ESPL Regulatory Consulting

Innovation. Experience. Dependability.


About Us

Embedded Signal Processing Ltd (ESPL) was originally established in 1996 as an electronics development and consultancy company. In 2000 the business branched out and ESPL Regulatory Consulting was founded, led by Helen Erwood a former senior Regulatory Affairs Professional at SmithKline Beecham (now GlaxoSmithKline). In April of 2019 the company became employee owned under the leadership of Jason Collins and Chris Erwood with Helen continuing in a consultancy role.

ESPL has its main offices at Lunna House in the beautiful north-eastern corner of the mainland island of Shetland, with a second office in Glasgow and an array of remote staff across the UK and Europe. the company is today both a Shetland-based enterprise and a “virtual” business with staff and expert consultants based across Europe, North America and Australia.

ESPL values the integrity, professionalism and commitment of every member of its team; we believe that working to live, rather than living to work, is an important principle, and having a team with a healthy work-life balance and an enthusiasm for the task ahead means that the quality of support given to our clients is consistently high.

  • Team members are task orientated: we don't have fixed office hours and work in complete tandem with family life.

  • Our collaborative approach to managing the business means that we all care about supporting your regulatory needs.

  • The team has a wealth of regulatory experience which means that we can engage with organisations and regulatory agencies at all levels.


The ESPL Team

Each member of the ESPL team brings enthusiasm for and specific experience in a wide range of aspects of regulatory affairs, so that we can provide just the right level of expertise and support our clients' need. Most of our team has a minium of ten years Regulatory Affairs experience in the pharmaceutical or devices industry (many have much more than this). Clients with complex submissions are supported by a multidisciplinary team, including an electronic publishing team, chosen to provide optimal support at each phase of any regulatory procedure.
