Fire damper testing for facilities teams: provider comparison

Set the maintenance duty and test scope first

For England and Wales, the Fire Safety Order requires the responsible person to maintain relevant fire-safety measures in efficient working order through a suitable maintenance system. Government guidance says inspection, testing and servicing should be regular and suitable, with competent people carrying out the work. This is the legal duty; it should not be restated as a universal statutory “annual certificate” requirement.[7]

BESA describes BS 9999:2017 as guidance for testing fire dampers on installation and at least annually thereafter, with more frequent attention in dusty or polluted environments. Agree the site-specific schedule against the fire risk assessment, relevant standards, damper manufacturer instructions and the authority having jurisdiction. Ask bidders to identify the standard and edition behind their proposed interval.[8]

Fire damper testing providers at a glance

VSS publishes the clearest handover specification of the four; PTSG, VSS and Marlowe describe access or remedial support, while Rock confirms UK-wide service but gives less detail on those deliverables.[1][2][3][6]

Methodology: This comparison uses undated, vendor-published capability statements. No supplied source provides independent performance results, so the comparison covers stated scope rather than proven service quality.[1][2][3][6]

Which provider specifies the most usable handover?

VSS lists the most detailed reporting fields: damper location, size, type and manufacturer; a unique asset number; functional status; position on ventilation drawings; access restrictions; remedial requirements; and photographs showing the damper open and closed.[2]

PTSG says its reports cover every tested damper, with photographs before, during and after testing. Where it finds problems, it also provides further photographs, remedial advice and detailed costings.[1]

The supplied Marlowe and Rock pages do not confirm equivalent asset-register fields, drawing references or photographic formats.[3][6] This is an evidence gap, not proof they cannot provide them.

Define the required handover in the quotation:

• register format and unique asset-numbering convention;
• drawing references and location descriptions;
• access restrictions for future visits;
• test status and agreed defect classifications;
• required photographs for each asset;
• actions completed and work still outstanding.

Request a redacted sample report and confirm whether its fields can be imported into the existing asset-management system.

Who can solve access problems and complete remedial work?

PTSG says dampers must be located and made accessible before testing, but it can identify them from schematics or physical inspection and install hatches or access panels.[1] VSS offers access-door supply and fitting alongside cleaning, inspection and remedial work.[2] Marlowe describes difficult-location work, access-panel installation, fusible-link sourcing and replacement, damper replacement, and fire-stopping inspection and rectification.[3]

Rock confirms cleaning, lubrication, drop testing and resetting. Its supplied page does not define technical access requirements or confirm access-panel installation, component replacement or wider remedial work.[6]

Require bidders to classify each asset as:

• located and tested;
• located but inaccessible;
• not located;
• failed;
• repaired during attendance; or
• requiring a return visit.

Set approval rules and rates for opening ceilings, installing access panels, replacing components and reinstating fire stopping. The provider pages do not publish comparable charges or approval arrangements for this work.[1][2][3][6]

Where is UK coverage confirmed?

VSS advertises inspections across the UK, including Northern Ireland. Rock describes its operations as UK-wide and offers national-account and regional contact routes.[2][6]

The supplied PTSG and Marlowe pages do not define their service geography.[1][3] For portfolios, require written confirmation of every postcode, the reporting format and any regional or mobilisation charges.

Can prices and contract terms be compared?

No defensible headline price comparison is available. None of the supplied provider pages publishes a comparable fixed testing price, per-damper rate, minimum charge, call-out fee, VAT treatment, quotation-validity period, contract length or cancellation policy.[1][2][3][5][6]

Ask each bidder to separate charges for the initial survey, each tested damper, unsuccessful access, access-panel installation, repairs, replacement parts, return visits and register or drawing production. The sources do not confirm how any provider charges for inaccessible or unidentified dampers.[1][2][3][6]

What should the testing quotation cover?

For comparable bids, specify visual inspection for damage, obstruction and installation faults; activation or drop testing; confirmation of full closure; cleaning where included; resetting; and documentation of findings and actions.[1][2][5][6]

Provider pages broadly describe annual testing, but the contract should cite the actual technical basis and the agreed risk assessment. BESA’s account of BS 9999:2017 supports at least annual testing as an industry-standard baseline; contaminated environments may call for more frequent checks. Do not describe a provider’s wording as legislation.[1][2][3][5][8]

For automated dampers, establish whether the fire-alarm or controls contractor must attend simultaneously. VSS says this may be needed to verify operation between the central control panel and dampers.[2]

How to obtain comparable quotations

Issue every bidder with the same estate information, deliverables and access assumptions:

• Define the estate: list each site, known damper count, suspected unidentified assets, drawing quality, working-hour restrictions and controlled areas.
• Set the discovery method: require bidders to explain how they will locate dampers where drawings are incomplete and what happens when an asset cannot be found or reached. PTSG describes identification from schematics or physical inspection, while PTSG and VSS offer access-panel support.[1][2]
• Specify the handover: require a unique identifier, location, drawing reference, type, size, identifiable manufacturer, functional result, access restriction, defect, action taken and next action. These fields reflect VSS’s published reporting scope.[2]
• Define photographic evidence: request open-and-closed images or an agreed equivalent, plus defect and remedial photographs. VSS and PTSG describe photographic reporting.[1][2]
• Separate additional costs: request itemised prices and approval thresholds for access panels, repairs, replacements, fire-stopping and return attendance.[1][2][3]
• Expose commercial assumptions: ask for exclusions, controls-contractor dependencies, quotation validity, VAT treatment, minimum charges, response times, contract duration and cancellation terms.[1][2][3][5][6]

How to choose the best fit

• VSS: the clearest published match where detailed asset fields, drawing references, access restrictions, open-and-closed photographs and confirmed Northern Ireland coverage are priorities.[2]
• PTSG: a documented match where damper identification, access-panel installation, staged photographs and costed remedial advice matter. Geographic coverage needs written confirmation.[1]
• Marlowe: publishes a broad remedial scope, including difficult-location work, replacement and fire-stopping rectification. Detailed handover fields and service geography need confirmation.[3]
• Rock Compliance: confirms UK-wide delivery, but its quotation should define reporting, access support and remedial deliverables.[6]

Before appointment, obtain a sample report, written scope, evidence of engineer competence, insurance documents, independently checkable references and complete commercial terms. None of the supplied sources provides independent outcome evidence sufficient to identify an overall best provider.[1][2][3][6]
