Why London Has a Weight Loss Problem (and What’s Changing)

Like most of the UK, London has seen a steady rise in overweight and obesity over the past two decades, and the pattern is not evenly spread across the capital. Prevalence tends to be higher in outer London boroughs than in central London, and it correlates closely with deprivation, as tracked by the Office for Health Improvement and Disparities (OHID), which publishes borough-level data as part of its Public Health Profiles.

How the five London Integrated Care Boards each set local policy

Since 2022, NHS commissioning in London has run through five ICBs: North West London, North Central London, North East London, South East London, and South West London. Each ICB sets its own local pathways, referral criteria, and capacity for specialist weight management services, within the framework set by NICE guidance. In practice, this means a patient’s exact NHS route, and how long they may wait for it, depends on where their GP practice sits.

The gap between eligibility on paper and capacity in practice

Being clinically eligible for NHS-funded weight management support is not the same as being able to access it quickly. Specialist Tier 3 weight management services across London, which are typically the route to NHS-funded GLP-1 based treatment, have limited capacity and long waiting lists in most boroughs. This gap between who qualifies in theory and who can be seen in a reasonable timeframe is a major reason many Londoners look at private or online routes instead.

We would encourage readers to check current waiting times with their own GP practice or ICB directly, as these change over time and vary considerably across London.

Your Three Routes to Weight Loss in London

Broadly speaking, there are three ways to access medically supported weight loss treatment in London. The table below gives a general comparison; costs and waiting times will vary by provider and by individual circumstances.

The NHS route across London’s ICBs

To access weight loss medication through the NHS, most patients need to be referred into a specialist weight management service and meet criteria set out in NICE guidance. Referral routes, thresholds for access, and waiting times differ by ICB, so it is worth speaking to your own GP practice about what applies in your borough.

Private in-clinic services in London

Private weight loss clinics operate across London, including in areas such as Central London, Canary Wharf, Croydon, Ealing, and Islington. These clinics generally offer in-person consultations and monitoring, which suits patients who prefer face-to-face contact, though this often comes at a higher cost than remote options.

Online pharmacy services, including The Care Pharmacy

Regulated online pharmacies such as The Care Pharmacy offer a fully remote pathway: an online consultation, clinical review by a UK prescriber, and delivery of medication direct to your door anywhere in London. This route suits patients who want convenience without sacrificing clinical oversight, provided the pharmacy is properly regulated.

Medical Weight Loss Treatments Available in London

At The Care Pharmacy, we offer a range of licensed weight loss treatments, so that a plan can be matched to individual circumstances following a clinical assessment. All of the following are Prescription Only Medicines and require an online consultation before supply.

Mounjaro (tirzepatide)

Mounjaro is a once-weekly injection containing tirzepatide, a dual GIP and GLP-1 receptor agonist. It works by acting on appetite-regulating pathways to reduce hunger and increase feelings of fullness, and is licensed in the UK for weight management in adults who meet specific BMI criteria, alongside diet and physical activity.

Wegovy (semaglutide)

Wegovy is a once-weekly injectable GLP-1 receptor agonist containing semaglutide. Like Mounjaro, it reduces appetite and helps with satiety, and is licensed for weight management in adults meeting relevant BMI thresholds.

The Wegovy pill

For patients who prefer to avoid injections, we also offer the Wegovy pill, an oral tablet form of semaglutide. Eligibility, dosing, and monitoring follow the same careful clinical process as the injectable form, and suitability is assessed on an individual basis.

Saxenda (liraglutide)

Saxenda is a daily injectable GLP-1 receptor agonist containing liraglutide. It was one of the earlier GLP-1 medicines licensed for weight management in the UK and remains a suitable option for some patients, particularly where a daily rather than weekly dosing schedule is preferred.

Nevolat

Nevolat is a daily weight loss injection offering a further dosing option for patients for whom a once-daily treatment schedule suits their routine better than a weekly injection. As with all our treatments, suitability is confirmed through clinical assessment before any prescription is issued.

Orlistat

Orlistat works differently to the GLP-1 and dual-agonist medicines above. Rather than acting on appetite, it works in the gut to reduce the amount of dietary fat absorbed from food, taken alongside a reduced-calorie, lower-fat diet. It can be a suitable option for patients who are not eligible for, or do not wish to use, injectable treatments.

A note on safety

Every one of these medicines carries potential side effects and is not suitable for everyone. A proper clinical assessment, covering your medical history, current medications, and any contraindications, is essential before any prescription is issued. We would strongly caution against sourcing any of these medicines from unregulated sellers who skip this step.

Who Qualifies? BMI and Eligibility Explained

Private prescribing criteria

As a general guide, private prescribing for GLP-1 and dual-agonist weight loss medicines in the UK is typically considered for adults with a BMI of 30 or above, or a BMI of 27 or above where a weight-related health condition is also present, such as type 2 diabetes or high blood pressure. Exact thresholds can vary slightly by medicine and by prescriber, which is why an individual assessment matters more than a general rule of thumb.

NHS criteria across London ICBs

NHS eligibility criteria are generally aligned with NICE guidance but are applied locally by each ICB, and capacity constraints mean meeting the criteria does not guarantee prompt access. If you want to explore the NHS route, your GP practice is the best starting point for confirming what applies in your specific borough.

Who should not take GLP-1 medicines

These medicines are not suitable for everyone. They are generally not recommended during pregnancy or breastfeeding, and caution or exclusion applies for people with certain conditions, including a personal or family history of certain thyroid cancers, a history of pancreatitis, or significant gastrointestinal disease. A full medical history review during your consultation is how this is properly assessed, rather than a general checklist.

Work Out Your Starting Point

A BMI calculator can give you a general sense of where you sit against the criteria above, but it is only a starting point.

Your full eligibility is confirmed through a proper clinical consultation, not a calculator alone.
