I understand all of that and do not have any argument against your findings.
I apologies for the length of this! I need not tell you that brevity of writing is not one of my conspicuous virtues
t's not so much 'findings' as 'the way it has been (dictated by clients) for decades and, perhaps more important, the way in which all those with whom I have been 'competing for work' have done things. I have, however, somewhat over-simplified how things work for me (see below).
Equally I do not any issue with going to the effort you do on a regular basis rather than evening it out.
As above, it has not really been 'by choice', even though it has seemed pretty reasonable ('very fair') to me.
Whether or not 'evening out' is a practical and reasonable way of doing things probably depends a lot upon the nature and extent of the work, and the extent to which overheads are fairly consistent across jobs..
As above, I have oversimplified 'my world'. As with any self-employed person (or company running a business), my 'charge out rate' takes into account all the standard, fairly predictable, annual overheads, translated into a 'per hour' figure on the basis of an estimated number of hours work per year - which is why those 'charge out rates' are so much higher than the hourly pay rates that an employee would expect for doing the same work. Those 'built-in overheads include (for a person like me) such things as insurance, provision for holidays and sickness, part of NIC, heating/lighting of 'home office', (part) provision/maintenance of a vehicle, telephone costs, cost of maintaining/replacing IT etc. equipment, 'office supplies' etc. etc.
and a provision for 'reasonable amounts' of travel (including 'travel time')
Whilst ('over-simplifying') I have said that I explicitly re-claim the cost of 'expenses' from a client, that only relates to expenses beyond those which are already built into my 'hourly charge'. This is usually reflected in the contracts, which generally specify rates of reimbursement for mileage beyond some specified figure (commonly 25-50 miles per day) and also payment for 'travelling time' beyond some specified figure (commonly about 2 hours per day) - so, in reality, I do not have to claim extra for 'travel' all that often - since most of my 'overheads' are covered by the figures 'averaged-in' to my hourly charge.
I'm sure that the situation varies a lot according to the nature of the work and the trade/profession concerned. In my world, one of the very first questions one almost invariably gets asked is about one's 'hourly rate', and if someone based in central London quoted a much higher figure than, say, a person based in rural Cornwall or Wales, they simply would not get any work!
Basically I have arrived at a 'London rate' that works for me and I don't see why that should be a problem.
If that rate is calculated 'reasonably' that's fair enough. Customers/clients in London will undoubtedly expect and accept a much higher rate than they would in some different places "because that's how it is" - but that doesn't stop me asking whether "that's how it should be", at least in some contexts.
Despite what you and others may think, I am not being awkward or argumentative for argument's sake but, rather, genuinely am interested to know the answer to the "Why?" question - since I suspect that, at least in some cases, the answer may be "because that'show it is"! As I've said, there are certainly situations in which the cost of services, and maybe goods, is justifiably appreciably higher in places like London - particularly when 'premises' are involved, but I'm far less convinced in some other contexts (trades/professions).
17 years ago I did a job for a well known "multinational professional services network, and one of the Big Four accounting organizations"..... they accepted the range of 5 different labour rates on the 8 offices without comment (one based on the branch providing on site accommodation FOC). Leeds, Bristol and Birmingham were the most expensive due to the distance and 2 overnight stays, the cheapest of course being the 2 branches most local to me.
The 'total' is obviously the most important bottom-line for a customer/client, but everything depends on how 'reasonably' your (differing) totals were calculated.
If you merely took the 'hourly rate' you would charge for work within walking distance if you lived in, say, rural Wales and added to it a genuine estimate of travelling costs and some reasonable amount of remuneration for 'travelling time' and 'being away from home time', then I think that would be fine, and fair to everyone. However, I suspect that a good few people in that position would charge a higher hourly rate for work in an 'expensive' place (like London), before adding on those legitimate 'addons' - solely because "rates are higher in London".
As a matter of interest, to help my understanding, if you lived in an expensive part of London and worked as a full-time in-house (no travelling) employee at a site within walking distance of your home, would you expect a higher hourly rate of pay than if you were in exactly the same situation, other than living in some very rural part of the UK? Similarly, what if you were self-employed and (largely as is the case for me these days, although not in the past), virtually all of your work was undertaken 'remotely' ('from home') - would you then feel that you should charge appreciably more if you were doing it from your home in central London than if your home were somewhere very rural and 'cheap'?
In other words, I suppose what I'm really asking is whether your 'London rates' are much higher than they would be elsewhere simply because you have added a genuine estimate of travel-related overheads etc., or is it at least partially because 'London is an expensive place'?
