Homeowners looking for landscapers on the TrustMark website notched up 57,000 viewings of contractors’ details in the first seven months of this year against fewer than 39,000 for the same period last year.
"With the economy in its current state many people do not have the money to move home or overhaul their house or garden," TrustMark spokesman Stuart Carter said.
"So they are doing more low-cost home improvements such as redesigning their gardens. Many still require a professional so we are advising consumers to be extra vigilant and only use reputable and legitimate people."
TrustMark, the Government-endorsed quality scheme that signposts people to reputable local tradesmen, is a registered social enterprise operated under licence from the Department for Business, Innovation and Skills.
Two months ago it launched a smartphone "talk to your tradesman" free app to help homeowners ask the right questions and hone their conversation skills with trades people before accepting a quote for work.
They can choose from one of the largest databases of on-site inspected licensed trades people in the country, with details of more than 21,000 licensed trades across all sectors.
