Yes forget the mapping... what you can do is load up the fab contour data created for the Scottish Mountaineering Club http://www.smc.org.uk/ContourMaps.php I do use that... and its free!
Agree with Manu... THe accuracy is at best 3m however 5m will be a good day... and that means that your point is within a 10m circle so fine survey it ain't. On the other hand, you next step is this... http://www.fondriest.com/products/ashtech_990586-01.htm MobileMapper CX rugged handheld GPS receiver with sub meter accuacy.. though this is going to cost about 1800 quid.
and then of course, if it really matters, you can hire this beuaty... http://www.leica-geosystems.com/en/GNSSG...0_4521.htm but you need special training and software. MMMMMMmmmm the Leica 1200 RTK GPS which I was using to accuracy of +/- 2-3mm that said it will set you back 20k

But you can hire for only about 3-400 quid a week
