What happens when a home goes on the market
The price cut is the visible part of a stalled listing. It is not the part that lasts.
01
You can cut the price. You can’t un-list.
A traditional listing creates a public record: the date it went up, the price that was tried, the day it came off. open for offer happens before that, and leaves none of it.
02
It can come back, with a history.
- Nearly 1 in 4
- 23.4% of listings had a sale fall through at least once (2026). The home goes back on the market with the first attempt still attached to it.TwentyCi
Over a third of new listings don’t go on to sell.
03
You only get one first day.
Both figures describe homes on the open market, advertised in the usual way.
22%more likely to secure a buyer
Homes that get an enquiry on their first day of marketing are 22% more likely to secure a buyer than homes that wait more than two weeks for their first enquiry.
Test the market first, and you arrive at day one with the price already settled.
Before the board goes up
The queue starts long before the board does.
Selling this year, next year or the year after: the queue can start now. Buyers can register interest in your home today, before you decide to test the market.
You decide if and when it becomes a sale, knowing what the interest looks like.

Questions people ask us
How do I find out what my house is worth without an estate agent?
You can get a free instant market estimate for any of about 14 million England and Wales homes we cover, by entering its postcode, with no agent visit and no email required to see the figure. The estimate is built from that home’s own last recorded Land Registry sale, indexed forward using market growth data, and is shown as a range with a confidence level and the date it was calculated. It is an automated estimate rather than a valuation or a survey, and it is no substitute for a professional valuation before you buy or sell.
Can I sell my house without listing it publicly?
Not through open for offer. You can see your market estimate and any interest buyers register in your home without listing it, and nothing is listed until you choose to test the market. Testing the market lists your home publicly as open for offer, with its address. There is no board, no viewings until you say so, and you never have to accept an offer.
Can I buy a house that isn’t on the market?
Yes. Any of about 14 million homes we cover in England and Wales has a page here, whether or not it is advertised for sale, and you can register interest in it. Your registration joins that home’s queue. Nothing happens to a home without its owner’s say-so, and no owner is ever under any obligation to respond. About 2% of homes in England and Wales are for sale at any one time, so most of the homes a buyer would actually want are never visible on a traditional portal.
What does it cost to test the market on open for offer?
Testing the market costs £9.99 a month — that is one customisable listing you run yourself, and you can cancel it yourself online at any time. Browsing, searching and getting a market estimate are free, and none of them needs an email address. You can instruct an estate agent at any time. We are not an estate agent and we charge you no fee when your home sells.
What is open for offer?
open for offer is a UK pre-market property marketplace for homeowners who are considering selling but are not ready to list. Homeowners can see a data-backed market estimate and any interest buyers register in their home without listing it, and can test the market, which lists the home publicly as open for offer, with its address. No owner is obliged to sell. Buyers can register interest in any of about 14 million homes in England and Wales that have a page here, including homes that are not for sale. Your registration joins that home's queue, and the queue never shows names.
Which areas does open for offer cover?
open for offer covers about 14 million homes in England and Wales — every home with a Land Registry sold-price record since 1995. Each of those has its own page you can search today. Homes that have not sold since 1995 are not in the data. Stamford in Lincolnshire is the launch market where we are building depth first, and we also cover Cambridge, Oxford, Marlow and Peterborough.
Do I need an estate agent to sell through open for offer?
No — you can run your own customisable listing and manage the sale yourself on open for offer for £9.99 a month. You can instruct an estate agent at any time. We are not an estate agent and we charge you no fee when your home sells.
