mike green,
If you are referring to an outside gulley you will have to get a hand down into it to clear the invert and outpipe.

mike green,
Did you manage to get your hand "round the bend" and clear the outlet pipe, this has to be your priority before going further.

A set of drain rods is the best bet for tackling this problem. These can be purchased relatively cheaply from DIY stores, or hired from a Tool Hire shop, and will certainly be cheaper than calling in Dynorod.

While the rods are too rigid to bend around the u-bend, using the 4" flat rubber end piece you can force water through the pipe with some force. This may well dislodge a build up of fat, hair and tissues etc.

If this does not shift it, then tackle the problem from the other end, the sewer manhole. Use the rods to push the blockage the other way, towards the u-bend and gulley.
