There's no single answer to "what landlord insurance do I need?" — because landlord insurance isn't one product. It's a bundle of covers, and how you put that bundle together determines whether you're properly protected or sitting on a gap that will cost you dearly when something goes wrong.
This guide breaks down each component, tells you what actually matters, and flags the mistakes we see most often when landlords come to us after a problem.
1. Buildings Insurance — and Why Reinstatement Value Matters
Buildings insurance is the foundation. It covers the cost of repairing or rebuilding your property if it's damaged by fire, flood, subsidence, escape of water, or malicious damage by tenants.
The most common and expensive mistake landlords make here is insuring for the wrong figure.
Buildings insurance must be based on the reinstatement value — the cost to rebuild the property from scratch — not the market value. In many parts of the UK, especially London and the South East, these figures are very different. A property worth £600,000 on the market might cost £320,000 to rebuild. If you insure for £600,000 you're not over-protected — you may still be underinsured if rebuild costs have risen since your policy was set.
Get a rebuild cost assessment from a RICS surveyor every few years, or at least use the BCIS rebuild cost calculator as a guide. Then make sure your insurer applies index-linking so the sum insured keeps pace with construction cost inflation.
A portfolio landlord's kitchen fire caused total kitchen destruction and severe smoke damage throughout the property. Because the building was insured on the correct reinstatement value — not market value — the claim settled in full. Many landlords we speak to would have been underinsured by 20–30% in the same situation.
2. Loss of Rent / Alternative Accommodation
If your property becomes uninhabitable following an insured event, you lose rental income while it's being repaired. Loss of rent cover reimburses you for that income — typically for up to two years, sometimes longer.
Make sure your policy includes an adequate indemnity period. Reinstatement after major damage — especially involving fire or flood — routinely takes 12–18 months. An indemnity period of six months won't be enough.
Some policies also cover the tenant's alternative accommodation costs if the lease obliges you to provide it. Check your tenancy agreements and make sure your policy aligns.
3. Property Owners' Liability
As a landlord, you have a duty of care to your tenants and visitors. If someone is injured on your property — a tenant trips on a loose step, a visitor slips on an icy path — and holds you responsible, property owners' liability covers your legal defence costs and any damages awarded against you.
Standard policies include £2 million of liability cover. For a portfolio of properties, or any property with higher public footfall, consider £5 million or more. The cost difference is minimal; the protection difference is significant.
4. Contents Cover — Whose Responsibility Is What?
Unfurnished lettings: your contents exposure as a landlord is limited to fixtures and fittings — white goods you supply, fitted carpets, curtains. Your tenants are responsible for their own belongings.
Furnished lettings: you need contents cover for everything you've provided. Keep an inventory with photographs and approximate replacement values. Insurers will not settle a contents claim without evidence of what was there.
Standard home insurance does not cover a property being let to tenants. If your buy-to-let property is insured on a residential home policy, you likely have no valid cover at all. This is one of the most serious gaps we encounter.
5. Legal Expenses — Underrated and Underused
Legal expenses cover is often an add-on that landlords skip to save £30–50 a year on premium. Then they face an eviction dispute, a disrepair claim, or a rent recovery action and find themselves paying solicitor fees out of pocket.
Good legal expenses policies cover:
- Eviction proceedings and Section 21 / Section 8 notices
- Rent recovery from defaulting tenants
- Defence of disrepair or injury claims brought by tenants
- Employment disputes if you have staff (e.g. a caretaker)
- Property damage disputes with contractors
Add it. The cost is trivial compared to even one contested eviction.
6. Rent Guarantee Insurance
This is different to loss of rent. Rent guarantee insurance covers you when a tenant simply stops paying — no damage to the property, no insured event. The policy pays your rent while you go through the eviction process.
It's particularly valuable in the current environment, where Section 21 reform means evictions take longer. Most policies pay out for 6–12 months of missed rent and cover legal costs up to £100,000.
The key requirement: your tenants must have passed a credit and reference check before the policy is taken out. You can't insure a known bad risk.
7. Portfolio Policies — If You Own Multiple Properties
If you own more than two or three investment properties, a single portfolio policy almost always makes more sense than individual policies per property. You get:
- One renewal date
- Simplified claims — one insurer, one process
- Potential premium savings through volume
- Easier to add or remove properties as your portfolio changes
The key thing to check: does the policy automatically cover new acquisitions between renewals? Most good portfolio policies do — usually for 30 or 60 days — but you still need to notify the insurer promptly.
8. What to Check at Every Renewal
Landlord insurance is not a set-and-forget purchase. At every renewal, ask yourself:
- Has the rebuild cost of my properties changed?
- Have I done any improvements that increase the rebuild value?
- Has the rental income changed — is my loss of rent cover still adequate?
- Am I still on the right type of tenancy (AST, HMO, commercial, holiday let)?
- Have I added any properties to the portfolio?
- Have I changed any of the terms of my tenancy agreements?
Any of these can affect whether your current policy is still fit for purpose. A broker who simply rolls your policy over without asking these questions is not doing their job properly.
Most landlord insurance problems we encounter aren't about the premium — they're about policies that were set up years ago and never properly reviewed. A 30-minute conversation at renewal is enough to catch the gaps before they matter.
