Excess Layer Insurance


building layersBusinesses sometimes need to insure for high levels of professional indemnity insurance (PI) cover. This could be because an important client demands it, or perhaps a particular project has a significant risk exposure.

When the level of cover required exceeds the capacity available from the primary PI insurer an excess layer policy, also known as 'top up' insurance, can be purchased. We can offer;

  • Cover up to £50 million
  • 'A' rated Insurers 
  • Dedicated PI insurance team
  • Policies tailored to the requirements of your firm
  • Free warranty and legal advice
  • Risk management insights delivered to your inbox
What is excess layer insurance?

All insurance companies have a maximum limit up to which they can offer insurance cover. The amount will vary between insurers but is normally up to £ 5 million for a primary professional indemnity policy.

Inevitably, many firms require more cover than their insurance company is able to provide. This is usually due to two reasons:

  1. An important client insists that the firm provides a specified amount of cover, giving them comfort they will not be under-insured if they ever needed to claim against them.
  2. The firm is involved in very large projects or areas of high risk where it feels that more PI cover is necessary to adequately protect the business.

This is where excess layer Insurance steps in. Additional 'layers' of cover which are purchased separately and sit on top of the underlying ‘primary’ policy.

For example, ABC Insurance Company provides the firm (the insured) with its main PI insurance policy for claims of up to £ 5 million. But the firm (the insured) has a large client who insists they carry PI insurance of £ 10 million. Their broker can then provide a separate excess layer policy with a different insurance company for an additional £ 5 million cover. The two policies combined are then providing the required £ 10 million cover.

This is common practice in the PI insurance market and enables firms to purchase almost any level of cover that they, or their client, requires.

building layersHow does it work?

The excess layer policy is only triggered if a major claim occurs which exceeds the amount of cover provided by the main PI policy. In practice, ABC Insurance Company will deal with all claims up to the first £ 5 million but if a claim occurs which exceeds the £ 5 million, then the insurance company covering the excess layer will pay the balance.

Some larger professional services firms such as solicitors and accountants may buy cover of £ 100 million or more. This could see at least 20 different insurance companies or more participating somewhere in the programme, depending on which layer they insure.

How much does it cost?

The cost of excess layer insurance is surprisingly modest compared to the primary PI insurance policy. In fact, it can be just a fraction of the cost of the primary policy.

This is because most claims will fall to the primary insurance policy and excess layer policies are rarely called on unless an exceptionally large claim occurs. This level of low risk is reflected in the cost of the excess layer insurance.

The cost or rate reduces as the level of cover increases so an upper level of excess layer will cost less than the lower level.  

risk calculator How is the premium is calculated?

Typically, an excess layer underwriter will first look at the usual risk information included on the proposer's PI proposal form together with the premium being charged for the primary insurance policy. They will then decide what they feel is an adequate premium for the level of excess layer they are being asked to provide.

This is done by using a combination of their own company ‘book rate’, some discussion with the broker and their own commercial judgement of the risk.
