£65. Ours hadn't been done in a while, he also took the edge off some of the hammers, and another bit of maintainance. Was here about 1.5 hours. He didn't tune it to concert pitch (that would have cost more, he implied, and none of us play, so we can't exactly tell the difference, anyway!) I think £50-£70 is typical around here (Norfolk).
Ours is big & old... the tuner told me that to buy equivalent quality new would cost £20k, so... it may be complicated to get tuned.
