Below is a direct quote from HSG 17 regarding 110v grinders:
123 All tools should be accompanied by specific instructions from the manufacturer. If there are no instructions, the following system of planned maintenance is recommended. All hand-held apparatus, including extension leads, should be identified by a serial number which should be recorded in a register. The register should indicate how often each item should be recalled for inspection. The recommended frequency of checks, inspection and testing for portable electric grinders is:
(a) For 110-volt machines the user is to carry out:
(i) a weekly safety check;
(ii) a formal visual inspection (eg a detailed inspection by a person competent to do so);
(iii) a combined inspection and test every three months (eg a detailed inspection and tests by a person competent to do so).

We normally get the site store man to visually inspect the leads/ casing and if it is running properly on a weekly basis, and he records this every week, but that is because it is on a construction site
What I would like to know (as myself and numerous other safety bods are unclear), is at what point do the inspections have to be recorded? At present we are complying with the PAT requirements of a 3 monthly recorded inspection. However, if the first 2 are not recorded what proof do we need/is required that they were carried out?
