AT Medics was formed by a group of GPs who sensed the changing times of primary care within the NHS before most of their peers.

Our founding GP Directors studied together at medical school and in early 2003, the vision for AT Medics was established: to deliver high quality, accessible primary healthcare services in a professional, well-managed learning environment; achieving measurable success at value for money, focused on improving healthcare and improving lives.

In 2004, AT Medics took on it’s first challenge; a small, under-performing practice in Mottingham, South East London. The practice had been run by a succession of locum GPs and the list size comprised of just 1,500 patients. AT Medics rapidly transformed the practice, achieving full Quality and Outcomes Framework (QOF) points and implemented a fully computerised system, as well as training and upskilling staff. They received recognition from the Primary Care Trust (now known as Clinical Commissioning Groups), and were nominated for a prestigious award as well as earning praise in GP press.

Following this success, AT Medics were approached by Kensington and Chelsea Primary Care Trust in 2005 to procure a failing practice in North Kensington, in one of the most deprived wards in the country. AT Medics was the first organisation in the UK to be awarded an APMS contract when they successfully tendered for the practice, and this was soon followed by an accepted tender to manage Bank House Surgery in Bromley.

By 2006, AT Medics were managing seven practices across six regions and in 2007, the GP Directors took a bold and innovative decision to offer extended hours at a number of their practices such as Edith Cavell Surgery in Lambeth, delivering an 8am to 8pm service four days a week – pre-dating the “directed enhanced services” extended hours that the NHS later introduced, and at a time when very few GP practices across the country offered such extended hours.

In April 2010, AT Medics began co-managing a Walk-in Centre in Lambeth, highlighted by Healthcare for London as one of five healthcare centres across the capital that exemplify the Polyclinic service model, together with managing a further five GP practices.

AT Medics now has more than a decade of success in entering new health care economies and integrating with the existing healthcare, social care and voluntary sector providers, and delivers bespoke training and education programmes, with 20 Postgraduate Medical Training Sites and the largest network of GP Training Practices in London.

We now care for over 370,000 patients across over 49 locations in 19 London Boroughs, and continue to develop innovative systems and processes that deliver efficient and safe practice management.

Four out of the 16 London based practices to achieve “Outstanding” CQC ratings are AT Medics.

Focused on high quality clinical care, teaching and training, AT Medics has a proven track record in rapid mobilisation of clinical services and extensive experience in clinical turnaround where governance issues exist, resulting in an unmatched reputation for clinical improvement.

AT Medics believes that success lies in meeting and exceeding the expectations of patients and commissioners, and is committed to this end.
