Real scenarios — showing both good and bad results. This is what Quodar produces in under a minute.
The scenario
An 18th century farmhouse. Plumber quotes £12,000 to replace oil-fired central heating and gravity-fed hot water with a new boiler and unvented cylinder. 4 days including all materials. No further detail.
Situation
An 18th century farmhouse owner received a £12,000 quote from a plumber to replace the entire heating system. The quote was just two sentences with no specification detail.
What Quodar found
Missing OFTEC and G3 certifications (making the installation illegal), no boiler specification, no Building Regulations notification, no making-good allowance, and a price £3,000–10,000 below realistic market rate — suggesting hidden extras.
What happened next
The homeowner sent the draft letter Quodar provided. The plumber responded with a properly specified quote at £16,500. The original quote would likely have reached £20,000+ once extras emerged.
