Koziwarm were commissioned to attend my 80 yr old mother’s 7 year old vaillant combi boiler that failed.
They weren’t sure what component failed but suggested it may be one of 3 components. They could only diagnose through a process of elimination so ordered all three. Ultimately they decided all 3 failed on the same day and changed them all. This was about a week later. Parts bill: probe Koziwarm £65.28 Screwfix £28.85. Gas valve Koziwarm £272.20 Screwfix £171.99. PCB Koziwarm £337.41 Screwfix £213.99. All original vaillant parts including VAT. Labour was of course charged in addition! I live about 300 miles away from my elderly mother and therefore didn’t attend. After contacting Koziwarm with these facts I was informed their charges were reasonable and not inflated to take advantage of a vulnerable old lady. Absolutely shocking from a company she has been paying for an annual service from new.
