Paddington square construction works next to St Mary's Hospital

Patients and visitors to St Mary’s Hospital may experience some disruption caused by nearby construction works for the Paddington Square development (located between Praed Street and South Wharf Road). We apologise in advance for any impact these neighbouring works may have for our patients and visitors. 

While the developer has put in place a range of mitigation and monitoring measures, we anticipate that there may be some disruption caused by additional noise, dust and vibration. If patients and visitors wish to raise any issues about the impact of the construction works on their care and treatment, then we would ask them to speak to our staff or contact the patient advice and liaison service (PALS).

I was delighted to find that I could now book an appointment for a sexual health check-up and wasn't disappointed. I was in and out in 25 minutes and my lovely nurse couldn't have been more friendly, helpful and thorough.

The staff at the Jefferiss wing were discreet, friendly and knowledgeable. I'd highly recommend.
