Rent Guarantee Insurance vs Void Period Savings Buffer UK 2026
Rent guarantee insurance pays a landlord's rent (typically up to 6–12 months, often with legal expenses cover for eviction) if a tenant stops paying, for an annual premium usually calculated as a percentage of monthly rent. Self-insuring by building your own savings buffer avoids the premium and any claim exclusions, but leaves you fully exposed if a tenant default coincides with limited savings or occurs early in your portfolio.
At a Glance
| Feature | Rent Guarantee Insurance | Void Period Savings Buffer |
|---|---|---|
| Typical annual cost | Roughly 3%–6% of annual rent, varies by tenant referencing quality | None — opportunity cost of holding cash instead of investing it |
| Payout if tenant stops paying | Rent paid up to policy limit (often 6–12 months), sometimes including legal costs to evict | Draw down your own savings — no external limit, but no external top-up either |
| Claim conditions | Requires proper referencing at the start of the tenancy; excludes some pre-existing arrears scenarios | No conditions — it is your own money |
| Best suited to | Landlords with one or few properties who cannot absorb a long void/arrears period | Landlords with multiple properties or strong cash reserves who can self-insure across a portfolio |
| Ongoing cost if never claimed | Premium paid every year regardless of claims | Buffer sits earning interest/investment return if unused |
| Administrative burden | Insurer handles legal process and rent payment during a claim | Landlord manages the entire process and cash flow themselves |
When Rent Guarantee Insurance Wins
- You own one or few rental properties and cannot easily absorb months of lost rent
- You want legal expenses cover bundled in to help fund possession proceedings if needed
- Your mortgage or personal finances are tightly dependent on rental income continuing uninterrupted
When Void Period Savings Buffer Wins
- You have a larger portfolio where losses on one property can be absorbed by others
- You have strong cash reserves and prefer to avoid recurring insurance premiums
- You reference tenants very thoroughly and have a low historical arrears rate
Frequently Asked Questions
How much does rent guarantee insurance typically cost?
Premiums usually range from around 3% to 6% of the annual rent, varying by the insurer, the level of legal expenses cover included, and how thoroughly the tenant was referenced, with poorly-referenced tenants sometimes excluded from cover altogether or attracting a higher premium.
Does rent guarantee insurance cover legal costs to evict a non-paying tenant?
Many policies bundle in legal expenses cover to help fund possession proceedings (obtaining a court order to regain the property) alongside the rent payments themselves, though the specific level of legal costs covered and any policy excess varies significantly between providers, so check the policy wording carefully.
Is rent guarantee insurance worth it for a portfolio landlord?
For landlords with several properties, the risk of one tenant defaulting can often be absorbed by rental income from other properties, making self-insurance (holding a cash buffer) a viable and potentially cheaper alternative over time compared to paying a premium on every single property in the portfolio.

What conditions must be met to claim on rent guarantee insurance?
Most policies require the tenant to have passed a proper referencing check (credit check, employment/income verification, previous landlord reference) before the tenancy started, and some exclude claims for arrears that began before the policy was taken out, so read the policy wording carefully before assuming cover applies.
How large a savings buffer should a landlord hold instead of insurance?
A common rule of thumb is holding 3–6 months of mortgage payments and running costs per property as a minimum buffer, though landlords with multiple properties may hold a proportionally smaller buffer per property since the risk of simultaneous defaults across a diversified portfolio is lower.
