I’ve discovered that most leaseholders overpay by thousands when extending their lease simply because they don’t know about informal extensions. While the statutory route can cost £15,000-£30,000 in premiums, legal fees, and tribunal costs, I’ve seen savvy property owners negotiate directly with their freeholders for half that amount. The process takes weeks instead of years, and you’ll avoid the rigid valuation formulas that often inflate your costs. But there’s a critical timing element that determines whether this strategy will work for you.
Key Takeaways
- Informal lease extensions can save around £1,850 in upfront legal costs compared to statutory Section 42 procedures.
- Direct negotiation with freeholders allows flexible terms like 999-year extensions and customizable premium amounts.
- The process completes in 3-6 months versus 12-18 months for statutory routes, avoiding mandatory response periods.
- Bypassing tribunal fees and valuation disputes reduces costs while maintaining good freeholder relationships for future dealings.
- Commission an RICS surveyor for independent valuation before making direct contact to ensure fair market pricing.
What Is an Informal Lease Extension?

An informal lease extension offers a direct negotiation pathway between you and your landlord, completely sidestepping the statutory procedures outlined in the Leasehold Reform Act. Unlike the formal route, you won’t need to serve a Section 42 Notice or meet strict eligibility criteria like the two-year ownership requirement.
I’ve seen leaseholders save markedly on upfront legal costs by choosing this approach. You’ll negotiate terms privately with your freeholder, including lease length and premium amounts. The ground rent typically remains at current rates until your existing lease expires, which differs from the formal route’s peppercorn rent benefit.
This flexibility means you can customize agreements to suit your specific circumstances, making it particularly valuable for those who don’t qualify for statutory extensions or need faster solutions. The entire process can be completed in a couple of weeks if both parties agree promptly on the terms.
How Much Money Can You Actually Save?
When considering informal lease extensions, the immediate savings can be deceptive compared to the long-term financial impact. You’ll save around £1,850 upfront compared to statutory routes, but I need to show you the hidden costs that accumulate over time.
Your ground rent will escalate dramatically – from £250 annually in years 1-10, jumping to £500 in years 11-20, then £1,000 in years 21-24. That’s £13,500 you’ll pay that statutory extensions eliminate entirely. A longer lease can significantly boost property value, making it more attractive to potential buyers and lenders, which is a crucial factor to consider when assessing long-term benefits.
Here’s the real kicker: you’ll need another extension sooner since informal deals typically offer shorter terms. This future extension could cost £78,500 including fees. Your total long-term cost becomes £103,600 versus £13,250 for statutory extensions – meaning you’ll actually lose £90,350 over time.
Once you sign an informal lease extension, the unfavorable terms become permanent fixtures that cannot be altered or removed, leaving you trapped in a cycle of escalating costs that will follow your property forever.
Why Informal Extensions Beat Statutory Routes

Despite the long-term costs I’ve outlined, informal lease extensions offer compelling advantages that statutory routes simply can’t match. You’ll bypass the mandatory 2-year ownership requirement and expensive Section 42 notice fees (£500-£1,000), making extensions accessible immediately after purchase. I’ve seen clients negotiate ground rent reductions and customize extension lengths beyond the 90-year minimum—flexibility that’s impossible with statutory routes.
The collaborative approach preserves your relationship with the freeholder, often resulting in goodwill concessions that reduce overall costs. You’ll avoid tribunal risks and rigid valuation formulas, particularly beneficial for sub-80 year leases where statutory penalties apply. Most importantly, you can respond quickly to market conditions and bundle extensions with other lease modifications, creating thorough solutions that protect your investment while maintaining control over timing and terms. Additionally, having landlord insurance can provide extra peace of mind against unexpected repair costs that may arise during this process.
Additionally, informal extensions typically involve lower legal fees compared to the formal statutory process, as you avoid the complex procedural requirements and potential dispute resolution costs. The streamlined nature of direct negotiation means reduced administrative burden and faster resolution when both parties are willing to engage constructively.
The Speed Advantage: Weeks Not Years
Beyond these strategic advantages, the most compelling reason I recommend informal extensions lies in their remarkable speed advantage. While statutory extensions drag on for 12-18 months, I’ve seen informal deals close in just 3-6 months.
Here’s why you’ll save precious time: You’re bypassing the mandatory two-month freeholder response period, eliminating formal Section 42 notices, and avoiding potential tribunal referrals that can extend timelines indefinitely. The statutory route forces you through rigid bureaucratic steps that can’t be skipped.
With informal negotiations, you’re dealing directly with decision-makers. No waiting for surveyors, no counter-notices, no tribunal delays. When both parties want to move quickly, I’ve witnessed extensions completed in mere weeks. This cooperative approach often strengthens your ongoing relationship with the freeholder, creating goodwill that benefits future property matters. Time is money, and informal extensions deliver both speed and savings that statutory routes simply can’t match.
Negotiation Flexibility That Works in Your Favor

Where statutory extensions lock you into rigid formulas and predetermined outcomes, informal negotiations open up a world of possibilities that can dramatically improve your deal.
I’ve seen leaseholders secure 999-year extensions for zero premium when they’re share of freeholders – something impossible through statutory routes. You’re not confined to the standard 90-year extension either. Want 125 years? 150 years? It’s all negotiable.
The premium flexibility is where you’ll save thousands. Instead of rigid statutory valuations, you can negotiate payment plans, trade higher ground rent for lower premiums, or include non-monetary concessions. I’ve watched clients secure deals that would’ve cost £15,000 statutorily for just £8,000 through creative structuring. Additionally, understanding the hidden costs of leasehold ownership can further enhance your negotiation strategy.
You can also include custom clauses addressing service charges, pet policies, or property alterations – flexibility that puts you in control. Direct negotiation with the freeholder eliminates the formal notice requirements and creates a more collaborative atmosphere for reaching mutually beneficial terms.
Who Can Use This Money-Saving Strategy?
You’re eligible if you haven’t met the 2-year ownership requirement for statutory routes. Recent purchasers and those with business leases or charitable trust properties can bypass formal restrictions entirely. If you’re dealing with mixed-use buildings, disputed titles, or complex ownership structures, informal negotiation becomes your primary option.
The financial benefits are substantial. You’ll avoid costly valuation fees, Section 42 notice costs (£100-£300), and rigid statutory formulas. Short-lease holders facing marriage value premiums often save thousands through direct negotiation. Additionally, the recent Leasehold Reform Act 2025 enhances leaseholder rights, making informal negotiations more favorable.
However, you must accept uncertainty – there’s no guaranteed outcome or statutory protection. Success depends on your freeholder’s cooperation and your negotiation skills. Shared ownership leaseholders must pursue the informal route as their only option for lease extensions.
Building Better Relationships With Your Freeholder

While informal lease extensions lack statutory protection, they offer one decisive advantage: success hinges entirely on your relationship with your freeholder. I’ve seen leaseholders save £15,000+ by building trust through consistent communication and transparency. Notably, solicitor fees can add significant costs to the process, so nurturing a good relationship can also help in negotiating terms that may reduce these expenses.
Start by establishing clear channels for discussions about your extension plans. Respond promptly to their inquiries and demonstrate you’re a reliable tenant who maintains the property well. Document all agreements in writing to create accountability for both parties.
Show flexibility when they raise concerns – accommodate reasonable requests about terms or timing. This isn’t about being pushover; it’s strategic relationship-building that saves money. When your freeholder sees you as a partner rather than an adversary, they’re more likely to offer favorable terms that bypass expensive statutory procedures. Consider regular check-ins to prevent misunderstandings and maintain the positive relationship you’ve worked to build.
When Informal Extensions Make Perfect Sense
Strong freeholder relationships create the foundation, but certain situations make informal extensions the clear strategic choice. I’ve seen leaseholders save thousands when they’re ineligible for statutory routes—perhaps you’ve owned your property under two years or face commercial hybrid restrictions. You’ll bypass costly tribunal fees and mandatory valuation disputes that drain your budget. Additionally, it’s crucial to stay informed about planning permissions to avoid any unexpected legal complications during the extension process.
When you’re racing against property sale deadlines, informal extensions deliver results in 3-6 months versus years of statutory procedures. I particularly recommend this route when your lease approaches dangerous territory where marriage value calculations kick in, potentially doubling your costs.
You’ll also appreciate the flexibility—negotiate terms beyond standard 90-year extensions, customize ground rent arrangements, and structure payments to match your financial situation. The direct negotiation approach allows you to potentially secure a lower initial premium compared to the rigid statutory framework. It’s strategic thinking that puts money back in your pocket.
Potential Drawbacks You Need to Consider

Although informal extensions offer compelling advantages, they expose you to significant risks that could cost you substantially more than statutory routes. Without statutory safeguards, you’re at your freeholder’s mercy regarding terms and pricing. I’ve seen leaseholders accept shorter extensions under 90 years, missing vital marriage value protection that’ll cost them dearly later. Additionally, this lack of protection can lead to complications in decision-making that further complicate the ownership experience.
Ground rent escalations frequently creep into informal agreements, creating perpetual financial burdens. Your freeholder can inflate premiums above statutory rates since there’s no standardized valuation methodology protecting you. Additionally, freeholders often include administrative fees that further increase your overall costs beyond the actual premium. If disputes arise, you’ll face costly litigation without predefined resolution mechanisms.
The power imbalance heavily favors freeholders, who retain unilateral control over essential conditions. You might secure a shorter lease that depreciates faster, requiring another expensive extension sooner than anticipated.
Step-by-Step Guide to Securing Your Deal
Since you’ve weighed the drawbacks against potential benefits, let’s walk through the practical steps to secure an informal lease extension.
First, I’ll commission an RICS surveyor for independent valuation – this upfront investment gives you negotiation leverage and realistic premium expectations. Request separate valuations for both informal and statutory routes to compare costs effectively.
Next, contact your freeholder directly using details from ground rent receipts or Land Registry records. Draft a clear offer letter specifying your desired extension length and proposed premium based on your valuation. It’s important to remember that executor delays can complicate negotiations, so ensuring that all parties are informed can help expedite the process.
During negotiations, remember you’re not bound by statutory timelines, but freeholders aren’t required to justify their demands either. The freeholder retains underlying land ownership throughout the process, which gives them considerable control over the terms they’re willing to accept. Once terms are agreed, instruct a property solicitor to draft the new lease documentation. You’ll cover the premium, legal fees, surveyor costs, and Land Registry fees to complete the transaction.
Conclusion
I’ve shown you how informal lease extensions can slash your costs by thousands while delivering results in weeks, not years. You’ll avoid statutory fees, tribunal costs, and lengthy procedures through direct negotiation. However, don’t ignore the risks—you’re trading legal protections for speed and savings. Calculate your numbers carefully, assess your freeholder’s reasonableness, and get proper legal advice before proceeding. The potential savings make this route worth serious consideration for suitable cases.
