Rachel Quickenden

Rachel is an experienced lawyer, specialising in complex white collar crime, general crime and regulatory matters. She advises and defends individuals and corporations who are subject to investigation or prosecution and has extensive experience of dealing with the police, Crown Prosecution Service (CPS), Serious Fraud Office (SFO), US Department of Justice (DOJ) and a variety of regulators. 

Rachel is adept in advising clients accused of conspiracy to defraud, conspiracy to cheat the Revenue, theft and money laundering, and many of her cases have an international element. She has years of experience acting for clients who are the subject of restraint orders and confiscation orders to the value of tens of millions. 


Rachel has extensive experience acting for clients at interview stage, including interviews with the police, SFO, DOJ, regulators and employers as part of internal investigations. She is strategic from the outset, having regard to both the short-term and long-term implications of investigation, and strives to obtain the best possible result for her clients as early as possible. Rachel is also experienced in advising witnesses who are the subject of section 2 interviews and compulsorily required to attend for interview. 


Rachel has worked on regulatory matters involving the Financial Conduct Authority (FCA) and the Air Accidents Investigation Bureau (AAIB). Many of her clients have faced multi-faceted investigations, sometimes spanning internal employment matters, regulatory and criminal investigations. Where appropriate, she works collaboratively alongside other lawyers and experts to ensure that her clients receive the best advice, from every perspective. 

Having qualified as a police station representative early on in her career, Rachel has acted for clients facing a vast range of allegations; from assault to theft, drugs offences to sexual offences. She understands both the emotional impact and the potential for collateral damage as a result of such an allegation, and thus gives consideration to wider implications facing such individuals and/or corporations. 


Rachel is praised for her calm, personable manner and for providing exceptional client care. 


Rachel has acted in a number of high-profile cases, and her recent cases include:


  • Defending in the prosecution of Barclays Bank and a number of its executives. The case against her client was dismissed. 

  • Acting for an individual who was prosecuted as part of Operation Amazon, a case brought by HMRC (then the CPS) in relation to a carbon credit scheme with alleged intended losses of around £110m. 

  • Defending an individual prosecuted as part of a conspiracy in a carbon credit MTIC fraud, to the value of £39m. 

  • Advising a number of traders throughout investigations by banking institutions and authorities, as part of the foreign exchange and EURIBOR investigations
