Great news about your ESA award, thanks for letting us know and for your kind words about B+W
Without full details of your financial circumstances (which it is not appropriate for us to have), it is impossible for us to tell whether you would be better off on IR or C ESA. You can try modelling your circumstances on a site such as turn2us, or you can see a CAB/welfare advisor and ask them to do a 'better off' calculation on your behalf.
