I hope you can get it sorted for GBP75. We gutted our kitchen three years ago this December, I plastered the walls, new oak floor, re-wired and then built the kitchen from scratch with bespoke surfaces, new dishwasher. An all new kitchen, Christmas eve ish the boiler (only part of the old kitchen left) failed, so no heating over the break and silly quotes before a mate pointed me in the direction of a plumber who came out and kicked it back into life and then told me it was terminal and was likely to fail again which it eventually did.
We ended up moving the boiler soI had to re-do electrics and pipework and it was a nightmare winter with sporadic heating with the added cost of an all new boiler that I had not budgeted for. Christel went down with a heavy cold that took weeks to shake as well.
All I can say is bad luck about the boiler and I really hope the PCB resolves the issue because winter without a kitchen is bad enough, take the heating away and it is purgatory.
EDIT - I see she beat me to it on our epic boiler saga
