Landlord Insurance

What Factors Affect The Cost Of Landlord Insurance?

Fact Checked

Landlord insurance premiums are determined by the rebuilding cost of your property, its location, the type of tenants you let to, your claims history, the level of cover you choose, and the age and condition of the building.

Premiums vary widely between properties. A one-bedroom buy-to-let flat in a low-crime area with a professional tenant will cost far less to insure than an HMO in a flood-prone postcode with a history of claims.

Some of these factors are within your control, and knowing which ones gives you an edge when comparing landlord insurance quotes. Unlike standard home insurance, landlord cover prices commercial letting risks, so the factors that drive your premium are different.

This guide breaks down each factor, explains how insurers use it to set your premium, and shows you where you can take action to reduce costs.

Key Takeaway

Rebuild cost, not market value, is what your buildings premium is based on, so getting that figure right matters more than anything else on the form. Tenant type and claims history are the next biggest levers, and the gap between a single professional tenant and an HMO can be 50% or more. Remember the premium is tax-deductible against your rental income.

Compare landlord insurance quotes and check you are not paying for cover you do not need.

How does property value affect the premium?

Landlord buildings insurance is based on the rebuilding cost of your property, not its market value, so a higher rebuilding cost means a higher premium because the insurer faces a greater potential payout.

Rebuilding cost vs market value

The rebuilding cost is what it would cost to reconstruct the property from scratch, including materials, labour, and professional fees. This can differ sharply from the market value.

A period property in an expensive postcode might have a market value of £500,000 but a rebuilding cost of £250,000. A property with unusual construction methods may cost more to rebuild than its sale price.

Getting the rebuilding cost right

Underinsuring means claims may be reduced proportionally, which insurers call applying the average. The RICS Building Cost Information Service provides estimates, or you can commission a surveyor’s valuation for a precise figure.


How does location affect the price?

Your postcode is one of the first things insurers assess, as it determines your exposure to crime, flooding, subsidence, and storm damage.

Flood and subsidence risk

Properties in flood-risk areas or on shrinkable clay soils face higher premiums. Subsidence claims are among the most expensive, and some insurers decline cover entirely for properties with a subsidence history.

Crime rates

Higher local crime rates increase the risk of theft, vandalism, and malicious damage. Installing alarm systems, reinforced locks, and CCTV can partially offset the premium impact.

Comparing investment locations

Even neighbouring postcodes can produce different quotes. If you are comparing properties to invest in, factoring in insurance cost for each location gives a more accurate picture of your total running costs.


How does tenant type affect insurance costs?

Insurers view tenant type as a key risk factor, and the difference between the cheapest and most expensive categories can be 50% or more.

Tenant type Risk level Premium impact
Single professional Lowest Baseline premium
Family Low to moderate Slight increase over professional
Sharers or students Moderate to high 20% to 50% higher than professional
HMO (multiple tenants) Highest 50% to 100%+ higher, due to shared facilities, fire safety, and licensing
Housing benefit tenants Varies Some insurers charge more, though the risk profile depends on the individual tenant

HMOs and licensing

HMO insurance costs more because of the number of occupants, shared facilities, and the additional fire safety and licensing obligations. If your property qualifies as a licensable HMO, your insurer will need to see proof of compliance.

Housing benefit tenants

Since May 2026, landlords cannot discriminate against tenants on benefits under the Renters’ Rights Act, though some insurers still factor benefit status into pricing. See gov.uk for the latest landlord obligations.


How does claims history affect your premium?

A clean claims history keeps premiums low, while previous claims signal higher risk and result in higher quotes for three to five years.

Types of claims

Escape of water is the most common landlord claim, accounting for around 29% of all claims. Subsidence claims have a longer-lasting impact on premiums and can make a property difficult to insure altogether.

When not to claim

Avoid making small claims that barely exceed the excess. The premium increase over the following years may cost more than absorbing the repair yourself.


How does your coverage level affect the cost?

More cover costs more, but the gap between basic and full protection is often smaller than landlords expect. Check the insurance product information document for each quote to see exactly what is included.

Cover type What it protects Typical add-on cost
Buildings only Structure, roof, walls, fixtures Included in base premium
Contents Carpets, curtains, white goods, furniture you provide £30 to £60 per year
Rent guarantee Lost rent if tenant defaults or property is uninhabitable £50 to £120 per year
Legal expenses Eviction costs, disputes, tax investigations £20 to £50 per year
Accidental damage Tenant or visitor damage beyond wear and tear £40 to £80 per year

If you provide furniture, carpets, or appliances, adding contents cover is worth the relatively small extra cost. Without it, you would need to replace damaged items out of pocket.

Excess and its effect

A higher voluntary excess reduces your premium, but means you pay more out of pocket on each claim. For most landlords, a £250 to £500 excess strikes the best balance.

Unoccupied property cover

Most policies reduce or exclude cover after 30 consecutive days of the property being empty. If you have void periods between tenancies, consider unoccupied property insurance as an add-on or standalone policy.


How do property age and condition affect the price?

Older properties and those in poor condition cost more to insure because they carry higher risks of structural failure, electrical faults, plumbing leaks, and fire.

Improvements that lower premiums

Recently rewired properties may attract a 5% to 10% saving compared to properties with older wiring. New roofs, updated plumbing, and a modern boiler all reduce risk and can lower your premium.

Properties with a valid EICR and current gas safety record demonstrate good maintenance. Always disclose recent improvements when getting quotes, as insurers do not automatically know about upgrades.

Non-disclosure risk

Failing to disclose known defects can invalidate your policy. Be upfront about the property’s condition, as honesty at the quote stage protects you at the claim stage.

Tax deductibility

Landlord insurance premiums are fully tax-deductible against your rental income, including the Insurance Premium Tax at 12%. Keep your policy documents and premium receipts for your tax return.

Frequently Asked Questions (FAQs)

What is the average cost of landlord insurance?

Annual premiums typically range from £150 to £800 for a standard rental property. HMOs, higher-value properties, and those in high-risk areas may exceed £1,000.

Can I reduce my landlord insurance premium?

Yes. Maintain the property well, keep a clean claims history, increase your voluntary excess, install security measures, and compare quotes annually.

Is landlord insurance a legal requirement?

No, but your buy-to-let mortgage lender will almost certainly require buildings insurance as a condition of the loan. Even without a mortgage, the financial risk of an uninsured rental property is considerable.

Does my property being empty increase the premium?

Most policies reduce or exclude cover after 30 consecutive days of the property being unoccupied. Notify your insurer if your property will be empty between tenancies.

Do claims increase my premium permanently?

No. Claims typically affect your premium for three to five years, after which it should gradually return to standard rates if you have no further claims.

Does tenant type really affect the premium that much?

Yes, the difference between a single professional tenant and an HMO can be 50% to 100% or more. Insurers price based on the number of occupants, shared facilities, and the associated claims risk.
