A contractor arriving to test appliances, service extinguishers or inspect fire doors may only be on site for a few hours. That does not remove the need for a clear health and safety risk assessment for contractors. Short-duration work can still affect employees, pupils, patients, visitors, building users and the contractor’s own staff – particularly where work takes place in occupied premises.
For the person responsible for the building, a suitable assessment is practical evidence that the job has been planned properly. It helps prevent avoidable disruption, clarifies who is responsible for what, and gives everyone on site confidence that the work can proceed safely.
Why contractor risk assessments matter
Under UK health and safety law, employers and those in control of premises have duties to protect people who may be affected by work activities. Contractors also have duties to assess the risks their work creates and to provide competent people, suitable equipment and safe systems of work.
A risk assessment is not simply a document to file before an engineer arrives. It should identify the hazards connected with a particular task and location, decide who could be harmed, set out sensible control measures, and be reviewed if conditions change. The level of detail should match the work. A routine visual inspection in a quiet office needs a different approach from electrical testing across a busy school, care setting or shared commercial building.
The assessment also supports cooperation between the contractor and the client. The contractor understands their method of work, while the site duty holder understands local risks such as restricted access, vulnerable occupants, lone working arrangements, alarm procedures and areas that must remain operational. Neither party should make assumptions about the other.
What a health and safety risk assessment for contractors should cover
The starting point is a clear description of the work. This includes where it will take place, the expected duration, equipment being used and whether the activity could affect normal operations. A good assessment then considers hazards created by the task and hazards already present at the site.
For PAT testing, this may include trailing test leads, temporary isolation of equipment, damaged appliances, overloaded sockets, work at desks or in plant areas, and access to equipment located at height. For fire safety work, considerations can include access routes, working around occupied areas, temporary removal of extinguishers, door inspection activity, and maintaining clear escape routes throughout the visit.
The assessment should identify who may be affected. That could include the contractor’s engineer, employees, cleaners, visitors, tenants, delivery drivers, pupils, residents or patients. In schools, healthcare environments and public-facing premises, the controls may need to account for people who are less able to recognise or avoid a temporary hazard.
Control measures must be specific enough to be useful. For example, stating that an engineer will “work safely” is not a control measure. A more meaningful approach may involve scheduling work outside peak periods, using barriers or clear signage around test leads, agreeing a contact person on site, maintaining access to fire exits, and stopping work when an unexpected condition makes the planned method unsafe.
Responsibilities of the client and contractor
Responsibility is shared, but it is not identical. The contractor is responsible for carrying out their work safely, ensuring their personnel are competent and properly trained, maintaining suitable equipment, and providing task-specific information where required. They should also follow site rules and report any hazards or unsafe conditions identified during the visit.
The client or person in control of the premises must provide relevant information about the building and its occupants. This may include site induction requirements, asbestos information where relevant, emergency procedures, access restrictions, welfare arrangements, known electrical defects, safeguarding requirements and times when certain spaces cannot be entered.
Where work is part of a construction project, the Construction (Design and Management) Regulations may impose additional duties. These depend on the scale and nature of the project, so routine compliance visits will not always require the same documentation as refurbishment or construction work. The principle remains the same: risks must be managed by the people best placed to control them.
A competent contractor will ask sensible questions before work begins rather than treating every site as identical. Equally, a site representative should be available to explain local arrangements and respond if access, occupancy or site conditions change.
Planning the assessment before work starts
The most effective assessments are prepared before the engineer is at reception. A pre-job discussion allows both parties to identify practical issues early, avoiding delays on the day and reducing the risk of work being carried out in unsuitable conditions.
A straightforward planning process usually includes:
- confirming the scope of work, locations and anticipated timescales;
- identifying site-specific hazards, restrictions and vulnerable building users;
- agreeing access, parking, sign-in, security and safeguarding procedures;
- checking emergency arrangements, including fire alarm procedures and evacuation routes;
- deciding how the work area will be kept safe and how disruption will be minimised.
For larger, unusual or higher-risk premises, an on-site survey may be appropriate before the work is booked. This is particularly useful where access is difficult, equipment is spread across several buildings, work must be coordinated around teaching, clinical care or customer activity, or the site has strict security controls.
The assessment should be communicated to the people doing the work. It is of limited value if it remains in an office folder while an engineer faces a situation that was not explained to them. Briefings should cover the controls, site contacts, emergency actions and the point at which work must stop and be reassessed.
Managing common risks during compliance visits
Low-disruption work still requires active control. During portable appliance testing, test leads and equipment should not create a trip hazard in corridors, walkways or busy rooms. Engineers may need to work in sections, use warning signs, move leads frequently, or arrange testing at quieter times. Equipment should only be disconnected with the agreement of the person responsible for it, especially where it supports IT systems, care equipment or essential operations.
Fire safety servicing and inspection work requires similar care. Escape routes should remain available, and any temporary removal of a fire extinguisher should be managed so that appropriate fire protection is maintained. If an issue is found that could affect life safety, it should be reported promptly to the responsible person with clear advice on the immediate action required.
Work at height is another area where assumptions can cause problems. Reaching appliances, detectors or door components positioned above normal working height may require appropriate access equipment. Chairs, desks and improvised furniture are not acceptable substitutes. The method should be agreed in advance where possible, especially in confined areas or locations open to the public.
When the assessment needs to change
Risk assessment is an ongoing process, not a one-off approval. Conditions can change between booking and arrival, or while work is underway. A corridor may become busy, a room may be occupied unexpectedly, a fire alarm test may be planned, or an engineer may discover damaged equipment or restricted access that was not anticipated.
In these situations, the right response is to pause, review the risk and agree a safe alternative. That might mean rescheduling part of the work, isolating an area, changing the order of tasks or involving the site manager. Pressing on simply to complete the job can create unnecessary risk and undermine the purpose of the assessment.
The assessment should also be reviewed after incidents, near misses, significant changes to the site, changes to the scope of work, or where the same task has repeatedly caused disruption. Lessons from one visit can make future visits quicker, safer and easier to manage.
Choosing a contractor who plans properly
Price matters, but it should not be the only consideration when appointing a safety compliance provider. Ask how the contractor assesses site-specific risks, whether their engineers hold relevant qualifications, how they manage safeguarding requirements, and what information they need from you before attending. For work in schools, care settings and other sensitive environments, DBS-cleared personnel may also be an essential requirement.
Look for a provider that can explain its process in plain language. You should know who will attend, what work will be completed, how disruption will be controlled and what happens if a safety issue is identified. Competence is demonstrated through preparation and professional conduct as much as through certificates.
Janus Safety Solutions plans each visit around the client’s premises and operational needs. Where required with a booked job, a free health and safety risk assessment helps clients prepare for PAT testing and fire safety services with minimal interruption to normal activity.
A well-planned contractor visit should leave more than test labels, service records or inspection findings. It should leave the site confident that the work was completed with proper care for the people who use the building every day.
