Selling Art Through Auction: What You Need to Know

Whether you have a single painting you've inherited, a collection you're downsizing, or original art you've created yourself — UK online auction is one of the most effective ways to sell it.

This guide covers everything: how the process works, what sells well, how art is valued before a sale, and what to expect in terms of fees and timelines.

What Sells at Art Auction in the UK?

A broader range of art sells at auction than most people realise. The most common categories include:

Original paintings — oils, watercolours, acrylics. Both framed and unframed. Condition and artist provenance matter significantly
Limited edition prints — signed and numbered prints in good condition, preferably with certificates of authenticity
Photography prints — fine art photography, particularly signed limited editions
Sculpture and ceramics — decorative and fine art pieces in good condition
Antique and vintage works — Victorian and Edwardian oils, watercolours, prints and engravings are consistently in demand
Contemporary art — original work from emerging and established contemporary artists

Work that is in good condition, has a clear provenance, and comes with any available documentation (certificates, artist notes, exhibition records) will always sell more strongly than equivalent pieces without these.

How the Selling Process Works

The typical process for selling art at a UK online auction house:

Submit for appraisal — send photos and details (dimensions, medium, artist, condition) to the auction house for an initial assessment
Agree on lot details — the auction house sets a suggested estimate and reserve price based on comparable sales and current market demand
Cataloguing — your piece is photographed, written up and listed in the appropriate sale
The auction runs — bidders compete over a set period (typically several days for online auctions)
Payment — once the buyer pays, you receive the hammer price minus the seller's commission

Understanding Reserves and Estimates

A reserve price is the minimum amount a piece must reach before it can be sold. If bidding doesn't reach the reserve, the piece is unsold and returned to you.

An estimate is a guide range showing what the auction house expects the piece to sell for based on market conditions. This is used in the lot listing and marketing.

Setting the reserve too high reduces the chance of a sale. Most experienced sellers accept a modest reserve and let genuine market demand determine the final price — often with strong results.

Seller Fees: What to Look For

Different auction houses structure their fees differently. The main things to understand:

Seller's commission — a percentage of the hammer price taken by the auction house. This varies widely, from 0% at some platforms to 20%+ at others
Photography and catalogue fees — some houses charge for listing or photography. Always ask upfront
Unsold fees — some auction houses charge a fee if your lot doesn't sell. Check this before consigning
Transport and insurance — for physical consignment, who bears the cost of delivering the piece to the auction house?

At William George, seller commission is 0% — you keep the full hammer price. There are no listing fees and no fees if the piece doesn't sell.

How Art is Valued Before a Sale

Art valuation before auction considers several factors:

The artist — known artists with exhibition histories and strong secondary market sales command higher estimates
Medium and size — original oils typically command more than prints; larger format works can command premiums but are also harder to place
Condition — any restoration, damage, fading or canvas issues will affect value. Honest condition reporting builds buyer trust
Provenance — documented ownership history, exhibition records, certificates and artist notes all add value
Comparable sales — what similar work by the same or similar artists has achieved at auction recently

Tips for Getting the Best Result

Photograph clearly — good images of the front, back, signature, and any damage help buyers bid with confidence
Include all documentation — certificates, artist letters, exhibition labels, and any written provenance you have
Be honest about condition — overstating condition damages trust and can lead to disputes post-sale
Choose the right sale — a painting is more likely to sell well in a dedicated art auction than mixed with general household lots
