If your landlord has said, “We can sort this out informally,” it can sound like the easiest route available. An informal lease extension negotiation may well be quicker than a statutory claim, and sometimes it does produce a sensible outcome. But speed on its own is not the same as value, and a friendly offer is not always a good one.
For leaseholders, the real question is whether the deal improves your position without storing up future cost. For landlords, the question is slightly different – can you agree terms efficiently, keep administration under control and avoid unnecessary dispute? In both cases, the answer depends on the detail of the lease, the premium, the ground rent terms and how the negotiation is handled from the start.
What informal lease extension negotiation actually means
An informal lease extension negotiation is a deal agreed directly between leaseholder and landlord outside the formal statutory process. Instead of serving a legal notice and following a prescribed timetable, the parties discuss terms and try to reach agreement privately.
That can make the process feel simpler. There is often more flexibility over timing, and in some cases the legal work can be more straightforward. Landlords may prefer it because they can control the commercial terms more freely. Leaseholders may prefer it because it can appear less confrontational and, at first glance, less expensive.
The key point is that informal does not mean unstructured. It also does not mean safer. If you are not measuring the offer against the statutory position, you are negotiating without a proper benchmark.
Why some informal lease extension negotiations work well
There are situations where an informal route makes practical sense. If both parties are responsive, the premium is fair and the revised lease terms are clean, an agreement can be reached without the stop-start rhythm that often comes with a formal claim.
This can be particularly useful where a leaseholder needs progress quickly for a sale or remortgage, or where a landlord is managing a portfolio and wants a streamlined way to deal with extensions. A negotiated agreement can also allow room for sensible commercial compromises that the statutory route does not always provide.
That said, a faster deal is only better if the final lease is genuinely better. A lower upfront premium can be offset by an ongoing ground rent. A longer term can come with clauses that make the flat less attractive to future buyers or lenders. This is where many informal deals go wrong.
The main risks for leaseholders
The biggest risk in an informal deal is accepting terms that look reasonable in isolation but compare badly with your statutory rights. Under the formal route, qualifying leaseholders generally have a right to add 90 years to the lease and reduce ground rent to a peppercorn. That is a strong benchmark.
In an informal lease extension negotiation, the landlord may offer fewer years, retain ground rent or introduce new rent review clauses. These are not minor drafting points. They affect value, mortgageability and future saleability.
Ground rent is often where the problem sits. A deal that keeps or increases ground rent can leave you with a lease that is harder to sell and less appealing to lenders. Even if the premium looks lower than expected, the long-term cost may be higher.
There is also the issue of control. In a statutory claim, there is a legal framework, set deadlines and a path to tribunal if terms cannot be agreed. Informally, none of that applies unless both parties continue to engage constructively. If the landlord delays, changes the price or adds conditions late in the day, your options narrow unless you are ready to switch to the formal route.
Why landlords may prefer the informal route
From a landlord’s perspective, an informal negotiation can reduce friction. It may avoid procedural disputes, create more freedom over pricing and shorten the path to completion when the leaseholder is motivated.
For freeholders and asset managers, that can be commercially attractive. There is less administrative drag if matters are handled in a coordinated way, and portfolio decisions can be made more consistently. In the right circumstances, an informal agreement can be efficient for both sides.
But landlords also benefit from clarity. A deal that is poorly explained, inconsistently documented or slow to progress can create more work rather than less. A managed process matters here. Efficient lease extension handling is not just about agreeing a number. It is about valuation, engagement, documentation and timing all lining up properly.
How to judge whether the offer is fair
The first step is simple: compare the informal offer to the statutory alternative. If you qualify for a formal lease extension, you need to know what that route is likely to deliver in terms of premium, term and ground rent outcome.
Without that comparison, you are guessing. A landlord’s opening figure may be fair, ambitious or entirely tactical. The same applies to their draft terms. A proper valuation gives you an anchor, and a review of the lease wording tells you whether the offer contains hidden cost.
Look closely at four areas: the premium, the length of the new term, the treatment of ground rent and any wider changes to lease clauses. If the landlord is asking for a modernised lease, that may be reasonable. If the updated drafting shifts costs, tightens restrictions or preserves an income stream that would disappear under the statutory route, the deal needs closer scrutiny.
Informal vs statutory – the trade-off is real
There is no universal winner here. Informal can be quicker and sometimes cheaper on transaction costs. Statutory can be slower, but it gives leaseholders legal protection and a defined outcome if they qualify.
That trade-off matters most when the lease is getting shorter. Once lease length drops, the cost pressure increases and the margin for error gets smaller. If you are close to a sale, trying to refinance or concerned about future value, certainty may matter more than convenience.
For landlords, the balance is slightly different. An informal route can support better administration and quicker completions, but only if the process remains commercially sensible and compliant with an evolving legal landscape. The Leasehold and Freehold Reform Act 2024 has changed the wider context. Even where implementation details continue to develop, both leaseholders and landlords are right to think carefully about timing, entitlement and future practice rather than relying on old assumptions.
A sensible way to handle informal lease extension negotiation
The strongest informal negotiations tend to have one thing in common: both sides know what the formal benchmark is before they start making concessions. That keeps the discussion grounded.
For leaseholders, that means understanding your eligibility, your likely premium and the value of a peppercorn ground rent under the statutory route. For landlords, it means approaching the matter as an asset management exercise rather than an ad hoc conversation that drifts for months.
It also helps to treat heads of terms seriously. If broad agreement is reached, record the key points clearly before legal drafting begins. That reduces the risk of later disagreement over rent, term, costs or new clauses.
If the negotiation starts to wobble, it is worth deciding early whether to continue informally or move to the formal route. Waiting too long can cost time and bargaining power, especially where a leaseholder is working against a transaction deadline.
This is exactly why many parties now prefer specialist handling rather than trying to coordinate surveyors, solicitors and landlord engagement separately. A managed process tends to produce better decisions because the valuation, legal and practical points are looked at together, not in isolation.
When to be especially cautious
You should be careful if the landlord offers a small extension rather than a full one, insists on continuing ground rent, avoids committing to terms in writing or pressures you to proceed without valuation advice. None of those points automatically makes the deal wrong. They do mean you should slow down and test the numbers properly.
Equally, if you are a landlord dealing with multiple flats, caution is needed where negotiations are being handled inconsistently across the portfolio. What looks flexible in one case can become inefficient very quickly if each matter follows a different path.
A good agreement is not just one that completes. It is one that stands up commercially later, whether that means a leaseholder can sell without difficulty or a landlord can administer the asset without unnecessary complication.
Informal lease extension negotiation can be a useful route, but only when it is measured against the alternative and handled with discipline. If the terms are fair, the drafting is clean and both sides stay focused on the long-term outcome, it can save time and reduce hassle. If not, the apparent shortcut can become the expensive option. The best next step is usually the simplest one – find out where you stand before you agree anything.
