It was previously only accessible to individuals and trusts.

HSBC said it opened up the funds due to an increasing number of enquiries from advisers working with UK companies.

Mark Lambert, head of onshore bond distribution, HSBC Life (UK) Limited, said he expected to see the potential to optimise tax planning through an onshore bond generate significant interest among advisers’ corporate clients.

He said: “Advisers have made it clear to us that there is an increasing demand from clients for onshore investment bonds, and we have significant growth ambitions in the onshore investment bond market. Our priority is to offer advisers and their clients - including companies - investment choice, transparency and value supported by the highest levels of service.”

The HSBC Onshore Investment Bond offers an open architecture approach providing advisers with the opportunity to choose from over 3,800 investment funds.

HSBC does not replicate the funds offered by external fund managers, instead it enables investment in the funds directly for a consistent approach.

To invest in the HSBC Life Onshore Investment Bond companies must be UK tax residents. The minimum investment by a limited company is £15,000.

Each company can hold up to a maximum of 1,200 policies with the Bond, with each policy holding a minimum of £1,000.

HSBC Life (UK) is the insurance business of the HSBC Group. It offers insurance services to meet protection and investment management needs. Its services and solutions are available through HSBC banking channels, financial advisers and aggregators.
