Berwin Leighton Paisner (BLP) is launching a key client programme as part of a drive to boost revenues from major client relationships.

The UK top 20 law firm intends to focus on around 30 relationships across all practice groups, with names expected to be finalised by the spring.

Clients will be assessed on a number of factors including billings, with only those billing at least seven figures annually expected to feature. Other considerations will include the history and strength of the relationship, likelihood of future instructions and how the client fits in with the strategic direction of the firm.

High-profile clients such as Tesco, Thames Water and Royal Bank of Scotland (RBS) are likely to be included on the roster. As part of the plans, the firm has appointed a 10-member steering committee to identify the clients.

The group, which consists of lawyers from all of the firm's practice groups as well as business development professionals, is being led by finance head Matthew Kellett. Kellett (pictured), a former partner at Linklaters, joined BLP last year from RBS, where he was head of the financial structuring group.

He said: "This exercise will help us identify where to put our resources going forward. It is good business sense. It will help us focus our efforts, not least when deciding what proportion of the marketing budget we should spend on each client.

"It will also help internal communication, as sometimes it is not clear to all practice areas just how important a client is to another group within the firm."
