How to Insure a UK Garage: Public Liability, Contents, and Block Cover Explained

Garage insurance is one of those topics that is simpler than it looks once you know the structure, and more important than it looks because the consequences of getting it wrong are large.

This is what you need, what you do not, and how the insurance picture changes as you scale a portfolio.

The four covers that matter

A standard UK garage insurance policy in 2026 typically bundles four covers:

Buildings cover. Replaces the structure if it is damaged or destroyed by fire, storm, theft, or malicious damage. Standard sum insured: £8,000-15,000 for a typical single garage. This is the foundation of the policy.

Public liability. Pays out if someone is injured on your premises. Standard sum insured: £1-2 million. This is the most important cover on the policy because the consequences of a claim are vastly bigger than the consequences of any other risk. A tenant slipping on a wet concrete floor and breaking a hip can produce a six-figure claim. £2m of public liability cover on a £100/year premium is one of the cheapest pieces of risk transfer in personal finance.

Loss of rent. Pays a portion of rent during periods when the garage is uninhabitable due to insured damage. Standard cover: 12 months. Useful in the worst-case scenarios but rarely claimed in practice.

Theft of contents (your contents). Pays out for things you stored in the garage as the owner. Most garage landlords do not have valuable contents in a let unit, but the cover is usually included.

What you don't insure

The tenant's contents. Your insurance does not cover the things the tenant stores. The licence agreement should make clear that the tenant insures their own contents, and that the landlord accepts no responsibility for them. This is standard.

Tenant's vehicle storage. The tenant car, bike, or motorcycle stored in the garage is the tenant own insurance problem. Confirm that your tenancy agreement says this clearly.

Cosmetic damage. Most policies exclude wear and tear, gradual deterioration, and routine maintenance. Cover starts at the point of an insured event.

The single-policy stack

For a single garage in 2026, expect to pay £80-150 per year for a comprehensive policy with all four covers. Specialist providers (Catlin, Lock-up Insurance, NMU) typically cover garages well; mainstream insurers (Aviva, Direct Line) often do not quote, or quote at unfavourable rates.

Get three quotes when you start. After year one, renewals from the specialist provider are usually competitive enough that re-shopping every year produces little benefit.

When you scale: block cover

Once you have 4+ garages, block cover becomes economically interesting. A single policy covering multiple garages on different sites is typically priced at 60-75% of the per-unit cost of individual policies.

Block cover advantages:

• Lower per-unit cost.
• One renewal date, one set of paperwork.
• Standardised coverage across the portfolio.
• Adding new garages mid-policy is usually possible at pro-rata rates.

Block cover disadvantages:

• A single policy concentrates risk — if there is a dispute or claim, the entire portfolio insurance status can become uncertain.
• Underwriting at portfolio level can be slower than individual.
• Policy renewal becomes a bigger negotiation than a single policy renewal.

For 5-15 garages, block cover usually wins. For 20+ garages, consider splitting into two block policies with different insurers — diversification of insurance counterparty becomes meaningful at scale.

The risks the policy doesn't cover

Three risks that most policies exclude or limit:

Subsidence. Standard residential policies cover subsidence; many garage policies do not, or charge a substantial excess (£1,000-2,500). Check the policy wording.

Flood. Standard policies typically cover flood, but with the caveat that flood-zone properties may attract higher excesses. Check the property flood-zone classification and the policy flood exclusions.

Tenant fraud or non-payment. Insurance does not cover deliberate fraud by the tenant or rent arrears. Loss of rent cover is for insured-event-driven voids, not tenant problems.

The claims you'll actually make

Three claim types account for most garage insurance claims:

Storm damage to the door or roof. Common. Typical settlement: £400-1,500.

Theft and forced entry. Less common but more disruptive. Typical settlement: £200-1,500 plus repair to forced entry damage.

Vandalism. Occasional, mostly malicious damage to doors. Typical settlement: £150-700.

Claims for serious public liability incidents are rare but exist — slips, falls, items falling on tenants. The cost of any single such claim makes the public liability cover invaluable.

The practical setup

For most garage investors, the right insurance structure is:

• A specialist provider for the policy.
• £2m of public liability as a non-negotiable.
• Loss of rent included.
• Contents cover for any stored goods you actually own.
• Block cover from the third or fourth garage onwards.
• Annual review of the policy at renewal — particularly the sums insured, which need to track inflation in rebuild costs.

Insurance is a small line item in the cash flow, but it is the line item that prevents catastrophe. A £2m public liability claim against an uninsured landlord is the kind of event that ends investing careers. A £100/year policy is what prevents it.
