The rules on sanctions in this chapter apply if you come under the universal credit (UC) system, whether you are getting UC, jobseeker’s allowance (JSA) or employment and support allowance (ESA) (see here). JSA or ESA under the UC system are called new-style JSA and new-style ESA. If you claim JSA, that is only payable under the UC system. If you get ESA but you do not yet come under the UC system (ie, you get old-style ESA), see here.
