Something like this (I know it's aus, not the UK, but it seems, er, sensible? good airmanship, something like that?)

Avoiding Controlled Airspace
The pilot in command of an aircraft operating in Class G airspace,
or to the VFR in Class E airspace, must apply appropriate toler‐
ances to the flight path to ensure that controlled airspace, or re‐
stricted areas, are not infringed.
In calculating whether an intended flight path may infringe con‐
trolled airspace, the following navigational tolerances must be ap‐
plied to the intended flight path depending on method of navigation
used. These tolerances may be rounded up to the nearest half de‐
gree for practical purposes:
NDB ±6.9°
VOR/TACAN ±5.2°
DR ±12°
Note: For DR tracking ±9 o
may be used where initial track
guidance has been provided by NDB, VOR or TACAN and there is
no subsequent change in track.
VISUAL (POWERED AIRCRAFT)
0 - 2,000 AGL ±1NM ( ±2NM by night)
2,001 - 5,000 AGL ±2NM ( ±3NM by night)
5,001 - 10,000 AGL ±4NM ( ±5NM by night)
