BlackRock Smaller Companies Trust
A London-listed investment trust focused on long-term investment in smaller UK companies.
Last updated August 25, 2026
Overview
BlackRock Smaller Companies Trust is a British investment trust listed on the London Stock Exchange under the ticker BRSC. Its mandate is centered on investing in the equity of smaller companies, principally in the United Kingdom, with the objective of generating long-term capital growth for shareholders. Rather than offering a conventional retail fund range or a consumer-facing financial product, the trust is a single listed investment vehicle whose shares trade on the public market and whose portfolio is managed under an external investment-management mandate. The trust traces its origins to the North British Canadian Investment Company, established in 1906. Its identity and investment-management arrangements changed several times as the vehicle evolved. In December 1993 it was renamed NB Smaller Companies Trust, and in December 1995 it became the 3i Smaller Companies Trust. Merrill Lynch & Co. subsequently secured the investment-management mandate, leading to the name Merrill Lynch British Smaller Companies Trust in February 2005. Following the merger of Merrill Lynch Investment Management with BlackRock in February 2006, the trust ultimately adopted its current BlackRock name in April 2008. The trust's investment proposition is exposure to the smaller-company segment of the UK equity market. Smaller companies can offer access to businesses with expansion potential, specialist positions, or comparatively early-stage growth characteristics, although they may also be more volatile and less liquid than larger listed companies. The vehicle therefore represents a specialist allocation rather than a broad-market equity substitute. Investors buy and sell the trust's shares on the London market, while the portfolio manager selects and monitors underlying holdings. BlackRock Smaller Companies Trust is associated with BlackRock, the global investment-management group that inherited the relevant management platform after its combination with Merrill Lynch Investment Management. The trust is a constituent of the FTSE 250 Index, reflecting its status as a sizeable listed UK investment company. Its board and investment manager have distinct roles: the board oversees the investment company and its governance, while the appointed manager is responsible for implementing the portfolio strategy. In February 2026, BlackRock announced a proposed combination involving BlackRock Throgmorton Trust. The stated structure involved transferring the assets of BlackRock Throgmorton Trust to BlackRock Smaller Companies Trust and subsequently winding up BlackRock Throgmorton Trust. This represents a strategic consolidation within BlackRock's listed investment-trust range and may affect the scale and composition of the continuing vehicle, although the reference material does not provide transaction terms or completion details.
History
BlackRock Smaller Companies Trust originated in 1906 as the North British Canadian Investment Company. The original vehicle was established well before its present BlackRock identity and subsequently changed its name and investment-management relationships as the UK investment-company sector developed. In December 1993, the company became NB Smaller Companies Trust. The change placed the smaller-company mandate more prominently in the vehicle's public identity. Two years later, in December 1995, it was renamed the 3i Smaller Companies Trust, reflecting a further stage in its corporate and management history. Merrill Lynch & Co. later obtained the investment-management mandate. In February 2005, the trust adopted the name Merrill Lynch British Smaller Companies Trust. This name emphasized both its UK geographical focus and the involvement of Merrill Lynch as investment manager. The trust remained a listed investment company focused on smaller-company investments rather than becoming a conventional open-ended fund. A further transition followed the February 2006 merger of Merrill Lynch Investment Management with BlackRock. As the investment-management platform became part of BlackRock, the trust was eventually rebranded BlackRock Smaller Companies Trust in April 2008. The current name links the vehicle to BlackRock while retaining its defining smaller-company investment focus. The trust is listed on the London Stock Exchange and trades under the ticker BRSC.L. It is also a constituent of the FTSE 250 Index. Its structure gives shareholders access to a managed portfolio through shares in a listed investment company. The investment objective is long-term capital growth, primarily through holdings in smaller UK companies, a segment that can provide growth opportunities but can also involve higher volatility and lower liquidity than large-cap equities. Governance is conducted through the trust's board, with investment management performed under the relevant BlackRock mandate. Ronald Gould is identified as chairman in the available reference material. The available sources do not provide a complete historical list of directors, portfolio managers, launch terms, or detailed performance data. In February 2026, BlackRock announced a proposed combination with BlackRock Throgmorton Trust. The proposed mechanism was the transfer of Throgmorton Trust's assets to BlackRock Smaller Companies Trust, followed by the winding up of BlackRock Throgmorton Trust. The announcement indicates a consolidation of related listed investment vehicles, but the available material does not state the final completion date, shareholder terms, post-transaction portfolio size, or other financial details.
