Introduction

Unexpected costs may arise from a Passive Fire Protection London survey if defects are found and remedial work is urgently required. To ensure that the costs of the various types of buildings and fire protection needs are planned for appropriately, it is important to know what these costs may be.

Did you know? GOV.UK states that employers, landlords, building owners, occupiers and facilities managers can all have fire safety responsibilities for non-domestic premises and must undertake fire risk assessments and provide adequate fire safety measures.

It is the cost of the work that often drives the decisions a manager makes. This article looks at the major costs associated with the work, the different types of services and how to obtain the most transparent quotation for a building.

What Are Passive Fire Protection Services?

Passive fire protection refers to the fire-resistant parts of a building that help contain fire and smoke and slow their spread. Unlike alarms, which warn people about a fire, these systems form part of the building itself.

Common passive fire protection services include:

• Firestopping: Sealing openings around pipes, cables, and other building services.
• Fire doors: Installing, inspecting, or repairing doors designed to resist fire and smoke.
• Cavity barriers: Restricting fire spread through concealed spaces in walls, floors, and roofs.
• Structural steel protection: Applying suitable coatings or other systems to protect steelwork from heat.
• Passive fire protection surveys: Inspecting existing systems and recording defects that need attention.

For a more detailed explanation of these systems, read our guide to passive fire protection and its role in building safety.

The services required will depend on the building’s design, existing fire protection measures, condition and fire safety requirements. Some properties may need isolated repairs, while others may require a coordinated programme of remedial work.

How Much Do Passive Fire Protection Services Cost in London?

There is no single price that applies to every building. The cost of passive fire protection London projects depends on the amount of work, the materials required, site access, and the condition of existing systems.

Here is a practical guide to what affects the price of each service.

These are cost factors, not fixed price estimates. Ask contractors for current rates or a project-specific quotation rather than relying on a general online figure.

For example, sealing a few accessible cable openings in an office may require far less work than repairing multiple breaches across several floors of an occupied building. Both jobs involve firestopping, but their labour and access requirements can differ considerably.

A survey can help establish the scope of the work before you commit to a larger project. CA Fire Protection provides passive fire protection surveys for commercial buildings to help identify defects and determine where further attention may be required.

Ask whether the survey is chargeable, what areas it covers and whether the quotation includes any subsequent remedial work. Do not assume that inspection, reporting and repairs are automatically included in one price.

What Affects the Final Cost?

When comparing passive fire protection contractors, look beyond the number on the quotation. The amount of work required and the conditions on site can make a major difference.

1. Building size and condition

A larger building may require more fire doors, service openings, and compartment walls to inspect. Older buildings may have a number of defects from past maintenance and alteration work.

2. Materials and fire resistance requirements

Different areas of the building may have different requirements for fire protection. This may also affect the cost of the work.

3. Labour and site access

Work in ceiling voids, confined spaces and occupied premises may increase the time required for the preparation of the quotation. Access equipment, working hours, and co-ordination with other trades may increase the cost.

4. Survey findings and remedial work

A survey may identify missing seals on fire doors, damaged fire doors, fire-resistant wall and floor gaps and other fire protection deficiencies. The cost of works will depend on the number of deficiencies and the extent of the remedial works.

Practical tip: Ask your contractor to explain which defects require immediate attention, what work they recommend, and why. This helps you understand where your budget will go.

How Can You Budget for Remedial Work?

A clear process helps you avoid unexpected costs and makes it easier to compare passive fire protection companies.

Follow these four steps:

1. Review your existing reports: Gather fire risk assessments, survey reports, drawings, and records of previous repairs.
2. Determine the work required: List the affected areas and known defects, and the services required. Ask for further inspection if the available documentation is not sufficient.
3. Request an itemised quotation: Check what is included (labour, materials, access equipment, surveys, VAT, exclusions)
4. Plan for follow-up checks: Allow for completion records, quality checks, and future maintenance where required.

For example, if a survey identifies several damaged fire doors and unsealed pipe openings, ask the contractor to list each type of work separately. You can then see which repairs account for the main costs and plan the work in stages where appropriate.

How Do You Choose the Right Contractor?

Price matters, but fire protection work must also meet the requirements of the building.

Before appointing a contractor, check the following:

• Relevant experience: Have they worked on buildings similar to yours?
• Qualifications and Certification: Can they provide evidence of training, insurance and relevant third-party certification?
• Quotes: Are the quotes clear, and do they include the work to be carried out and exclude (if applicable) the products to be used?
• Installation records: Will they provide suitable photographs, product information, and completion documents?
• Aftercare: Can they help with repairs or further work identified during the survey?

GOV.UK guidance explains that fire doors must remain in good working order and that repairs or replacement, where needed, should be undertaken by a competent person.

The same principle applies when choosing contractors for other passive fire protection work: confirm that the proposed system and installation method are suitable for the building.

CA Fire Protection provides surveys and remedial services, including firestopping, fire door work, cavity barriers, and structural steel protection. You can discuss your building’s requirements with the team before requesting a quotation.

Plan Your Fire Protection Budget With Confidence

The cost of passive fire protection in London depends on the building, the services required, and the condition of existing systems. Understanding these factors helps you plan the work, compare quotations, and make informed decisions without compromising fire safety.

Start by reviewing your existing reports and listing the areas that need attention. Then request an itemised quotation from a competent contractor who can explain the proposed work clearly.
