Our Guide to Structural Steel Fire Protection
Professional fire door installation is a vital part of protecting life, limiting fire spread, and helping buildings remain compliant with fire safety legislation. In commercial settings, fire doors are not standalone products. They form part of a wider compartmentation strategy that helps contain fire and smoke and protects escape routes.
At Fire Industry Specialists (FIS), we provide a fully compliant fire door installation service for commercial properties across the UK. Whether the requirement is for a single fire rated door or a programme of fire doors across a large site, our team delivers installations built around performance, precision, and compliance.
What does fire door installation involve?
A compliant fire door installation is about far more than fitting a new door leaf into an existing opening. Every element of the door set must work together to achieve the required fire resistance.
The complete door set matters
A fire door installation typically includes:
- the fire door leaf
- the frame or lining
- intumescent and smoke seals
- hinges, locks, and closers
- glazing systems where required
- threshold details and gaps around the door
Each of these components contributes to the door’s overall performance. Even where the door itself is certified, poor installation can mean it will not perform as intended in a fire.
Installing a fire rated door correctly
When installing a fire rated door, tolerances, frame alignment, seal placement, and hardware compatibility all need to be considered carefully. This is why our installation of fire doors always follows the manufacturer’s instructions as well as relevant guidance such as BS 8214, BS 476-22, and BS EN 1634-1.
At FIS, our process begins with assessing the opening and specification requirements, followed by the installation of a fully compatible door set and final checks to ensure compliance and functionality.
Types of fire door installation we provide
Internal fire rated doors
Internal compartmentation is one of the most common reasons for fire rated doors installation.
These doors are used in corridors, stairwells, plant rooms, risers, and other areas where the building layout relies on fire-resistant separation.
Fire exit doors
We also provide fire exit door installation for buildings that need compliant escape routes and emergency exits.
These doors are commonly used in commercial, industrial, and mixed-use buildings where safe egress is a legal and practical requirement.
HMO fire doors
Although this page is focused mainly on commercial clients, we also undertake residential fire door installation in HMOs and multi-occupancy settings.
In these buildings, fire doors play an important role in protecting communal areas and escape routes.
Full fire door programmes
For larger projects, our team can manage full programmes of fire door installations across multiple floors, departments, or buildings.
This is particularly useful for offices, schools, healthcare settings, apartment blocks, and large refurbishments where consistency and documentation are essential.
Fire door compliance
Once the correct door type has been selected, the next priority is ensuring the installation aligns with wider compliance requirements. This is particularly important in commercial projects, where fire door performance must support both the building design and the legal duties of those managing it.
Key standards and guidance
Our work is carried out in line with the standards and guidance relevant to fire door installation UK projects, including:
- Approved Document B, which sets out fire safety expectations for building design
- BS 8214, which provides guidance on the installation of fire door assemblies
- BS 476-22, which covers fire resistance testing of non-loadbearing elements
- BS EN 1634-1, which relates to fire resistance testing for doors and shutters
Installation as part of a wider compliance strategy
A successful commercial fire door installation project should not be viewed in isolation. It often sits alongside surveys, remedial works, handover documentation, maintenance planning, and wider passive fire protection measures. Our role is to help clients make sure each installation supports the building’s overall fire safety strategy.
What affects the cost of a fire door installation?
The cost of a fire door installation can vary significantly depending on the building, the specification, and the scale of the work involved. For that reason, it is usually best assessed on a project-by-project basis.
Factors that affect project scope
The main factors that influence fire door installation cost include:
- the number of doors being installed
- the fire rating required, such as FD30 or FD60
- whether glazing is included
- the condition of the opening and frame
- any joinery or remedial works needed before installation
- access constraints or live-site working requirements
- whether the work forms part of a larger compliance programme
Why a survey is important
A site assessment allows us to understand exactly what the project involves before pricing it. This is particularly important on refurbishment or replacement works, where hidden issues with frames, openings, or existing doors may affect the scope.
For clients comparing fire door installation companies, a detailed survey also helps ensure quotations are based on like-for-like requirements rather than assumptions.

Fire Door Installation FAQs
- Why is it important to use certified fire door installers rather than general carpenters?
- The correct installation of fire doors is a life safety matter. If a fire door is installed incorrectly, it will not perform as designed and could allow fire and smoke to spread rapidly. A certified fire door installer has the training and accreditation to ensure the door is fitted to the exact standards required. At FIS, all of our fire door installers are third-party certified, providing assurance that your fire doors installation is fully compliant with British Standards and fire safety legislation. Choosing uncertified installers risks invalidating certification and leaving your building non-compliant. For complete peace of mind, trust FIS’s certified fire door installers to carry out the work. Contact us today to arrange your fire door installation.
- What does the fire door installation process involve?
- Every installation begins with a professional survey to establish whether an existing door can be retained or whether fire door replacement is required. From there, our team ensures doors are installed correctly, with frame alignment, fire and smoke seals, ironmongery, and closers fitted to specification. FIS follows strict procedures to deliver consistent and compliant results, with every project overseen by a certified fire door installer. Once installed, the doors are fully checked, documented, and handed over with evidence of compliance. If you need fire door installation across the UK, FIS provides a complete service from survey through to certification. Speak to us today about your project.
- Do all buildings need the same type of fire door installation?
- Fire door installation should always reflect the building type, layout, occupancy, and fire strategy. A door set that is suitable for one building may not be appropriate for another, which is why a professional assessment is so important before any installation work begins. At FIS, we work with building managers, developers, and property teams to install fire doors that meet the required fire resistance and suit the demands of the building. This helps ensure the right level of protection is in place where it is needed most.
- Can fire doors be installed in occupied buildings?
- Yes, in many cases fire door installation can be carried out in occupied buildings, including commercial premises, education settings, healthcare environments, and residential developments. The approach will depend on the site, the volume of doors being installed, and how access can be managed safely. A planned programme of works helps reduce disruption while still ensuring all fire doors are fitted correctly and compliantly. If you need fire doors installing in a live environment, we can advise on the best way to approach the project.
- Will I receive documentation after installation?
- When we complete a fire door installation, we provide the relevant documentation to confirm the work has been carried out in line with the required standards. This gives you a clear record of what has been installed and supports your wider fire safety responsibilities as a building owner, manager, or responsible person. Our team works to ensure every installation is properly checked, compliant, and backed up with the appropriate information for your records.
- How long does fire door installation take?
- The timescale for fire door installation depends on the number of doors involved, the type of building, the condition of the existing openings, and whether replacement or remedial works are needed first. A single installation may be straightforward, while larger projects across multiple doors or occupied sites will need a more structured programme. The best way to get an accurate timescale is to arrange a survey so the scope of the work can be properly assessed.
- Are fire doors only required in commercial buildings?
- Fire doors are used across a wide range of settings wherever compartmentation and protected escape routes are needed. That includes commercial premises, multi occupancy residential buildings, education settings, healthcare buildings, hotels, and other regulated environments. Fire door requirements will depend on the building’s use and fire risk assessment, but the aim is always the same: to help slow the spread of fire and smoke and protect escape routes.
- Do newly installed fire doors need ongoing maintenance?
- Once a door has been fitted, it should be checked and maintained over time to make sure it remains in good working order. Wear and tear, building movement, damaged seals, and issues with closers or hinges can all affect performance. Regular inspections and maintenance help ensure your fire doors continue to protect the building as intended, which is why ongoing servicing is an important part of long term compliance.
