Firm Metrics July 2025

Firm Metrics overview

Individual audit and SoQM inspection findings are not the only metrics to assess audit quality. The FRC considers other data points, including: the firms' own systems of internal monitoring and their own metrics, as well as monitoring by the ICAEW. For the first time, we have published data on Audit Firm Metrics (formerly Audit Quality Indicators), an initiative voluntarily engaged with the firms. This data is intended to inform and stimulate meaningful conversations between the firms and audit committees about how quality is defined and managed by a firm.

Firm metrics should enhance transparency about, and provide deeper insight into, some factors related to performance of audit firms. These metrics provide easy to use, consistent, and comparable information about various aspects of audit firm performance.

In addition to Audit Quality Review (AQR) and Recognised Supervisory Body (RSB) inspection results, these metrics provide information on further aspects of the firms' performance including audit firm culture, internal inspection results, staff workload, and partner involvement. This provides a holistic view across the firms, and offering users of audit services, including audit committees and investors, a more comprehensive understanding of larger audit firms' performance.

We recognise that these metrics are not formulaically or mechanistically linked to audit quality. However, when used effectively, they can prompt valuable discussions between Audit Committee Chairs (ACCs) and firms about factors affecting audit quality, broadening ACCs' perspectives when recommending external auditors to boards or assessing the performance of their existing auditor. This supports the functioning of the audit market as well as the FRC's objective of a more resilient audit market that provides greater choice.

Firm Metrics offer context-specific insights. The significance of particular values for any given metric can vary and should be considered alongside other pieces of information, including their prior-year values. This quantitative data should also be considered in the context of the qualitative aspects of auditing, as outlined in FRC publications such as the "Audit Committee Minimum Standard", and "What Makes a Good Audit".

All content provided in the report was provided directly by the firms and is unchanged by the FRC. Firms have provided supporting narrative where they wished to add technical context to specific metrics.

Supporting Narrative

BDO

As part of the 2024 BDO UK Audit Quality Survey, the list of possible responses was expanded to include a 5-point Likert scale. The questions and their wording have been unchanged year-on-year.

Crowe

These are based on firmwide survey results from 2024. The questions asked were identical to the FRC's proposed wording and were asked of partners and staff in the audit practice only.

Deloitte

For 2025 (and going forward), Deloitte will use a 5-point scale to measure survey outcomes with 4 and 5 aligned to favourable, 3 being neutral and 1 and 2 being unfavourable. In 2024, an 11 point scale was used with 7-10 being favourable, 5-6 being neutral and 0-4 as unfavourable.

EY

Refer to the EY Audit Quality Report and Transparency Report for details. 2024 survey conducted August - September 2024, 45% response rate.

KPMG

The prior year (September 2023) KPMG survey questions were set before the FRC guidance on questions was available so the closest comparable questions were used.

MHA

MHA uses a 0-10 scale. The following scales were used when categorising the results: Unfavourable (0, 1, 2 & 3); Neutral (4, 5 & 6); Favourable (7, 8, 9 & 10)

PKF

The survey was completed in November/December 2024.

Supporting Narrative

Crowe

This is based on internal file reviews completed in the 9-month period ended 31/03/2025 and the RIs who signed audit opinions in that period. In 2024, Crowe moved its internal quality review period-end date from June to March. As part of this process, a full year's worth of reviews were performed in the 9-month period ended 31/03/2025. The comparatives are for the programme which ran from 1 July 2023 to 30 June 2024.

EY

Includes all RIs who could be expected to sign opinions, including non-UK RIs, not RIs who have signed an opinion.

Forvis Mazars

In addition to internal Quality Monitoring reviews, Forvis Mazars supports newly appointed RIs through a mentorship program, an initiative not reflected in the firm's review metrics. This program serves as an additional quality monitoring measure with a minimum of two files reviewed by an experienced RI mentor.

Grant Thornton

During the year, 79% of RIs at Grant Thornton were subject to an internal review. Of the remainder, 2% were subject to an external review and 14% had only recently been appointed and hence both groups were exempt from an internal review in the year; the remaining 5% were in the process of relinquishing RI status.

KPMG

KPMG RIs are reviewed every 3 years with the number of RIs reviewed adjusted for reviews covered by external inspections and RI resignations/retirements. In the period ended 30 August 2024 there were a number of KPMG RIs who had resigned /retired or were subject to reviews covered by AQR inspections and so the number of RIs reviewed is lower compared to the previous year.

MHA

24 Rls reviewed. 73 Rls signed an audit opinion during the period covered.

PwC

The Responsible Individuals (RIs) in scope of PwC's internal inspections are based on a cyclical policy (see page 64 of the 2024 PwC UK Transparency Report).

BDO

All audits: For the purpose of reporting this metric, only Responsible Individuals (RIs) subject to BDO UK's Practice Review Programme are included in line with the FRC's definition of 'Internal Quality Review'. PIE Audits: The status of audit engagements has been assessed at the end of the review cycle in order to identify whether or not the audit engagement should be classified as a PIE.

Crowe

For each metric, the percentage graded as 1, 2, 3 and 4 respectively are shown. This is based on internal file reviews completed in the 9-month period ended 31/03/2025. In 2024, Crowe moved its internal quality review period-end date from June to March. As part of this process, a full year's worth of reviews were performed in the 9-month period ended 31/03/2025. The comparatives are for the programme which ran from 1 July 2023 to 30 June 2024.

EY

Includes interoffice group audit opinions. EY uses a 3-point scale. PIEs stated are UK PIE companies audited by EY UK from 1 July 2023 to 28 June 2024.

Grant Thornton

At Grant Thornton, we have two internal quality review programmes: National Assurance Review (NAR) covers the whole audit from planning to completion. This includes a review of detailed audit work across a range of areas. Each RI is subject to a NAR at least once every three years, with new Rls being reviewed normally within a year of appointment. An Rl with a file that does not meet the expected standard is subject to review in the subsequent year. During the year, 35% of RIs had a NAR (2023: 35%). Pulse programme which focuses on a number of risk areas of each audit. Any RI who has not been subject to an external or NAR review in any year, receives a Pulse review, with only minimal exceptions approved by the Head of Audit. During the year 44% (2023: 45%) of RIs had a Pulse review. Firm's objective is to ensure that all Rls are subject to a quality review every year.

The PIE listing used for the calculation is the UK PIE listing.

MHA

No PIE engagements were subjected to internal quality monitoring for the prior period. Four PIE engagements were included in the Cold File review process for the current period.

Grant Thornton

At Grant Thornton, there is little seasonality and hence busy period data is similar to the annual data.

KPMG

KPMG total standard contracted hours are a 35 hour week.

PwC

The majority of PwC staff are contracted to a standard working week of 37.5 hours. The average utilisation across all grades equates to an average total working week of 41.6 hours and 44.3 hours in the peak reporting period (January to March).

Supporting Narrative

EY

Includes all individuals who have left EY (including retirements); excludes internal transfers out of the audit practice. Due to the systems in place, it is not practical to split between "qualified, but below manager" and "unqualified". Therefore, this is reported as "senior" and "staff". All "staff" are unqualified. Seniors (including Assistant Managers), include unqualified, part qualified, and qualified.

KPMG

These percentages include staff who have moved from audit to other capabilities within KPMG.

PwC

PwC's average staff attrition was 18%, composed of 16% external attrition and 2% permanent internal transfers.

Supporting Narrative

BDO

Planned mandatory training hours have been calculated with reference to the agreed audit curriculum plan for the period July 2023 - June 2024. Firmwide mandatory training is excluded.

Crowe

The statistics are based on training that forms part of Crowe's mandatory audit training program. Partners and employees completed additional CPD, both mandatory and voluntary, in the period.

EY

Training hours include audit/accounting modules, independence, and role-specific learning. Needs are adapted annually based on regulatory changes, industry developments, technology, economy, environment, etc.

Forvis Mazars

Forvis Mazars has used 31 August as the period end date for both reporting years, serving as the cut-off for the start of any mandatory training courses included in the calculation of average planned hours and for completion rates. Some mandatory on-line training has a completion window straddling the period end date. Training completed after the period end date will show in the firm metrics as incomplete even though it is not overdue.

Grant Thornton

Training hours at Grant Thornton have reduced in 2024, as specific one-off training relating to the introduction of new audit software in the prior year was not repeated in 2024.

Johnston Carmichael

Johnston Carmichael improved its systems for recording and monitoring completions in 2024/25. Introduced new courses for seniors / supervisors in 2024/25. Mandated FRS 102 training for year 2 assistants and above in 2025. The Academy training (assistants to supervisors) is role specific and hence non-linear role progressions may skew year on year comparability.

KPMG

KPMG planned mandatory training hours are based on the minimum mandatory planned training hours applicable to each grade. In addition, staff will be required to do additional mandatory training for particular specialisms and accreditation.

PKF

There is a reduction in the centrally mandated technical training in comparison to the prior year as the 2023/24 year included mandated training for ISA 315 & 240 as well as a wholesale change to PKF's methodology. The 2025 population also includes an increased number of specialists for whom not all such mandated training was relevant to their role.

PwC

Average training hours for unqualified staff increased in 2024 due to the acceleration of training to first year graduates from second/third years, leading to a temporary increase in average training hours. See further details on page 78 of the 2024 PwC UK Transparency Report.

RSM

For qualified and above, the metric is based on average CPD hours per the ICAEW dashboard. RSM has mandatory Audit Quality days (minimum 10 a year) and the approach taken is to mandate the time and not specific courses. For unqualified staff, the mandatory training hours and % completion exclude eLearning modules. The completions rates for previous year were not tracked in sufficient detail to report on this as part of this metric.
