| — | Stage | What happens | Timing |
|---|---|---|---|
| 01 | Confidential enquiry | The line, the holding and the objective, shared through a secure channel. | Day one |
| 02 | Pricing the block | The line is sized and a price set against it; any discount reflects size and liquidity. | 1–2 days |
| 03 | Execution & print | Worked off the order book or negotiated, then printed under the exchange’s block-trade rules. | On the day |
| 04 | Settlement & disclosure | Settles on the standard cycle; any substantial-holding disclosure is sequenced around the print. | T+1 / T+2 |
United Kingdom equity markets.
A UK block trade moves a large line of London-listed stock in a single negotiated transaction — off the order book, at an agreed price — so a holder can exit, or an acquirer build a position, without walking the screen. Black Haven can take the line onto its own book, giving the seller a clean, priced exit while the off-book trade report and any disclosure that follows a substantial transfer are managed around the print.
A block is reported off-book rather than routed through the order book, and under the UK trade-transparency regime inherited from MiFID II a large-in-scale trade can qualify for deferred publication — so the print need not hit the tape immediately, limiting market impact while the transfer settles. Size is read against average daily turnover: a FTSE 100 line absorbs a large clip comfortably, while the same size in an AIM or small-cap name moves the price and is worked more carefully. If the trade takes either side through a DTR 5 threshold, the 3%-and-each-point notification to the issuer and the FCA follows. Settlement runs T+2 through CREST.

What Is a Block Trade, and How Does One Work?
A block trade is the off-market sale of a large line of listed shares at a negotiated price, executed bilaterally and printed under exchange rules to avoid moving the open market.
Read → Block TradesHow Do You Sell a Large Block of Shares Without Moving the Price?
A large block is sold without moving the price by taking it off the open order book — negotiating off-market at an agreed price, often with a liquidity provider taking the risk, and printing under exchange block rules.
Read → DisclosureDo Block Trades Have to Be Disclosed?
Often yes. Once a significant shareholder crosses a market’s substantial-holding threshold, a block sale is generally notifiable to the regulator within a set window, with thresholds varying by jurisdiction.
