Seasoned Professionals

Our Philosophy

Leaman Crellin Limited provides a helping hand to individuals in regulated firms who don't have the bandwidth to get to everything.

Our shop gives you confidence that you have covered the right topics and saves you time reading around, or, downloading a free generic document in the hope it has some relevance but doesn't say what you can do, or worse having to spend large sums hiring a third party to come onsite for weeks on end.

Our clients have discovered the convenience of being able to immediately address a wide range of common issues through our digital downloads knowing the products are written by seasoned professionals with a focus on being practical, easy to follow, and implement.

Resources are finite


Whilst the financial services sector benefits from a deep pool of regulatory compliance personnel, resources and time are finite. Many firms are finding they need to be across a broad number of regulations and sometimes to a technical depth that requires time to learn and keep up to date.


When a new requirement comes out or a new risk or issues is identified, often there aren't enough hours in the day to do the research, identify the salient points and put that in a way that is immediately relevant for their firm. This isn't a competency issue it's purely capacity. Our digital downloads are available to download 24/7 and give you the capacity you need whenever you need it.

Span of Regulations

Financial Services regulations span a diverse and broad range of products and services some of which are very technical. By their nature the regulations can also become technical. They can also be presented in a negative way: this is what you cannot do.

We prefer to say up front what is just not possible and quickly focus on what is possible and how to achieve that.

These range from practical challenges such as how to evidence compliance with all applicable rules at all times, through to establishing global standards for protecting clients assets, to getting a successful outcome from a section 166, skilled person review. Through to regulatory issues such as the Professional Indemnity Insurance crisis of 2002/03, to raising standards of professionalism in the retail distribution sector, and how to proactively engage regulated firms with limited resources through roadshows and one to one's.
