i agree with all of the above, but especially the bitabout charging the right price. we work on about £26 per hour ...thats for 2 of us ..so about £13 per hour each....so if a house takes 1/2 hour charge £13....15mins charge £6.50....this is for domestic....commercial charge more around £30 per hour.
be nice to know what others charge....but dont be drawn into charging lower to get the business...it doesnt work
