The Manual Handling Operations Regulations 1992 - usually shortened to MHOR - are the main UK rules covering how loads should be moved safely at work. They are enforced by the Health and Safety Executive (HSE) and sit alongside the broader Health and Safety at Work etc. Act 1974.
This guide explains what MHOR actually requires in plain English, without the legal jargon, so employers and employees both understand their part. For the wider picture, see our complete Manual Handling Training guide.
Key takeaways
- MHOR 1992 applies wherever there is a risk of injury from manual handling.
- The core duty is a three-step hierarchy: avoid, assess, then reduce the risk.
- The regulations do not set a maximum legal weight - they require risk assessment instead.
- Training and information help employers meet their duty and protect their workforce.
What do the regulations require?
MHOR places a clear duty on employers to manage the risk of injury from manual handling. The duty follows a simple order of priority, often called the avoid-assess-reduce hierarchy:
- Avoid hazardous manual handling so far as is reasonably practicable - for example by redesigning the task or using equipment.
- Assess the risk of any handling that cannot reasonably be avoided.
- Reduce the risk of injury to the lowest level reasonably practicable.
Employers must also give workers general information about loads, and precise information on weight where reasonably practicable.
Is there a legal weight limit?
No. This is the single most misunderstood point about MHOR. The regulations deliberately do not set a maximum lifting weight. Instead, the HSE provides guideline filters - around 25kg for men and 16kg for women under ideal conditions - to help flag tasks that need a closer look. These are screening filters, not safe limits, and they must be reduced when the task involves twisting, reaching, repetition or awkward posture. See our guide to manual handling weight limits in the UK.

Employers must assess and reduce risk, provide information and training, and review assessments when things change. Employees also have duties: to follow the systems of work provided, use equipment properly, and take reasonable care of their own and others' safety.

How to comply in practice
In practical terms, compliance means carrying out manual handling risk assessments using the TILE approach, providing suitable training, supplying handling aids where they help, and keeping records up to date. Awareness training such as the online Manual Handling course supports this by making sure everyone understands the principles - with task-specific training added by the employer where needed.
A quick note on compliance. This online course supports awareness and understanding of safe manual handling. Employers may still need to provide task-specific training, supervision and workplace risk assessments. Workers should always follow their employer's procedures, manual handling assessments and internal safety rules. Online learning does not automatically replace hands-on or workplace-specific instruction where that is required.
Frequently asked questions
What are the Manual Handling Operations Regulations 1992?
They are the UK regulations that require employers to avoid, assess and reduce the risk of injury from manual handling at work. They are enforced by the HSE and apply wherever handling could cause injury.
Do the regulations set a maximum lifting weight?
No. MHOR does not set a legal maximum weight. The HSE publishes guideline filters (around 25kg for men and 16kg for women under ideal conditions) as a screening tool, not a safe limit, and a full risk assessment is what really matters.
Who must comply with MHOR?
Employers carry the main duty, but employees also have responsibilities to follow safe systems of work and use equipment correctly. The regulations apply across virtually every UK workplace where handling occurs.
How does training help with compliance?
Training ensures workers understand safe technique and the risk-assessment approach, which supports the employer's duty to reduce risk. It is one part of compliance, alongside risk assessments, equipment and supervision.
