In addition to waimarie's answer, we had the right raw materials, especially coal and metal mines. Iron began to be smelted using coke, giving a higher temperature. Any raw materials we did not have could be brought from the colonies. We had the strongest navy which spent part of the time protecting trade routes and the rest keeping the French navy blockaded in port. We also had a strong army which ensured that we would remain in control of the empire. Farming had become mechanised and the labour was drifting into the towns where industry was starting up. It has to be said that much of the investment came from money made in the slave trade. Like Waimarie, I think this should be a longer answer, but is what I can think of on the spot. There must be a lot on Google. As well as Industrial Revolution it would be worth searching on Coalbrookdale and Abraham Darby.
