As far as I have read the government is helping.
They have said that the builders who took shortcuts to save on building costs should fund the remediation work should be those who pay for it.
Some very large firms have already agreed, and put forward budgets to do the work.
The work of remediation has started in many places, but will not be a 'quick-fix'

Industry to pay

Builders agree to pay
"Under the new agreement, which will become legally enforceable, over 35 of the UK’s biggest homebuilders have pledged to fix all buildings 11 metres+ that they have played a role in developing in the last 30 years.

For the companies yet to make the pledge, the Secretary of State has also confirmed there is little time left for them to sign up, and that those who continue to refuse will face consequences if they fail to do so.

As set out in January, a new government scheme will also see industry pay to fix buildings where those responsible cannot be identified or forced to in law. This follows previous confirmation that plans for a 30-year loan scheme paid for by leaseholders would be scrapped."
