Common Office Building Claims (Real Examples & Costs)

Introduction

Office buildings feel “low risk” compared to sites like factories, pubs, or construction projects—but claims still happen all the time. In fact, offices combine three things insurers pay close attention to: people (staff and visitors), property (buildings, contents, IT), and business interruption (loss of income or extra costs after an incident).

This guide breaks down the most common office building claims we see across UK workplaces, using realistic examples and cost ranges to help you understand what can go wrong, what it can cost, and how to reduce the likelihood of a claim.

Important note: Costs vary by location, building type, insurer, excess, and how quickly issues are reported. The examples below are representative scenarios, not guarantees.

1) Escape of water (leaks from pipes, toilets, and HVAC)

Why it’s common: Offices often have multiple toilets, kitchenettes, water coolers, and sometimes air conditioning/heat pump condensate lines. Small leaks can run for hours (or days) before anyone notices—especially overnight or over a weekend.

Real example scenario

A second-floor toilet cistern valve sticks open on Friday evening. Water overflows, seeps through the floor, damages ceiling tiles and lighting on the floor below, and saturates carpet tiles and skirting.

Typical costs

• Emergency call-out and leak trace: £250–£1,200

• Drying and dehumidifiers (1–3 weeks): £800–£4,000

• Ceiling tiles, electrics, redecorations: £2,000–£12,000

• Flooring replacement (carpet tiles): £1,500–£10,000

• Total claim range: £4,500–£30,000+

Risk reduction tips

• Fit leak detection and automatic shut-off valves in riser cupboards and plant rooms.

• Schedule out-of-hours checks for multi-tenant buildings.

• Keep a simple water isolation map and label stopcocks.

2) Storm damage (roofing, gutters, and water ingress)

Why it’s common: Flat roofs, ageing membranes, blocked gutters, and high winds can combine to cause water ingress. Even “minor” roof issues can lead to major internal damage.

Real example scenario

After a winter storm, high winds lift flashing around a roof penetration. Rainwater enters, runs along cable trays, and drips into a meeting room. The leak is missed for a week because the room isn’t used daily.

Typical costs

• Temporary roof repairs: £500–£2,500

• Permanent roof repair and flashing: £1,500–£10,000

• Internal repairs (plaster, paint, ceiling): £1,000–£8,000

• Replacement of damaged equipment/furniture: £500–£15,000

• Total claim range: £3,000–£35,000+

Risk reduction tips

• Arrange annual roof inspections (and after major storms).

• Clean gutters and check downpipes at least twice per year.

• Keep photographic records of roof condition and maintenance.

3) Accidental damage to glazing (windows, internal partitions, doors)

Why it’s common: Modern offices often use lots of glass—external glazing, internal partitions, and glass doors. Accidental impact claims are frequent.

Real example scenario

A delivery trolley clips a glass entrance panel. The glass cracks, and the area must be made safe immediately.

Typical costs

• Emergency make-safe and boarding: £250–£900

• Replacement glazing (standard): £600–£2,500

• Replacement glazing (specialist/large panels): £2,500–£12,000

• Total claim range: £850–£13,000

Risk reduction tips

• Use manifestation markings on glass doors/partitions.

• Add bollards or barriers near vulnerable entrance glazing.

• Review whether your policy includes accidental damage and glass cover.

4) Theft and attempted theft (including out-of-hours break-ins)

Why it’s common: Laptops, phones, and small IT equipment are high value and easy to remove. Offices can also be targeted for copper theft or tools stored by maintenance teams.

Real example scenario

A small office is broken into overnight. A rear window is forced. Laptops and monitors are stolen, and the intruder causes additional damage to doors and frames.

Typical costs

• Stolen IT equipment (10 laptops + peripherals): £6,000–£18,000

• Repairs to doors/windows/locks: £500–£4,000

• Data recovery / incident response (if needed): £1,000–£15,000

• Total claim range: £7,500–£35,000+

Risk reduction tips

• Ensure alarms are maintained and set correctly.

• Use access control and lockable storage for laptops.

• Consider cyber cover if sensitive client data could be exposed.

5) Fire (electrical faults, kitchen fires, and arson)

Why it’s common: Offices have lots of electrical equipment, chargers, and sometimes small kitchens. Fire claims can be rare but severe.

Real example scenario

A faulty power strip overheats under a desk. A small fire starts after hours. The sprinkler system activates, limiting fire spread—but water damages multiple rooms.

Typical costs

• Fire damage repairs (localised): £5,000–£40,000

• Smoke damage cleaning and redecorations: £3,000–£25,000

• Sprinkler/water damage restoration: £5,000–£60,000

• Business interruption (temporary relocation, extra costs): £2,000–£100,000+

• Total claim range: £15,000–£250,000+

Risk reduction tips

• PAT testing and fixed wiring inspections on schedule.

• Clear rules for kitchen appliances and lithium battery charging.

• Keep fire doors operational and avoid wedging them open.

6) Slip, trip, and fall (public and employers’ liability)

Why it’s common: Wet floors, loose carpets, trailing cables, uneven paving, and poor lighting are classic causes. These claims can involve staff, clients, or contractors.

Real example scenario

A visitor slips on rainwater in the reception area on a busy morning. They suffer a wrist fracture and claim for injury and lost earnings.

Typical costs

• Minor injury claims: £1,000–£5,000

• Fracture/longer recovery: £5,000–£25,000

• Legal costs and investigation: £1,000–£15,000

• Total claim range: £6,000–£40,000

Risk reduction tips

• Use wet floor signage and entrance matting.

• Implement a simple housekeeping checklist.

• Record incidents promptly with photos and witness statements.

7) Employers’ liability claims (manual handling, stress, and workplace injury)

Why it’s common: Offices still have lifting (paper, IT equipment, furniture), repetitive strain, and occasionally allegations of stress-related illness.

Real example scenario

An employee injures their back moving archive boxes without a trolley. They’re off work for several weeks and allege inadequate training.

Typical costs

• Minor musculoskeletal injury: £2,000–£8,000

• Longer absence and physio: £8,000–£25,000

• Legal/claims handling costs: £1,000–£10,000

• Total claim range: £4,000–£35,000

Risk reduction tips

• Provide manual handling training and basic equipment (trolleys).

• Encourage early reporting and occupational health support.

• Keep training records and risk assessments up to date.

8) Accidental damage to fixtures and fittings (impact, spills, and contractor error)

Why it’s common: Offices are constantly being moved around—desks, screens, meeting rooms, fit-outs. Contractors can cause damage during routine works.

Real example scenario

A contractor drilling into a wall hits a concealed pipe or cable, causing a leak and power outage.

Typical costs

• Emergency response and make-safe: £300–£2,000

• Repairs to pipe/cable and reinstatement: £1,500–£12,000

• Additional costs from downtime: £500–£20,000

• Total claim range: £2,500–£35,000

Risk reduction tips

• Use permit-to-work and require RAMS (risk assessments and method statements).

• Keep up-to-date as-built drawings and service maps.

• Supervise high-risk works and isolate services where possible.

9) Electrical surge and equipment damage (IT, servers, comms)

Why it’s common: Power fluctuations, lightning, faulty UPS units, and ageing distribution boards can damage IT equipment. Even a short outage can create big disruption.

Real example scenario

A power surge damages network switches and a small on-site server. The office loses phone and internet for two days.

Typical costs

• Replacement hardware: £1,000–£20,000

• IT support and reconfiguration: £500–£8,000

• Business interruption / extra expense: £1,000–£30,000

• Total claim range: £2,500–£55,000

Risk reduction tips

• Use surge protection and appropriately sized UPS.

• Review backup strategy (cloud, off-site, tested restores).

• Consider whether you need equipment breakdown cover.

10) Business interruption (BI) following insured damage

Why it’s common: BI often follows another incident—fire, flood, escape of water, storm damage. The property repair might be manageable, but the downtime can be the real cost.

Real example scenario

A water leak forces a 25-person office to work from home for two weeks while drying and repairs take place. The company incurs extra costs for temporary equipment and loses billable time.

Typical costs

• Temporary office space / hot desks: £500–£5,000

• Extra IT equipment and setup: £1,000–£10,000

• Loss of gross profit (varies widely): £5,000–£250,000+

• Total BI impact: £6,500–£265,000+

Risk reduction tips

• Ensure BI indemnity period matches reality (often 12–24 months).

• Document a simple business continuity plan.

• Check policy wording for “denial of access” and “non-damage BI” options.

What insurance typically responds to office building claims?

Depending on your setup (owner-occupied, tenant, serviced office, multi-let), claims may fall under:

• Commercial buildings insurance (structure, landlord fixtures)

• Office contents insurance (furniture, computers, stock, tenant improvements)

• Commercial combined insurance (bundled property + liability + BI)

• Employers’ liability (legal requirement if you employ staff)

• Public liability (injury/property damage to third parties)

• Business interruption (loss of gross profit/extra expense)

• Equipment breakdown (mechanical/electrical failure, optional)

• Cyber insurance (data breach, cyber extortion, incident response)

A common issue is the “grey area” between landlord and tenant responsibilities. For example, who insures the glass? Who covers tenant fit-out? Who pays for trace and access? Getting this clear before a claim is half the battle.

Quick checklist: how to reduce office building claims

• Keep a written maintenance schedule (roof, gutters, electrics, HVAC).

• Install leak detection in high-risk areas.

• Improve entrance matting and housekeeping controls.

• Tighten physical security (locks, alarms, access control).

• Review sums insured and BI indemnity period annually.

• Keep incident logs, photos, and contractor paperwork.

FAQs

What is the most common office building insurance claim?

Escape of water is one of the most frequent causes of property damage claims in offices, especially from toilets, kitchenettes, and hidden pipework.

How much does an escape of water claim cost in an office?

Many office escape of water claims fall between £4,500 and £30,000, depending on how quickly the leak is found and how much reinstatement is needed.

Do office claims increase premiums?

They can. Insurers look at frequency and severity. Multiple small claims (even under £5,000) can impact renewal terms, excesses, and insurer appetite.

Does buildings insurance cover a tenant’s contents?

Usually not. Buildings insurance typically covers the structure and landlord fixtures. Tenants often need their own contents and tenant improvements cover.

Is business interruption included automatically?

Not always. BI is often an optional add-on or included within commercial combined policies. The indemnity period and basis of settlement matter.

Conclusion

Office buildings may look straightforward, but the claims landscape is surprisingly varied—from escape of water and storm damage to liability claims and business interruption. The good news is that many of the most expensive losses are preventable with basic maintenance, clear responsibilities between landlord and tenant, and a policy that matches how the building is actually used.
