What Is Cyber Essentials?

A Simple, Effective Way to Protect Your London Business

Cyber Essentials is a UK government-backed certification scheme that helps organisations in London and across the UK protect themselves against common online attacks.

The scheme is built around five foundational technical controls, set by the National Cyber Security Centre and managed through IASME. Together, they give customers, suppliers, insurers, and procurement teams a clear signal that basic cyber hygiene is in place.

Why Cyber Essentials

The Case for Cyber Essentials Gets Stronger all the Time

What began as a government procurement requirement has become a commercial baseline - and for many London businesses, the question is no longer whether to certify but how quickly.

Cyber Essentials started as a government procurement requirement. It's now a baseline commercial signal - in supply chains, insurance applications, and client due diligence across every major sector represented in London's business community.

Government Contracts Require It

Any organisation tendering for UK central government contracts must hold a valid Cyber Essentials certificate issued within the last twelve months. That requirement has been in place since the scheme launched in 2014 and applies without exception - including to the significant volume of government contract work originating from London-based departments and agencies.

Supply Chains Demand It

London's concentration of financial institutions, law firms, and technology companies means supply chain certification pressure is among the highest of any UK city. Major banks, insurers, and asset managers routinely require technology, legal, and advisory suppliers to hold a valid certificate before a contract is awarded - and that requirement is spreading steadily through every tier of their supply chains.

It Blocks Most Attacks

The NCSC consistently reports that the five controls covered by Cyber Essentials would prevent the majority of common cyberattacks targeting UK businesses. For London organisations - operating at higher target density than almost anywhere else in the UK - that protection is not theoretical. It addresses the opportunistic, volume-based threats that account for most successful breaches.

It Reduces Insurance Costs

Many cyber insurers offer reduced premiums to certified organisations. Eligible SMEs also receive free cyber liability insurance via IASME on achieving Cyber Essentials - covering data loss, cyber extortion, and business interruption up to £25,000. In a city where professional indemnity and cyber risk insurance costs are already significant, certification offers a tangible financial return alongside the security benefit.

Why London Businesses Need Cyber Essentials

Certification Pressure Is Higher in London Than Almost Anywhere

For London businesses, Cyber Essentials has moved well beyond a government procurement checkbox.

London's business environment creates a distinctive set of drivers for Cyber Essentials certification - stronger supply chain pressure, greater government contract exposure, and a higher concentration of regulated industries than any other UK city.
