Landlord Unoccupied Property Insurance During Renovation: 2026/27 Guide
Why standard landlord insurance often stops covering an empty rental property during renovation, and what unoccupied property insurance costs and covers in 2026/27.
The gap most landlords don't spot until it's too late
A landlord planning a renovation between tenancies often assumes their existing landlord insurance policy simply continues while the property sits empty and the builders are in. In reality, most standard landlord insurance policies are built around the assumption of a tenant living there, and they impose strict limits β commonly 30 or 60 days β on how long a property can be unoccupied before cover is automatically reduced or voided entirely.

An occupied property has someone present daily who will notice a leak before it causes serious damage, deter opportunistic theft, and generally keep the building in a lived-in, monitored state. An empty property undergoing renovation strips all of that away β added to which, building sites themselves carry inherent risks: exposed structural openings, materials and tools left on site (an attractive target for theft), and a higher chance of accidental damage from the work itself. Insurers price and restrict cover accordingly.
What specialist unoccupied property insurance typically includes
- Buildings cover for fire, storm, flood, and escape of water β usually retained, though sometimes with a higher excess for water damage specifically
- Malicious damage and vandalism cover, often included as standard given the higher exposure of empty properties
- Theft of fixtures, fittings, and sometimes building materials, though this is frequently subject to conditions around site security
- Public liability, in case a contractor, trespasser, or visitor is injured on site
What's often excluded or requires a specific add-on: damage caused directly by the building work itself (better covered by contractor's all-risks or the builder's own public liability insurance), and cover typically lapses if the property remains empty and unrenovated for an extended period after works finish, without further notification.
Worked example: a landlord renovating between tenancies
Situation: A landlord's rental property becomes vacant, and they plan an eight-week renovation (new kitchen, rewire, redecoration) before re-letting.
Standard landlord policy: Cover reduces after 30 days of vacancy under the existing policy's terms β meaning from week five onward, the landlord has little to no effective cover unless action is taken.
Action taken: The landlord notifies their existing insurer of the planned works and vacancy period; the insurer either extends cover under an unoccupied property endorsement (often at a higher premium, e.g. an extra Β£15-Β£25/month) or the landlord takes out a standalone unoccupied property policy for the renovation period, costing roughly 25%-40% more than the annual landlord policy pro-rated for eight weeks.
Conditions imposed: Weekly documented inspections, mains water isolated except when contractors are actively working, and all external doors/windows secured each evening.

- Contact your insurer before the property becomes empty β don't wait until after a claim to find out cover has lapsed.
- Declare the nature and scale of the works β a cosmetic redecoration is treated very differently from a structural extension or full rewire.
- Check your mortgage terms β many buy-to-let mortgages require notification of extended vacancy or significant works.
- Arrange documented, regular inspections β and keep records, since insurers may ask for evidence when assessing a claim.
- Consider contractor's all-risks insurance for the works themselves, separate from the unoccupied property policy covering the building.
The bottom line
The cost of unoccupied property insurance during a renovation is a genuine, sometimes overlooked, project expense β but it's minor compared to the risk of an uninsured escape-of-water or vandalism claim on an empty property mid-renovation. Building the extra premium into your renovation budget, and notifying your insurer and lender before the property sits empty, closes a gap that catches out more landlords than most expect.
Frequently asked questions
Does standard landlord insurance cover an empty property during renovation?
Usually only for a limited period β most standard landlord policies restrict or exclude cover once a property has been unoccupied for 30 or 60 consecutive days, and many exclude cover for damage caused during building or renovation work entirely, even within that window.
Why do insurers treat empty properties as higher risk?
Empty properties are more vulnerable to undetected water leaks, vandalism, squatting, and theft (particularly of building materials and fittings on a renovation site), because no one is present daily to spot and respond to problems early.
What does specialist unoccupied property insurance typically cover?
It usually covers buildings insurance (fire, storm, flood, escape of water) and often malicious damage or vandalism, sometimes theft of fixtures and building materials, tailored specifically for periods when no one is living at the property, including during renovation works.
How much does unoccupied property insurance cost compared to standard landlord insurance?
It's typically more expensive β often 20%-50% more than an equivalent standard landlord policy β reflecting the higher risk insurers associate with an empty, unmonitored property, particularly one undergoing building work.
Do I need a separate policy for renovation work specifically?
Often yes, if the renovation is significant (structural work, a full rewire, major extension) β many unoccupied property insurers exclude cover for damage caused by or during substantial building work unless you specifically declare the works and, in some cases, take out renovation-specific cover or a contractor's all-risks policy alongside it.
What happens if I don't tell my insurer the property is empty for renovation?
If a claim arises and the insurer discovers the property was unoccupied beyond their policy's limit, or undergoing works you didn't declare, they can refuse the claim entirely or reduce the payout, even if the cause of the damage was unrelated to the works themselves β non-disclosure is a common reason claims are rejected.
Are there conditions I need to meet to keep unoccupied cover valid?
Common conditions include regular inspections (often weekly or fortnightly, with records kept), the water supply being turned off at the mains if not needed for works, alarm systems being maintained and active, and the property being kept secure (all doors and windows locked, no obvious signs of vacancy).
Does my mortgage lender need to know the property will be empty during renovation?
Many buy-to-let mortgage terms require the lender to be notified if a property will be unoccupied for an extended period, particularly during renovation, since it affects the risk profile of their security. Check your mortgage terms and notify the lender if required, to avoid a technical breach of your mortgage conditions.
How long can a rental property typically stay empty before insurance becomes a problem?
Most standard landlord policies set the threshold at 30 or 60 days of continuous vacancy, after which cover is automatically restricted or void unless you've arranged specific unoccupied property cover in advance β always check your specific policy wording rather than assuming a standard threshold applies.
Is it worth doing renovation work with tenants still living there instead?
Sometimes, for minor works, but significant renovation with tenants in situ carries its own risks β disruption claims, habitability issues, and potential breach of the tenant's right to quiet enjoyment of the property β so for major works, vacating the property and arranging appropriate unoccupied cover is often the safer and more practical route despite the higher insurance cost and lost rent.
