Keep in mind the fact that, when acessing whether you are protected from UK taxation under the tax treaty between UK and France, in order for UK to have taxing power, YOU must have a permanent establishment ("PE")(or "fixed base", depending on wording of applicable provision) in UK. The test is not whether the work is performed "from" a PE in UK.
For example, based on case law in this country (I am not sure whether there is any in UK), in the fairly typical situation where a self-employed consultant works on the premises of a client, even for an extended period, that would NOT be a PE of the consultant, because normally those premises, even if there is a designated office of the consultant, would not be under the control of that consultant.
