The Incorporated Society of Musicians is an organisation that provides support for professional musicians. They have surveyed 1400 private music teachers about their fees and found that:
In Central London, music teachers tended to charge between £30-£50/hour. Private music teacher fees in Greater London were a little less, ranging from £30-£40. In the regions of the UK, fees were generally between £25-£35.
43% of music teachers expected to increase their tuition rate over the next 12 months, and 35% had raised their fees the previous year, generally by between £1-£4 (though inner London teachers raised their rates by £5).
The ISM’s results are similar to results published by The Tutor Pages which indicated that the average fee charged by music teachers was almost £32/hour.
