However, a second Act of Parliament, obtained in 1807, authorised them to raise another £60,000, which was used to extend the canal to Memel Wharf and a basin at Camberwell. This work was completed in 1810. So far, the route had been level, but to go any further would have needed locks or inclined planes, and the expected costs of their construction did not inspire the company to proceed with them. A short branch of about was constructed in 1826, running from Glengall Wharf to Peckham Basin. Two further acts of parliament were obtained in 1808 and 1811 to allow new funds to be committed to the project.
