Lloyds TSB Insurance is to begin a pilot scheme to sell commercial insurance to its larger business customers.
The move, an expansion of its present commercial insurance operations, would target business clients with turnover of between £2m and £25m.
At present, the bank targets smaller business clients with turnover under £2m.
"We want to increase the range of customers we quote for," Phil Loney, managing director, Lloyds TSB Insurance, told Insurance Times.
The announcement came as the company reported half-year pre-tax profits of £114m, up 21% on the previous year.
New home insurance gross written premiums through Lloyds TSB's UK Retail Bank grew by 39%, with sales via the internet now accounting for 34% of all direct sales volume. New gross written premiums from commercial insurance increased by 12%.
