What other fees or costs might I have to pay?
When buying a property at auction, the purchase price is only part of the total cost. Many auction properties come with additional fees and financial obligations, some of which are set out in the small print of the special conditions in the auction contract.
These extra costs are legally binding — even if you didn’t read them — and must be paid in addition to the purchase price.
Common additional costs include:
Auctioneer’s administration fee
Most auction houses charge a non-refundable admin fee, often between £500 and £1,500 plus VAT, payable on the day of the auction.
Seller’s legal fees
Some sellers pass on part or all of their legal costs to the buyer. This can include:
- Their solicitor’s fees for preparing the legal pack
- Search fees and other disbursements
- Contribution towards completion costs
Buyer’s Premium
Some auctions add a “Buyer’s Premium” on top of the hammer price — typically a fixed amount or percentage (e.g. 1.2% of the purchase price).
Apportioned sums
You may have to pay a share of:
- Ground rent or service charges (for leasehold)
- Insurance premiums
- Rent (if there is a tenancy)
VAT
Some commercial or mixed-use properties attract VAT on the sale price. If so, this will be in addition to your winning bid.
