GP advice service

Non-urgent medical enquiries

GPs and practice staff within the Trust’s eight referring CCGs (Hammersmith & Fulham, Central London, West London, Ealing, Hounslow, Harrow, Brent and Hillingdon) can email or telephone our medical specialists with non-urgent clinical enquiries, through our GP advice service. The service provides general clinical advice for the specialities listed below and should not to be used for administrative or appointment queries.

If you are a patient and have an enquiry please contact our patient advice and liaison service (PALS).

The GP advice phone lines are open from 12.00 to 14.00, Monday to Friday, unless otherwise stated, and we aim to answer emails within 24 hours (except on weekends and bank holidays).
