Monthly Site Audit Report

The Monthly Site Audit Report provides a comprehensive review of health and safety performance across the project, scoring compliance against key indicators and identifying trends. It covers documentation checks, behavioural observations, subcontractor performance, and statutory compliance. The audit generates a scored report with photographic evidence and an action plan for the following period.

Last reviewed: 29 March 2026 — This guide reflects UK law as of this date. CDM 2015 / MHSWR remains current with no amendments enacted as of 29 March 2026. Next scheduled review: 29 March 2027.

1. The Audit — Looking at the System, Not Just the Site

The monthly audit operates at a different level from the weekly inspection. Where the inspection asks 'is the scaffold guardrail in place today?', the audit asks 'is the system for inspecting, certifying, and maintaining scaffolding working reliably?' It looks at management systems — the processes, records, and behaviours that determine whether a site is consistently safe or only safe when watched.

The audit catches deteriorating compliance that inspection alone may not detect. A weekly inspection may find the guardrail in place every Friday, but the audit may reveal that scaffold inspection records have not been completed for three weeks — indicating a system failure that will eventually produce a physical one.

Score each area consistently — audit reports gain value through trend comparison

If the monthly audit scores each area on a consistent scale (0-3), scores can be compared month-to-month and area-to-area. Declining scores indicate deteriorating management before incidents occur. Improving scores confirm that interventions are working. A series of monthly reports with trend data is genuinely powerful evidence of active management.

2. Areas to Audit

Area	Questions
CPP implementation	Is the CPP current, site-specific, and being followed? Are amendments documented?
Induction compliance	Are all workers in the register? Are records complete? Have any uninducted workers been found on site?
PTW compliance	Are permits issued, monitored, and closed correctly? Any self-issue? Any unclosed permits?
RAMS compliance	Are task RAMS in place for all activities? Have they been briefed to workers? Are workers following the methods described?
Weekly inspection	Is the inspection being completed every week? Are actions from previous weeks closed?
Welfare standards	Are facilities maintained in clean, operational condition? Is provision adequate for the workforce?
Training records	Are toolbox talk records maintained? Have skill gaps been identified and addressed?
Subcontractor management	Are subcontractors providing their own RAMS and complying with site rules? Is persistent non-compliance being addressed?
Incident management	Are all incidents and near misses reported? Have root cause analyses been completed?
Legal compliance	Are LOLER certs current? LEV 14-month exams current? Plant PUWER inspections completed? F10 displayed?

3. Common Mistakes

Monthly audit conducted as a version of the weekly inspection

The audit must look beyond physical conditions to examine management systems. The questions should be "show me the last three weeks of inspection records" not "let me check the guardrail."

Audit conducted by site manager — no independent perspective

The audit is most valuable when conducted by an independent H&S advisor, contracts manager, or external consultant. Independence gives the findings credibility and avoids blind spots.

Audit actions not tracked to resolution

The audit must begin by reviewing the previous month's actions. If October actions are still open in December, that is a management failure requiring escalation.

Reports not shared with senior management

The audit report must be reviewed by the contracts director or operations manager. This ensures systemic issues receive appropriate resource. A report staying in the site office file does not fulfil the MHSWR Reg 5 function.

No positive recognition — audit only identifies failures

An effective audit identifies both good practice and areas for improvement. Recognising excellent management reinforces positive behaviour and creates a balanced record that demonstrates genuine engagement.

4. Frequently Asked Questions

What is the difference between an inspection and an audit?▾

An inspection checks conditions at a point in time (physical measures). An audit examines the management system (whether processes are working). Both are needed — the inspection provides operational monitoring; the audit provides management system assurance.

How formal does the audit need to be?▾

Proportionate to the project. Small project: a structured conversation documented in a brief summary. Large project: a standardised checklist, consistent scoring, and a formal written report. The key requirements are: competent person, coverage of management systems, written record, and actions tracked.

Can the audit be conducted remotely?▾

Some elements can be reviewed remotely (records review, document completeness). But the audit must include physical site presence to observe conditions, interview site management, and verify that physical conditions match the documentary record. A purely remote audit cannot fulfil MHSWR Reg 5.

Should audits be announced or unannounced?▾

Both have value. Announced audits allow preparation and test the normal state. Unannounced audits reveal true day-to-day conditions. A mixture of both gives the most complete picture. Senior management walkrounds complement the formal audit programme.
