If it were me, I wouldn't. Unless you have experience in negotiating money matters, and have the time available to take calls, arrange appointments, not be annoyed when people don't show up, etc etc. Estate agents have the office admin to do all that. Also they will have people on their lists who they can send details of the house to. Unless you have a very willing solicitor who can take on some of the nitty gritty sales process and the money negotiations.
An experienced estate agent will wring every bit of available money they can out of a would-be buyer. Also they can sort out the messers from the serious buyers who actually have the money.
What if you agree a sale and the seller says stuff like - oh can you take off 5k because our surveyor says it needs rewiring/the bathroom plumbing is going to the wrong pipe/chimney is unstable.
I'd run a mile from it if it were me, but that's just from having sold and bought myself a couple of times - using estate agents.
As a buyer I'd be very very wary of someone selling a house themselves. I'd figure if they were that keen to save the few thousand on the estate agents fee, that there would be no way they would give me a bargain on the house. If it was that easy we'd all be doing it.
