Charities We Support

Chartwell Cancer Trust

ERSG is proud to be a Corporate Patron of The Chartwell Cancer Trust. The Trust is a registered charity providing financial support for the Chartwell Cancer and Leukaemia Unit in the Princess Royal University Hospital, Farnborough, Kent.

The Unit serves one of Europe’s largest metropolitan borough areas, which has over one million residents. It provides patients with a comfortable environment in which to receive care from the professional, multi-disciplined team who address their symptom control and pain relief. NHS budget policy dictates the service levels and equipment availability in the Chartwell Unit. There are shortfalls, which The Chartwell Cancer Trust helps to overcome.

Building a Future for Peruvian Children

Working in and with the Lajas district since 2008, the Association was registered in Peru in 2009 and exists to help the most disadvantaged children in this area obtain a better future for themselves, so that this type of support will not be needed in the future.

Lajas is a district of 36 communities in the northern Andes of Peru. The majority of people live by subsistence farming and many lack the means for more than basic survival - almost one third live in extreme poverty (Peruvian National Census 2007). Some families have been abandoned by their fathers who have left to seek work elsewhere and have never returned.

As a result a quarter of children do not go to school and have no prospect of a future. The Association helps disadvantaged children who did not attend school previously, attended very irregularly, or attended but without the necessary equipment to enable them to benefit.
