FTSE 250 list of companies: where the official list lives and how to read it
FTSE Russell, part of LSEG, owns the FTSE 250, and the London Stock Exchange shows its constituents in a live table. The list is reviewed every quarter, so any copy saved before the latest review may be out of date.
Short answer: use the live constituents table on the London Stock Exchange website, and check the date of the most recent FTSE Russell quarterly review before you trust any other copy. This post does not reproduce the list, because a reproduced list is the thing that goes stale.
Where the official FTSE 250 list is published
Two primary sources matter. Everything else is a copy of one of them.
- FTSE Russell (part of LSEG) owns the index. Its FTSE UK Index Series page describes the FTSE 250 as mid-capitalised companies not covered by the FTSE 100. FTSE Russell also publishes the ground rules that decide membership and the results of each review.
- The London Stock Exchange shows the members. On londonstockexchange.com, go to Indices, FTSE 250, Constituents, then Table. The same section also has Risers and Fallers and a Heatmap view, which are price views, not the list itself.
For what the index is and why it exists, see the guide to the FTSE 250. This post covers only how to find the list and how to read it.
How to read a constituents table
The London Stock Exchange's own help text explains each column. In the FTSE 250 table you will see:
- Code: a short, unique code that identifies a UK-listed security, also called the TIDM or ticker. Clicking it opens the company's profile.
- Name: the security's full name as listed. This often includes the share class, such as "ORD 10P", so it reads differently from the brand name you know.
- Currency: the currency the price is quoted in. GBX means pence, not pounds.
- Market cap (m): the issuer's market capitalisation in millions of pounds.
- Price, Change and Change %: the latest price and the move since the last close.
There is no sector column. To find a company's industry, open its profile from the Code or Name link.
Two habits help. First, the table is sorted by daily change % by default, so the order tells you about today's price moves, not about size or membership. Sort by Name or Code if you want a steady list to scan. Second, treat the Price and Change columns as live market data that changes all day. The membership is the stable part; the numbers next to it are not.
Why a copied FTSE 250 list goes out of date
A list is a snapshot, and the index keeps moving.
When someone pastes the table into a blog post, a spreadsheet or a forum thread, it stays exactly as it was on that day. The official list changes at every quarterly review, and companies can also leave between reviews because of corporate actions such as takeovers. FTSE Russell handles these under its separate Corporate Actions and Events Guide. A copy that looked right when it was made can be wrong a few weeks later, and nothing on the page will show it.
That is also why two pages that both look official can disagree. Each one has stopped at a different date.
How the quarterly review changes the list
According to the FTSE UK Index Series ground rules:
- The series is reviewed every quarter, in March, June, September and December.
- Eligible companies on the London Stock Exchange's Main Market are ranked by full market capitalisation, using data taken at the end of the day on the Tuesday before the first Friday of the review month.
- A company joins the FTSE 250 if it rises to 325th or above, and leaves if it falls to 376th or below. These buffers stop companies near the edge from moving in and out every quarter.
- A company that drops out of the FTSE 100 normally moves into the FTSE 250, and a company promoted to the FTSE 100 leaves the FTSE 250.
- Changes take effect after the close of business on the third Friday of the review month, so they apply from the following Monday.
FTSE Russell publishes the result of each review. For a saved list, that means:
- Write the date on any list you save.
- Note the next review month. After September, it is December.
- After the changes take effect, check your list against the live London Stock Exchange table.
How the FTSE 250 list differs from the FTSE 100 list
You find both lists the same way. The London Stock Exchange has a constituents table for each, with the same columns. The differences are what each list contains and how sensitive it is to the review:
- The FTSE 100 holds the most highly capitalised companies. The FTSE 250 holds the mid-sized companies ranked below them.
- A company crossing the boundary changes both lists at once. Promotion to the FTSE 100 removes it from the FTSE 250, and demotion normally moves it the other way. If you can't find a company in one table, check the other.
- Because the FTSE 250 has two edges, one shared with the FTSE 100 and one shared with the FTSE SmallCap, a review can change it at both ends.
The FTSE 100 index guide explains the larger index.
Following company news once you have the list
A list tells you who is in the index. It doesn't tell you what is happening to those companies.
MarketFrame covers FTSE 100 companies only, so it has no FTSE 250 coverage. For FTSE 100 companies, the daily FTSE news hub scores the tone of each morning's coverage. Each company and sector also has its own history page, listed under FTSE news analysis, going back to 30 September 2026.
News tone is not a share-price forecast. A run of positive coverage does not mean a share will rise, and a run of negative coverage does not mean it will fall. Use tone to see what is being reported about a company, not to predict where its price will go.
A short checklist for any index list you find online
Before you rely on a list, check:
- Does it name its source, either FTSE Russell or the London Stock Exchange?
- Does it show the date it was taken?
- Has a quarterly review taken effect since that date?
- Does it still match the live London Stock Exchange table?
- Is it actually a list of members, or a page of prices and commentary?
If any answer is no, or you can't tell, go back to the live table.
Questions people ask
Where can I find the official list of FTSE 250 companies?
The London Stock Exchange shows it as a live table under FTSE 250, Constituents, Table on londonstockexchange.com. FTSE Russell, part of LSEG, owns the index and publishes the rules and review results that decide who is on it.
How often does the list of FTSE 250 companies change?
FTSE Russell reviews the FTSE UK Index Series every quarter, in March, June, September and December. Changes take effect after the close on the third Friday of the review month. Companies can also leave between reviews because of corporate actions such as takeovers, which FTSE Russell handles under separate rules.
Why do two FTSE 250 lists I found online not match?
Usually because they were copied at different times, with a quarterly review or a corporate action in between. Check both against the live London Stock Exchange table.
Is a FTSE 250 company a smaller or riskier company than a FTSE 100 one?
It is smaller by full market capitalisation at the last review, because the FTSE 250 covers mid-sized companies outside the FTSE 100. Membership tells you nothing about a company's risk or prospects, and this is general information, not investment advice.
Does MarketFrame cover FTSE 250 companies?
No. MarketFrame covers FTSE 100 companies only, with daily news-tone pages from 30 September 2026. For FTSE 250 companies, go to the London Stock Exchange and FTSE Russell sources described above.
