotiation.
How can Oakfield Chartered Surveyors help?

Frequently Asked Questions about Extending a Lease
When should I start the lease extension process?
If your lease is approaching 85 to 90 years unexpired, it is sensible to start planning. Once the term falls below 80 years, the premium usually increases because marriage value may become payable, and mortgage options can narrow. Starting earlier protects value and gives you more flexibility over timing and costs.
Is it better to extend my lease through the statutory route or negotiate informally?
The statutory route provides a clear legal framework, predictable timelines, and typically reduces ground rent to a peppercorn, which many lenders prefer. An informal extension with the freeholder can sometimes be quicker or allow bespoke terms, but it may come with less favourable conditions, such as higher ground rent or fewer years added. We will compare both options for you so that you can choose the route that best fits your aims and budget.
What costs should I budget for beyond the premium?
In addition to the premium, you should allow for your own surveyor and solicitor fees and, in most statutory cases, the reasonable legal and valuation costs of the freeholder. There may also be charges for the new lease deed, lender consent if you have a mortgage, Land Registry fees, and any managing agent administration. We will provide a clear budget outline at the outset so that you know what to expect.
