A survey of 2,000 householders carried out by WaterSafe reveals two thirds (69%) put price before professional credentials when choosing a plumber.
However, 33% of respondents are subsequently charged much more than the original quote.
The research shows nearly a quarter (23%) of all consumers have fallen victim to a rogue plumber and a further 23% know somebody who’s employed a rogue.
The result is often major financial outlay – WaterSafe estimates Britain has shelled out £2.6bn rectifying poor plumbing jobs in recent years.
WaterSafe director Julie Spinks comments: “While it is understandable, following the recessional years, we have seen the advent of an increasingly savvy shopper – it is important to remember there are certain times when cutting costs can come at a price.
“When it comes to choosing a plumber, for example, by not ensuring they have the right qualifications and accreditation consumers run the risk of unwittingly choosing a rogue who may overcharge them and also carry out a poor job. In a worst-case scenario, this could end up costing them an absolute fortune to rectify and lead to major safety implications.”
