Martin Lewis has warned thousands of low-income households they could miss out on a £5,000 Green Homes Grant which will be scrapped this week.

The voucher scheme for people to upgrade their homes ends tomorrow and while current applications will be honoured, new applications must be completed by 5pm on Wednesday, March 31.

The scheme was launched to help low-income household save money on energy bills but will be scrapped after running for less than six months.

When it was first introduced, Martin Lewis explained how it works on his ITV show, The Martin Lewis Money Show.

He said: "It covers labour, materials and VAT. It is up to £5,000 of free money - you do not have to repay it - towards two thirds of the costs.

"Some benefits recipients can get up to £10,000 free to cover 100 per cent."

He added: "If you are in a new build, a house that you are not occupying yet, you cannot get this.

"The works must be completed in six months time and I think that will be difficult.

"This is only for England and there is nothing that replicates it really in Northern Ireland, Wales or Scotland."

The scheme has faced thousands of complaints with the rollout of the scheme described as “shambolic” by Greenpeace.

Greenpeace UK head of climate Kate Blagojevic said: "The green homes grant was the Government's flagship scheme to 'build back greener' but after a shambolic rollout it has officially now been scrapped.

"The biggest hole in England's energy efficiency is private households and you can't 'boost' the situation with a smaller pot of money.

"The Government is plain wrong to try and frame it as such."

Martin Lewis shared the frustration that the Green Homes Grant hadn’t gone to plan, describing it as a “shame”.

He tweeted: "#GreenHomeGrants which offer £5,000 homes improve grants is to be urgently closed (as predicted) to newbies.

"The govt flagship scheme is near useless; badly designed & poorly operated.

"Done right it could've provided jobs & healthier, greener homes.

"Shame!"

The government said: "The scheme was designed to provide a short-term economic boost while tackling our contribution to climate change.

“Applications made before the end of March deadline will be honoured and any vouchers already issued may be extended upon request."
