Through one account, intermediaries will have access to multiple asset classes including exchange traded funds, exchange traded commodities and UK stock bonds.
The firm believes use of ETFs across platforms will grow significantly ahead of RDR.
Between April 2009 and April 2012, use of ETFs increased by 77 per cent and the value of ETF assets held by Barclays Stockbroker clients almost trebled, the firm said.
The service will be available 24 hours a day with the option to download statements and valuations and supported by a dedicated team with expertise in trading, account trading and transfers.
Will Burge, head of corporate sales at Barclays Stockbrokers, said: “More and more we are hearing about a growing demand from IFAs for access to a broad range of assets, and as we approach the arrival of RDR, we are seeing an increased demand from intermediaries for execution-only services.
“The relaunch of our service for intermediaries is in direct response to this feedback and is part of Barclays’ ongoing strategy to provide intermediaries with the products and services that will equip them to support their clients in the post-RDR world.”
