The British Medical Association (BMA) is calling for GP appointments to be lengthened to 15 minutes, rather than ten.
The BMA's proposal comes following the Working Levels in General Practice report, which discusses measures to help the workload of GPs.
The report said the length of appointments does not give GPs enough time to treat patients with complicated needs, as they are normally allocated ten minutes, meaning some doctors see up to 60 patients a day.
BMA GPs' committee executive team member Brian Balmer called for consultation times "to increase to 15 minutes" with the Government providing on its promised funding to make this work.
He said: "General practice in the UK cannot be allowed to continue being run into the ground: it's time for positive change that gives patients the care they deserve."
An NHS England spokesman, however, revealed there is no limit on GP appointments and claimed there will be increased investment.
"How long to allocate to individual patient appointments is at the discretion of individual GP practices, based on patient need, and there are no national limits suggesting ten minutes should be the norm.
"GPs are under pressure, so the recently published General Practice Forward View is substantially increasing investment and reforming care to free up GPs to spend more time with patients."
