PropertyAuctions.live

In development

Every property auction in the UK and Ireland, and the software that runs them.

One search across every auction house instead of twenty, and the system underneath it running the sale for the house selling the lot. The same thing seen from either end.

Join the listSee what we’re building

The platform is built and running against sample data. What comes next is the first auction house and the first sale in the diary — join the list and we will write on the day one is set.

The aggregator home page: a search bar over a sale running live now, followed by the auction diary listing four forthcoming sales with dates, lot counts and the auction house running each.
Running today The aggregator as it stands today, running against sample data.

What we’re building

Three surfaces on one engine. Some of what follows is a photograph of software running today; the rest is the design of what is being built next. Every picture says which, so you always know exactly what you are looking at.

One search, every auction house

Built. Running now against sample data.

Twenty auction houses publish twenty catalogues, in twenty formats, on twenty different weeks. The first thing we built reads all of them and puts the answer in one list.

Watch any sale here, without an account. Bidding stays with the auction house, on their own site and under their contract, and that is deliberate.

  • Search the way the trade searchesTown, postcode, lot type, guide range and tenure.
  • One diary, every houseEach forthcoming sale from each listed auction house, in date order.
  • Method of sale, statedUnconditional, conditional or private treaty — on every lot, before you commit.
  • What winning really costsHammer price, buyer's premium and admin fee, added up for you.
  • Watch without an accountLive sales are open to anyone. No sign-up, no fee.
  • Straight through to the houseEvery lot links out to the auction house selling it, in one click.
  • Residential
  • Residential investment
  • HMO
  • Commercial
  • Mixed use
  • Land
  • Garage
  • Ground rents
Search results with a filter rail on the left for location, guide price, lot type and tenure, and six lot cards on the right, each showing a photograph, address, guide price and the auction house selling it.
Running today Search across every listed lot, filtered rather than browsed.
A lot page showing the property photograph, address, guide price, particulars and a breakdown of the total cost of winning at the guide, with a link out to the auction house selling it.
Running today A lot, and what winning it would actually cost.

The auction house's own site

Where the sale actually happens

Built and running. Two of the four screens below are in design.

White label, and we mean it literally. The auction house's name, domain, colours and terms. Bidders register with them, pay them, and never see us.

The bid path is where most of the work went — because it is the part where being nearly right is the same as being wrong.

  • Register once, not once a saleIdentity, address and sanctions checks, on a phone, in about five minutes.
  • Deposits held, not takenReleased the moment they can no longer secure anything.
  • Bids that survive a bad lineSaved before they are acknowledged, ordered by the server, safe to retry.
  • No bidding on a stale priceA bid against a price that has already moved is refused rather than guessed at.
  • The reserve stays at the rostrumYou are told how close the bidding is. You are never sent the number.
  • Changed lots are gatedAn addendum has to be read before that lot can be bid on again.
A lot page on an auction house's own site, showing photographs, the guide price, tenure, EPC rating, viewing dates and the legal pack download.
Running today A lot page, in the auction house's brand rather than ours.
An auction catalogue listing lots in order of sale, each with a photograph, lot number, address, guide price and current status.
Running today The catalogue, in order of sale.
The registration screen: identity and address verification steps, a deposit pre-authorisation, and a consent panel with contact about the lot required, marketing off by default, and sharing with other auctioneers permanently declined.
In design Registering to bid. The pipeline behind this screen already runs.
The bidder's live sale view: the video of the room, the current lot and price, the calling stage, a qualitative indicator of distance to reserve, the total cost of the next bid, and the bid button.
In design The live sale, with the cost of the next bid stated next to the button that places it.

The rostrum and the auction desk

What the auctioneer is looking at

The engine and sale control are built. The consoles are in design.

An auctioneer calling a room and a stream at once needs one screen, not two — and it has to keep working when the venue's broadband does not.

This is the only screen in the platform that shows a reserve, and it does not leave here.

  • Distance to reserveHow far off it is, how many increments clear it, and how fast the room is moving.
  • Every bid labelled by sourceRoom, telephone or vendor — recorded as such in the audit log.
  • See the line before it dropsUplink telemetry, so a degrading connection is visible while there is time.
  • Started by a personNever by a clock, and never at all unless the sale can actually be run.
  • Rehearsal modeMoves no money, and can never be mistaken for a real sale.
  • Audited end to endEvery change of state written into the sale's own hash chain.
The auctioneer's rostrum: the current lot and bid, a bar showing the distance from the current price to the reserve, the increments needed to clear it, and controls for room bid, phone bid, vendor bid, pause and hammer.
In design The rostrum. The reserve appears here and nowhere else in the platform.
The auction desk: a list of registered bidders with their verification and deposit status, the catalogue in order of sale, and the controls to start, pause and end the sale.
In design The auction desk, where the sale is assembled before it is run.

Guarantees, not intentions

Each of these is written into the specification as a requirement rather than kept as a policy we could quietly change later, which is why we can state them this plainly.

  • We never hold contract money.Deposits and completion monies go to the auction house's client account. We are not a payment institution, and the architecture is not allowed to make us one by accident.
  • We never take a bid on the aggregator.Bidding belongs to the auction house, on their site, under their terms.
  • We never share a bidder between auction houses.No cross-tenant use of anybody's data, and no shared marketing list.
  • We never put our name on the buyer's paperwork.Not on the invoice, and not in the contract they sign.
  • We never show a reserve outside the rostrum.Not to a bidder, not to the aggregator, and not into a log.

Where we are today

The bidding engine, the catalogue, the registration pipeline and the auctioneer’s sale control are all built and running. The hard part is behind us, and it was deliberately the part nobody enjoys building.

What comes next is the first auction house and the first sale in the diary. That is the email you will get: one message, on the day a real sale is scheduled.
