Further to the last post
Deconfliction from CAP774 (Nov 2009) is
'surveillance-derived traffic information and issues headings and/or levels imed at achieving planned deconfliction minima'
Those minima are
5 NM laterally or 3,000 ft vertically and, unless the SSR code indicates that the Mode C data has been verified, don't allow the targets to merge.
or if coordinated
3 NM laterally or 1,000 ft (there are limited conditions where 500 feet is allowed)
Unless you have two turbines pushing you, think very hard about asking for a deconfliction service - you need an awful lot of sky to achieve the required separation.
