Hearing aid service

We provide a comprehensive hearing aid service including several specialist clinics, seeing patients through each stage of their treatment from the initial assessment of hearing status to the hearing aid fitting and follow-up care

We mainly fit the latest digital 'behind-the-ear' hearing aids. Specialist devices such as CROS/ BiCROS hearing aids and 'in-the-ear' hearing aids can be provided if there is a medical reason to do so.

We work mainly from Addenbrooke’s Hospital with peripheral clinics also held at Newmarket Community Hospital, Saffron Walden Community Hospital and the Princess of Wales Hospital, Ely.

All enquiries or requests to be seen at a peripheral clinic should be made to via us.

What to expect at your appointment

Hearing assessment

  • A typical hearing assessment lasts up to 1 hour.
  • The audiologist will take a detailed history from you, recording your hearing difficulties and lifestyle.
  • A hearing test will be performed where you wear some earphones and listen to sounds at different tones and levels.
  • You will be asked to indicate if you have heard the tones by pressing a button.
  • You may also have a test to check how well you can hear spoken words by simply repeating short words spoken at different levels.
  • The results of your hearing tests will be used by the audiologist to help you decide what the best treatment option for the particular hearing difficulties you have.

If you require a hearing aid we might take some impressions of you ear(s) to make an ear mould, although some people with mild hearing loss may be able to use a soft open ear piece called an open fitting that doesn’t require an ear mould.

We will then arrange an appointment to have the hearing aid(s) fitted.

Hearing aid fitting

  • A hearing aid fitting appointment takes approximately 1 hour.
  • The audiologist will check the fit of your ear mould (or open fitting) and ensure that it is comfortable.
  • We then make several recordings of the hearing aid to ensure that it is working to the correct levels for your hearing loss and that you are happy with the way the hearing aid sounds.
  • The audiologist will show you how the hearing aid works and how to look after it.

At the fitting appointment you will be given several leaflets which contain all the information you need to help you look after your hearing aid and where you can get support if you are having problems.

If appropriate the audiologist will arrange for a follow up appointment to check how you are getting on with your new hearing aid.


If you would like to be assessed for a hearing aid and do not already have one, visit your general practitioner (GP) who can refer for a hearing assessment. This will either be carried out at Addenbrooke’s Hospital or possibly a different location dependent on your eligibility.

In some cases your GP may refer you to an ENT (Ear, Nose and Throat) clinic for a medical opinion before you can be assessed for a hearing aid. The ENT clinic will then refer you to the Audiology Department if appropriate.

If you are already an Audiology patient at Addenbrooke's and you feel your hearing has worsened you should contact the Audiology Department directly by telephone or letter and a reassessment appointment can be made if appropriate.

Looking after your hearing aid

At your hearing aid fitting you will have been given an instruction leaflet for your hearing aid. This explains how to:

  • switch the hearing aid on and off
  • change batteries
  • operate the controls

If the hearing aid needs repairing you can:

Hearing aid repair and maintenance

Please note that due to Covid-19 restrictions, our open access repair clinic is closed. Hearing aids can be posted in - see details about our postal service below.

If the hearing aid needs repair or maintenance you can send your hearing aid(s) in appropriate packaging, with your brown record book and a stamped self-addressed envelope (with a large letter stamp) for return to you.

Our address is:

Information on hearing aid maintenance can also be found by searching C2Hear Online on their website or YouTube. You can also request batteries and tubes using the online form. Please contact us if you feel you need an appointment.

Lost or damaged hearing aids and earmoulds

Your hearing aid is a valuable and delicate instrument, please treat it with the utmost care. NHS hearing aids and earmoulds are provided on loan to people with a hearing impairment and remain NHS property.

If your hearing aid or ear mould is lost or damaged, please contact the audiology department. You may be charged to replace the lost or damaged hearing aid. The lost/damaged aid panel will decide if you will be charged, as you may be exempt. There is a standard fee of £65 per aid.

You have the right to appeal against any possible charge. Appeals must be made in writing, to the appeals committee, via the Head of Audiology, or verbally via the PALS office, who will make a record of the appeal and forward it by e-mail to the Head of Audiology.

The following minimum information is required for the appeals committee to consider each case;

  • The circumstance of the loss.
  • The age of the hearing aid.
  • The number of previous lost hearing aids.

The panel will write informing you of their decision. If the decision is made to apply the charge, you will receive an invoice from the Trust's invoicing department.

Address for appeal letters:

Box 94
Addenbrooke’s Hospital
Hills Road

Face masks

Some hearing aid users have found it difficult wearing face masks with hearing aids.

This helpful video from RNID gives some useful guidance. If you lipread it can be difficult when others wear face masks.

Transparent face masks are available to allow lipreading. Please ask the audiologist if they are able to wear a transparent face mask if you feel this would be helpful during your appointment.

Cambridge Adult Hearing Services (CAHS) (patients over 50)

Patients over 50 years of age with straightforward age-related hearing loss are suitable for the CAHS service. They will not be seen by Addenbrooke’s but will instead be seen by another provider, currently Specsavers. They can expect the same high quality service regardless of where they are seen. People who do not meet the referral criteria or those with specialist hearing needs will continue to attend Addenbrooke’s Hospital. If you are unsure whether you should be seen by CAHS or Addenbrooke’s, please phone Addenbrooke’s Audiology department for advice.
