If it is a G-reg, it cannot be rented out unless maintained accordingly.
Okay, so the insurance is significantly more expensive - ~3000 pounds per year according to this one sample.
That's a significant amount of money to get back in rental fees.
But what do the increased maintenance requirements mean, practically speaking? And I understand you can do certain things (up to a 50-hour check?) as an owner yourself. Does that still apply?
