EDF Energy has become the latest giant UK energy firm to suspend its doorstep selling programme.
It said it recognised that the "majority" of its customers didn't want to be cold-called at their home, or by phone, to be sold energy deals.
Many customers now prefer to go online to compare gas and electricity prices and find the best deal for them.
MPs had recently criticised "Del Boy" style doorstep sales, claiming the biggest energy firms were acting in their own interests, rather than those of their customers.
EDF employs 300 workers to carry out doorstep sales, and it said it was launching a 'consultation process' whilst reviewing its sales practices, according to the BBC.
EDF's residential director Jim Poole said: "Customers are increasingly looking for, and using, other ways to compare and choose their energy supplier. We recognise that face-to-face advice is important to some customers, and this will continue with sales at retail venues, and via appointment."
British Gas announced it was suspending its doorstep sales last month, calling the practice "outdated".
The moves come after MPs criticised the technique, after being told that 40% of those who had switched suppliers after a doorstep sale hadn't ended up with a better deal. They also questioned whether vulnerable people had been targeted.
Watchdog Consumer Focus has welcomed the announcement, saying customers were being put under pressure by doorstep salesman.
The Trading Standards Institute has also welcomed the suspension of doorstep sales. Chief executive Ron Gainsford told the BBC: "This is great news for consumers who for too long have been pressured and tricked in their own homes to make ill-informed and costly decisions about their energy provision.
"After of years of campaigning we are now finally seeing, one by one, the biggest energy companies abandoning doorstep sales in favour of better ways to reach their customers."
