Coronavirus: allergy service update

Due to increased demand on the hospital due to the coronavirus (COVID-19) pandemic we are having to make significant changes to our services which may require cancellation of appointments.


We are attempting to contact all patients with a future scheduled appointment.

In some cases we are changing appointments to a telephone consultation.

Some appointments may be cancelled without a future date being arranged at this stage. If we cancel your appointment you will remain on our waiting list and we will contact you in due course. Some patients may be discharged back to their GP and we will write to you if this is the case.

For all appointment queries, please email Please avoid calling our service if you have access to email.

Do not email this address for COVID-19 vaccine allergy queries. Instead, ask your GP to submit an advice and guidance (A&G) request on e-RS.

Exisiting patients

If you are an existing patient who has previously been seen in our service and need advice from the clinical team, please see below for the appropriate option.

Contact us by email for: 

  • queries regarding your appointment or the contact details we have for you
  • appointments.

See our frequently asked questions for further information. If your query is not covered, please either email or call us as appropriate.


We are doing everything we can to support GPs and your patients during the coronavirus (COVID-19) pandemic. If you need advice from our clinical team, please use the current advice and guidance channels or Consultant Connect to speak to a senior clinician immediately.


We would encourage you to contact our clinical team before making an urgent referral. We are vetting all referrals.

We will be contacting urgent patients but we are not currently booking routine patients and so there may be a significant delay before seeing your patient.

Please consider this before making any referral as our capacity to see new patients is very limited.

Our frequently asked questions page has answers to common questions we have received from patients.


Please visit the main Trust coronavirus (COVID-19) page for more information.
