The top private equity law firms in London for large buyouts are Clifford Chance, Freshfields, Kirkland & Ellis, Latham & Watkins and Weil. All five sit in tier 1 of The Legal 500 UK 2027 table for private equity deals of £500m and above.
If you are a sponsor picking counsel, a lawyer moving firms or a banker learning who sits across the table, these are the names you will see on most large London deals. Below the top tier, the order changes depending on which directory you read.
This guide ranks 13 firms, shows both main directories side by side and explains how to use the list.
We rank each firm by its tier in The Legal 500 UK 2027 table for London private equity transactions valued at £500m and above, published on 30 September 2026. Firms in the same tier are listed alphabetically, because the directory does not rank within a tier.
Next to it we show the firm’s band in the Chambers UK 2027 table for private equity buyouts of £500m and above, released in October 2026. Two mid-market specialists are ranked by their tier in the Legal 500 table for deals up to £500m.
Both guides are legal directories (annual rankings built from client and peer interviews plus deal submissions). Tier 1 and band 1 are the top grades in each.
| Firm | Type | Legal 500 tier (£500m+) | Chambers band (£500m+) | Legal 500 tier (up to £500m) |
|---|---|---|---|---|
| Clifford Chance | Magic Circle | 1 | 1 | Not ranked |
| Freshfields | Magic Circle | 1 | 1 | Not ranked |
| Kirkland & Ellis | US firm | 1 | 1 | Not ranked |
| Latham & Watkins | US firm | 1 | 1 | Not ranked |
| Weil, Gotshal & Manges | US firm | 1 | 2 | Not ranked |
| Linklaters | Magic Circle | 2 | 1 | Not ranked |
| Simpson Thacher & Bartlett | US firm | 2 | 1 | Not ranked |
| Paul, Weiss | US firm | 3 | 2 | Not ranked |
| Skadden | US firm | 3 | 2 | Not ranked |
| White & Case | US firm | 3 | 3 | Not ranked |
| A&O Shearman | Magic Circle | 4 | 2 | Not ranked |
| Goodwin | Mid-market specialist | 5 | Not ranked | 1 |
| Macfarlanes | Mid-market specialist | Not ranked | Not ranked | 1 |
The two directories agree on four firms at the very top. They split on Weil, Linklaters and Simpson Thacher, which each hold a top grade in one guide and the second grade in the other.
The Magic Circle is the group of large London-headquartered firms. Their private equity teams sit next to big public M&A, finance and competition practices, which helps on take-privates of listed UK companies.
Clifford Chance is tier 1 in The Legal 500 and band 1 in Chambers. The Legal 500 names Spencer Baylin as practice head and lists Permira, Blackstone, Cinven, CVC, EQT, KKR and Carlyle among its key clients.
In September 2026, Nonbillable reported that a team led by Baylin advised EQT on its roughly $2bn majority buyout of London insurance broker McGill from Warburg Pincus. The firm also hired Bruce Embley from Skadden, a former co-head of global M&A at Freshfields.
Freshfields is tier 1 and band 1. The Legal 500 names Charles Hayes and Victoria Sigeti as practice heads and points to strength in technology, healthcare, financial services and sports deals.
Freshfields often sits on the target or seller side as well as with sponsors. It advised McGill and Warburg Pincus on the EQT sale in September 2026, and Nonbillable reported in April 2026 that it was advising Blackstone on the £1.4bn take-private of London-listed Senior.
Linklaters is tier 2 in The Legal 500 and band 1 in Chambers. Alex Woodward is in The Legal 500 Hall of Fame (its top grade for individual partners), and Tracey Lochhead and Ben Rodham are leading partners.
Nonbillable reported that on the £1.4bn Senior bid in April 2026, Linklaters was lead legal adviser to the Blackstone and Tinicum consortium, with a team led by Alex Lehtinen and Iain Fenn. It also acted for Platinum Ivy, part of the CVC, Nordic Capital and ADIA consortium that completed the £5.4bn Hargreaves Lansdown takeover in March 2025.
A&O Shearman is tier 4 in The Legal 500 but band 2 in Chambers, one of the widest gaps between the two guides on this list. Stephen Lloyd is in The Legal 500 Hall of Fame for large private equity deals.
The firm is a good example of why you should read both directories before drawing a conclusion about a practice.
US firms hold four of the seven places in the top two Legal 500 tiers. Several have grown their London teams by hiring senior partners from rivals, as the Paul, Weiss entry below shows.
Kirkland & Ellis is tier 1 and band 1. Kirkland reported on 15 October 2026 that Chambers UK 2027 ranks it band 1 in four private equity tables, covering buyouts, private equity funds, credit funds and secondaries.
Kirkland also reported on 1 October 2026 that it holds nine tier 1 rankings in The Legal 500 UK 2027. Matthew Elliott, David Higgins and Adrian Maguire are in the Hall of Fame. On Hargreaves Lansdown it advised the bid vehicle and Nordic Capital.
Latham & Watkins is tier 1 and band 1. Latham reported on 30 September 2026 that it holds 44 UK rankings in The Legal 500 UK 2027, 18 of them tier 1.
It has four partners in the Hall of Fame for large private equity deals: Paul Dolman, Tom Evans, Kem Ihenacho and David Walker. That is more than any other firm in the table. Latham acted for CVC on Hargreaves Lansdown.
Weil is tier 1 in The Legal 500 and band 2 in Chambers. Marco Compagnoni is in the Hall of Fame, and Lewis Blakey, Max Oppenheimer and Jonathan Wood are leading partners.
Weil said on 15 October 2026 that Chambers UK 2027 ranks its London office in 14 practice areas, with 26 individual lawyer rankings.
Simpson Thacher is tier 2 in The Legal 500 and band 1 in Chambers. The firm reported on 15 October 2026 that Chambers UK ranks it first for private equity buyouts of £500m and above and for private equity funds.
The Legal 500 lists Clare Gaskell, Wheatly MacNamara and Amy Mahon as leading partners. On the Senior bid, Simpson Thacher gave regulatory advice to Blackstone.
Paul, Weiss is tier 3 in The Legal 500 and band 2 in Chambers. Its London team grew quickly in 2023, when Law.com reported that private equity partners Roger Johnson and Andreas Philipson joined from Kirkland.
Johnson is now in The Legal 500 Hall of Fame, and David Holdsworth and Christopher Sullivan are leading partners.
Skadden is tier 3 and band 2. Richard Youle is in The Legal 500 Hall of Fame and Katja Butler is a leading partner for large private equity deals.
The firm lost Bruce Embley to Clifford Chance after several years, during which he advised Permira on the partial sale of Alter Domus to Cinven at a €4.9bn enterprise value.
White & Case is tier 3 and band 3. Helen Croke is in The Legal 500 Hall of Fame.
White & Case is strong where deal and debt meet. On Hargreaves Lansdown, Global Legal Post reported that it acted for the club of private credit funds that provided senior secured financing for the offer.
For buyouts under £500m, The Legal 500 ranks a different set of firms. Two of its tier 1 names also appear on large London deals.
Goodwin is tier 1 in The Legal 500 table for London deals up to £500m and also appears in tier 5 for deals above £500m. Nonbillable reported that it was one of the advisers to the Blackstone and Tinicum consortium and to Tinicum on the £1.4bn Senior bid in April 2026.
Macfarlanes is tier 1 in The Legal 500 table for London deals up to £500m. Global Legal Post reported that on Hargreaves Lansdown it advised founder Peter Hargreaves, who reinvested part of his stake alongside the buyers.
Other tier 1 firms in that mid-market table include Addleshaw Goddard and DLA Piper.
Start with deal size. A £2bn take-private needs a firm from the £500m+ table, while a £150m buyout of a founder-owned business is usually better served by a mid-market specialist.

If you are a candidate, the same tables show where the deal flow is. You can pair them with our guides to the top private equity firms in London and the top boutique investment banks in London to see who works with whom.
The core legal work on these deals covers the share purchase agreement, the financing documents and the legal due diligence. Our overview of the essential legal documents in M&A and our guide to private equity term sheets cover what each one does.
Clifford Chance, Freshfields, Kirkland & Ellis and Latham & Watkins hold the top grade in both The Legal 500 UK 2027 and Chambers UK 2027 for London private equity deals of £500m and above. Weil is also Legal 500 tier 1, and Linklaters and Simpson Thacher are Chambers band 1.
Both are annual legal directories that grade firms in tiers or bands using client feedback, peer interviews and deal submissions. They research separately, so the results differ. Weil is Legal 500 tier 1 but Chambers band 2, while Linklaters and Simpson Thacher show the reverse pattern for large London buyouts.
The Legal 500 UK 2027 table for London private equity deals up to £500m puts Addleshaw Goddard, DLA Piper, Goodwin and Macfarlanes in tier 1. Ashurst, Travers Smith, Osborne Clarke and Pinsent Masons are among the firms in tier 2 of the same table.
US firms hold four of the seven places in the top two Legal 500 tiers for London deals over £500m: Kirkland, Latham and Weil in tier 1 and Simpson Thacher in tier 2. Clifford Chance and Freshfields are the UK firms in tier 1, and Linklaters is in tier 2.
For large London buyouts, Clifford Chance, Freshfields, Kirkland, Latham and Weil form the top tier, with Linklaters and Simpson Thacher close behind. Read Legal 500 and Chambers together, match the firm to your deal size and check the named partners before you choose.
