The fundraising website has trousered 5 percent of the £4million given by well-wishers to help survivors and victims’ relatives and has rejected calls to waive its commission which it insists pays for the running and monitoring of its web pages.
Labour MP John Spellar said: “I understand that they need to cover their costs.
“But they should also recognise that making a significant profit isn’t why people give their money to charity and they should see sense and cough up.”
The JustGiving website lets people raise money at the click of a button but the company takes a 5 per cent cut from every donation and charges charities a monthly subscription of up to £39.
The site justifies the fee by saying it helps “people raise more money, more efficiently”.
Grenfell Tower was engulfed in flames one year ago today after a small kitchen rapidly spread through the high-rise block in north Kensington, west London.
The most deadly domestic blaze since the Second World War claimed 72 lives an affected hundreds more.
Figures show that 68 families will spend the anniversary in emergency accommodation, mainly hotels.
Kensington and Chelsea Council said 52 households are still in temporary accommodation and 83 families are now in permanent homes.
A series of events are taking place to mark the anniversary of the devastating blaze.
Grenfell Tower and 12 surrounding blocks were lit up in green in a show of solidarity across the west London skyline and Downing Street was also to be illuminated.
The buildings were lit up from 00.54am – the time off the first 999 call reporting the fire – until 5am.
For the following four evenings they will be illuminated from 8pm until midnight.
The display is one of a series of commemorations and vigils taking place this week as the public inquiry takes a step back.
On the eve of the anniversary, members of the grieving north Kensington community gathered for a 24-hour vigil to reflect on those who died in the fire.
During the private vigil at St Clement’s church, the names of the 72 victims will be read out at 1.30am.
From 11am, there will be a service of remembrance at St Helen’s church organised by campaign group Relative Justice Humanity for Grenfell.
Clarrie Mendy, who lost two family members in the fire and organised the anniversary event, said the names of the 72 victims would be read out, while 73 doves will be released outside the church.
She said: “It’s a service of healing, community, inclusivity and solidarity, to know we are not alone.
“We’ll be releasing 73 white doves. Why 73 instead of 72? One for the unknown. If there were more than 72, we will put one for the unknown.”
They will be giving out 400 white roses which people will able to carry on their way to the tower afterwards.
In addition, a moment of silence will be observed at midday by survivors and bereaved gathered close to the tower’s base and nationally.
A community mosaic is to be unveiled, while wreaths will be laid and candles lit.
The tower is now completely covered by white sheeting, with banners featuring the green Grenfell heart and the words “Grenfell forever in our hearts” emblazoned across the four highest floors.
In the afternoon, the community is expected to congregate at the nearby “Wall of Truth” ahead of the silent march which will set off around 7pm.
Labour leader Jeremy Corbyn will join survivors, the bereaved and others at the dignified gathering, which has taken place every month since the fire.
