Fire-rated riser doors — also known as service-cupboard fire doors or fire-rated access panels — are certified access doorsets that maintain the fire compartmentation of a wall wherever it is opened up to reach services. They are specified for service risers and shafts, electrical, meter and comms cupboards, and ductwork access, and will be available across the FD30 to FD120 range within the certified scope, in metal (steel) or timber-based construction to suit the position. As with any fire door, the rating describes integrity (FD/E to BS EN 1634-1, classified under BS EN 13501-2) rather than insulation (EI); where a specification also calls for insulation, EI classification evidence is required.
A riser door or access panel only performs if it is certified and installed as a complete assembly. Every unit we supply will be a factory-made doorset — frame, leaf or panel, intumescent protection and seals tested together under a third-party certification scheme — rather than a panel dropped into a separately formed builder's opening. That matters at riser positions in particular, because an unrated or poorly formed access opening is one of the most common compartmentation breaches found in fire door surveys. Sizes and configurations will be confirmed at enquiry against the certified field of application, with no on-site cutting or modification of the certified assembly.
Riser doors have to balance fire compartmentation with routine maintenance access, so the hardware is specified to match how the opening is used. Where a riser is kept locked shut, keep-locked hardware and BS 5499 'Fire door keep locked' signage are typically specified; where the fire strategy requires the door to close itself — for example where it serves an escape route — a self-closing device to BS EN 1154 will be fitted within the certified design. Intumescent seals are provided to the certificated specification, with cold smoke seals added where smoke control is required. Each doorset will be delivered with its certification evidence and installation instructions aligned to BS 8214, ready for the fire door register and Regulation 38 handover records.
Specification
| Fire resistance | 30 to 120 minutes' integrity (FD30-FD120; broadly E30-E120 under BS EN 13501-2), selected to match the compartment and the certified design |
| Construction | Metal (steel) or timber-based riser doorsets and access panels, as covered by the doorset's certification scope |
| Tested assembly | Certified and supplied as a complete unit — frame, leaf or panel and seals tested together; not a panel fitted into a separately formed opening |
| Seals | Intumescent seals to the certificated design; cold smoke seals added where smoke control is required |
| Testing route | BS 476-22 or BS EN 1634-1, classified to BS EN 13501-2 on the European route |
| Closing and locking | Keep-locked hardware for normally locked risers; self-closing devices to BS EN 1154 where the fire strategy requires the door to self-close |
| Access format | Single or double-leaf riser doors and smaller access panels; beaded or flush frame profiles within the certified field of application |
| Sizes and configurations | Confirmed at enquiry against the certified field of application; no on-site cutting or modification of the certified assembly |
| Glazing options | Glazing is uncommon at riser positions; where offered, factory-fitted fire-rated vision panels strictly within the certified field of application, with no site cutting of apertures |
| Ironmongery | CE/UKCA-marked hardware within the certification scope: hinges to BS EN 1935, closers to BS EN 1154 where fitted, compatible locks and latches |
| Third-party certification scheme | Published at launch |
| Lead times | Published at launch |

Fire door supply →Frequently asked questions
What is a fire-rated riser door?
A fire-rated riser door is an access doorset that keeps a compartment wall's fire resistance intact where the wall is opened up to reach services — service risers, meter and comms cupboards, ducts and similar voids. It is also referred to as a service-cupboard fire door or a fire-rated access panel. Like any fire door it is rated for integrity (FD/E to BS EN 1634-1), and it should be certified and installed as a complete assembly, not a loose panel fitted into a builder's opening.
Do riser doors have to be self-closing?
It depends on how the opening is used and what the fire strategy requires. Many riser and service cupboards are kept locked shut, in which case keep-locked hardware and 'Fire door keep locked' signage are used rather than a self-closer. Where the door could be left open or serves an escape route, the fire strategy may require a self-closing device to BS EN 1154. The requirement comes from the building's fire risk assessment and fire strategy, not from a general rule.
Is a fire-rated access panel tested as an assembly?
Yes. A fire-rated access panel or riser door is tested and certified as a complete assembly — the frame, the leaf or panel and the seals together — because the performance depends on how those parts interact. Fitting a certified panel into a separately formed opening, or modifying the assembly on site, invalidates that evidence. Every unit we supply will be a factory-made doorset within its third-party certification scope, with sizes confirmed at enquiry against the certified field of application.
What fire rating does a riser door need?
The rating of a riser or service-cupboard door should match the compartment it sits in, which is set by the building's fire strategy and Approved Document B — commonly FD30 or FD60, and up to FD120 for higher-duration compartment lines. The rating describes integrity, not insulation: if the specification calls for EI performance, the doorset needs EI classification evidence rather than an integrity-only rating. We will confirm the achievable rating and configuration against manufacturer certification data at enquiry.
