<prompt> Fingqa isihloko: Izinkampani zamandla zaseBrithani ezinkulu eziyisithupha zilungele ukwenza ama-118 ekhaya ngalinye naphezu kokwehla kwamanani kagesi nogesi. Inzuzo evamile izinkampani zikagesi eziyithola kumakhasimende iye yakhuphuka yafinyelela ezingeni eliphakeme kunawo wonke lamaphawundi angu-118 ikhaya ngalinye. Lokhu kukhuphuke ngengxenye eyodwa kwezintathu kunonyaka odlule futhi kungaphezu kokuphindwe kabili kunalokho izinkampani ezazikwenza eminyakeni emibili edlule. Lokhu kukhuphuka kuwumphumela oqondile wokwehluleka kwezinkampani ukudlulisela ukwehla okukhulu entengo yokuthengisa igesi nogesi. Umlawuli wemboni i-Ofgem ulinganisela ukuthi izindleko ezijwayelekile zokuthengiswa kwegesi nogesi ziye zehla zisuka ku-633 ekhaya ngalinye ngonyaka odlule kuya ku-553 - ukwehla ngo-80. Kodwa izibalo zayo zezikweletu zamakhaya zamaphethiloli amabili zibonisa ukwehla okuncane okungu-60, okuziletha ngokwesilinganiso sika-1,295 ngonyaka - cishe amaphesenti ayishumi ayo ayizinzuzo. Izinkampani Eziyisithupha Ezinkulu iBritish Gas, i-SSE, i-Npower, i-E.on, i-EDF ne-Scottish Power ziye zakwazi ukuthola imali ngokugcina amanani azo aphezulu ebusika. Baye bamemezela ukuncishiswa okuncane okungamaphesenti angu-5 noma ngaphansi, kodwa lokhu ngeke kwenze umehluko omkhulu ezindlekweni zasendlini. Lokhu kubonakala kuwukufuna inzuzo kungakhathaliseki ukuthi unyaka odlule wawungomunye weminyaka efudumele kakhulu emlandweni futhi ukusetshenziswa kukagesi nogesi emakhaya kwehle ngamaphesenti angu-14 uma kuqhathaniswa no-2013. Kuzokwengeza ekufuneni ukuzamazamisa phakathi kwezinsolo zokuthi abahlinzeki behluleka ukuncintisana ngentengo kanye nensizakalo yamakhasimende. I-Competition and Markets Authority icela abahlinzeki ukuba bachaze ukuthi kungani izindleko eziphansi zokuthengisa nge-wholesale zingazange zidluliselwe futhi i-Which? ifuna uhlelo olusha lokubeka amanani kagesi. Leli qembu labathengi lisikisela ukuthi iziphathimandla kufanele zibeke intengo efanelekile esekelwe ekuhlolweni kwezindleko, futhi izinkampani kufanele zincintisane ukuze zifane noma zibe ngaphansi kwaleyo ntengo. Ishadi elibonisa ukwehla kwezindleko zamandla okuthengisa kanye nokwanda kwamanani angaphambi kokukhokhiswa kwentela kwabakhiqizi bamandla amakhulu. URichard Lloyd, we-Which?, wathi: Abathengi bazobuza ukuthi kungani ama-bill abo engazange ancishiswe kakhulu ngesikhathi sokukhuphuka kwenzuzo nokwehla kwamanani entengo. Izindleko zamandla zihlala ziwukukhathazeka okuyinhloko kwabathengi, ngakho sidinga...  <response>: Kulindeleke ukuthi amanani entengo kagesi nogesi ehle ngonyaka ozayo. Kodwa izinkampani zamandla zibhekene nokwenza inzuzo ekhulayo, ngokusho kwe-Ofgem. Lo mkhakha njengamanje ucwaningwe ngophenyo lomncintiswano oluphelele. Isambulo sakamuva kulindeleke ukuba sibeke ingcindezi kwezepolitiki kulo mkhakha.
