Well F&T on high street sells climbing gear, but it is closing down in about 4 weeks time, if there is something particular you want they might have it and you could get 20% off.
There is Cotswolds, that is in Hedge End. Otherwise your choice is Snow and Rock at Port Solent (just Soton side of Portsmouth) or Peglers in Arundel - probably the best if your prepared to do 70mile round trip.
