Making a few upgrades to a flat or maisonette often seems simple at first. A new kitchen feels routine. Updated wiring sounds straightforward. Better flooring? That usually feels like a normal part of owning a home. But leasehold properties in England and Wales add another layer. And, honestly, many owners only realise this when they start planning work.
Unlike freehold houses, where owners usually have much more freedom, flats and maisonettes are governed by leases. These documents do more than define ownership. They also set out what changes are allowed. In practice, that can mean getting formal approval before carrying out work. Even relatively minor improvements may need permission, which catches some owners off guard.
Leasehold Ownership And The Limits Of Control
When you buy a leasehold flat, you are not purchasing the building itself. Instead, you buy the right to occupy and use the property for a set period. The freeholder still owns the building structure and shared areas. The lease acts as a legal agreement. It explains how the property can be used and what restrictions apply.
Most leases contain clauses about alterations. These usually require written consent from the freeholder or managing agent. There is a reason for this. The rules help protect the building’s structure. They also help ensure that one leaseholder’s changes do not create problems for neighbours or other residents.
In many situations, this is more than a simple courtesy. It is a legal requirement. Carrying out work without approval can create complications later. You could face enforcement action. Selling the property may become harder. In some cases, obtaining retrospective consent can also be expensive and frustrating.
What Counts As An “Alteration”?
One of the biggest sources of confusion is the term “alteration.” Many homeowners assume it only refers to major structural work. In reality, the definition is often much broader. Removing walls is usually considered an alteration. Changing layouts also falls into that category. Extending living space clearly does too.
Oddly enough, some leases go much further. Electrical rewiring may count as an alteration. Upgrading consumer units might also require approval. This is particularly common during kitchen and bathroom renovation projects. Plumbing modifications can be included too. The same can apply to installing hard flooring or replacing windows and external doors. It really depends on the wording of the lease.
Because lease terms vary so much, checking the lease should always be the first step. It can save a great deal of time later. In many cases, landlords will request a formal licence to alter. This document sets out the approved work. It also explains any conditions that must be followed. Details about how the work should be carried out are usually included as well.
The Importance Of Consent Before Starting Work
One key principle of leasehold ownership is simple. Permission should be obtained before work starts. That part is important. Retrospective approval is sometimes possible. However, it is never guaranteed. Landlords have discretion when considering such requests.
Landlords can also impose reasonable conditions. They may require inspections. Professional oversight might be necessary. Legal or surveyor fees are often recoverable too. While this can feel inconvenient, it is usually part of the approval process.
Ignoring the process can lead to serious complications. This can even affect certain property insurance considerations. Even high-quality work can become an issue. The problem is the missing approval, not the workmanship. Mortgage lenders may raise concerns. Future buyers often do the same. Solicitors typically ask for proof that all alterations received proper authorisation.
Managing Contractors And Ensuring Compliance
Choosing the right contractor matters. In fact, it is one of the most effective ways to reduce risk. Poor workmanship can create problems quickly. Non-compliant installations can be even more troublesome. Freeholders are unlikely to overlook issues involving safety or building regulations.
For example, electrical or roofing work around a flat should be handled by certified electricians in London. They should understand current regulations. Just as importantly, they should understand leasehold requirements. That extra knowledge can prevent headaches later.
Planning Permission Versus Lease Permission
Many people assume planning permission and leasehold consent are the same thing. They’re not. They are completely separate requirements. Planning permission comes from the local authority. It deals with matters such as external appearance, structural changes and planning policies.
Leasehold consent works differently. It is based on the lease agreement itself. That means you can receive planning approval and still breach your lease. It sounds surprising, but it happens. If landlord consent has not been obtained, problems can arise despite having planning permission in place.
Depending on the type of project, both approvals may be required. Skipping either one can create unnecessary complications.

Disputes And Unreasonable Refusal Of Consent
Sometimes, leaseholders face delays when requesting consent. In other cases, the request may be refused altogether. That can be frustrating, especially when the proposed work seems reasonable. Still, the wording of the lease matters.
If the lease states that consent cannot be “unreasonably withheld,” landlords are expected to act fairly. They should provide genuine reasons for refusing a request. Simply saying no is generally not enough.
Where disputes arise, they can be referred to the First-tier Tribunal (Property Chamber). The tribunal can decide whether a refusal was reasonable. However, the process can take time. It may also involve additional costs. For that reason alone, clear communication and thorough documentation are usually worth the effort from the very beginning.
