The fact that you have been looking for 6 years and presumably in the right places speaks for itself and tends to prove that, as pointed out already, that there are no full WW2 service records on line.
Ancestry for example does have some WW2 records such as the UK Roll of Honour which shows name and number of some WW2 casualties (but then so does the Commonwealth War Graves Commission site) and POWs. Findmypast also has some records such as RAF combat reports and some casualty lists. Other similar sites also have random WW2 related info but none have full service records.
Why not if WW1 records are available (if they survived) on some sites? Because, when the relevant regulations allowed, the service personnel authorities first handed over the records to the National Archives and the National Archives entered a commercial arrangement with Ancestry etc.
That process has not happened with WW2 records. However, it may be of interest to know that there is a plan to do the first part of that process, ie military to National Archives, in the coming months/years. How the National Archives will make them available will be up to them. The task will be a mammoth one and will no doubt add time to the already long time frame to obtain records which has been much exacerbated by covid such that waits of over a year now are not uncommon.
