Russell-Cooke solicitors Southampton office.

About Peter

I am a lawyer that understands numbers and accounts – I like accounts, and accounting principles – and that gets me to the core of a deal. I have many years of experience helping clients build their business, raise finance, buy business, and sell them.

Peter’s client base is primarily within the tech sector; however he has significant experience in joint ventures and LLPs as well as in some general transactional corporate work.

Typically, his tech sector clients are serial entrepreneurs, who acquire, develop, raise finance, issue EMI shares, and enter into shareholders agreements as well as sell and reinvest. Often they have a secondary management team, who often go on and become serial entrepreneurs. Peter brings over 20 years of specialised experience to deals undertaken in the tech sector.  

The vast majority of clients that Peter works for have engaged in repeat business with some relationships spanning ten, 20 and even 20 plus years. Peter excels in client relationships, as clients recognise that he is unequivocally on their side and will do the upmost to achieve his clients’ desired outcomes.

An additional area of expertise is restructuring and insolvency. During the early 1990s, Peter dedicated several years to this field, and in 2010, his invaluable experience in handling financial challenges proved beneficial as many of his clients faced difficulties.

Peter Jeffery is a well-regarded corporate lawyer at Russell-Cooke with a focus on transactions in the technology sector. He has a strong track record of acting on M&A and restructuring matters.
Chambers UK (2024)


Peter has run at least of 50 deals within the tech sector. A significant 70% of his clients have maintained a working relationship with him for over a decade. While the majority of Peter's work involves transactions, typically falling within the £5m-£25m range, he has also handled many deals in the £30m-£60m bracket, with some exceeding this.

Peter joined Russell-Cooke in 2023 having been a partner at Moore Barlow since 1998. After its merger in 2020, Peter led the business division (corporate, employment and commercial) for the latter three years of his tenure. Prior to this, Peter was a partner at Pitmans.
