It depends on what has been done on the computer since the data loss, how
it happened and hard ware issues involved.
Generally, if its simply getting data from the hard disk (because the operating
system will not run) then cost will be : ~£39.
If its more serious than that (eg: damaged hard disk) - the cost could be
anything from £100-500 depending on steps taken - quoted cost here may
rise steeply depending on damage.
No guarantees can be given due to the nature of the severity of damaged hardware.
We can also charge, if you prefer, at an hourly rate - depending on how long
it takes us to find/recover the data the price will obviously vary (at the
rate of £40 / hour or part thereof).
