You have no liability to CGT. Ignoring acquisition/disposal costs and any enhancement expenditure (which would only reduce the gain):
Disposal £121,000
Acquisition £14,750
Gain £106,250
Private residence relief 15 + 3 out of 25 years = £76,500
Net gain £29,750
Lettings relief lower of PRR, gain arising by reason of letting and £40,000 = £29,750
Net gain = £0
Yes, you do have to declare this disposal in your 2010-11 tax return in order to claim the reliefs.
