Compliance in 2025: why it matters for UK business leaders

TL;DR:

• Compliance in 2025 became a strategic license to operate, directly safeguarding business value and boosting deals. UK regulators increased oversight, with HMRC collecting over £9 billion in compliance yield and enforcement actions intensifying across agencies. Firms must proactively map obligations, leverage automation, and prioritize continuous testing to manage regulatory risk effectively.

Compliance in 2025 was not a back-office obligation for UK organisations — it was a strategic licence to operate that directly protected business value, accelerated commercial deals, and reduced the cost of capital. PwC’s Global Compliance Survey found that compliance leaders are increasingly influential in strategic decisions, with many firms now expecting compliance functions to inform product design and market entry, not just reporting. HMRC’s Wealthy and Mid-sized Business Compliance Directorate generated £9.147 billion in compliance yield in 2024–25, a figure that signals exactly how seriously the regulator is pursuing gaps. The single most important action you can take right now: map your obligations across HMRC, the FCA, and the ICO, then assess where your evidence trails are weakest.

• Licence to operate: Compliance failures block financing, procurement, and M&A.
• Enforcement is real: HMRC collected £9.147 billion in compliance yield in 2024–25.
• Regulators are proactive: The FCA, ICO, and HMRC all increased supervisory activity in 2025.
• Technology is shifting the baseline: AI and automation are raising what “good” looks like.
• SMEs are most exposed: Reactive postures leave persistent blind spots that cost more to fix later.

Why did compliance become a business priority in 2026?

The commercial case for compliance has never been cleaner. Organisations that embed compliance into strategy report faster sales cycles, smoother due diligence, and stronger investor confidence — not as soft benefits, but as measurable commercial outcomes. A buyer conducting due diligence on a potential acquisition or supplier will walk away from a firm with unresolved regulatory exposure before they negotiate price. That is a deal-killer that no amount of goodwill recovers.

KPMG links compliance and ESG strength to improved financing terms and valuation prospects. In practice, this means a well-governed business can access capital at a lower cost and on better conditions than a comparable firm with a patchy compliance record. Insurers apply the same logic: a documented, tested compliance programme reduces premium risk, and underwriters increasingly ask for evidence of it.

Enforcement trends made the urgency sharper. HMRC’s compliance yield in 2024–25 covered Corporation Tax, Income Tax, VAT, and a range of other interventions. The ICO continued to pursue data protection breaches with material fines, and cumulative EU GDPR fines exceeded €5 billion by end of 2024, a signal of the direction of travel for UK enforcement too. The FCA intensified supervisory engagement across financial services, with a clear shift from reactive investigation to proactive thematic review.

What changed in the UK regulatory landscape in 2026?

Several rule changes came into force or accelerated during 2025, and compliance teams needed to track each one.

Key regulators and rule areas:

• FCA: Intensified Consumer Duty implementation reviews, with firms expected to evidence outcomes rather than just policies. Thematic supervisory work covered operational resilience, financial promotions, and appointed representative oversight.
• ICO: Continued enforcement under UK GDPR, with a focus on data minimisation, legitimate interest assessments, and AI-related data processing. The ICO’s enforcement approach became more proactive, targeting systemic failures rather than isolated incidents.
• HMRC: Expanded use of data analytics to identify risk, particularly in R&D tax credit claims, employment status, and VAT. The Wealthy and Mid-sized Business Compliance Directorate’s £9.147 billion yield in 2024–25 reflects the breadth of that reach.
• Companies House: From 18 November 2025, identity verification became compulsory for new directors and people with significant control (PSCs) at incorporation. Companies House estimates 6–7 million individuals will need to verify by mid-November 2026. Acting as a director without verification is a criminal offence once the duty applies.
• Payment practices reporting: From 6 April 2025, updated thresholds apply: £54 million annual turnover, £27 million balance sheet total, and 250 employees. Businesses meeting two of three criteria must report half-yearly. Failure to publish is a criminal offence for the business and every director.
• ESG reporting: Mandatory climate-related financial disclosures expanded in scope, and the FCA’s sustainability disclosure requirements created new obligations for asset managers and listed companies.

Post-Brexit divergence is a live issue for any UK firm operating in the EU. UK GDPR and EU GDPR have diverged in interpretation and enforcement approach. UK firms transferring personal data to the EU must maintain valid transfer mechanisms, and the adequacy decision underpinning those transfers is subject to periodic review. For firms with EU customers or operations, tracking both regimes is not optional.

Near-term watchlist for 2025–26:

• Companies House identity verification phased rollout completing by November 2026.
• ICO guidance on AI and automated decision-making.
• HMRC’s Making Tax Digital expansion to further taxpayer categories.
• FCA Consumer Duty outcome testing and enforcement action.
• Construction sector payment retention reporting from April 2025.

How did AI, analytics, and RegTech reshape compliance in 2026?

The practical gains from automation are real. SureCloud’s Risk Reckoning 2025 found that AI-driven automation reduces manual evidence collection and speeds up control monitoring — but also that many organisations still rely on spreadsheets, leaving persistent gaps between aspiration and actual capability. Moving evidence collection to integrated tools gives real-time visibility of control status that a spreadsheet simply cannot replicate.

For compliance leaders, the technology opportunity is in three areas: continuous monitoring (replacing point-in-time testing), automated evidence collection (cutting the manual burden of audit preparation), and analytics-driven risk identification (spotting anomalies before regulators do). These are not theoretical gains. Firms that have adopted integrated GRC platforms report materially shorter audit cycles and fewer surprises at year-end.

The risks are equally concrete. AI models can produce plausible but incorrect outputs — a particular problem in regulatory interpretation. Data fed into third-party AI tools may create confidentiality or data protection obligations. And governance of AI-generated outputs is itself a compliance question: who is accountable when the model is wrong?

Technology evaluation checklist for compliance leaders:

• Data readiness: Is your underlying data clean, structured, and accessible enough for a tool to act on?
• Governance: Who owns the AI output, and what review process applies before it is acted upon?
• Integration: Does the tool connect to your existing systems, or does it create a new data silo?
• Vendor risk: Has the vendor been assessed for data security, sub-processor arrangements, and financial stability?
• Regulatory alignment: Does the tool’s output meet the evidential standards your regulators expect?

Pro Tip: Start with a single, well-scoped use case — automated evidence collection for one control domain, for example — before expanding. A staged adoption lets you validate outputs against known results before relying on the tool for live regulatory submissions. See also the accounting trends shaping UK firms for a broader view of where automation is heading.

What should compliance leaders prioritise first in 2026?

A prioritisation matrix cuts through the noise. The actions below are sequenced by urgency, not importance — all of them matter, but some cannot wait.

Immediate (0–3 months):

• Map all regulatory obligations across HMRC, FCA, ICO, and Companies House. Gaps you cannot see cannot be managed.
• Verify that all directors and PSCs are on track for Companies House identity verification before their confirmation statement deadline.
• Review R&D tax credit claims and employment status positions if HMRC has not already been in contact — these are active risk areas.
• Confirm data transfer mechanisms for any EU personal data flows are current and documented.

Short-term (3–9 months):

• Implement or upgrade automated evidence collection for your highest-risk control areas.
• Conduct a supplier and vendor compliance review, including AML checks where relevant. AML policy frameworks are a useful reference point for structuring this.
• Deliver role-based compliance training, not generic awareness sessions. The FCA and ICO both look for evidence that staff in specific roles understand their specific obligations.
• Establish a board compliance reporting cadence: quarterly at minimum, with a clear risk appetite statement signed off at board level.

Strategic (9–18 months):

• Build a continuous testing programme. UK Finance’s OpRes findings are clear: static documentation is not resilience. Regular exercises, including supplier testing, are what separate firms that pass audits from firms that actually manage risk.
• Develop a compliance maturity roadmap that ties investment to measurable risk reduction, not just activity.
• Review your governance structure: does the compliance function have direct board access, and is the risk appetite formally documented and reviewed annually?

Quarter-by-quarter execution:

• Q1: Obligation mapping, identity verification audit, data transfer review.
• Q2: Vendor checks, training delivery, board reporting framework.
• Q3: Automated evidence tools live for priority controls, near-miss reporting embedded.
• Q4: Full compliance maturity assessment, roadmap for the following year.

How do you measure the return on compliance investments?

The business case for compliance spend is easier to build than most finance directors expect. The value levers are concrete: avoided fines, faster sales cycles, lower insurance premiums, and reduced incident response costs. The challenge is capturing them in a format that speaks to a board or CFO.

Building a short business-case model is straightforward: estimate the probability and cost of the top three regulatory risks without the programme, subtract the cost of the programme, and add the commercial benefits (faster onboarding, lower insurance, reduced audit cost). KPMG’s analysis of compliance and ESG strength improving financing terms gives you an additional lever if your firm is seeking external capital.

Pro Tip: Near-miss data is your most powerful leading indicator. A control that catches a near-miss is working; a control that never triggers is either perfect or invisible. Track near-misses monthly and use them as evidence in board reports — regulators and auditors respond well to a firm that demonstrates it learns from close calls rather than waiting for incidents.

How should UK SMEs act on compliance in 2026?

SMEs face the same regulatory obligations as larger firms, with a fraction of the resource. SureCloud’s data shows many SMBs only modernise their compliance approach after an incident — a reactive posture that costs significantly more to fix than a proactive one. The checklist below covers the essentials.

SME compliance checklist:

• Keep financial records for a minimum of six years, as required by HMRC.
• File VAT returns on time and reconcile quarterly; errors in VAT are one of HMRC’s highest-yield investigation areas.
• Run PAYE correctly and on time; employment status misclassification is an active HMRC risk.
• Register with the ICO if you process personal data (most businesses do), and document your lawful basis for each processing activity.
• Implement basic GDPR controls: a privacy notice, a data retention policy, and a process for handling subject access requests.
• Complete AML due diligence if your business falls within regulated sectors (accountancy, legal, estate agency, financial services).
• Verify director and PSC identities with Companies House ahead of your next confirmation statement.
• Conduct a quarterly compliance review to catch missed deadlines before they become penalties.

Practical steps for outsourcing compliance support:

1. Identify which obligations you cannot manage reliably in-house (payroll, VAT, statutory accounts).
2. Engage a qualified accountancy firm with demonstrable HMRC and ICO compliance experience.
3. Agree a documented compliance programme with quarterly review points.
4. Retain oversight: outsourcing reduces operational risk, but liability for compliance failures stays with the business owner.
5. Use software that integrates with your accountant’s systems to give real-time visibility of your financial position.

What do the 2025 surveys and reports actually say?

The evidence base for the importance of compliance in 2025 is solid, and the key findings point in the same direction.

A note on methodology: The PwC and SureCloud surveys are self-reported, which means responses reflect perception of compliance maturity rather than independently verified capability. HMRC’s yield figures are audited and published in the Annual Report and Accounts, making them the most reliable quantitative benchmark. KPMG’s analysis draws on advisory engagement data rather than a formal survey sample. Readers should treat survey findings as directional rather than definitive, and cross-reference with their own regulatory correspondence and audit outcomes.

How has UK data protection law changed since the GDPR adjustment?

The UK retained the GDPR framework after Brexit but has since developed its own interpretation through ICO guidance and the Data Protection and Digital Information Act (DPDIA) process. The result is a regime that is broadly compatible with EU GDPR but diverges in several practical areas.

The ICO has taken a more outcomes-focused enforcement approach than some EU supervisory authorities, emphasising accountability and documented decision-making over procedural box-ticking. For UK firms, this means the quality of your data protection impact assessments (DPIAs) and legitimate interest assessments matters more than their existence alone. An ICO investigation will look at whether your reasoning was sound, not just whether the document exists.

For firms operating across both UK and EU markets, the divergence creates a genuine compliance overhead. UK GDPR and EU GDPR share the same structure but differ in detail — particularly around international data transfers, where the UK’s adequacy decisions and standard contractual clauses have developed separately. Firms should maintain separate compliance documentation for each regime rather than assuming one set of policies covers both.

AI and automated decision-making is the area where UK data protection law is evolving fastest. The ICO has published guidance on AI and data protection, and the DPDIA process has introduced provisions around automated decisions that differ from Article 22 of EU GDPR. Any firm using AI tools that process personal data needs to assess those tools against the current ICO guidance, not just the original GDPR text.

How do you future-proof your compliance programme beyond 2026?

Legislation does not stand still, and the firms that manage compliance well are the ones that treat it as a forward-looking capability rather than a retrospective exercise. Several developments are already in motion that will shape compliance obligations through 2027 and beyond.

Making Tax Digital is expanding. HMRC’s phased rollout will bring more businesses into mandatory digital record-keeping and quarterly reporting, and the timeline is firm. Firms that have not yet adopted compatible software will face a harder transition the longer they wait.

The Companies House identity verification rollout continues through November 2026, with corporate directors, LLP members, and officers of corporate PSCs coming into scope in later phases. The Economic Crime and Corporate Transparency Act 2023 gives Companies House significantly expanded powers to query, reject, and investigate filings — a material change from the previous register-and-file model.

ESG reporting obligations are broadening. The FCA’s sustainability disclosure requirements are already in force for asset managers, and the direction of travel for larger corporates and their supply chains is clear. Firms that build ESG data collection and reporting capability now will be ahead of mandatory requirements rather than scrambling to catch up.

The practical approach to future-proofing is straightforward: assign a named owner for regulatory horizon scanning, review the forward legislative calendar quarterly, and build flexibility into your compliance programme so that new obligations can be absorbed without a complete rebuild. A well-structured accounting compliance framework gives you the foundation to add new requirements without starting from scratch each time.

Key takeaways

Compliance in 2025 was a direct commercial asset for UK businesses: firms with mature compliance programmes secured better financing, closed deals faster, and avoided the enforcement costs that reactive organisations absorbed.

Compliance advice that actually holds up in practice

The gap I see most often is not between firms that know compliance matters and those that do not. Almost every business leader I speak to understands the regulatory environment is tightening. The gap is between firms that treat compliance as a documented position and those that treat it as a live capability.

A documented position says: “We have a GDPR policy.” A live capability says: “We tested our subject access request process last quarter, found a gap in our third-party processor agreements, and fixed it before the ICO asked.” The first gives you a file to point at. The second gives you a defensible position.

The same logic applies to HMRC. The firms that attract the most scrutiny are not always the ones with the most complex tax affairs — they are the ones whose records are inconsistent, whose VAT reconciliations do not tie, and whose payroll submissions do not match their accounts. HMRC’s analytical tools are sophisticated enough to flag those inconsistencies automatically. The question is whether you find them first.

For SMEs in particular, the resource constraint is real. You cannot hire a full compliance team. What you can do is engage a firm that already knows the terrain — one that handles your payroll, bookkeeping, and tax returns in a way that keeps your records clean and your filings accurate. That is not a luxury. It is the cheapest form of compliance insurance available.
