Renovating Under a Lease: What You Need to Know First

Before any renovation begins, understanding your lease agreement is critical. In London, most flats are leasehold properties, meaning you don’t fully own the structure—only the interior. This legal nuance affects what you can and cannot modify.

Key point: Many lease agreements include restrictions on structural changes, plumbing/electrical work, and even flooring updates. ND Construction can help you review these clauses and plan compliant upgrades.

Step 1: Get Written Consent from the Freeholder

Flat renovations typically require written permission from the landlord or freeholder. This process is often called a “Licence to Alter.”

What we recommend:

• Share your design intentions clearly
• Include drawings and plans
• Highlight that ND Construction follows building codes and uses insured professionals

Getting this consent upfront avoids disputes and protects your investment.

Step 2: Focus on Non-Structural Enhancements

If your lease limits major works, focus on updates that don’t affect the structure—but still have visual and functional impact.

Examples:

• Built-in storage and bespoke wardrobes
• High-end kitchen and bathroom finishes
• New flooring (subject to acoustic underlay approval)
• Smart lighting and home automation

These improvements can elevate your living space without triggering lease violations.

Step 3: Work with Renovation Experts Familiar with Leasehold Properties

ND Construction specialises in London renovations and understands how to work within legal and design constraints.

We offer:

• Consultation with lease and planning advisors
• Interior transformations using non-invasive techniques
• Close collaboration with managing agents and landlords

This ensures a smooth process and peace of mind.

Step 4: Plan for Noise, Timing, and Access

Many London flats are part of shared buildings with neighbours above, below, or adjacent.

What to consider:

• Inform neighbours and managing agents before starting
• Work only during approved hours (usually 8 AM – 6 PM)
• ND Construction handles access logistics and materials transport

Being proactive avoids complaints and keeps projects on schedule.
