Health and safety legislation sits at the centre of every construction project in the UK. Construction remains one of the highest-risk industries to work in, so health and safety regulations exist to protect workers, the public, and construction businesses. For project managers, understanding this framework is not optional.
This guide explains the principal regulations that apply to construction in the UK, sets out who is responsible for compliance, and looks at why meeting these obligations matters. It also covers practical ways to stay informed as legislation evolves, so that your approach to health and safety in construction remains current.

The Important Health and Safety Regulations in Construction
Health and safety in the construction industry is governed by several pieces of legislation that combine with each other to provide a wide-ranging scope of protection. Some apply to all workplaces, while others are written specifically for construction sites in recognition of the unique risk factor of the work.
Understanding how these regulations overlap is the first step towards effective compliance. These are three of the most significant pieces of legislation that managers in the construction sector should familiarise themselves with.
The Health and Safety at Work etc. Act 1974
The Health and Safety at Work etc. Act 1974 is the foundation of health and safety law in the UK. It applies across virtually every industry, including construction, and establishes the broad duties that everyone in the workplace must follow.
Under the Act, employers have a general duty to ensure, so far as is reasonably practicable, the health, safety, and welfare of their employees. This includes providing safe systems of work, suitable equipment, and appropriate training.
The Act also places duties on employees, who must take reasonable care of their own safety and that of others affected by their work. Because its scope is so wide, the 1974 Act underpins the more specific health and safety regulations in construction that follow.
The Construction (Design and Management) Regulations 2015
The Construction (Design and Management) Regulations 2015, usually known as CDM 2015, are the core regulations written specifically for construction projects. They apply to all construction work, regardless of size, from minor refurbishments to major builds.
CDM 2015 defines a series of duty holders and sets out their responsibilities. These include clients, principal designers, principal contractors, designers, contractors, and workers, each of whom has a defined role in managing risk throughout a project.
The regulations require that health and safety is considered from the earliest design stage and managed continuously through to completion. For larger or longer projects, additional requirements apply, such as appointing the right duty holders and notifying the Health and Safety Executive.
CDM also requires that everyone appointed to a project has the skills, knowledge and experience their role demands. On site, a CSCS card is the common way workers evidence that competence before they start.
The Work at Height Regulations 2005
Falls are one of the most common causes of serious injury on construction sites. The Work at Height Regulations 2005 address any work carried out at height where a person could fall and injure themselves.
The regulations set out a clear hierarchy for managing risk. Working at dangerous heights should be avoided where possible. When working at height is absolutely necessary, suitable equipment should be provided in order to reduce the chance of a fall and to mitigate the consequences if a fall happens.
Employers must ensure that work at height is properly planned, supervised, and carried out by trained professionals. Given the frequency of incidents, inspectors will pay close attention to height risk when auditing a site, so remaining compliant should be a priority for site managers.
Other Key Construction Health and Safety Regulations
Beyond the three foundations above, several more regulations shape day-to-day site safety. The ones below apply on almost every construction project.
Require every employer to assess risks and record the significant findings. The legal basis for risk assessments.
Control of Substances Hazardous to Health. Requires you to assess and control exposure to dust, fumes and chemicals.
Aim to reduce injury from lifting, carrying and moving loads, a leading cause of long-term harm on site.
Sets out which workplace injuries, diseases and dangerous occurrences must be reported to the HSE, and when.
The Provision and Use of Work Equipment Regulations. Work equipment must be suitable, maintained and safe to use.
Introduces stricter duties and a golden thread of information for higher-risk buildings.
Management of Health and Safety at Work Regulations 1999
These regulations turn the general duties of the 1974 Act into a specific requirement: every employer must carry out a suitable and sufficient assessment of the risks to workers and anyone else affected by their work. If you employ five or more people, you must record the significant findings.
Risk assessment is the practical heart of construction safety, so it is worth getting right. Our guide to construction risk assessments walks through the five steps and how risk assessments and method statements (RAMS) work together.
COSHH 2002
The Control of Substances Hazardous to Health Regulations 2002, known as COSHH, cover exposure to substances that can harm health, such as dust (including silica), fumes, and chemicals. Employers must assess the risk, prevent or control exposure, and keep the necessary records. On a construction site, silica dust from cutting and grinding is one of the most significant COSHH risks.
RIDDOR 2013
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, or RIDDOR, set out which incidents must be reported to the Health and Safety Executive. Reportable events include deaths, specified serious injuries, injuries that keep a worker off their normal duties for more than seven days, certain occupational diseases, and dangerous occurrences such as a scaffold collapse. Reports must be made within set timescales by the responsible person.
A clear, consistent record of every accident and near miss makes meeting these duties far less painful. Sync’s incident reporting lets teams log accidents and near misses from site, with investigation notes and follow-up actions kept together in one place.
The remaining regulations shown above, the Manual Handling Operations Regulations 1992, PUWER 1998, and the Building Safety Act 2022, apply in specific situations, from moving heavy loads to using plant and working on higher-risk buildings. Each adds duties on top of the general framework rather than replacing it.
Who is Responsible for Regulatory Compliance in Construction?
Responsibility for compliance with health and safety legislation in construction is shared rather than held by any single individual or party. The legal framework deliberately distributes duties so that risk is managed at every stage of a project.
Duty holders range from the client who commissions the work, through the designers and principal contractor who plan and coordinate it, to the contractors and workers who carry it out. Each has obligations appropriate to their role and level of control.
In practice, this means that health and safety is a collective responsibility. While senior duty holders carry the most significant legal obligations, every person on site has a part to play in maintaining a safe working environment. Clear risk management is what keeps those shared duties from slipping through the gaps.
Do You Need a Health and Safety Policy?
If your business has five or more employees, you must have a written health and safety policy. It sets out how you manage health and safety, who is responsible for what, and the arrangements you have in place to keep people safe. Even smaller firms benefit from writing theirs down.
A good health and safety policy for a construction company is not a document that sits in a drawer. It should be current, shared with the team, and backed by the risk assessments, method statements and records that show it working in practice.
The Importance of Complying with Health and Safety Legislation
Complying with health and safety legislation is far more than satisfying a legal requirement. Strong compliance protects people, preserves resources, and safeguards the reputation and financial stability of a business.
The consequences of falling short can be severe, affecting workers, projects, and organisations in different ways.
The most serious cost. Harm to workers affects families, lowers morale, reduces productivity and delays delivery.
Direct repair and replacement costs, plus the knock-on delays that stretch the project budget.
Improvement orders, substantial fines and, in serious cases, prosecution, plus lasting reputational damage.
Injuries to Staff
The most serious consequence of poor health and safety practice is harm to workers. Construction involves significant hazards, and failure to manage them properly increases the likelihood of injuries or fatalities.
Serious incidents affect individual employees and their families, but there are practical consequences too. Injuries can lower morale across the wider team and reduce confidence in management. Absences caused by injury reduce productivity and can delay project delivery.
Damage to Equipment
Poor safety can also lead to damage to plant, machinery, and equipment, often at the same time as causing injuries and compounding the practical consequences.
Equipment damage carries direct costs through repair or replacement, as well as indirect cost by causing project delays. These expenses and delays can quickly compound into a serious financial burden on the project budget and the business as a whole.
Legal Consequences and Penalties
Failing to comply with health and safety regulations in construction can result in legal action against both businesses and individuals.
Penalties range from improvement orders to substantial fines and, in serious cases, criminal prosecution and imprisonment. The scale of the penalty generally reflects the severity of the breach and the harm caused or risked.
Beyond the immediate legal punishment, compliance failures cause reputational damage. Clients, business partners, and prospective employees may all be deterred by a poor compliance record, harming your ability to do business long after the incident.
How to Keep Track of New Construction Health and Safety Legislation
Health and safety legislation in construction is not static. Regulations are reviewed and updated over time, and keeping pace with these changes can be a challenge for busy project managers.
A practical approach is to monitor official sources directly, and to interpret what changes mean in practice through industry bodies and trade associations.
Relying on memory or scattered documents runs the risk of important updates being missed. The most reliable way to keep track of shifts in the regulatory landscape is to have a compliance management system in place that outlines obligations, tracks legislative changes, and makes all relevant information accessible to responsible members of the team.
