In an ongoing effort to improve fire safety across London, especially in older residential properties, local councils and safety regulators have made fire-resistant door enhancements a top priority. A key component of this initiative is the mandatory installation of fire door strips—commonly known as intumescent strips or smoke seals—on entrance and communal doors. At Fix in London, we provide expert door fitting with strip services tailored to meet these evolving safety requirements, helping property owners ensure compliance and protect lives.
London councils now require fire-resistant door strips on entrance and communal doors to boost fire safety, especially in older homes. Fix in London offers expert installation services to help property owners comply with new regulations and safeguard residents. Listen to this podcast:
What Are Intumescent Door Strips and Why Are They Important?
Intumescent strips are a vital safety feature installed around the perimeter of fire-rated doors. In the event of a fire, these strips expand when exposed to high temperatures, effectively sealing the door’s edges to prevent the spread of smoke and flames. By slowing the progression of fire through hallways and exits, these strips can offer a critical time window for residents to escape safely.
Depending on the building’s fire risk assessment, doors fitted with these strips are typically rated to resist fire for 30 or 60 minutes, providing essential protection in high-risk scenarios.

Why Have Fire Door Strips Become Mandatory in London?
Following guidance from fire safety inspectors and local housing authorities, many residential blocks across London—particularly those built before modern fire regulations—are now required to upgrade their fire protection systems. This includes retrofitting flat entrance doors and communal doors with compliant fire doors and properly installed intumescent strips.
This legal shift comes in response to increased scrutiny over building fire safety and aims to reduce the risk to residents in the event of an emergency. Compliance is not just a formality; it’s a potentially life-saving measure that all responsible landlords, property managers, and homeowners should take seriously.

The Door Strip Installation Process
Installing fire-rated door strips isn’t a basic DIY job—it’s a technical process that must align with British Standards (BS 476) and the UK Building Regulations (Approved Document B). Our professional fitting service includes:
Thorough Assessment: Evaluating the existing door to determine if it’s suitable for upgrades or requires full replacement.
Precision Installation: Carefully fitting intumescent and/or smoke seals into the door edge or frame.
Functional Testing: Ensuring proper alignment, airtight seal, and unhindered operation of latches, hinges, and door closers.
Full Compliance Check: Verifying that the finished installation meets all legal and safety standards.
Improper installation can compromise a door’s fire resistance entirely. That’s why Fix in London only uses qualified fire door specialists for every job.

Who Is Responsible for Installing Fire Door Strips in London?
One of the most common questions surrounding fire door strip regulations is responsibility. In most London properties, responsibility depends on ownership and building type:
Landlords are responsible for ensuring flat entrance doors meet fire safety regulations
Freeholders or managing agents are responsible for communal doors
Homeowners are responsible if they own the property outright
Leaseholders may be responsible depending on lease agreements
Failure to comply can lead to enforcement notices, fines, and legal action by local councils or fire authorities.
What Happens If Fire Door Strips Are Not Installed?
Non-compliance with fire safety regulations can have serious consequences, including:
Council enforcement notices
Financial penalties or fines
Invalidated building insurance
Increased legal liability in case of fire
Risk to life and property
Installing compliant fire door strips is not just about meeting regulations—it’s about preventing avoidable tragedies.
Types of Fire Door Strips Used in London Properties
Different buildings require different fire door strip configurations. Common types include:
Intumescent-only strips – expand under heat to block flames
Intumescent strips with smoke seals – block both smoke and fire
Surface-mounted strips – used when door edges cannot be rebated
Rebated (concealed) strips – fitted into the door or frame for a cleaner finish
Our specialists assess each door individually to determine the correct strip type based on fire risk and compliance requirements.

Fire Door Strip Installation for Older London Properties
Many Victorian and post-war buildings in London were not originally designed with modern fire safety standards in mind. Retrofitting fire door strips is one of the most effective ways to upgrade safety without major structural changes.
Professional assessment is essential to determine:
Whether the existing door can be upgraded
If a full fire door replacement is required
The correct fire resistance rating

Frequently Asked Questions
- What kind of strips are required for fire doors?
We use intumescent strips and smoke seals, which expand under heat to block fire and smoke from spreading.
- Do all London flats need door strips now?
Most councils have made this a requirement for older buildings. It’s best to check with your local authority or fire officer for specifics.

While technically possible, we highly advise against DIY installations. Incorrect fitting can invalidate the door’s fire rating and put lives at risk.
- How long does it take to fit a door strip?
Generally, installation takes about 1 to 2 hours per door, depending on the door’s current state and complexity.
