Shameful company. Taking advantage of emergency call-outs. I explained my issue to the person on the phone. Called back to make sure they carry basic materials to fix common toilet issues. They require payment upfront. The plumber shows up without inlet valve, which is a basic material. Then they wanted to come back the next day and charge £200 to fix it, in addition to the £160 already charged, claiming it takes 3 hours to replace an inlet valve. So now I have been charged and my issue is not permanently fixed. Very unprofessional to show up without required materials. Plumber could have picked up parts at the shop, but didn't want to do that, it was only 5 minutes away.
