I am looking for a good reliable Suzuki dealer in London and surrounding area, can anyone help.
Not strictly London but only one I can recommend is Ford and Ellis of Chesham if its new your after.
For servicing I won’t use anyone but Road and Track Dyno/MSG Racing.
West London Suzuki seems a good dealership, but I’ve no personal experience with them.
Lloyd Coopers in Watford. My neighbour has gotten his last bike from there and he is really happy with the service and servicing.
http://www.johnsofromford.co.uk/ has a suzuki store
+1 i was quiet happy with them when i had my servicing done. 
I have. I wouldn’t let them loose with a pushbike, nevermind a motorbike!
I’ve used Ford and Ellis and they’ve always been pretty good.
Aye Gees in welling is back up and running and seemed like a friendly bunch when i was in there a while ago.
Or E C Bates http://www.ecbate.co.uk/ in dartford is good.
Premier Motorcycles in West Wickham have always been really good to me…
never used it myself but im always happy with the honda store/servicing etc
+1 on both counts
+1 bought my bike form them and have it serviced there - very friendly and helpful. Gave me a great deal on the purchase and always loan me a bike when mine’s in for a service
Southern Cross are now a Suzuki dealer should be good. 
Sarff of the river there is Aye Gees at Welling and Bates’ at Dartford.
Used Bates last year for a service on my old bike and they were fine. My more recent experiences have been at Aye Gee. I bought a new Bandit there last July. I know there are mixed views about them but I have always found them to be friendly and helpful. A guy called Darren is in charge of servicing and he knows his stuff.
George Whites Suzuki in Slough are ok.
Yes try Southern Cross as someone mentioned before. I just bought a bike from there and had it serviced. Also Geomoto in Finchley were pretty good.
There’s a George Whites in Shoreditch too.
not a bad lot at all, i bought my SV1000S from them, nice fellas and helpfull, fixed a fault with the bike without anyqualms and even loaned me a bike whiel mine was sorted.
