I recently arrived in London and I'm currently searching for the best fish and chips in town...
If you can make the trip up, I highly recommend Toffs of Muswell Hill (http://www.toffsfish.co.uk - nearest tube Highgate). It's probably the best fish and chips I've tasted in London. You can eat in, or get it to take away.
Fishers in Fulham is definitely worth a visit.
It's a family owned small restaurant where you can eat in or take away.
Reasonable prices and really nice staff.
Hook in Camden is great. Poppies is incredible. I'm also a huge fan of Sutton and Sons.
I prefer Fryer's Delight near Holborn, Chris's in Chiswick and Fish Bar in Bermondsey.
