taxes in France
If I was in your position I will avoid to pay taxes in France
If you are paid in Uk you can be officially resident in UK (at the location of your company for example, plenty of other solutions, mail boxes...). Do not forget you have to be 183 days in a country to be resident and with your activity, I don't think you will reach this amount.
I am french, I have worked for some times in UK and I have appreciated to be in UK for the total amount of paid taxes. However housing is so expansive in UK that it may be more interesting to be in France.
Do not rush to pay your taxes in France, study carefully your situation.
Take care and best regards
