11 year old wimpey house you've almost certainly got 6 inch joists.
you could try shimming the wall, not too difficult, lift the floor covering to expose the sub floor. have a look at where the wall meets the floor. is there a gap? you might need someone to walk around on the floor to see if any movement.
often there will be a gap visible even under the skirting. get some plastic shims in various thicknesses (most builders merchants will stock them) and pack out the gap between the floor and the base of the wall - under the stud and nice n' tight. better still use metal shims if you can get them.
have a couple of people stood either side of the wall as you do it - otherwise the shims will simply come loose and slide about.
like i say it's not a perfect fix, but it's something that can be done in minutes with minimal mess. in other words it's quick, cheap and worth at try. hopefully it will at least reduce the squeaking. i did this for a customer who has a 2-year-old who barely slept. driving the poor lady mad as she'd wake her baby every time she went into the bedroom the squeaking was that bad. i was able to reduce but not eliminate the problem with this method.
other options are to stiffen the floor joists with steel braces. this would be quite a job however. you'd need to pull up the sub floor (probably large boards rather than the more traditional 180mm wide floorboards so a bit of a faff) or get access through the ceiling below.
or pull the wall down and reinstall. but none are guaranteed fixes i'm afraid.
