Independent consultant vs firm-employed: how the working structure affects PI cover

A management consultant in the UK can operate under one of three broad working structures: as an independent consultant working through a personal service company or umbrella, as an employee of a management consultancy firm, or as an associate on contract to one or more consultancies. Each structure carries a different professional indemnity insurance position, and consultants moving between structures — as is common in the profession — need to understand how their PI cover follows them. This entry sets out the three structures, how PI attaches under each, and the transitions between them.

Independent consultant working through a PSC

An independent management consultant typically operates through a personal service company — a limited company through which the consultant contracts with clients. The PSC is the contracting party; the consultant is the sole director and shareholder. From a PI perspective, PI cover is typically placed at PSC level and covers the professional services delivered by the PSC (which in practice means the consultant's work).

Typical limits for independent consultants working with SME and mid-market clients: £500,000 to £2 million each and every claim. Higher for consultants working with enterprise clients (£5 million upwards) or public sector clients (often specified at £5-10 million as a tender requirement). The PSC's insurance is a critical factor at proposal stage for many client engagements; a PSC without PI often cannot secure engagement at all.

The independent consultant's PI attaches to the PSC's engagements and does not typically follow the consultant to work performed as an employee of another firm. A consultant who takes a role as an employee of a consultancy while maintaining their PSC needs to be clear about which activities are done through which entity.

Firm-employed consultant

A management consultant employed by a consultancy firm is covered by the firm's PI cover for activities performed as an employee. The firm holds a policy at firm level, sized to the firm's aggregate exposure. The individual employee does not need to hold personal PI cover — the firm's policy responds to claims arising from the individual's work within the scope of employment.

The specific coverage terms depend on the firm's policy. Most firm-level policies expressly cover activities of employees within the scope of their employment, including work delivered on client engagements. Some policies exclude activities outside employment — moonlighting, personal advisory work performed on the side. Employees who undertake side consulting activities should confirm whether the firm's policy covers them or whether separate personal cover is needed.

Associate on contract

The associate model — where a consultant contracts with a consultancy firm to deliver work on the firm's client engagements without being an employee — is common in the UK management consultancy market. Associates typically operate through their own PSC and are engaged by the primary consultancy under a sub-contractor agreement.

The PI position under this structure is more complex. Three questions matter:

First, does the primary consultancy's PI cover work delivered by associates? Some firm-level policies expressly cover associates; others limit cover to employees only. This should be checked at proposal stage.

Second, does the associate's own PSC PI cover work delivered under the primary consultancy's engagement? Some PSC policies cover the associate's activities regardless of who they are engaged through; others have specific provisions for sub-contracted work.

Third, how do the two policies coordinate if a claim arises? Where both policies could respond, the associate agreement should specify which is primary and which is excess. Where only one policy responds, the other party may be uninsured for the affected work.

The moonlighting problem

A common transition scenario is a firm-employed consultant who begins taking on freelance or associate work on the side. The PI position becomes ambiguous:

The firm's policy likely covers work done within the scope of employment but not work done through a separate PSC arrangement, even if the two blur in practice.

A newly-set-up PSC without its own PI policy leaves the moonlighting work uninsured.

Where the moonlighting work is done for the firm's clients directly, the firm may argue it is within employment; the client may argue it was done through the individual's own capacity; the resulting claim can trigger disputes about which cover responds.

Consultants beginning to take on side work should set up appropriate PI cover for the side activity from the outset, and should be explicit with the firm about the arrangement.

Career transitions

Consultants moving between structures — from employee to independent, from independent to employee, from associate to employed — need to think about run-off cover for work done under the previous structure. Where a consultant leaves an employer's protection, any residual liability for work done as an employee remains with the former employer's policy (typically covered by continuous cover provisions in a firm-level policy). Where the consultant is winding up a PSC, run-off cover on the PSC's PI policy is needed to cover claims that may surface after the PSC ceases trading.

The typical run-off period for management consultant PI is six years, matching the general Limitation Act 1980 window. For work with longer-tail exposure — particularly financial services advisory or regulatory work where the client's own regulatory framework can generate claims years after the advice — longer run-off may be appropriate.

Recommended cover levels

Broad ranges for the three structures, calibrated to typical engagement values:

Independent PSC consultants working with SME/mid-market: £500,000 to £2 million.

Independent PSC consultants working with enterprise or public sector: £5 million to £10 million.

Firm-employed consultants at Tier-1 firms: individual cover not required; firm-level cover typically £25 million or higher.

Associate consultants working with mid-market consultancies: £1 million to £5 million on the associate's own policy, with the primary consultancy's policy providing additional or coordinated cover.

Worked example

Illustrative only. A consultant leaving a Tier-2 consultancy after eight years to set up as an independent. During employment, all consultancy work was covered by the firm's £15 million PI policy; residual liability for those engagements remains with the firm's policy under standard continuous cover provisions. Post-departure, the consultant sets up a PSC and places a £2 million PI policy for the new independent practice. First independent engagements are with mid-market clients where £2 million is comfortably above the largest realistic loss. As engagements move upmarket over the following two years, the consultant reviews and increases the PSC cover to £5 million. Change reviewed and confirmed with broker at each stage.
