Andrew is a specialist in costs and litigation funding, and Head of the Costs Group at Hailsham Chambers. Called to the Bar in 1996, he has a national practice and extensive experience of complex and high-value disputes concerning the costs, funding and financial consequences of civil litigation.
He appears regularly in the Senior Courts Costs Office, High Court and Court of Appeal, as well as in the County Court. He is ranked Band 1 for Costs Litigation by Chambers UK and Tier 1 by the Legal 500.
Andrew acts for both paying and receiving parties. His practice encompasses costs arising from major commercial litigation, personal injury and clinical negligence claims, solicitor-client disputes, litigation funding, retainers, security for costs, non-party and wasted costs orders, Part 36 and QOCS.
Alongside his core costs and funding practice, Andrew undertakes related work in insurance coverage, complex credit hire litigation and claims management disputes and regulation. These areas frequently intersect with questions of funding, contractual liability, recoverability and the commercial arrangements through which civil claims are pursued.
The common theme of his practice is the cost, funding, insurance and commercial structure of civil litigation.
Andrew advises and appears in all aspects of contentious costs litigation. He is instructed at the outset of substantial litigation to advise upon costs strategy and risk, during proceedings on costs management and funding issues, and following judgment on the incidence, assessment and enforcement of costs.
His practice includes:
Costs management
Andrew appears at Costs and Case Management Conferences and advises in advance upon budgets, assumptions, costs strategy and tactics.
He is particularly interested in substantial cases where costs management has a material effect upon the commercial conduct of the underlying litigation.
Detailed assessment
Andrew has very substantial experience of detailed assessment proceedings, both between parties and between solicitors and their clients.
He regularly deals with preliminary issues capable of determining substantial parts of an assessment before individual items are considered, including questions concerning retainers, indemnity, contractual liability, the form and content of bills and points of dispute, and the recoverability of particular categories of expenditure.
Solicitor-client costs and retainers
Andrew acts for solicitors and former clients in disputes under the Solicitors Act 1974.
His work includes disputes concerning the existence, construction and enforceability of retainers; estimates and costs information; contentious and non-contentious business agreements; billing; special circumstances; success fees; deductions from damages; and the statutory machinery governing solicitor-client assessment.
He also advises solicitors upon the drafting and revision of retainers and funding documentation before disputes arise.
Commercial costs
Andrew deals with the costs consequences of substantial commercial litigation, including detailed assessment, consequential hearings, costs orders following applications and trials, Part 36 and other offers, security for costs and the strategic use of costs arguments during the course of litigation.
He has experience of costs disputes arising from litigation involving very substantial underlying commercial transactions.
Personal injury and clinical negligence costs
Andrew has longstanding experience of costs arising from personal injury and clinical negligence litigation.
He has particular expertise in Qualified One-Way Costs Shifting, having appeared in a series of Court of Appeal cases addressing points of principle concerning the operation and enforcement of the QOCS regime.
Andrew has a particular interest in the law and practice of litigation funding.
He advises solicitors, claimants, defendants, funders and insurers upon the legal and commercial arrangements through which litigation is financed and the costs consequences that follow from them.
His work includes:
Andrew's involvement in litigation funding extends back to the development of conditional fee litigation in the late 1990s and early 2000s. He appeared in Hollins v Russell [2003] EWCA Civ 718, one of the major early Court of Appeal authorities concerning conditional fee agreements.
He subsequently appeared in Essar Oilfields Services Ltd v Norscot Rig Management Pvt Ltd [2016] EWHC 2361 (Comm), concerning the recoverability in arbitration of the costs of third-party litigation funding.
Andrew accepts instructions in insurance coverage disputes, particularly where insurance overlaps with litigation funding, ATE insurance, legal expenses insurance or the conduct and financing of civil litigation.
His developing practice encompasses questions concerning:
He has particular expertise in the relationship between ATE insurance, litigation funding and costs, allowing coverage questions arising from funded litigation to be considered in their wider commercial and procedural context.
Andrew has extensive experience of credit hire litigation extending over many years and maintains a specialist website devoted to developments in credit hire law and practice.
He now concentrates principally upon complex, substantial and appellate credit hire work, including cases involving:
His reported credit hire cases include Gentry v Miller [2016] EWCA Civ 141, Tescher v Direct Accident Management Ltd [2025] EWCA Civ 733 and Motor Insurers' Bureau v Houston [2025] EWHC 3178 (KB).
In Tescher, Andrew appeared with Benjamin Williams KC for Direct Accident Management Ltd in the Court of Appeal in proceedings concerning when a credit hire organisation may be made liable for the costs of unsuccessful underlying litigation by way of a non-party costs order.
In Houston, Andrew successfully represented the respondent to a High Court appeal concerning credit hire, mitigation, impecuniosity, financial disclosure and the period of hire.
Andrew also accepts instructions concerning claims management companies and the businesses operating around civil claims.
This work sits at the intersection of his experience of credit hire, funding, costs, consumer contracts and insurance.
Areas of particular interest include:
Andrew does not approach claims management regulation as an isolated regulatory discipline. His particular expertise lies in disputes in which the regulatory framework interacts with the contractual, funding and costs arrangements through which claims are generated and pursued.
Andrew advises upon costs and funding issues arising from test cases, group litigation, representative proceedings and collective proceedings.
His experience includes Group Litigation Orders, collective proceedings and other forms of mass litigation, including questions concerning the allocation and recoverability of common and individual costs, litigation funding arrangements and the exposure of funders or other non-parties to adverse costs.
Andrew acts both for applicants and respondents in wasted costs and non-party costs applications.
He has advised and represented solicitors, liability insurers, ATE insurers, trade unions, litigation funders and credit hire companies in relation to potential liability for the costs of litigation.
Such applications can involve significant reputational as well as financial consequences. Andrew's approach is to identify at an early stage the legal basis upon which liability is said to arise, the evidential case required to establish or resist it and the relationship between the application and the conduct and funding of the underlying litigation.
Global Sports Data & Technology Group Ltd v IPS Law LLP [2025] EWHC 1910 (SCCO)
Andrew appeared unled for the claimant in substantial solicitor-client detailed assessment proceedings before the Senior Costs Judge.

Motor Insurers' Bureau v Houston [2025] EWHC 3178 (KB)
Andrew represented the successful respondent on appeal to the High Court.
The appeal concerned credit hire, mitigation, impecuniosity, the effect of an order relating to financial disclosure, the duration of hire and storage charges.
