NS&I says the milestone means that almost 1 in 5 UK advice firms have signed up. 

NS&I is planning further enhancements to adviser service this year, including looking at ways of expanding the information available. 

It plans to make changes later this year with the digitisation of Letter of Authority processes as well as a new and updated version of its Adviser Centre. 

NS&I also has plans to simplify other processes for advice firms, creating a "full service digital offering" for advice firms. 

Andrew Pike, head of intermediary relationships at NS&I, said: “I am thrilled that more than 1,000 advice firms are now using NS&I’s online service and to hear about how much easier it has made their interactions with NS&I. 

“Financial advisers, planners and Paraplanners are extremely important to NS&I and we’re proud that almost 1 in 5 firms across the UK are now using our online service. Our online service is free to use and easy to register for.

“We have 25 million customers across the UK, so it’s our assumption that most advisers will have clients with NS&I holdings. We encourage all advice firms who have not yet registered for our dedicated online adviser service to sign up.”

The online service was launched in May 2019 following feedback from advice firms. 

The service allows advisers to access details of clients’ NS&I holdings including: 

• Viewing a list of their clients' NS&I holdings (subject to a Letter of Authority)
• Selecting a client and viewing their NS&I portfolio
• Viewing the transaction history of an account
• Get a valuation of fixed term accounts and seeing maturity dates
• Viewing copies of communications sent to clients from NS&I
• Viewing a client’s Premium Bonds prize history

The NS&I team will also be going back on the road at industry events in 2022.
