If you own a leasehold property in London and are planning building works, you may have been told that you need a Licence to Alter before your project begins. For many leaseholders, this requirement can feel confusing or unnecessary, particularly when planning internal changes or renovations that don’t appear to affect anyone else.
However, failing to obtain the correct licence can quickly lead to serious problems, from delays and legal disputes to difficulties selling or remortgaging your property in the future. Understanding what a Licence to Alter is, when it’s required, and how to approach the process correctly is key before any work begins.
At The Party Wall Guru, we have years of expertise in License to Alter. We’re able to provide practical advice and manage everything, removing any unnecessary stress or uncertainty from the process. In this article, we’ll explain what a Licence to Alter is, and help you determine if you might need one ahead of your next project.
Licence to Alter: Explained
A Licence to Alter is a formal legal document issued by a freeholder that grants permission for a leaseholder to carry out alterations to their property. It is most commonly required in leasehold flats, but may also apply to leasehold houses.
The licence exists to protect the freeholder’s interest in the building and ensure that any alterations are carried out both correctly and in accordance with the lease. It also protects other residents by ensuring works do not compromise the structure, services or shared areas of the property.
In London, where many buildings are converted, listed, or structurally complex, Licence to Alter applications are extremely common and often more detailed than leaseholders expect.
What Types of Work Usually Require a Licence to Alter?
Whether a licence is required depends on the wording of your lease and the nature of the proposed works. In many cases, even just internal work alone may still require consent.
Common examples include removing or altering walls, especially if they’re load-bearing, installing new bathrooms or kitchens that affect plumbing or drainage, replacing flooring with hard surfaces and making changes that affect ventilation, fire safety or sound insulation.
Structural works almost always require a licence, but so do many non-structural alterations if they impact the building fabric or shared services. This is why it’s risky to assume permission isn’t needed, and it’s always wise to seek professional advice first.
Do you Always Need a Licence to Alter?
Not all works require a licence, but the decision should never be based on assumption. Some minor, non-invasive works may be permitted under the lease without formal consent, while others may only require written approval rather than a full licence.
The main point is that the freeholder decides what level of consent is required, not the leaseholder. Carrying out works without approval where a licence is required puts you in breach of your lease, which can have legal consequences.
This is where working with an experienced licensed to alter consultant, such as The Party Wall Guru, becomes invaluable. Our specialists can review your lease, assess your proposals and confirm exactly what level of consent is required before you proceed.
The Licence to Alter Application Process
The Licence to Alter process typically begins with submitting detailed information about the proposed works to the freeholder or managing agent. This usually includes drawings, specifications and sometimes structural calculations or method statements.
The freeholder may instruct their own surveyor and solicitor to review the proposals. It’s important to note that, in most cases, the leaseholder is responsible for covering these professional fees, even though the advisers act on behalf of the freeholder.
Once the works are approved in principle, the licence is drafted as a legal document setting out the conditions under which the works can proceed. These conditions may include requirements for contractors, working hours, insurance and reinstatement obligations.
Only once the licence is completed and executed should the works begin.
Can you Proceed Without a Licence?
Carrying out works without a required Licence to Alter can lead to several problems. Freeholders can require unauthorised works to be removed or reinstated, even years later. You may also face legal action or enforcement costs.
Perhaps most commonly, issues arise when selling or remortgaging a property. Solicitors routinely request evidence of licences for past alterations, and missing documentation can delay or jeopardise a transaction entirely.
Obtaining a licence retrospectively is often more expensive, more time-consuming and far more stressful than dealing with it as it should be at the outset.
