There are several ways to sell a home in the UK, but the two most common are a private sale through an estate agent and a sale at auction. Both have their own advantages and drawbacks — the key is to pick the right route for your situation. The wrong decision can cost you not only time, but thousands of pounds. In this guide we explain how each method works, who it suits and how to decide.
How does a private sale work?
This is the most common route. The home is sold through an estate agent, and the process usually looks like this:
- The listing goes up on the major portals — Rightmove, Zoopla, OnTheMarket.
- Buyers register for viewings and put forward offers.
- Price and terms are agreed through negotiation.
- The process can take anywhere from 2 to 6 months, depending on the market.
The biggest advantage is reach — you get in front of a wide audience, including families who plan to live in the home themselves. Buyers like that are often willing to pay more than investors, so a private sale usually achieves a higher final price. You also have more time to prepare, get the property looking its best and sort out the paperwork.
The flip side is that the process is longer and less predictable. Sales often stall because of chains, buyers may negotiate hard and try to chip the price, and in the worst case a deal collapses well into the process. More on chains and chain-free selling →
How does an auction work?
Auction is a faster, more structured route. The home is sold through a specialist auction house:
- The property is entered into a catalogue and marketed ahead of the auction.
- Buyers bid against each other, either in the room or online.
- The winning buyer exchanges on the day and pays the full balance within 28 days.
The main advantage of auction is speed and certainty. You typically have the money within about a month, and the sale is locked in: the moment the hammer falls, the buyer can no longer pull out. Auction also works well when a home has problems that make it hard to sell on the open market — for example a short lease or major works needed.
The drawbacks are just as clear: the price is usually lower, the audience is narrower (mostly investors), and the auction house has to be paid commission — typically around 2–3% of the sale price.
Auction vs private sale — a comparison
Here are the key differences at a glance:
| Criterion | Auction | Private sale |
|---|---|---|
| Timescale | ~28 days | 2–6 months |
| Price | Usually lower | Usually higher |
| Certainty of sale | Locked in (hammer = final) | Risk of falling through |
| Audience | Narrow — mostly investors | Wide — families and investors |
| Best suited to | Defects, short lease, in need of works | Tidy, family-ready homes |
| Extra fees | Auction commission ~2–3% | Standard agent and legal fees |
When should you choose a private sale?
- You have time. If you're not in a rush, you can hold out calmly for the best offer.
- The home is in good order. Buyers are happy to pay more for a well-kept, move-in-ready property.
- You want maximum value. If selling for the highest possible price matters most, a private sale is usually the better route.
When should you choose auction?
- You need to sell quickly. If you need the money within a few weeks — to clear debts or fund a new investment — auction is the fastest route. More on selling your home fast →
- The home has problems. Investors often buy properties with issues: a short lease, structural problems or the need for major renovation.
- You want a guaranteed sale. The moment the hammer falls, the deal is final and the buyer can't walk away.
If the home is standard, tidy and appealing to families, it's almost always worth choosing a private sale: it achieves a higher price. If the home has defects, you need to move fast, or it's purely an investment property, auction is often the smarter and safer choice.
A real example
A flat in London with just 55 years left on the lease. On the open market, flats like this sit for months on end, because lenders are reluctant to offer mortgages to their buyers — so genuine offers are few and far between.
- The solution: the flat went to auction and sold to an investor, for whom the short lease was no obstacle.
- The result: instead of waiting six months, the money was in hand within 28 days.
Auction — speed and a guaranteed sale, but usually a lower price. Private sale — a higher price, but a longer road and more risk.
Quick reference
- Choosing price and you have time? Private sale.
- Choosing speed and certainty? Auction.
- A home with problems, or an investment? Auction usually fits better.
The final choice comes down to your goals, the time you have and the condition of the home. A good agent will help you weigh up both routes honestly before you decide. Back to all guides →
