The company said the platform was the first step on its journey towards offering an end-to-end solution to advisers.

The firm is still awaiting FCA approval for the launch of the platform.

When it launches, the new platform will allow instant deposits and an auto-investment function to allow investments to get to market faster.

It will offer a multi-model approach so advisers can hold various investment strategies in one wrapper. There will be no minimum cash balance required and there will be tiered adviser charging with flexibility on fees.

The company said it chose Seccl for its speed to market and ease of connectivity. Seccl is an embedded investment platform owned by Octopus.

Nick Raine, chief executive of Söderberg & Partners’ UK business, said: “We want to reduce the administrative burden on advice firms so they can concentrate on helping their clients and save money.

“We are looking to our Nordic roots for inspiration, and to learn lessons about how we can improve adviser-to-administrator ratios to make advice more efficient. Our overall aim is to reduce the cost of advice and support advisers to deliver better service to end clients.”

He said that other partners were set to be announced in the coming months.

David Ferguson, chief executive of Seccl, said: “We have a clear ambition to bring change to the industry by doing things better. With our hyper-efficient infrastructure, Seccl’s embedded investment platform is perfectly placed to deliver this, helping advisers grow their businesses and deliver better outcomes for their customers.”

Söderberg & Partners was founded in Sweden 2004 and is today one of the largest providers of wealth management and corporate insurance services in the Nordic region and the Netherlands.

The company has more than 3,000 employees working from more than 110 offices in Sweden, Norway, Denmark, Finland, the Netherlands, Luxembourg and Spain, and more than £60bn in AUM and AUA.

In September it acquired a majority stake in London IFA Timothy James & Partners and minority stakes in two other UK advisers - Dartington Wealth Management and Atherton York - as part of its expansion drive in the UK.

It entered the UK adviser market earlier this year when it said it aims to partner with up to 1,000 financial advisers in the UK within five years.
