Difficult to say but probably worth £150 - 200 if the parts are okay and frame is totally clean and undamaged. Some folk would pay more 'cos its a Condor, but it looks like a basic functional ally framed job to me.
To go back to geared you would need derailleurs, shifters/brake levers/bars, cassette, possibly new rear wheel.
Edit - just noticed the brakes. It's a cyclocross bike. Flee!
