| Item | Why it matters | Who decides | Ask |
|---|---|---|---|
| Scale | A fitting that looks right from one landing can be lost, or crowd the stair, from another | Lighting designer; interior designer | Has the fitting been checked from every landing and from the stair itself? |
| Load path | A heavy suspended load over people; the structure above the void may be a roof, a slab or a rooflight | Structural engineer | Is the fixing designed for this fitting and this structure, and signed off? |
| Secondary suspension | A second path in case the first fails, over a stair or lobby where people pass beneath | Structural engineer; partner workshop | Is there a second path, and does the engineer approve it? |
| Stair and balustrade | The fitting and its drops must stay clear of the stair headroom and the balustrade | Architect; stair designer | What is the clearance to stair, handrail and balustrade, and who checked it? |
| Fire and smoke strategy | Large fittings can obstruct smoke vents, sprinklers, detectors or emergency lighting | Fire engineer | Has the fire engineer seen the fitting and its position? |
| Access for maintenance | Cleaning and re-lamping a high fitting is work at height, and lowering gear is lifting equipment | Operator; designer; installer | How does a person reach or lower it, and is that on the drawings? |
| Getting it in | Large fittings are delivered in sections and must go through the stair void and the door | Partner workshop; installer | Can it be built in sections, and what route does each take? |

Scale and sightlines in a void
A stair void or atrium is viewed from many levels, so the fitting has to work from the lower floor looking up, from each landing across and from the stair itself. Check the scale in three ways: on the section, from the sightline of each landing, and in a mock-up or full-size cut-out hung in the void before the fitting is made. Our sheet on chandelier sizing and hanging heights covers the usual sizing conventions for rooms; a void is a different case because the fitting is seen from above and from the side as well as from below, and the usual rules cannot be carried over unchecked.
The drawing is a section through a stair void. The dashed ring is the clear zone round the fitting, in which nothing should be, including the balustrade, the stair, the drops when the fitting is moved, and the equipment used to maintain it. How large that zone must be is for the designer, the stair designer and the installer to set for the fitting; this sheet gives no distance. For headroom over the stair, use the figures in the Approved Document and our sheet on stair rise, going and headroom, and check any hanging fitting against them in your own jurisdiction.
Structure, secondary suspension, stair and fire
A heavy suspended load over a place people use. A fitting over a lobby floor or a stair is a load above people, so the consequence of a failure is high. The structural engineer designs the fixing for the declared weight, as set out in our sheet on chandelier weights and ceiling loads, and approves any secondary suspension. In a void the structure above may be a roof or an unusual slab, so do not assume a standard ceiling detail.
Secondary suspension. A second, independent path from the fitting to the structure is common practice for a large fitting over circulation. Whether one is required, what it consists of and how it is fixed are for the engineer. See suspending heavy lighting for the principle.
Balustrade and stair. The fitting is not part of the stair, but it hangs beside it. Check the clearance to the handrail and balustrade, to the stair headroom, and to anything a person could reach and swing. Balustrade and handrail rules and staircase anatomy and terminology give the context.
Fire and smoke. Atria and stair voids are often part of the smoke control or escape strategy. Ask the fire engineer to look at the fitting’s position and size against smoke vents, sprinklers, detectors and the emergency lighting. See emergency lighting and decorative luminaires. We have not read the fire guidance for this sheet and give no rule.
Access and maintenance options
The cheapest-looking option at design stage can be the most expensive to live with. Decide how the fitting will be cleaned and re-lamped before it is designed, because the answer changes the fixing, the structure and the drawings. The table sets out the main options and the points to settle with the right person. It is a list of questions, not a recommendation.
| Option | What it needs | What it means for safety | Who to ask |
|---|---|---|---|
| Fixed access: platform, gantry or catwalk above or beside the fitting | A permanent safe place to work, with a route to it; the structure must carry it | Work at height is reduced to a protected position; the platform is a structure for the engineer to design | Architect; structural engineer |
| Temporary access: scaffold or mobile tower each time | Space on the floor for the equipment; a floor that can take it; time and cost each visit | Work at height with the usual controls; stair voids can make a tower awkward or impossible | Operator; installer |
| Mechanical access platform | Floor space, a floor that can carry it, a route in | Work at height with the usual controls; may not reach over a stair | Operator; installer |
| Lowering gear (manual or motorised winch) | A structural point for the winch, the routing and a clear drop zone to the floor; a place for the controls | Lowering gear is lifting equipment, so the lifting regulations apply; see the hoists sheet | Installer; operator; competent person |
| Design the fitting to be serviced in place from a platform, or in sections lowered separately | Joints, access and handling designed in from the start | A partner workshop can advise what is practical for the fitting | Partner workshop; designer |
What the regulations say, in brief. Under the Work at Height Regulations 2005, regulation 6, employers must ensure that work is not done at height where it is reasonably practicable to do it safely otherwise, and where work is done at height must take suitable and sufficient measures to prevent falls, so far as reasonably practicable. Under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), regulation 8, every lifting operation involving lifting equipment must be properly planned by a competent person, appropriately supervised and carried out in a safe manner. Under regulation 9 of the Construction (Design and Management) Regulations 2015, designers must eliminate foreseeable risks to people who maintain or clean a structure so far as reasonably practicable. Taken together, these push the question of access back to the design stage. Our sheet on chandelier hoists and lowering gear deals with lowering gear and LOLER in more detail.
This sheet is not legal or health and safety advice. The duty-holder, the competent person and the installer’s method statement decide how the work is done in your building.

Questions we are asked
How do you clean a chandelier in a stairwell or atrium?
It depends on the access chosen at design stage: a fixed platform, a mechanical platform or scaffold each visit, or lowering gear. Each has different structural, safety and legal consequences, so decide it before the fitting is made and draw it.
Does a chandelier winch have to be inspected?
Lowering gear is lifting equipment, so the lifting regulations apply to it, including planning and examination duties for the duty-holder. See our sheet on chandelier hoists and lowering gear, and take advice from a competent person.
How big should a chandelier be in a double-height space?
There is no single rule. Check the scale on the section, from every landing and in a full-size mock-up. The sizing conventions for ordinary rooms do not carry over unchecked.
Does a chandelier need a secondary suspension over a stair?
Many large fittings over circulation have one, but whether one is required and how it is fixed are for the structural engineer to decide for your fitting and structure.
How do large chandeliers get into a stair void?
They are usually built in sections that are delivered and assembled on site. Ask the partner workshop how the fitting divides, what each section weighs and what route each takes, and ask the installer for a method statement.
Does the fire strategy affect a chandelier?
It can. A large fitting can obstruct smoke vents, sprinklers, detectors or emergency lighting. Ask the fire engineer to review the position and size before manufacture.
