Understand your building’s fire safety design and the effect of proposed changes
Missing fire safety records can leave an owner unsure how a building is intended to work. A refurbishment can create similar uncertainty when the layout changes but the original strategy is left behind. Spycon Security Ltd prepares fire strategy reports in Leeds to establish the design approach, document key assumptions and identify the evidence needed to support them.
We assess existing properties, conversions, new developments and commercial alterations. Whether you need a retrospective fire strategy or an updated report for proposed works, we define the purpose before the assessment begins.
Straightforward domestic reports start from £750 plus VAT. Send the building address and available records for a scope review.
What is a fire strategy report?
A fire strategy report describes the intended fire safety arrangements of a building and explains how they work together. It covers the design of escape routes and fire separation, the contribution of protective systems, firefighter provisions and the assumptions about occupation and management. The document should make clear which information is established and which still needs verification.
For an existing Leeds property, this can help an owner understand the basis of a protected stair, the intended evacuation approach or the requirements that should govern future tenant alterations. For a new development, it provides a coordinated fire safety brief for the design team.
The strategy may include written assessment, references to the selected guidance and accompanying drawings. It should be identifiable by date and revision and tied to the plans it assesses. This makes it possible to check whether a later refurbishment remains consistent with the original approach or requires the fire strategy to be reviewed.
Which type of fire strategy report do you need?
A request for a “fire strategy” can mean several different things. Establishing the report’s purpose is particularly important when a fire risk assessment has raised a specific design issue. These common descriptions identify stages of work; they are not standard certificate grades, and the assessment method is a separate decision.
Retrospective fire strategy
This examines the arrangements of an existing building using available records and an agreed survey. It can help establish the design basis when the original report is missing. The assessment records what is known, what remains uncertain and which further investigations or improvements are needed to support its conclusions.
Review, update or addendum to an existing report
Where a usable strategy exists, the task may be to assess the effect of a refurbishment, tenancy change or new evidence. The review should identify the original document and drawings, define the changes and explain the resulting requirements. An addendum needs to remain readable alongside the report it modifies.
Feasibility or concept strategy
For a proposed development or conversion, early advice identifies the constraints that shape the layout. In a retained industrial building around Holbeck or Hunslet, the questions may concern the existing structure, stairs and proposed occupancy. The output helps guide design decisions and survey priorities before a detailed solution is commissioned.
Planning-stage fire safety input
If the planning process requests fire safety information, provide the wording of that request. The required document may address matters such as site access and the broad layout at an early stage. A planning Fire Statement, where applicable, has a different scope from the technical strategy needed for a developed design.
Design and construction-stage strategy
The design-stage report explains how the proposed building addresses the selected fire safety basis. Later updates coordinate changes arising from architectural, structural and services development. For occupied refurbishments, temporary construction arrangements need their own assessment; the report for the completed layout does not automatically cover every phase of the works.
As-built or handover strategy
This records the final design using suitable completion evidence and drawings. For an owner managing several buildings, a clear as-built record makes future alterations easier to assess. It should identify the provisions and management assumptions to maintain, with unresolved information visible rather than absorbed into an unqualified statement about the completed property.
Building types covered by the service
Residential enquiries can include houses, extensions, loft conversions, HMOs, converted flats and larger apartment buildings. The brief can address a new proposal or the design assumptions of an existing property. An open-plan domestic alteration may need specific consideration of the stair, escape route and proposed protection.
Commercial work can include offices, shops, hospitality premises, hotels, educational buildings, warehouses and industrial units. For a Leeds property portfolio, the first step is to identify each use and the question to be answered. The technical scope and competence requirements are assessed for the individual premises, including any specialist or mixed-use features.
When the fire risk assessment asks for a strategy
A fire risk assessment may identify a design question it cannot resolve: the intended evacuation approach, the basis of a protected stair, the fire separation between occupancies or the effect of previous alterations.
A fire strategy can examine those questions using the building information and agreed inspection scope. The report explains the design basis and records where evidence is still required. Physical defects, missing tests and management actions may need separate work alongside it.
Send the complete risk assessment and the specific action you need to address. This helps avoid commissioning a broad report when the immediate question needs a targeted investigation, or overlooking a wider design issue because only one action has been supplied.
Retrospective fire strategy reports in Leeds
For an occupied apartment building, office or mixed-use property, we begin by establishing what records are available and how reliably they represent the premises.
- Existing plans and previous fire strategy reports help identify the original assumptions.
- Refurbishment and fit-out records show where the building may have changed.
- Fire risk assessments and inspection reports highlight known issues and unresolved questions.
- An agreed survey helps compare the records with accessible site conditions.
The report distinguishes documented facts, observed conditions and assumptions. Where a concealed floor, shaft or service penetration needs further investigation, that requirement is stated clearly. A desk-based review cannot confirm the condition of features that have not been evidenced.
Refurbishments and tenant fit-outs
For an office alteration in the city centre or a conversion around Holbeck and Hunslet, the key question may be how the new layout interacts with the rest of the building. A moved partition, new tenant boundary or additional occupied floor can affect routes and provisions outside the immediate work area.
We review the proposed layout against the available building strategy, identify interfaces with shared stairs and systems, and set out the fire safety requirements for the design team. For works in an occupied building, tell us how access and occupation will change during the project so temporary arrangements can be scoped separately from the completed design.
Residential enquiries can include house-to-flat conversions, HMOs, extensions and loft conversions in Headingley, Hyde Park and other Leeds neighbourhoods. The assessment follows the actual building and intended use.
What your fire strategy report covers in detail
Building description, design basis and evidence
The report establishes the building use, storeys, relevant dimensions, occupancy and scope of the works. It identifies the plans and other documents reviewed, the assessment method and important assumptions. For an existing property, a distinction is needed between information supported by records, accessible conditions observed during a survey and matters that remain unverified.
Means of escape and evacuation
The assessment considers how occupants reach a place of safety, including travel distances, exit capacity, protected corridors and stairs, final exits and the effect of different uses. The evacuation approach must suit the building and its occupants. A stay-put arrangement, simultaneous evacuation or another approach needs an appropriate design basis; the choice cannot be made from the property label alone.
People who may need assistance must be considered. A refuge can form part of an agreed assisted-evacuation arrangement, but providing a refuge does not by itself explain how someone will reach safety. The strategy should identify relevant design and management responsibilities without assuming that every occupant can use stairs unaided.
Fire resistance, compartmentation and doors
Walls, floors, shafts, doors and fire-stopping work together to restrict fire and smoke spread and protect escape routes. The report identifies the relevant compartment boundaries and performance requirements. Openings for services, junctions and later alterations need coordination so that an intended fire-resisting line is maintained. A drawn compartment boundary does not prove the condition of concealed construction.
Internal and external fire spread
The design considers relevant internal lining performance and external spread issues involving walls, roofs, openings and boundaries. The information needed depends on the proposal and the available evidence. A fire strategy does not automatically include an intrusive external wall appraisal, material testing or a detailed assessment of every façade component; any such work needs an appropriate specialist scope.
Fire protection systems and their interfaces
Detection and alarm, emergency lighting, smoke ventilation and suppression may contribute to the strategy. The report identifies their intended roles and relevant design requirements. Automatic opening vents, door releases, smoke-control equipment and other interfaces need coordinated specialist design. System layouts, calculations, installation, commissioning and maintenance documentation remain separate deliverables unless expressly included.
Firefighter access and facilities
Depending on the building, the assessment addresses appliance approach, access within the premises and relevant firefighting facilities. Risers, hydrants, firefighting shafts and associated provisions need suitable location and design information where applicable. Site constraints should be identified early, including access routes or shared areas controlled by others, so the strategy does not rely on an arrangement the project cannot provide.
Turning incomplete records into an actionable brief
For an existing Leeds building, each conclusion should be connected to the evidence that supports it. If a historic plan shows a compartment floor but its construction is unknown, that remains an investigation issue. If the current fit-out differs from the plan, the assessment must address that difference. This helps the owner distinguish a missing document from a physical defect or a management action requiring separate attention.
Drawings that remain useful after the refurbishment
Where commissioned, the drawing package can mark protected corridors and stairs, exits and travel distances, compartment boundaries and fire door requirements. Other relevant provisions may include smoke ventilation or AOVs, refuges, fire service access, risers and hydrants. A clear key and coordinated revision references help future users understand the information.
For an existing Leeds property, a drawing should make clear whether it represents recorded design intent or evidence of the current arrangement. A historic compartment line should not be labelled as verified merely because it appears on a plan. Later alterations need review so the drawing and written strategy remain consistent.
The design basis: Approved Document B and British Standards
For Leeds projects, the report identifies the applicable England Building Regulations requirements and selected design route. Approved Document B addresses warning and escape, linings, structure and compartmentation, external spread, and firefighting access and facilities. The relevant edition and transitional provisions need to be checked against the proposed work and project dates.
For an existing building, a contemporary standard should not be treated as proof of its original construction or applied without considering the purpose of the assessment. The strategy needs to distinguish the existing design basis from requirements arising from new work. Relevant higher-risk building applications also need the appropriate Building Safety Regulator process and a commission suited to that work.
BS 9991:2024 for residential buildings within its scope
BS 9991 addresses fire safety in the design, management and use of residential buildings within its scope. A strategy using this route may examine protected stairs, common corridors, compartmentation, fire doors, warning, smoke control, fire resistance, evacuation and firefighting facilities. The selected approach must suit the actual building. The presence of accommodation does not automatically make every residential or specialist premises suitable for the same method.
BS 9999:2017 for suitable buildings within its scope
BS 9999 can support a risk-based approach for suitable buildings such as offices, retail premises, hospitality, industrial premises and warehouses. Occupancy characteristics, fire risk and management assumptions influence the assessment of escape and protection measures. It is not a code for individual dwelling houses. A strategy should apply the relevant provisions coherently rather than selecting isolated allowances from different routes.
BS 7974:2019 and the supporting PD 7974 series
BS 7974 provides a framework for applying fire safety engineering principles. A specialist assessment starts with defined objectives and a qualitative design review, then uses appropriate analysis to evaluate potential solutions against agreed criteria. Relevant parts of the PD 7974 series can support the methodology. This route is useful when a specific design question needs engineering analysis; it is not an automatic requirement for every report.
Standards for the systems supporting the strategy
Related system standards can include BS 5839-1 for non-domestic fire detection and alarm systems, BS 5839-6 for systems in domestic premises, BS 5266-1 for emergency lighting and the relevant BS EN 12101 standards for smoke-control components or systems. The strategy identifies the required function, while specialist designers confirm applicable standards, editions and detailed specifications for their work.
British Standards are technical standards, not the legislation itself. The report should state the selected design basis, applicable editions and any departures, with the reasons and supporting evidence. It should explain how the chosen standards address your building’s design, so you can understand the requirements and any limitations.
Fire engineering, CFD modelling and alternative designs
Some buildings need a more detailed assessment of an open-plan arrangement, retained stair, basement, atrium or another feature that does not follow a conventional guidance solution. The first step is to define the departure and the safety objective. A competent specialist then identifies relevant fire scenarios, occupants, assumptions, analysis methods and acceptance criteria. The scope may include calculations or modelling, with suitable technical review.
CFD means computational fluid dynamics. In an appropriate fire engineering study, it can help examine smoke movement and conditions in a defined scenario. Its value depends on justified inputs, a suitable model and careful interpretation. A visual simulation alone is not evidence that a proposal is acceptable.
Available Safe Egress Time (ASET) concerns the time available before the specified conditions become untenable in the scenario assessed. Required Safe Egress Time (RSET) considers the time needed for detection, warning, occupant recognition and response, and movement to safety. Where this comparison is used, the assessment needs suitable safety margins and consideration of uncertainty; a simple numerical comparison is insufficient on its own.
The findings may support additional detection, smoke control, suppression, improved compartmentation, fire-resisting construction or different escape arrangements. The appropriate measures follow the analysis. An engineered solution does not promise that walls, stairs or sprinklers can be avoided. Specialist modelling, calculations and review are separately scoped and priced where justified.
Fire strategy report, fire risk assessment or certificate?
These documents answer different questions. Knowing the purpose helps you commission the correct service:
- Fire strategy report: explains the building’s fire safety design, its assessment basis and the measures and assumptions that work together.
- Fire risk assessment: examines fire risks and precautions in the premises as used, including management matters and actions. It can identify a need for design clarification, but does not automatically supply that technical assessment.
- Fire strategy drawing: illustrates relevant design provisions on the plans. It accompanies the assessment where commissioned; a drawing alone may not explain the reasoning or limitations.
- Fire alarm certificate: records a specified design, installation, commissioning or maintenance activity for the alarm system. It does not certify the whole building’s fire strategy.
- Evacuation plan: explains the operational arrangements for getting people to safety, including assistance where needed. It must be consistent with the strategy and actual building management.
- Fire alarm zone plan: helps identify alarm zones and locations. It has a different purpose from the coordinated escape, compartmentation and protection information in fire strategy drawings.
Send the exact wording of any request from an authority, assessor or managing agent. We can then identify the appropriate document and any related services that need a separate scope.
Our process for a Leeds strategy or retrospective review
- Understand the issue. Provide the address, building use, current plans, previous strategy and fire risk assessment where held. Include the exact action or design question you need answered, plus any proposed alterations and programme constraints.
- Review the available evidence. We identify the useful records, inconsistencies and information gaps. The appointment states the survey scope, access requirements, drawings, specialist investigations, technical review and report stage. For occupied premises, arrangements for access need to be coordinated with the people managing the building.
- Assess the arrangements and changes. The strategy examines the relevant design provisions and identifies what the evidence supports. Where a hidden feature needs investigation, that need is recorded. Proposed fit-outs or refurbishments are assessed against the wider building arrangements on which they rely.
- Issue a coordinated report. The agreed review is completed, drawings are referenced and the report distinguishes conclusions from unresolved matters. This gives the owner and design team a clearer basis for deciding which design, investigation or remedial tasks should follow.
- Maintain the information through the project. Changes and new survey findings may require an update. For relevant work in England, Regulation 38 fire safety information should be coordinated at handover. An updated strategy can form part of that record, alongside appropriate final drawings and specialist information, within the agreed commission.
Professional credentials, review and insurance
Our fire-safety team includes professionals holding Member grade of the Institute of Fire Safety Managers (MIFSM) and Associate membership of the Institution of Fire Engineers (AIFireE). Spycon Security Ltd holds IFSM affiliate membership, a company affiliation separate from individual professional membership.
Your appointment identifies the competent author and technical reviewer responsible for the report and its sign-off. Work is matched to the competence required; professional membership or an electrical qualification alone does not establish competence for every complex fire engineering assessment.
Professional Indemnity, Public Liability and Employers’ Liability insurance is arranged through NAPIT, subject to the relevant policies, insured activities and limits.

Leeds fire strategy questions
We have no original fire strategy. Where do we start?
Send the current floor plans, fire risk assessment and any approval, inspection or refurbishment records you hold. We assess the evidence and define whether a retrospective strategy, additional survey work or another targeted assessment is needed.
Does an old report become invalid after a fixed number of years?
A fire strategy is not normally a periodically renewed service certificate. Its usefulness depends on whether it still represents the building, use and relevant assumptions. Alterations or new information can create a need for review.
Can you review one floor of a larger office building?
The commission can focus on a tenant’s works, but shared escape routes and systems may require information about the wider property. Send the base-building strategy and landlord’s fit-out requirements with your plans.
Can one strategy cover an entire property portfolio?
A portfolio can use a consistent reporting format and enquiry process, but each building needs a suitable assessment. A common template cannot establish the fire safety arrangements of different premises.
Does a retrospective strategy prove that every fire door is compliant?
No. A strategy can identify door requirements and relevant design assumptions. Establishing the condition and suitability of individual doors needs an appropriate inspection and evidence. Any fire door survey or remedial work is separately defined.
Can work start while important construction evidence is missing?
The implications depend on what is unknown and which design decisions rely on it. The report identifies those dependencies so the project team can establish what must be investigated or resolved before relying on the proposed arrangement.
Does commissioning a report mean the building is unsafe?
A request may arise because records are missing, the use is changing or a design decision needs clarification. The assessment should establish what the evidence supports and identify any issues found. The request itself does not establish the outcome.
