Ladders, poles and platforms: cleaning at height in Bristol

Cleaning high up is one of the few tasks in commercial cleaning where a single mistake can cause a serious injury or death. Falls from ladders and from platforms are a common cause of harm in the sector, and the risk rises when the work is done alone, in poor weather or on a surface that is slippery with water or cleaning solution. The Work at Height Regulations 2005 set the legal framework for these tasks in Great Britain. For a Bristol client commissioning window or façade cleaning, the practical question is what the contractor will do to avoid the risk, and what it will do when the risk cannot be avoided.

The duty to avoid work at height

The starting point in the Regulations is avoidance. An employer must not allow work to be done at height where it is reasonably practicable to do it safely in another way. For cleaning, that can mean designing the building so that windows can be reached from inside, fitting a permanent access system, or using a long-reach tool from the ground rather than climbing. A contractor who offers a method that stays on the ground when it is practicable is showing the kind of thinking the law expects.

Avoidance is not always possible, and the Regulations recognise that. Where work at height cannot be avoided, the employer must plan it, organise it, supervise it and make sure that the people doing it are competent. The Health and Safety Executive's work at height pages set out this approach in practical terms and link to the detailed guidance on ladders, scaffolds and other equipment. Cleaning contractors should be able to explain how they apply this approach to each area in the scope.

Choosing suitable equipment

The Regulations require equipment to be chosen according to the task, the duration and the surface. For many cleaning jobs the answer is a water-fed pole system, which lets the operator clean a high window from the ground using purified water that dries without leaving streaks. Poles avoid the need to climb, but they still need a stable base, a sensible reach and a method for dealing with wind and traffic. A pole used in a gusty street can be harder to control than one used in a sheltered courtyard.

Ladders have a place, but they are suited to short, low-risk jobs that do not require the operator to work for long periods or to carry heavy loads. The HSE's advice on ladder use focuses on the duration of the task, the condition of the ladder, the surface it stands on and the way it is secured. A contractor who proposes a ladder for a long shift on a high façade should be asked to justify that choice, and to explain why a platform or a pole system would not be safer.

Mobile platforms and mobile elevating work platforms may be the right answer for larger buildings or for work that needs both hands. Each platform needs to be inspected, operated by a trained person and placed on firm, level ground. Check that the contractor has the necessary training records and that the equipment has been examined in line with the Regulations, rather than simply taking the company's word for it.

Competence and training

Competence is the second pillar, and the HSE's guidance on managing health and safety describes the same expectations for training and supervision. The Regulations require that people working at height are trained and competent for the task, and the employer must make sure that supervision and instruction are in place. A cleaner who uses a pole every day may still need specific instruction on the system, the risks of the building and the procedure if something goes wrong. A cleaner who has never used a platform should not be sent up one without training.

A client does not need to become an expert, but a few questions help. Ask who on the team holds the training for the equipment proposed, how that training is recorded and who supervises the work on the day. Ask whether the contractor has a written method statement for the building, and whether it has been shared with the client's facilities team. A vague answer to any of these points is a warning sign.

The duties to co-operate matter as well. Where a cleaning contractor works on premises controlled by a client, both must share information about the hazards. Section 4 of the Health and Safety at Work etc. Act 1974 places duties on those who control premises, and section 2 places duties on employers towards their staff. The two sets of duties meet at the point where the building's features, such as roof edges, plant areas and gutters, create a fall risk. The client should tell the contractor what they are, and the contractor should explain how it will control them.

Rescue planning

Many fatal falls are not caused by the fall itself but by what happens afterwards. A person suspended from a harness or left on a platform may be unable to get back to safety, and a delay in rescue can be dangerous. The Regulations expect employers to plan for rescue where a fall is possible, and the plan should be realistic for the building and the equipment in use.

For cleaning work, a rescue plan usually covers how the operator will be reached, who will raise the alarm and how the emergency services will be called if the local fire and rescue arrangements are needed. A contractor working alone at height has a particular problem, because nobody else may be present to notice a problem. The HSE's lone working guidance is relevant here, since it sets out the employer's duties to provide support and monitoring for people working alone. Ask the contractor how check-ins are carried out and who responds if one is missed.

Weather and site conditions

Bristol's wet and often windy weather affects high-level work in obvious ways. Rain makes surfaces slippery and can make ladders and platforms unsafe. Wind can move poles and platforms, and it can carry water in unexpected directions. The contractor should have a rule for stopping work in bad weather and should record when the rule was applied. A contract that requires cleaning to continue regardless of conditions is not one the client should accept.

Site conditions also matter. Pedestrians and traffic below the work need to be kept clear, usually by barriers or a temporary traffic management arrangement where the work is near a road. Overhead cables, skylights and fragile roofs all need to be identified before the work starts. A survey of the building's features is the place to note these hazards, and it is part of the same survey that shapes the price.

What to ask a contractor

Before accepting a quote that includes high-level work, ask for a written explanation of the method for each area, the equipment proposed and the reason for choosing it. Ask how the work will be avoided where possible, what training the team holds and how the building's fall risks will be controlled. Ask for the method statement and the risk assessment, and check that the rescue and check-in arrangements are described.

The cost of safe high-level work is not always the lowest figure on a quote. Competent operators, suitable equipment and proper supervision all take time, and a contractor who has priced them properly is more likely to deliver a result that is both safe and consistent. The guide on one-off deep clean costs explains how these items feed into a quote more generally.

When you are ready to compare, you can request quotes that state the method and the height of each area, or look through the commercial cleaning services available for multi-storey premises. Matching the method to the building is what makes the work both safe and reliable, and the matting and wet-weather routines guide covers the seasonal side of the same planning.
