Cyber Insurance Cost: UK Premium Benchmarks & Underwriting Pricing Drivers
The cost of Cyber Insurance in the UK depends on the size of the business, industry sector, security controls, turnover, data exposure, indemnity limits, claims history, and reliance on third-party technology providers.

Indicative Cyber Costs For Business
Cyber Insurance premiums vary significantly depending on the risk profile of the business and the level of protection required. The figures above should be treated as indicative benchmarks rather than fixed pricing, as every quotation depends on underwriting information and insurer appetite.
Micro & SME Sector

For micro-enterprises, local businesses, and smaller professional service firms, Cyber Insurance can often be arranged at relatively modest premium levels where turnover, data exposure, and system dependency are limited.
Premiums for lower-risk SMEs often start from a few hundred pounds per year, particularly where the business has strong email security, multi-factor authentication, backups, and limited sensitive data exposure.
However, prices can increase quickly where the business handles client funds, sensitive financial data, health information, or high volumes of personal data.
Technology, FinTech, SaaS, and MSPs
Technology, SaaS, fintech, and managed service providers will face a higher minimum premium because their business model is directly dependent on uptime, data integrity, and platform security.
Most UK insurers will combine Cyber Insurance and Professional Indemnity for tech companies because the proximate cause of a loss can be difficult to separate. For example, if a software platform fails after a security incident, the claim may involve both a contractual breach and a cyber breach. Was the loss caused by a failure to deliver the contracted technology service, or by a malicious security event? In many cases, the answer could be both.
In our view, combining Cyber and Tech PI is the right approach because it reduces ambiguity at claim stage. A blended policy helps avoid disputes over which section should respond and gives technology businesses clearer protection where cyber risk and professional liability overlap.
Large and Mid-Market Businesses
Mid-market and enterprise businesses may require more sophisticated Cyber Insurance structures. Premiums are typically driven by the scale of business interruption exposure and the potential aggregation of risk across systems, vendors, and customer data.
Insurer platforms have grown in terms of the size of the business that doesn’t require a manual underwriting submission. If your turnover is excess of £100 million, we will typically require a more detailed underwriting and cyber security questionnaire to be completed.
Cyber excess layers may be used to build a program tower that is sufficient to meet your risk profile and requirements. Access to specialist facilities can allow for +£100m towers to be arranged for large corporate risks.
Main Rating Factors that Cyber Insurance Premiums Are Based
Underwriters assess a series of measurable risk factors to determine how likely a business is to suffer an incident and how severe the financial consequences could be.
Annual Turnover & Record Volume
Annual turnover is one of the first indicators insurers use to estimate cyber exposure. Record volume and percentage of sensitive information would then be equally as important.
A business holding large quantities of Personally Identifiable Information (PII), will usually attract greater underwriting scrutiny. Insurers will want to understand who has access, whether data is encrypted, and how long records are retained.
The greater the volume and sensitivity of data, the greater the potential notification costs, regulatory exposure, legal liability, and reputational harm following a breach.
Industry Sector & US Jurisdiction
Cyber premiums vary significantly by sector. Industries such as healthcare, financial services, legal services, e-commerce, technology, and professional services often attract higher pricing because they may hold sensitive data, hold client money, or may have greater reliance on continuous uptime.
Whereas, US cyber and privacy claims will typically involve higher defence costs and a higher severity of damages awarded for breaches and compensation claims. Insurers may therefore specifically want to understand your exposure to USA PII.
Cyber Hygiene & Claims History
Strong cyber hygiene can have a direct impact on the cost and availability of Cyber Insurance. Insurers will typically assess the strength of your controls such as multi-factor authentication, backups, patch management, encryption, privileged access controls, passwords, and staff training before offering terms.
Businesses with weak controls may face higher premiums, larger excesses, reduced limits, ransomware restrictions, or even insurer declinatures. By improving cyber hygiene before renewal, businesses can present a stronger risk profile, access broader cover, and reduce the likelihood of a costly cyber incident.
If you have been the subject to a cyber threat that would have been insured, even if you didn’t have a policy in force you need to disclose that information.
Unfortunately, you will incur higher premium costs if you have been the subject of cyber insurance claims in the past five years. Insurers will want to understand exactly what occurred, how much the cyber incident cost, and what remedial actions were taken to stop a similar cyber incident occurring again.
Premium Discounts Available For Quality Cyber Security Controls
Cyber Insurance pricing can be heavily influenced by the quality of your security controls. Businesses that can demonstrate strong cyber hygiene are often more attractive to insurers and may achieve better premiums, broader cover, and lower excesses.

Endpoint Detection & Response (EDR)
Insurers increasingly expect businesses to demonstrate active monitoring and protection of endpoints such as laptops, servers, and mobile devices. Strong controls may include endpoint detection and response, vulnerability scanning, patch management, anti-malware protection, privileged access controls, and device encryption
The objective is to show insurers that the business can detect and contain threats before they escalate into major incidents.
Immutable Backups
Standard backups are no longer enough. Insurers prefer immutable backups are backup files that, once written, cannot be changed, deleted, or overwritten. This ensures an unaltered copy is always available, which is essential for fast recovery in the event of ransomware, accidental deletions, or system failures.
