Five other British tourists died. They are named as Raymond Eagle, 58, Christopher Davey, 51, Timothy Oakes, 57, Stephen Holding, 60, and Benjamin Ogden, 27.
The group arrived in Nepal on Wednesday and was due to begin trekking later on Friday.
They were travelling with Hampshire-based travel company Explore Worldwide.
Darren Kelly, a property developer and businessman, moved from Bolton several years ago to the Isle of Whithorn in Dumfries and Galloway. where he renovated property for holiday lets.
Prime Minister David Cameron offered his condolences to the families of the seven British tourists. He said: "It is an absolutely horrific incident and my thoughts go out to the families concerned.
We are doing everything we can to contact the next of kin and the British ambassador is very much on the case."
Managing director of Explore Worldwide Ashley Toft said: "We are devastated by this news. Our thoughts are very much with the families of those affected, both in the UK and in Nepal."
The Foreign and Commonwealth Office (FCO) said the families of the victims have all been informed.
Earlier this year, Vincent Kelly was part of a group of Bolton businessmen setting off on a 3,000-mile trip across the Atlantic in one of the world’s most extreme rowing challenges.
Vincent Kelly worked at Doric Developments and he was taking part in the 2013 Woodvale Atlantic Rowing Challenge to raise money for the Bolton Lads and Girls Club’s mentoring scheme.
Mr Toft said the plane belonged to Nepal's domestic airline Sita Air, which is approved by airline authorities, adding: "The weather was good. The plane was departing for Lukla and our passengers
were heading for Everest Base Camp at the start of their trek. We have no more information at present."
The twin-engine propeller Dornier plane crashed shortly after take-off at about 6.15am local time near Nepal's capital, Kathmandu. Five Chinese people and three passengers and four crew members
from the Himalayan country were also killed, with reports suggesting the accident was caused by a bird strike.
The British ambassador to Nepal, John Tucknott, told Sky News: "Regretfully all those on board perished. Our thoughts at the moment are with the families and friends of those who lost their lives."
Asked about the cause of the crash, Mr Tucknott said: "This is not the time to speculate, obviously there will be an air crash investigation and clearly we will have to wait to see what they find
caused the air crash."
The plane was heading east towards Lukla, the gateway to Mount Everest and a popular destination for trekkers, when it crashed near the Manohara River to the south west of the city. The pilot
reported trouble two minutes after take-off, and Tribhuvan International Airport official Ratish Chandra Suman said the plane appeared to have been trying to turn back to the airport.
The Foreign Office has set up a helpline for concerned relatives on 0207 008 1500.
