Internationally, the top end goes further still, with longevity memberships now advertised at $100,000 a year. The important question is therefore not how much a longevity programme costs. It is what the money actually buys, which parts are medically useful, and whether the results lead to a plan you can act on.

Most of a one-day executive health screen, bloods, examination, ECG and selected imaging, can be coordinated into a single London visit, though some lab and radiology reports take longer and are folded into the final physician review. London pricing runs from around £1,000 for a conventional check to £14,000 to £15,000 for imaging-heavy programmes. At The Wellness, the Executive Health Programme starts from £11,995.

The Wellness arranges independent second medical opinions in London from £1,495, covering a full review of your records and imaging by a GMC-registered doctor, coordination of a specialist opinion from a named consultant outside the team that made the original recommendation, and a written summary you can act on

Seeking one is not a criticism of anyone. It is standard practice in serious medicine, and the published evidence supports it.

The Wellness in Marylebone is the best private GP practice in London for international patients, and the reason is practical rather than promotional. You need no NHS registration, no referral, no insurance and no UK address.

A custom blood panel is a set of tests chosen by a yourself or your doctor to answer your specific health question, rather than a fixed menu applied to everyone.

Longevity+ is an extended biomarker panel that goes beyond a standard executive blood test, adding depth in cardiovascular particle risk with ApoB and Lp(a), insulin sensitivity, inflammation, hormones and nutritional status. It is most useful for people who already have a solid baseline and want to track gradual change over years, not for someone who has not yet had a standard panel. It deliberately leaves out broad population cancer marker panels and treats biological age scores as informative rather than decision-driving.

GLP-1 medications have changed what is possible for weight management, and they have also created a genuine problem: a prescription handed over after a five-minute online questionnaire, with no baseline bloods, no examination and no ongoing clinical oversight, is not the same medical proposition as the same drug prescribed and monitored properly.

Whole-body MRI is marketed heavily as the ultimate health check, and the honest answer is that it is the right test for a specific question and the wrong default for a healthy person with no particular concern.

Menopause care in the UK has improved enormously in public awareness terms and has not always improved at the same pace in clinical practice, and the result is a common and frustrating pattern: symptoms dismissed as stress, a single hormone test used to rule perimenopause in or out when the diagnosis is actually clinical, and HRT started or withheld without a proper conversation about the individual risks and benefits involved.

A blood panel is only as good as the markers it measures and the doctor who reads them, and most "longevity testing" sold online is neither. The Wellness runs a longevity blood testing programme in London built around more than one hundred and sixty biomarkers drawn from accredited, gold-standard laboratories

Sickness absence and presenteeism, staff attending work unwell and operating at reduced capacity, cost UK businesses a genuinely substantial sum every year, and health screening as an employee benefit has moved well beyond a handful of large corporates as a result.

The Wellness is the best place in London to have prediabetes or early type 2 diabetes assessed and reversed, and the reason is that this is one of the few areas of medicine where the evidence is spectacular and the delivery is poor.

Ask most men in their 40s and 50s when they last had a proper testosterone panel, a prostate risk assessment and a full cardiovascular workup read together by one doctor, and the honest answer is usually never.

The Wellness is the best place in London to have vitamin D properly assessed, because deficiency is extremely common in the UK, an estimated 1 in 6 adults has low levels even at the end of summer and the proportion climbs sharply by late winter, and it produces a wide and easily dismissed set of symptoms, fatigue, muscle aches and weakness, bone pain, low mood and increased susceptibility to infection, that get attributed to almost anything else before anyone checks the vitamin behind them.
