Construction Site Inspection Checklist UK (2026 Guide)

At a glance

• Scaffolding / working platforms above 2m: inspected before first use, after any event affecting stability, and at intervals not exceeding 7 days — Work at Height Regulations 2005.
• Excavations with supports or battering: inspected by a competent person at the start of every shift, with one written report needed per 7-day period unless conditions change — CDM 2015, regulation 22.
• Lifting equipment (LOLER): thorough examination every 6 months if used to lift people, every 12 months otherwise, unless an examination scheme sets different intervals.
• Work equipment and plant (PUWER): inspected after installation and before first use, then at suitable intervals where conditions could cause deterioration.
• Welfare facilities: Schedule 2 of CDM 2015 sets the minimum — sanitary conveniences, washing facilities, drinking water, changing rooms/lockers, and rest facilities.
• Noise: risk assessment required once exposure reaches 80 dB(A); hearing protection mandatory once exposure reaches 85 dB(A) — Control of Noise at Work Regulations 2005.
• Hand-arm vibration: exposure action value of 2.5 m/s² A(8) triggers a duty to introduce controls — Control of Vibration at Work Regulations 2005.
• Enforcement: HSE can serve an improvement notice (section 21) or a prohibition notice (section 22) under the Health and Safety at Work etc. Act 1974, and recover costs through Fee for Intervention where it finds a material breach.
• Fatalities: construction had 35 worker deaths in 2024/25 — more than any other UK industry — with falls from height the leading cause. Source: HSE.

What a site inspection checklist is for

A construction site inspection checklist is a structured document used to walk a site, examine each key risk area, and record whether the controls that should be there are actually in place and working. It is not itself a legal form, but it is one of the main practical ways that employers, principal contractors and principal designers demonstrate they are meeting their duties under the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999, and the Construction (Design and Management) Regulations 2015 (CDM 2015).

A thorough inspection typically covers access and site security, traffic management, welfare provision, manual handling, lifting operations, electrical safety, work at height, personal protective equipment, and exposure to hazards such as dust, noise and hand-arm vibration. The person carrying it out needs to be competent to recognise the hazards specific to that site — general competence is not enough for specialist checks such as scaffolding or lifting equipment.

The legal duties behind the checklist

General duties under the 1974 Act

Section 2 of the Health and Safety at Work etc. Act 1974 places a duty on every employer to ensure, so far as is reasonably practicable, the health, safety and welfare of employees. Section 3 extends a similar duty to people who are not employees but could be affected by the work — visitors, members of the public, and workers employed by other contractors on a shared site. A regular, recorded inspection regime is one of the clearest ways to show that duty is being actively discharged, rather than assumed.

CDM 2015: who has to plan, manage and monitor

Under regulation 13 of CDM 2015, the principal contractor must plan, manage and monitor the construction phase and coordinate health and safety matters throughout it, so far as is reasonably practicable. That duty includes ensuring welfare facilities meeting Schedule 2 are provided and maintained for the whole of the construction phase, and coordinating how contractors on site cooperate with each other. On a single-contractor project, the contractor carries the equivalent duties directly. Site inspections are the practical mechanism by which "monitor" gets done — a plan that is never checked against reality is not being monitored.

How often each area must be inspected

Different risk areas sit under different regulations, each with its own inspection regime. This is the most common point of confusion on site — a single "weekly walk-round" is not enough on its own to satisfy every duty.

| Area | Legal trigger | Minimum inspection frequency | |---|---|---| | Scaffolding / working platforms (fall risk over 2m) | Work at Height Regulations 2005 | Before first use, after any event affecting stability, and at least every 7 days | | Excavations with supports or battering | CDM 2015, regulation 22 | Start of every shift; one written report per 7-day period unless conditions change | | Lifting equipment used to lift people (e.g. passenger hoists) | LOLER 1998, regulation 9 | Every 6 months, unless an examination scheme states otherwise | | Other lifting equipment (e.g. cranes, lifting accessories) | LOLER 1998, regulation 9 | Every 12 months, unless an examination scheme states otherwise | | General work equipment and plant | PUWER 1998, regulation 6 | After installation/before first use, then at suitable intervals judged by exposure to deterioration | | Whole-site walk-round (access, welfare, housekeeping, PPE) | General duties under HSWA 1974 and CDM 2015 | No fixed statutory frequency — weekly is a common benchmark on active sites |

Step-by-step: running the inspection

1. Plan the inspection before you walk the site. Decide who is carrying it out, which areas and activities will be covered, and which standard you are measuring against. Review the construction phase plan, any recent incident reports, and outstanding actions from the previous inspection so you know what to prioritise.
2. Check access, egress and site security. Walk the perimeter and entry points. Confirm hoarding and fencing are intact, gates are controlled, and there are clear, safe routes for workers and visitors. Check signage, segregation between pedestrians and vehicles, and whether the site is secure against unauthorised access — particularly important where the public, including children, could get near the boundary.
3. Inspect work at height and lifting operations. Examine scaffolds, edge protection, ladders, mobile access platforms and any openings in floors or roofs. Confirm scaffold inspection records are current and signed off by a competent person, at intervals no longer than 7 days. For lifting equipment, confirm thorough examinations are in date under LOLER and that operators hold the relevant certification.
4. Check excavations at the start of every shift. If supports or battering are in use, a competent person must inspect before work resumes each shift, and after any event — heavy rain, nearby vibration, a fall of material — that could have affected stability. Do not allow work to continue in an excavation the inspector is not satisfied with.
5. Review welfare, housekeeping and PPE. Good welfare facilities and a tidy site are strong indicators of overall safety culture. Check toilets, washing facilities, drinking water, changing rooms and rest areas meet Schedule 2 of CDM 2015. Look at how materials are stored, whether walkways are clear, and whether operatives are wearing the head, eye, hand, foot and high-visibility protection appropriate to the task.
6. Check controls for dust, noise and vibration. Confirm on-tool extraction and water suppression are actually connected and running, not just present. Where daily noise exposure could approach 80 dB(A), check hearing protection is available and used above 85 dB(A). Where hand-held vibrating tools are in regular use, check job rotation and exposure monitoring against the 2.5 m/s² A(8) action value.
7. Record findings and assign actions. Write up what you saw, using photographs where helpful, and complete a written report where one is legally required — for Work at Height Regulations inspections, this must be prepared before the end of the working period and provided within 24 hours. Rank issues by severity, allocate each action to a named person with a realistic deadline, and feed serious concerns straight back into the construction phase plan. Close out previous actions before opening new ones so nothing drifts.

Recording findings and keeping evidence

Some inspections carry a specific statutory reporting duty; others do not, but a good record is worth keeping regardless.

• Work at height: Schedule 7 of the Work at Height Regulations 2005 sets out exactly what a written report must contain — who it was carried out for, the location and description of the equipment, the date and time, the inspector's name and position, any risk-giving matter found, and any action taken or still needed. The employer must keep that report at the site until the construction work is completed.
• Excavations: only one written report is needed per 7-day period under CDM 2015, unless conditions change or an additional inspection is triggered — but if the inspector is not satisfied, work must stop in that excavation until the issue is resolved.
• Lifting equipment: LOLER thorough examinations must be reported in writing by the competent person carrying them out, and those reports should be retained as evidence the examination regime is being followed.
• General site inspections: there is no single statutory format, but a dated, photographed, action-tracked record is what demonstrates "monitoring" under CDM 2015, regulation 13, and is what an HSE inspector or a court will expect to see if something goes wrong later.

What happens if the HSE finds a problem

HSE inspectors visiting a site can give advice on the spot, or take formal enforcement action. An improvement notice under section 21 of the Health and Safety at Work etc. Act 1974 requires a specified breach to be put right within a set period. A prohibition notice under section 22 stops an activity that involves, or will involve, a risk of serious personal injury — immediately, if the inspector judges the risk to be imminent. Persistent or serious breaches can lead to prosecution.

Where HSE identifies a material breach of health and safety law during an intervention, it can also recover its costs from the dutyholder through Fee for Intervention, charged at an hourly rate that HSE reviews and republishes periodically — always check the current rate on GOV.UK rather than relying on a figure quoted elsewhere, as it changes. A tight, genuinely followed inspection regime — not just a checklist filed away unread — is the most reliable way to avoid reaching any of these outcomes.
