KP Law Limited is a London-based British law firm specializing in group litigation and collective-redress. The firm represents consumers and other claimants in cases involving product liability, workers’ rights, data breaches and privacy, investment and financial fraud, mis-selling, and competition law. The firm operates largely on a "no win, no fee" basis and is regulated by the Solicitors Regulation Authority.

KP Law was formed in its current structure in March 2024 following the merger of Keller Postman UK Limited with Lanier, Longstaff, Hedar & Roberts LLP, the UK arm of the US firm led by trial lawyer Mark Lanier. It ownership is linked to the litigation funder Asertis.

History

Origins

The firm's lineage runs through the UK arm of the American mass-tort practice Keller Postman. According to company-database records, it was founded in 2019 as Keller Lenkner UK but later renamed Keller Postman UK. A commentary by the law firm Weightmans describes KP Law similarly as formerly known as Keller Lenkner UK Ltd. and Keller Postman UK Ltd. Under the Keller Postman UK banner the practice built a portfolio of group actions including diesel-emissions claims against Volkswagen, workers' rights claims against Uber, and data-breach claims.

The 2024 merger and rebrand

In March 2024, Keller Postman UK merged with Lanier, Longstaff, Hedar & Roberts (LLHR) forming a specialist collective-redress firm practicizing as KP Law Limited. According to Legal Futures, the new firm launched with six partners and 14 other lawyers, covering areas including product liability, workers' rights, data breach and privacy, investment fraud and financial-products mis-selling, and competition law. The Global Legal Post reported that four Keller Postman UK partners, led by Andrew Nugent Smith, joined the LLHR founding partners, barristers Tom Longstaff and Duncan Hedar, who took the heads of product liability and competition respectively.

KP Law cut its ties with Keller Postman in the United States, while retaining a relationship with LLHR's sister firm, The Lanier Law Firm, handling its cases in the UK and Europe - notably the talcum-powder litigation against Johnson & Johnson. The announcement came just a day after the government signaled legislation to ease third-party funding of collective litigation following a UK Supreme Court judgment on litigation funding.

Ownership and the Legatus restructure

The Global Legal Post reported that Asertis acquired the entire issued share capital of Keller Postman UK on 1 January 2024, after the company refinanced its debt in mid-2023, and that the business changed its name to KP Law on 4 March 2024. Bloomberg Law reported that Asertis had bought Keller Postman UK in 2023 and acquired LLHR the following year, and that KP Law was the result of the 2024 merger of the two firms' UK divisions.

In early 2025 Legal Futures reported a corporate reorganization in which Asertis, KP Law and newly created insurance and claimant-acquisition companies were brought under a holding company, Legatus Holdings. KP Law's Duncan Hedar became chief executive of Asertis while remaining the firm's head of competition, and Andrew Nugent Smith continued to lead KP Law. Legal Futures also reported that Asertis is funded by the alternative asset manager Arrow Global and by funds managed by AB CarVal. Bloomberg Law noted that such funder-owned alternative business structures are permitted in England and Wales but are far less common in the United States, where many states bar non-lawyer ownership of law firms.

Practice areas

The Law Society Gazette described KP Law at launch as a "no win, no fee specialist" in the collective-redress sector. The firm handles large-scale consumer claims involving areas like product liability, workers' rights, data breach and privacy, investment fraud and financial mis-selling, and competition law. KP Law is also a founding member of the Collective Redress Lawyers Association (CORLA).

Notable matters

Harrods / Al Fayed survivors

KP Law represents more than 260 survivors bringing abuse claims connected to the late Harrods owner Mohamed Al Fayed. PA Media reported that the firm had criticised Harrods’ own redress scheme, including concerns that the retailer retained “complete control” over the process. In December 2025, the Solicitors Journal reported that KP Law had negotiated alternative settlement arrangements with Harrods and the Al Fayed estate. The arrangements were described as more trauma-informed and survivor-centred, following criticism of the original scheme.

KP Law’s approach to fees has also been the subject of criticism. In April 2025 the Retail Gazette, citing Sky News, reported that Harrods had asked the firm to reconsider a proposal under which it could receive up to 25% of claimants’ compensation in fees. The report said this could amount to tens of thousands of pounds per claimant and noted that some other firms representing survivors had agreed not to take a percentage of compensation. KP Law said its fees reflected the work involved in supporting clients through the litigation and seeking to recover the maximum possible damages.

Other litigation

Reporting on the merger noted that the firm’s work includes a range of ongoing and inherited group actions. These include claims relating to diesel emissions, workers’ rights, data breaches and equal pay, as well as a competition claim concerning Google's advertising practices. The firm also continued the Johnson & Johnson talc litigation that came across from the Lanier side of the merger.

Regulatory scrutiny of advertising

In September 2025, the Advertising Standards Authority (ASA) issued a series of rulings concerning the marketing of group-action claims, following complaints from the lobby group Fair Civil Justice. The Law Society Gazette reported that the ASA had investigated Johnson Law Group, Jones Whyte Law and KP Law, all of which are regulated by the SRA. The rulings addressed claims about potential compensation and the use of “no win, no fee” wording, and were expected to inform the SRA’s wider investigation into marketing practices in the sector.

The ASA’s ruling on KP Law concerned advertising for a lead-generation service called “Join the Claim”. The regulator found that the advertising did not make sufficiently clear that the service generated leads for sale to law firms. One example involved leads relating to the Arnold Clark data breach that were intended for KP Law. The ASA concluded that the lack of clarity about the service’s commercial purpose was misleading. CMS noted that the ruling focused specifically on the “Join the Claim” website and advertising, while separate ASA rulings involving other firms dealt with issues including fee information and “no win, no fee” claims.

The SRA was also taking a broader look at marketing in high-volume claims. In September 2025, the Law Society Gazette reported that the regulator had promised “robust action” against misleading “no win, no fee” advertising, including in areas such as data-breach and diesel-emissions claims. The SRA was also considering new requirements covering marketing, advertising and the process of taking on clients.

Finances

The Global Legal Post reported that Keller Postman UK's most recent accounts before the merger, as of 31 December 2023, showed current assets of approximately £7.9 million and net current liabilities of about £37 million, which means an increase of around £9.6 million on the 2021 position.
