In today’s digital-first world, protecting customer and employee data isn’t just about good practice—it’s a legal obligation. With regulators clamping down and public trust on the line, businesses across the UK are under more pressure than ever to get data protection right.
And yet, mistakes continue to happen. Some are due to outdated systems, others to a lack of awareness or training. Whatever the cause, the consequences can be severe—from fines and reputational damage to loss of business and legal claims.
In this blog post, we’ll explore five of the most common data protection pitfalls still catching businesses out, and how to avoid them. Organisations seeking robust support can turn to data protection solicitors in Scotland for tailored guidance aligned to local legal expectations.
1. Assuming GDPR Doesn’t Apply to You
One of the most damaging assumptions businesses make is believing that data protection laws don’t really apply to them. Whether you’re a small café collecting email addresses for a newsletter or a medium-sized enterprise managing payroll data, if you’re handling personal data, the General Data Protection Regulation (GDPR) applies.
GDPR doesn’t just affect tech giants. It governs any organisation processing data about identifiable individuals. That includes names, addresses, medical details, job titles, or even IP addresses.
The UK’s Information Commissioner’s Office (ICO) regularly publishes enforcement action against small businesses—not just large corporations. If you’re unsure whether your policies and practices are compliant, now’s the time to get clarity.
2. Not Training Staff Properly
Human error remains one of the biggest causes of data breaches in the UK. From emails sent to the wrong recipient to weak passwords and poor access control, employees are often the weakest link in your cyber defences.
Yet, many businesses fail to provide meaningful data protection training. It’s not enough to mention GDPR during onboarding and hope it sticks. Regular, role-specific training should be a key part of your compliance plan.
The National Cyber Security Centre (NCSC) offers practical guidance for small businesses on how to boost staff awareness around cybersecurity and data handling. Creating a culture where employees understand their responsibilities can drastically reduce your risk.
3. Inadequate Record-Keeping
GDPR requires organisations to demonstrate compliance, not just claim it. That means keeping detailed records of how you collect, process, store, and share personal data. Many businesses wrongly believe that if no complaints have been made, they must be compliant. Unfortunately, the absence of a data breach doesn’t mean you’re off the hook.
The ICO recommends having clear documentation that outlines:
- What personal data you hold
- Where it came from
- Who you share it with
- How long you keep it
Without these records, you’ll struggle to prove due diligence if an investigation arises. Using GDPR templates or working with a specialist advisor can help build a defensible audit trail.
You can also refer to the ICO’s Record of Processing Activities guidance, which is especially useful for SMEs needing clarity on documentation requirements.
4. Failing to Respond to Subject Access Requests (SARs)
Under data protection laws, individuals have the right to access the personal data you hold about them. These are known as Subject Access Requests (SARs). You must respond within one calendar month, and the information must be provided free of charge in most cases.
Failing to recognise or respond to a SAR is one of the most common causes of ICO complaints. In fact, SAR mishandling is consistently among the top reasons for regulatory action.
What makes this worse is that many SARs come from disgruntled employees or customers—precisely when your relationship is already strained. Having a clear internal process for handling SARs is essential. This should include assigning responsibility, setting deadlines, and using secure methods for data sharing.
5. Ignoring Third-Party Risks
It’s not just what you do with personal data that matters—it’s what your suppliers and partners do too. If you share personal data with third-party processors (like cloud storage providers, payroll companies, or outsourced marketing agencies), you must ensure they meet GDPR standards.
Failing to vet third-party contracts and security measures is a ticking time bomb. If your partner experiences a breach or misuses data, your business could still be held liable.
Make sure all contracts contain adequate data processing clauses, and conduct regular reviews of your suppliers’ data handling practices. This is especially important for businesses working in regulated sectors or handling sensitive categories of data.
Bonus: Overlooking Privacy by Design
Another common oversight is failing to build privacy into products, services, or systems from the outset. GDPR promotes the principle of “privacy by design and default”—meaning data protection should be embedded into every aspect of your operations.
This includes:
- Minimising data collection
- Ensuring default settings prioritise privacy
- Making it easy for users to opt in or out
- Protecting data through encryption and access controls
For example, if you’re launching a new app or service, it should be designed to collect only the data necessary for its function—and nothing more.
Why It Pays to Stay Compliant
Aside from avoiding legal penalties, good data protection practices are simply good business. They foster trust with customers, improve operational transparency, and reduce the likelihood of disruptive breaches.
According to Cyber Essentials, even basic cyber hygiene can prevent the majority of attacks. By combining technical defences with legal compliance and staff training, your business becomes significantly more resilient.
Get Ahead of the Risk
Data protection isn’t a tick-box exercise—it’s a continuous process. With regulations evolving and threats becoming more sophisticated, businesses must stay proactive, not reactive.
The good news is that with the right systems, training, and legal support, compliance is entirely achievable. Don’t wait for a breach or complaint to take action. Start reviewing your practices today—and futureproof your business for the long term.
