Your letter should clearly outline the issue or experience you had and should ask for it to be investigated under the NHS Complaints Procedure. If you are writing on behalf of someone else who is a patient, rather than for yourself, you must show that you have the patient’s permission.

Helpful tips

Be brief

  • Try to keep your complaint to no more than two pages
  • Be careful not to lose your main points in a long letter
  • If the complaint is long and complex attach a log sheet or diary of events with details

Be clear and straightforward

  • Use short sentences
  • Don’t be afraid to say what has upset you, but avoid aggressive or accusing language
  • Don’t repeat yourself

Be constructive

  • Your complaint is an opportunity to improve things
  • Put your concerns politely, but firmly
  • Explain what you would like to achieve as a result of your complaint for example an apology, an explanation, a service improvement, any other remedy

Keep copies

  • Keep a copy of all letters or emails sent and received, in date order and a note of all telephone calls made.

Send photocopies of documents, not originals

  • Keep the original documents in your possession.

Make sure your letter is received

  • You may wish to send it by guaranteed or recorded delivery.

What happens next?

You should receive a letter of acknowledgement within three working days.

The NHS should contact you to discuss your complaint and arrange a plan to resolve your concerns with you. This means that they will discuss how best to resolve your concerns and what you hope to achieve from raising them. They should also agree with you a timescale for resolving the issues and keep you informed of progress. The suggested timescales can be influenced by things like how many staff they need to speak to, how easy it is for them to access your medical records and if other NHS organisations are involved in your complaint. If there is a problem in keeping to this timescale they should contact you before it expires to agree an amended timescale.

If your complaint involves a service that is provided in partnership with the NHS, the organisation that received your complaint will approach the other organisations. Between themselves they will agree who will:

  • Take the lead in handling the complaint
  • Be your point of contact and take responsibility for communicating with you
  • Co-ordinate the handling of the complaint and any investigations
  • Ensure you receive a single response, addressing all issues agreed at the outset.

Complaint letter, sample

From: Mrs A Smith
1 The Avenue,
Your town,
Tel: 010 232 3205

To: Helen Clarke
The Complaints Manager
Petersfield Surgery
4 Main Street
Your town

30th March 2013

Dear Helen Clarke

Re: NHS Complaint – Mrs A Smith, DOB 19 May 1963

I am writing to complain about the way I have been treated by Dr Hayton at Petersfield Surgery.

I was seen by Dr Hayton three times, on 24th April, 31st May and 10th December 2012. He did not examine me or do any tests. I feel that he did not take my symptoms seriously and said my problem was due to stress and that I should take things easy.

I was feeling so unwell and found his dismissive attitude upsetting. I was worried so I made an appointment to see another doctor in the practice. I do not know his name but it will be in my notes.

This doctor examined me on 7th January 2013 and arranged for tests. These showed that I was diabetic. I was prescribed medication and a special diet and I am now feeling much better. During the period from April 2012 to January 2013, however, I suffered with several infections, sleepless nights and I was very distressed.

I have tried to raise my concerns with Dr Hayton but he would not listen.

I would like the following points addressed in response to this complaint.

  • Is my medical condition poorer as a result of my diabetes not being detected and diagnosed by Dr Hayton on previous appointments?
  • Why did Dr Hayton not order any tests?

Along with answers to my questions, I would now like:

  • Dr Hayton’s attitude to patients to be reviewed
  • Dr Hayton to explain why he did not listen to me or examine me
  • An apology from him for the unnecessary stress and poor health I suffered because of his inadequate care
  • To know what arrangements the practice has for reviewing the listening skills of the doctors.

I have had very good care from the practice in the past, in particular from Dr Conner until he retired. I was then moved to Dr Hayton. I would like to regain confidence in the care provided by the practice.

I would appreciate it if you would carry out a full investigation into my concerns, and provide a response in accordance with the NHS Complaints Procedure.

I look forward to hearing from you.

Yours sincerely

Mrs A Smith

Who do I complain to?

 If your complaint is about a hospital or an ambulance service, contact the Complaints Manager or the Chief Executive of the NHS Trust.

If you are not clear where to send your complaint, ask for advice from the Patient Advice and Liaison Service (PALS) or the Complaints Department at the hospital or from your local NHS Complaints Advocacy service. Alternatively, most hospital Trusts have details of how to contact them about complaints on their website.

For complaints about service provision in primary care or by independent providers such as your GP, dentist, optician, pharmacist, health centre or other independent NHS contractors, you have two options:

a) You can complain directly to the NHS organisation and service by contacting the person in charge of complaints. In most GP and dental practices, this will be the Practice Manager.


b) You can complain to the Commissioner of the service.

Note: If you choose to make a complaint directly to the organisation (option a), and you are not satisfied with their response you cannot then raise the same issue with the Commissioner of the service but must go directly to the Parliamentary Health Service Ombudsman (PHSO).

If your complaint concerns more than one NHS organisation you only need to send a letter to one of the organisations. They will liaise with the other organisation(s) involved and provide a coordinated response.

Complaints involving non NHS organisations

There are separate complaints procedures for social care complaints or complaints about privately arranged services. Although the NHS Complaints Advocacy service cannot support complaints in these cases, we will point you in the right direction of where to get help.

The NHS Complaints Advocacy service can only support you in complaining about NHS-funded services that include a social care element. An example of this might be you wanting to make a complaint to the hospital about your discharge but part of the complaint relates to social care services provided when you arrived home.

If your complaint involves a service that is provided in partnership with the NHS, you only need to complain to one of the services.
