The service provides a comprehensive diagnostic and treatment service for adults with sleep disordered breathing, in particular Obstructive Sleep Apnoea (OSA).

You may need the service if you have consulted your GP about:

  • Excessive snoring
  • Breathing problems while sleeping
  • Feeling excessively sleepy in the daytime

The team provides treatment with Continuous Positive Airway Pressure (CPAP) on the NHS for those with a confirmed diagnosis of OSA.

Referral process

You will first need to consult your GP, who will need to refer you.


We have access to a comprehensive range of diagnostic tests ranging from simple home monitoring to detailed in-patient sleep studies in our dedicated Sleep Laboratory.

We will review the studies on a weekly basis and if the results show you need treatment for OSA, our dedicated Specialist Sleep Nurse will spend more time with you to explain your treatment and provide you with all the equipment you need.

Drop-in sessions (existing patients)

Our Wednesday drop in clinic hours are between 8.00am and 12.00pm - no appointment necessary.

Otherwise, please contact us for a different time (this must be booked - please do not turn up without prior arrangement).

Clinics are by phone unless otherwise arranged.

Face-to-face troubleshooting appointments can be made, but these must be booked in advance.
