Even though the weather is still relatively mild any marquee hire will now be going out with heating. The question is how much fuel do you allow for and what is reasonable?
As with many things it is best to preempt any potential head ache by telling the customer in advance. We would usually specify (both on the quote and verbally when erecting the marquee) any heating comes with 12 hours of heating. This would usually be plenty for any function – if the party starts at 7 tell them to fire the heaters up at 5 to warm the marquee up and if they’re still going at 5am then the alcohol will keep them warm!
By not specifying this you run the risk of customers running out of fuel whether that be gas or diesel. As with many things I only know this from personal experience but customers will be in the marquee the evenings beforehand using the heater only to find they’ve used up all of the fuel before the function.
This doesn’t of course apply to electric heaters though as discussed elsewhere they are only really suitable for very small marquees/gazebos. Diesel heaters have the advantage over gas in that customers will often be happy topping up the fuel themselves to save you going out to do so (you can even leave a spare canister and funnel).
Save yourself the headache and risk of a callout by making it very clear in advance how much fuel for the heaters you are supplying.
