INSURANCE GUIDE Office Insurance - what businesses in office premises need in 2026 |
TL;DR
- Office insurance is a combined policy covering the office contents, IT equipment, business interruption, and public and employers liability for businesses operating from office premises.
- Professional indemnity (PI) is a separate but often essential cover for office-based professional services businesses - it is not included in standard office insurance.
- Cyber insurance is increasingly important for office businesses as standard office policies exclude most cyber-related losses including ransomware, data breach, and business email compromise.
- IT equipment should be insured at replacement cost, not depreciated value - office IT loses book value quickly but replacement cost remains high.
- Business interruption cover for office businesses should include a provision for increased cost of working - the extra cost of operating from temporary premises while the office is unavailable.

What Is Office Insurance?
Office insurance (also called office combined or business premises insurance for offices) is a package of covers for businesses operating from office premises, whether they own the building or lease it. It combines property insurance (contents and IT equipment), business interruption, and liability insurance (public, employers, and premises liability) into a single policy.
Professional services businesses are the typical office insurance customer - law firms, accountancy practices, marketing agencies, IT consultancies, engineering firms, architects, and similar. These businesses tend to have relatively modest physical asset values compared to retail or industrial businesses, but high exposure to professional liability claims, cyber risks, and business interruption if their IT systems or office access is disrupted.

The Cyber Insurance Gap
Standard office insurance excludes cyber-related losses in virtually all policy wordings. This exclusion covers: ransomware attacks and the costs of recovering systems and data; business interruption caused by a cyberattack preventing access to IT systems; data breach costs including notification, regulatory investigation, and legal costs; business email compromise (BEC) and social engineering fraud resulting in fraudulent payment transfers.
For office-based businesses that rely on IT systems for their operations (which is almost all modern office businesses), a standalone cyber insurance policy is essential. Cyber premiums have risen significantly in recent years following a surge in ransomware attacks, but standalone cyber policies remain available for most SME office businesses at premiums of GBP 500 to GBP 3,000 per year depending on revenue and IT security posture.
Professional Indemnity: Why It Is Separate
Professional indemnity (PI) insurance covers claims arising from negligent professional advice, design errors, or service failures. Standard office insurance does not include PI. For professional services firms - solicitors, accountants, architects, engineers, IT consultants, management consultants, financial advisers - PI is often the most important insurance they hold and may be mandatory under their professional regulatory requirements.
PI is always a separate policy because the risk assessment is highly specific to the type of professional work, the client contracts, the fee income, and the firm claim history. Office insurance underwriters do not assess these factors - PI underwriters do.
How Much Does Office Insurance Cost?
Annual indicative costs for 2026:
- Small office, 1-5 staff, contents GBP 50K, PL GBP 1 million + EL: approximately GBP 200 to GBP 500
- Medium office, 5-20 staff, contents GBP 150K, PL GBP 2 million + EL: approximately GBP 500 to GBP 1,200
- Larger office or multiple locations: approximately GBP 1,200 to GBP 3,000

Frequently Asked Questions
Does office insurance cover equipment I take home?
Standard office insurance typically covers contents and equipment at the specified office address. Equipment taken home by staff for hybrid working is often not covered or subject to a sublimit. An all-risks extension or a business equipment floater can extend cover to equipment used away from the office address. Check the policy schedule for any away-from-premises cover limit.
Do I need public liability if only clients visit my office?
Yes. PL covers claims from clients, visitors, delivery personnel, and any other third parties who suffer injury or property damage on or because of your office premises. A client tripping on a damaged carpet, a delivery driver slipping on an ungritted step in winter, or a client laptop being damaged by a coffee spill during a meeting would all potentially give rise to PL claims.
Is business interruption cover worth it for an office?
For most office businesses, yes. If the office becomes inaccessible due to fire, flood, or structural damage, the business loses income and continues to incur fixed costs while it cannot operate normally. BI cover pays the gross profit lost during the period of interruption. The increased cost of working extension also covers the extra cost of operating from temporary premises. For office businesses with high recurring client obligations, BI cover can be critical.
What does office insurance not cover?
Standard office insurance does not cover professional indemnity (negligence in professional services), cyber risks (ransomware, data breach, BEC), motor vehicles, employee fraud, and fidelity risks. Each of these requires a separate policy. Understanding these gaps is as important as understanding what the office policy covers.
Does office insurance cover a home office?
Standard commercial office insurance does not cover a home office. Most standard home insurance policies also exclude business contents and equipment beyond a low limit (typically GBP 1,000 to GBP 2,500). A separate home business insurance policy or a business contents extension to a home insurance policy can provide appropriate cover for home-based business activities.
