Estimates of the impact of the measures

The material before the court

279.

The evidence before the court as to the impact of the measures introduced by the LFRA 2024 came essentially from two sources:

i)

The exercise carried out in the IA and the Addendum IA.

ii)

Evidence adduced on behalf of the claimant groups as to the impact the LFRA 2024 has already had and will have on them.

280.

While neither side was able to agree with the other’s estimates, they both recognised that the LFRA 2024 would have a very significant beneficial effect on tenants, achieved through a very significant adverse financial effect on landlords.

281.

After these challenges had been issued, and when doing work to respond to FOIA requests from C&G, the Secretary of State identified a modelling error which had a significant impact on the IA modelling of the Ground Rent Cap. The Secretary of State published the Addendum IA, which addressed the consequences of that error, on 14 April 2025.

282.

We were provided with the following table in Agreed Statement F which summarised the financial effects of the LFRA 2024 as had been set out in the IA and Addendum IA in 2019 prices and at 2025 Present Value (save for the Net Benefit which was given in 2019 prices and at 2020 Present Value):

283.

The parties agree that the majority of marriage value is realised on enfranchisements in London (the IA estimating 65%, and the Addendum IA 66%, and Mr Roberts, C&G’s expert, estimating 69%). The parties did not regard these differences as significant for the purposes of the claims, and nor do we.
