Not the BUPA one but I've recently gone for a 360+ Health Assessment with Nuffield Health. https://www.nuffieldhealth.com/health-assessments/360-health-assessment Looks comparable to the "Be Ahead" version with BUPA.
It was excellent, very through, lots of advice and guidance and a full test work up which I'd never get via GP, I even had a mammogram which I'm not entitled to for another 7 years on the NHS. Its actually the second one I've had so I was able to compare my results to see what I'd improved, etc.
