One of the clubs I have flown from records the tacho but the charges are quoted/charged in hours on a formula of 1hr=0.8 tacho.....
In other words if you do 1 tacho you will be charged hourly rate*1.25 (which seems weird but I suppose it means they can quote a cheaper "hour" cost as other clubs locally advertise/charge by the tacho hour). It also means if you fly more economically you get more time for your pound.
In our group aircraft we charge ourselves £100 per tacho and the difference between that and the fuel cost goes in the kitty for maintenance etc. With the current fuel prices this means each hour we fly adds roughly £35 to the kitty (depending how lean/economically you fly).
I have never seen/come across a Hobbs but my selection of clubs/aircraft has so far been quite limited.

We charge brakes as claimed by the customer. We trust them to be honest and don't have any problems. Far kinder to the engine as people warm them up properly when they are not worrying about paying for the warm up.

Yet again as with thing aviation, people will always go out their way to take a simple set of "rules" and make them stupidly complicated.
Charge the hirer, "Brakes off-Brakes on", (Yes there is an element of trust) he should also on the paperwork record, TO-Touchdown for the engine/airframe logs. No problem with recording the Hobbs meter as it will act as a check on those who might make a "mistake" in their timings, as you all know the brain turns to mush after flying and number crunching can be tricky. Simples.
Tacho + 1.25 hobbs -.2 taxying etc etc, what a load of bolleux I'm afraid.

Our Aircraft are all fitted with Trakfax Flightmeters which record airborne time automatically. They are reset to zero at each 50hr check then read cumulatively to the next check.
This means that the meter reading at the end of each flight shows the time of that flight by reference to the reading at the end of the previous flight and also shows clearly the hours flown since the last maintenance check. The meter ignores taxying, ground running etc..
For charging and personal logbooks we add 10mins per flight to simulate chock to chock but without charging for the ground delays found at some airports.
The only downside becomes flying an aircraft without one and having to note down all the times....
