Paying tax on private pension lump sum, but resident and tax payer in France.

Hi, I have a small private pension , value around £18,000. I am a resident and taxpayer in France and have been for the last 25 years, where i live and work. I would like to take a trivial commutation (the total lump sum) and understand that i can have 25% tax free, but the other 75% is taxed in the UK?? France or both countries. Would i have to pay tax twice????, and if taxed in the UK what percentage. many thanks for your time. Mike

Please find guidance:
