not extending - how bad is that in eyes of an agent

[psychocandy]

You won't lose him.

No matter how badly you treat agents, they're soon back like whipped curs, offering you new roles

You could "spit roast" their mother and they'd still be back on the phone the next day if they could make a few £ out of you.

It's just for discussion. I know what to do.

I'd be more concerned about upsetting my cat than upsetting an agent.....

OP it is very much a case of telling the agent straight. and don't burn any bridges with your client.
That way for him it should be win win, he can square it up with the client or even get WFH for you if you want it instead.

If not, then he gets to place a newbie on site assuming they truly intended to extend you.
Plus simply because you weren't walked he now sees you as a cash cow.
So unless he is a twat he will try and place you nearer home to keep you happy and the kerching coming in, there really is no incentive for him not to try.

MTFU.

Tell him the truth, give plenty of notice, parachute a sub in if you can.

HTH.
