Window cleaning at height is one of the most publicly visible forms of work at height in the UK — the cradles swinging from office blocks, the operatives on cherry pickers cleaning hotel facades, the traditional rope-access window cleaner suspended from high-rise rooftops. It is also a form of work that has historically generated fatal incidents serious enough to prompt major changes in regulatory practice. This guide pulls together the verified data from the Health and Safety Executive (HSE) on falls from height, sets out how each window-cleaning method changes the risk profile, and explains the law that now governs the work.
Window cleaning at height: a persistent risk
Falls from height remain the single biggest killer of workers in Great Britain. According to the HSE, falls from height killed 35 workers across all industries in 2024/25, and falls from height have been the leading cause of workplace death in almost every year since 2001/02. Window cleaning fatalities contribute to this total, because so much of the trade is, by definition, temporary work carried out above ground level.
That persistent risk is precisely why window cleaning sits at the centre of working-at-height regulation. The Work at Height Regulations 2005 emerged directly from a series of window cleaning fatalities — scenarios in which temporary work at height was routinely carried out without adequate fall protection. The data has improved as methods have modernised, but the underlying hazard has not gone away.
Key facts & figures
- 35 workers were killed by falls from height across all industries in Great Britain in 2024/25 (HSE).
- Leading cause of workplace death in almost every year since 2001/02 has been falls from height (HSE).
- ~70 ft (21 m) is the approximate building height up to which water-fed pole systems can clean from the ground (HSE guidance).
- 2005 — the Work at Height Regulations were introduced after a series of window cleaning fatalities.
- 6 months — the maximum interval for thorough examination of suspended access equipment under LOLER 1998.
- 2-person minimum on site is required for industrial rope access under BS 7985 and IRATA.
The methods of window cleaning and their risk profiles
Different premises demand different access methods, and each carries its own hazards. The choice of method is itself a safety decision — the regulations require employers to prioritise the option that removes or reduces the risk of a fall.
Water-fed pole (WFP) systems are the most significant safety advance in commercial window cleaning in decades. By cleaning from the ground using purified water and an extendable pole, WFP eliminates the need to access height for buildings up to approximately 70 feet (21 metres). This advance has substantially reduced the number of window cleaning incidents.
Ladders remain the traditional access method for residential and smaller premises where WFP is impractical. The key risks centre on securing the ladder, avoiding overreaching, ensuring a stable base, and inspecting the ladder before each use.
Mobile Elevating Work Platforms (MEWPs) — cherry pickers and scissor lifts — address heights beyond the range of WFP. Their hazards include overturns, entrapment, and falls from the platform.
Cradles and suspended access equipment (SAE) are purpose-designed platforms that descend from roof-mounted davit arms or building maintenance units. This equipment is regulated as lifting equipment under LOLER and requires periodic thorough examination.
Rope access is used for the most demanding high-rise work. It requires specialist training — typically to IRATA Level 1, 2 or 3 standard — and is subject to strict equipment and procedural requirements under BS 7985.
| Method | Typical use | Principal hazards / controls |
|---|---|---|
| Water-fed pole (WFP) | Buildings up to ~70 ft (21 m) | Cleans from the ground — removes the fall risk |
| Ladders | Residential & smaller premises | Securing, overreaching, stable base, pre-use inspection |
| MEWPs | Heights beyond WFP range | Overturns, entrapment, falls from platform |
| Cradles / SAE | High-rise facades | LOLER lifting equipment — thorough examination |
| Rope access | High-rise, restricted access | IRATA training, BS 7985, two-person minimum |
The historical context: why regulations changed
Prior to 2005, window cleaners working from traditional cradles and ladders without adequate training, equipment inspection, or working procedures were dying at a rate that was not accepted in other sectors. The response was the Work at Height Regulations 2005, which reframed the whole approach to temporary work at height.
The key legislative changes introduced a clear hierarchy of duties:
- A duty to avoid work at height where it is reasonably practicable to do so.
- A duty to use collective fall protection before personal fall protection.
- A requirement for regular inspection and maintenance of all equipment.
- A requirement for worker competence and training.
Current legal requirements for window cleaning at height
Several overlapping frameworks now govern the work, depending on the access method used.
Under the Work at Height Regulations 2005, an employer must complete a risk assessment before work begins, select an appropriate access method (prioritising WFP where suitable), provide suitable, regularly inspected and properly maintained equipment, and ensure all workers are trained and competent.
Under LOLER 1998, suspended access equipment must undergo thorough examination by a competent person at intervals no greater than six months, with records of those examinations maintained.
For rope access, BS 7985 and the IRATA standards require the appropriate IRATA training level, equipment inspection before each use plus formal periodic inspection, work positioning systems with backup systems, and a minimum of two people on site at any time.
