Phishing Awareness: How to Train Your Staff to Spot Scams

Of all the cyber threats facing UK businesses in 2026, phishing remains the most prevalent and the most dangerous. Not because it is technically sophisticated — often it is remarkably simple — but because it targets the one vulnerability that no firewall, antivirus, or encryption can fully protect: human judgement.

Phishing is the practice of sending fraudulent communications — typically emails, but increasingly text messages, phone calls, and social media messages — that appear to come from a trusted source. The goal is to trick the recipient into revealing sensitive information, clicking a malicious link, downloading malware, or transferring money to a fraudulent account.

The UK Government's Cyber Security Breaches Survey consistently identifies phishing as the most common type of cyber attack, affecting 84 per cent of businesses that reported a breach. The NCSC's annual review catalogues thousands of phishing campaigns targeting UK organisations each year. And the financial impact is staggering — UK businesses lost an estimated £2.3 billion to phishing-related fraud in 2025 alone.

The good news is that effective phishing awareness training can dramatically reduce your risk. This guide explains how to build a phishing awareness programme that genuinely changes behaviour and protects your business.

Understanding the Phishing Threat Landscape

Phishing has evolved far beyond the poorly written Nigerian prince emails of two decades ago. Modern phishing attacks are sophisticated, targeted, and increasingly difficult to distinguish from legitimate communications.

Types of Phishing Attacks

Mass phishing is the most common form — generic emails sent to thousands or millions of recipients, impersonating well-known brands like Royal Mail, HMRC, Amazon, or Microsoft. These emails typically create urgency ("Your account has been suspended," "You have an unpaid tax bill") and direct recipients to convincing but fraudulent websites designed to harvest login credentials or payment details.

Spear phishing targets specific individuals or organisations. The attacker researches their target — using LinkedIn, company websites, and social media — to craft a personalised message that is far more convincing than a generic phishing email. A spear phishing email to your finance team might reference a real supplier, a real invoice number, or a real project, making it extremely difficult to identify as fraudulent.

Business Email Compromise (BEC) is the most financially devastating form of phishing. The attacker either compromises a real email account or creates a convincing impersonation to send emails that appear to come from a senior executive, a solicitor, or a supplier. These emails typically request urgent wire transfers, changes to payment details, or sensitive information. BEC attacks have cost UK businesses millions of pounds in individual incidents.

Vishing (voice phishing) uses phone calls instead of emails. A caller impersonating your bank, HMRC, or a technology provider creates urgency and pressures the victim into revealing information or granting remote access to their computer. Smishing uses text messages for the same purpose, often impersonating delivery companies or banks.

QR code phishing (quishing) is an emerging vector that has gained significant traction since 2024. Attackers embed malicious QR codes in emails, PDF attachments, or even physical media such as printed flyers and fake parking notices. When scanned, the QR code directs the victim's mobile device to a phishing website. Because QR codes bypass traditional email link-scanning tools and are typically scanned on personal mobile devices that lack corporate security controls, they represent a significant blind spot for many organisations. The NCSC has issued specific warnings about the rise of QR code phishing targeting UK businesses, noting that many email security gateways cannot inspect QR code destinations the way they scan conventional hyperlinks.

AI-enhanced phishing represents the next evolution of the threat. Attackers now use large language models to generate phishing emails that are grammatically flawless, contextually appropriate, and free of the spelling errors and awkward phrasing that have traditionally been reliable red flags. These tools can also generate convincing deepfake audio for vishing attacks, making it possible to clone a CEO's voice from publicly available recordings and use it to authorise fraudulent transactions over the phone. UK businesses must prepare their staff for a future where the traditional indicators of phishing become increasingly unreliable and where vigilance must extend beyond simply spotting poor grammar.

Why Technical Controls Are Not Enough

Every business should have technical defences against phishing: email filtering to block known malicious messages, link protection to scan URLs in real time, attachment sandboxing to detect malware, and multi-factor authentication to limit the damage if credentials are stolen. These controls are essential and will catch the majority of phishing attempts.

But they will not catch all of them. Attackers constantly evolve their techniques to bypass technical filters. A well-crafted spear phishing email that uses a newly registered domain, contains no attachments or links (just a request to call a phone number or reply with information), and is sent from a compromised legitimate email account will sail past most technical defences. The last line of defence is always the human being reading the email.

This is why phishing awareness training is not optional — it is a critical security control. The NCSC explicitly recommends security awareness training as part of its guidance for UK organisations, and Cyber Essentials assessments evaluate whether staff have been trained to recognise phishing attempts.

Consider the defence-in-depth model: technical controls form the outer layers (email filtering, link protection, endpoint security), but the human layer is the inner defence that catches whatever penetrates the technical barriers. When a novel phishing technique bypasses your email filter — and eventually one will — the difference between a blocked attack and a full-scale breach often comes down to whether the recipient had been trained to pause, evaluate, and report rather than click instinctively. Investing in technical controls without investing in human awareness creates a security posture that is brittle at its core.

Moreover, phishing awareness training delivers benefits beyond direct phishing prevention. Staff who develop the habit of critically evaluating digital communications become more resistant to social engineering in all its forms — phone-based pretexting, physical tailgating, USB drop attacks, and social media manipulation. The critical thinking skills cultivated by good phishing training create a security-conscious workforce that is harder to compromise through any vector, strengthening your organisation's overall resilience against the full spectrum of social engineering threats.

Building an Effective Training Programme

Effective phishing awareness training is not a single annual presentation that staff sit through while checking their phones. Research consistently shows that traditional classroom-style training produces short-term awareness that fades rapidly. Lasting behaviour change requires a sustained, multi-layered approach.

1. Establish a Baseline

Before you begin training, measure your current vulnerability. Send a simulated phishing email to all staff (without warning) and track who clicks the link, who enters credentials, and who reports the email. This baseline measurement tells you how vulnerable your organisation currently is and provides a benchmark against which to measure improvement.

Many UK businesses are shocked by their baseline results. Industry data suggests that in untrained organisations, 20 to 30 per cent of employees will click a phishing link, and 10 to 15 per cent will enter credentials on a fake login page. These numbers represent serious risk.

2. Deliver Initial Training

Your initial training should cover what phishing is and why it matters, the different types of phishing attacks, how to identify suspicious emails (sender address, urgency, links, attachments, requests for information), what to do when you suspect a phishing email (do not click, do not reply, report it), and real-world examples relevant to your industry and business.

Keep the training engaging and practical. Use real examples of phishing emails (redacted as necessary), show side-by-side comparisons of legitimate and phishing emails, and give staff hands-on practice at identifying red flags. Avoid fear-based approaches that make staff anxious about opening any email — the goal is confident, informed decision-making, not paralysis.

3. Regular Simulated Phishing Tests

This is the most effective component of any phishing awareness programme. Send regular simulated phishing emails to your staff — at least monthly — and track the results. Vary the difficulty, style, and approach of the simulations to cover different phishing techniques.

When a staff member clicks a simulated phishing link, they should be immediately shown a brief, non-punitive educational message explaining what they missed and what they should look for next time. This just-in-time training at the moment of failure is far more effective than generic training delivered months earlier.

4. Create a Reporting Culture

One of the most important outcomes of phishing training is creating a culture where staff feel comfortable reporting suspicious emails. Every reported email is valuable intelligence — it alerts your IT team to threats that have bypassed technical filters and may be targeting other staff members.

Make reporting easy. Implement a "Report Phishing" button in your email client (available in Microsoft Outlook and Google Workspace) that allows staff to report suspicious emails with a single click. Acknowledge every report promptly, even if the email turns out to be legitimate. Never criticise someone for reporting — even false positives are valuable because they show staff are engaged and vigilant.

Consider recognising and rewarding staff who consistently report suspicious emails. Positive reinforcement is far more effective at driving behaviour change than punishment for failures.

5. Tailor Training to Roles and Risk

Not all employees face the same level of phishing risk. Finance staff who process payments are prime targets for Business Email Compromise. Executive assistants who manage senior leaders' calendars and communications are targeted for the access they provide. IT administrators with privileged system access are targeted because their credentials unlock critical infrastructure. HR teams are targeted with fake CVs and job applications containing malware, particularly during recruitment drives when they expect unsolicited attachments from unknown senders.

Your training programme should include role-specific modules that address the particular threats each group faces. Finance teams need intensive training on payment fraud verification procedures and the specific tactics used in invoice redirection scams. Executives need training on the spear phishing tactics deployed against senior leaders, including impersonation of board members, solicitors, and regulatory bodies. New starters should receive phishing awareness training during their induction, before they are exposed to real threats in their inbox. Tailoring the training to each role makes the content more relevant, more engaging, and more effective at preventing the specific attacks most likely to target each group.

Red Flags Every Employee Should Know

Train your staff to look for these common phishing indicators.

Red Flag	What to Look For	Example
Sender address mismatch	Display name says one thing, email address is different	"Royal Mail" but from noreply@rmdelivery-uk.com
Urgency and pressure	Demands immediate action or threatens consequences	"Your account will be closed in 24 hours"
Suspicious links	Hover over links to check the real destination	Link text says "microsoft.com" but goes to "micr0soft-login.com"
Unexpected attachments	Files you did not request, especially .zip, .exe, or macro-enabled	"Invoice attached" from an unknown sender
Generic greetings	"Dear customer" instead of your name	Your bank knows your name — phishers often do not
Grammar and spelling	Errors, awkward phrasing, inconsistent formatting	"Your acount has been compromized"
Requests for sensitive data	Passwords, bank details, personal information via email	"Please verify your login credentials by replying"

Special Considerations for UK Businesses

UK businesses face phishing campaigns specifically tailored to the British market. Common UK-specific phishing themes include HMRC tax refund scams (particularly around Self Assessment deadlines in January), Royal Mail and DPD delivery notification scams, NHS and COVID-related health scams, TV Licensing renewal scams, Companies House filing reminder scams, and ICO and UK GDPR compliance scams.

Your training should include examples of these UK-specific campaigns. Staff who recognise the patterns used in HMRC phishing emails, for example, are far more likely to spot them when they arrive.

The seasonal nature of UK phishing campaigns is an important factor in training timing. HMRC-themed attacks peak in January during Self Assessment season and again in April around the end of the tax year. Royal Mail scams surge during the Christmas shopping period in November and December. Back-to-school and university phishing campaigns target education sector staff in September. Your simulated phishing programme should mirror these seasonal patterns, sending HMRC-themed simulations in January and delivery-themed simulations in the run-up to Christmas, to test whether staff can resist the most contextually convincing attacks they are likely to encounter.

UK businesses should also be aware of the increasing sophistication of phishing attacks that exploit trusted UK government digital services. Attackers create near-perfect replicas of GOV.UK pages, Companies House filing portals, and NHS login screens. These spoofed sites often use SSL certificates and domain names that closely resemble legitimate government domains, making them difficult to identify without careful inspection. Training should include specific examples of these UK government impersonation attacks and teach staff to navigate directly to government services by typing the URL themselves rather than clicking links in unsolicited emails.

From a regulatory perspective, the ICO considers staff training an important element of the "appropriate organisational measures" required under UK GDPR. If your business suffers a data breach resulting from a phishing attack, and you cannot demonstrate that staff had received adequate training, the ICO may consider this an aggravating factor when determining any enforcement action or fine.

Measuring Training Effectiveness

A phishing awareness programme without measurement is just a cost. You need to track metrics that demonstrate whether the training is actually reducing risk.

The primary metrics to track are: phishing simulation click rate (should decrease over time), credential submission rate on simulated phishing pages (should decrease), phishing report rate (should increase), time to report (should decrease), and the percentage of staff who have completed training modules. Review these metrics quarterly and adjust your programme based on the trends. If click rates are not declining, your training content or frequency needs to change. If report rates are low, your reporting process may be too complicated.

Beyond quantitative metrics, gather qualitative feedback from your staff. Anonymous surveys can reveal whether employees find the training engaging and relevant, whether they feel confident identifying phishing attempts, and whether they understand the reporting process. Staff feedback often highlights practical improvements that metrics alone cannot capture — for instance, that the reporting button is difficult to find on mobile devices, or that the simulated phishing emails are so similar each month that staff recognise them as simulations rather than developing genuine detection skills.

Present your phishing awareness metrics to senior leadership quarterly. Framing the data in business risk terms — showing the reduction in successful phishing click-throughs alongside the potential financial impact of a successful attack — secures ongoing executive support and budget for the programme. Many UK businesses find that their phishing metrics become a valuable component of their wider risk reporting, demonstrating tangible, measurable improvement in their security posture to board members, insurers, and clients who increasingly ask about cyber security preparedness during procurement and due diligence processes.

Getting Started: A Practical Roadmap

If your business does not currently have a phishing awareness programme, here is a practical roadmap to get started.

In month one, conduct a baseline simulated phishing test and choose a training platform. In month two, deliver initial training to all staff and set up the phishing report button. In month three, begin monthly simulated phishing tests with just-in-time training for those who fail. From month four onwards, continue monthly simulations, deliver quarterly refresher training on new threats, and review metrics quarterly to adjust the programme.

Several platforms offer phishing simulation and training services suitable for UK SMEs, including KnowBe4, Proofpoint Security Awareness, Cofense, and Barracuda PhishLine. Your managed IT provider may also offer phishing simulation as part of their security services.

The investment required is modest — typically £15 to £30 per user per year for a full simulation and training platform. When you compare this to the potential cost of a successful phishing attack, the return on investment is overwhelming.
