Maps like the Great British Public Toilet Map can help you to check in advance where the nearest public toilets are.
The site will tell you how accessible the toilets are, and is particularly handy if you suffer from incontinence or digestive problems and are worried about needing to find a toilet urgently.
The Radar NKS Key
The National Key Scheme (NKS) offers disabled people independent access to locked public toilets around the country.
Toilets fitted with NKS locks can now be found in shopping centres, pubs, cafés, department stores, bus and train stations and many other locations in most parts of the country.
When you order a key you’ll also be able to order a list of toilets in your local area that are part of the scheme.
The Changing Places Scheme
People with profound and multiple learning disabilities, as well as other serious impairments such as spinal injuries, muscular dystrophy, multiple sclerosis or an acquired brain injury, often need extra facilities to allow them to use the toilets comfortably.
Changing Places toilets are different to standard disabled toilets because they have extra features and even more space.
You can plan ahead and search for Changing Places toilets in your area by using the Find A Toilet feature on their website.
Alternatives to Public Toilets
Pubs, restaurants and cafes with more than a few seats are required by law to have toilets for their customers, and most are happy to let you use their toilet facilities providing you’ve bought food or drink from them.
In some areas, businesses operate a Community Toilet Scheme. Under this scheme, shops and other businesses that have a toilet that’s normally just for staff can agree to let members of the public use their facilities on request. They may display a sticker in the window that you can look out for.
