Understanding CSRD assurance costs and compliance timelines

Assurance costs: Initial and ongoing impacts

CSRD introduces substantial costs at every stage of compliance, with both one-time setup and annual recurring costs:

• One-off setup costs: Large, publicly listed companies—especially those previously under the Non-Financial Reporting Directive (NFRD)—face average initial costs of EUR 287,000 to establish systems for capturing and reporting on CSRD’s expanded ESG data requirements. Smaller companies incur lower setup costs due to simpler reporting structures, though these costs still represent a significant budget item.
• Annual recurring costs: Ongoing assurance costs average EUR 320,000 annually for NFRD-listed companies, driven by verification and reporting activities. Costs scale with company size, complexity, and sector, with financial institutions and large manufacturers facing the highest expenses.
• Potential cost increases down the line: The European Commission is also required to adopt reasonable assurance standards by 1 October 2028, following an assessment to determine if such a transition is feasible for both auditors and companies. The directive does not specify an exact date for when companies must comply with reasonable assurance requirements, but this will be determined based on the EC’s assessment and subsequent decisions.

Long-term savings through strategic assurance cost management

The shift from limited to reasonable assurance significantly affects assurance cost structures. Currently, undertakings receiving limited assurance face assurance costs of about 20% to 30% of their average financial assurance costs. As the CSRD progresses to reasonable assurance by 2028, this range is expected to increase, though.

This shift represents a major uptick in both time and resources required to meet compliance standards, making efficient, cost-effective solutions increasingly essential for controlling long-term expenses.Another key factor to consider is the difference between first-time (one-off) assurance costs and ongoing (recurring) assurance costs.

According to assurance providers consulted for the CSRD cost-benefit analysis, one-off assurance costs are approximately 30% higher than ongoing costs. This initial spike is due to the need for substantial setup efforts—creating systems, establishing protocols, and familiarising assurance providers with company-specific data.

As ongoing costs become the primary expense, companies that have already invested in robust data management and automation will be in a stronger position to manage recurring costs effectively.

CSRD compliance timeline

The CSRD rolls out in structured phases, increasing compliance demands year by year:

Financial implications for strategic leadership

These compliance requirements bring direct financial and strategic implications that CFOs cannot afford to overlook. They impact budgets, financial planning, investor relations, and competitive positioning. Here’s why understanding and managing these costs is essential for strategic financial leadership:

• 1. Budget forecasting and cost management: With one-off setup expenses reaching EUR 287,000 for large companies and ongoing assurance costs around EUR 320,000 annually, CFOs must account for these figures in forecasts. As reporting demands increase, proactive management of assurance costs becomes critical to avoid unanticipated budget strains.
• 2. Investment appeal: ESG performance is a key metric for investors. Transparent, verifiable ESG data strengthens investor confidence, potentially lowering the cost of capital and attracting sustainability-focused funding. Robust compliance bolsters investor trust, positioning companies as responsible, reliable investments.
• 3. Operational efficiency and risk management: Automating compliance processes reduces costs and minimises compliance risk. Effective data centralisation and automation streamline reporting, cut down on redundant work, and prevent costly errors. This enhances operational efficiency while keeping the company prepared for stringent reasonable assurance standards expected by 2028.
• 4. Strategic advantage in the market: As competitors navigate the same CSRD challenges, companies with efficient, integrated compliance systems gain a clear edge. Strong, verified ESG reporting differentiates businesses in the eyes of both customers and investors, establishing a competitive advantage through transparency and reliability.

Streamlining compliance to manage costs and ensure efficiency

Effectively managing assurance costs while keeping pace with the compliance timeline requires streamlined data processes. By centralising ESG data, automating compliance checks, and ensuring audit readiness, companies can minimise their reliance on costly external consultants and reduce time-consuming manual efforts.

Integrated ESG management systems offer a cost-effective approach, consolidating data in a single platform, ensuring traceable and audit-ready reporting, and reducing the workload on internal teams.
