Auction Property Insurance UK | Cover From the Hammer
Auction property insurance protects buyers of property bought at auction from the moment they become responsible for it. At most UK auctions, contracts are exchanged when the hammer falls, and under the common auction conditions the risk usually passes to the buyer at that point, even though completion may be 28 days or more away. That means you need buildings cover and property owners' liability straight away. Many auction lots are empty, in poor condition or non-standard, so standard home and landlord policies often decline them. Bridging lenders usually require cover with their interest noted before completion. Insurers look at the property's condition, occupancy, construction, location and your plans, such as letting, refurbishment or resale.
Key facts at a glance
- Risk usually passes at the hammer. Under common auction conditions, the buyer normally bears the risk from exchange, not completion.
- Lenders need cover first. Bridging lenders usually require insurance with their interest noted before they complete.
- Many lots are empty. Unoccupied property needs specialist cover with security and inspection conditions.
- Non-standard lots are common. Auctions attract properties with subsidence, knotweed, RAAC or unusual construction.
- Your plans shape the cover. Letting, refurbishing and reselling each need a different policy.
When do you need to insure an auction property?
At most UK auctions you exchange contracts when the hammer falls. Under the common auction conditions the risk usually passes to you at that point, so you need cover from the day of the auction, not completion.
Always check the special conditions in the legal pack, because some sellers keep the property insured until completion and others do not. If the building burns down between exchange and completion, you could still have to complete the purchase.
Speak to us before you bid so cover can start the moment you win. Waiting until after the auction can leave a gap.
What insurance does an auction property need?
Most auction properties need buildings cover, property owners' liability and, if empty, unoccupied property cover. If you plan works, you also need contract works and existing structures cover.
| Situation | Cover needed |
|---|---|
| Empty and awaiting works | Unoccupied property cover and owners' liability |
| Tenanted at purchase | Landlord buildings cover, liability and loss of rent |
| Under refurbishment | Contract works plus existing structures cover |
| Derelict or unsafe | Derelict building cover with liability |
| Commercial or mixed-use | Commercial property cover |
Non-standard auction lots
Auction lots often have issues that put off mainstream insurers and mortgage lenders. Specialist markets can usually cover them.
Common problems include past subsidence, Japanese knotweed, RAAC, non-standard construction, thatched roofs and listed status. See our guides to subsidence history property insurance, Japanese knotweed property insurance and RAAC property insurance.
What do insurers ask about an auction property?
Insurers ask about the property, its condition and occupancy, the auction and completion dates, your lender and your plans.
- Property. Address, type, construction and age
- Condition. Survey findings, photos and known defects
- Occupancy. Empty, tenanted or partly occupied
- Dates. Auction, exchange and completion
- Finance. Lender name and requirements
- Plans. Let, refurbish, convert or resell
