I would try! I did online dating a couple years ago and got a couple dates. Things didn't work out and had some issues with rejection after but would definitely try again maybe in the future. My preferred method would be meeting someone at work or organically but sometimes you have to take some risks. I used Match.com as I live in the United States and also a Christian dating website called ChristianMingle as I was looking for a woman in the Christian faith. I'm not sure if they maybe have Match in the UK or what the best dating website would be. My sister met her husband through online dating. You could always try a couple sites and see what you like best. I also really like BTDT's advice above about meeting someone through charity or volunteer work.
