Treatment costs vary and will depend on location, type of therapy, as well as on the therapist’s current workload. I have seen charges that range widely, but therapists will generally only charge what is required to enable them to continue providing their services and pay their own bills.
The cost may be upward of £50 per session (as of 2019), although costs vary depending on location, local economy etc.
Although this may, at first, sound expensive, psychotherapy work takes a great deal of ongoing training, vigilance and personal energy, and also additional time on cases outside of the consulting room. There are also fees to be accredited members of professional bodies such as the National Counselling Society, which are also there to ensure your continued safety. Add to all of this the rental of premises, heating, lighting, telephone, computer, stationary, and so on, and the cost is put into perspective.
Perhaps comparing what a garage mechanic will charge to fix your car, around £90+ an hour, or a restaurant meal for two, around £60+, puts life-changing psychotherapeutic fees in a little more in perspective.
If you ever find yourself needing therapeutic help but are also unable to meet the costs (e.g. your concerns may also be affecting your earning ability), ask the therapist or therapeutic organisation if they can help you for what you can afford. Your GP and local council may also be able to put you in touch with organisations that can help.
You may also consider group therapy as this is often cheaper, or free, but it is still extremely effective. Group therapy offers advantages, such as the support and understanding from others who are in a similar situation or facing difficult challenges, and hearing what others are dealing with can help us to realise that we are not so alone.
On-line therapy is also an option, for example, via Skype (search Google for “online therapy UK” to see a list of organisations in the UK).
Your welfare is important, so ask for concessions when you really need them, and if the therapist you ask does not offer reduced rate sessions, ask them if they know a therapist that will. (See the links at the bottom of my welcome page to search for therapists in your area).
