Disastrous. New boiler installed november 2021. Never worked properly, central heating intermittant at best. 29 Engineers later still not working in spite of flushes (x2) replacement pumps (x2) numerous leaks as a result of work attempted so bought 2 new oil filled electric radiators as emergency heating after 2 winters without any central heating. Latest engineer came 2 days ago after witnessing boiler cutting out constantly. Now waiting for "someone" to come and mend it. No reponse from SH about WHEN so maybe they are hoping us OAP's will just fade away from hypothermia.
