For central government, ALBs and LAs
Impact assessments and options appraisals
GAIA drafts them in hours, to the standard in The Green Book, with your analysts steering every assumption.
Impact assessments end to end
From rationale and longlist through to the Appraisal Summary Table, to the standard applied by the Better Regulation Framework.
Ready for the 2026 Green Book refresh
The refreshed guidance expects appraisals to cover the Environmental Principles Policy Statement, the biodiversity duty, and the Public Sector Equality Duty. GAIA drafts each.
Submission deadlines don't move
Spending review returns, fiscal events and funding rounds can come out of nowhere. GAIA drafts the appraisal in hours, so the window goes on the assumptions rather than the document.
Your data stays where you expect
Processed only in the UK and EEA, or deployed internally on your own cloud.
In-house capacity
The guidance says build capacity in-house.
HM Treasury says public bodies should use external consultants only to fill capability gaps and should build capacity in-house, naming complex economic appraisals as its example. GAIA gives your own economists that capacity, on the appraisals you currently send out.
Green Book appraisal
The four steps of an appraisal.
GAIA follows the four steps of appraisal in The Green Book.
-
Rationale and objectives
Case for change, business as usual, and SMART objectives.
-
Generating options and longlist appraisal
Options assessed against critical success factors and narrowed to a shortlist.
-
Shortlist appraisal
Cost-benefit or cost-effectiveness analysis of each option, with optimism bias and sensitivities.
-
Identifying the preferred option
Best value for money, presented in an Appraisal Summary Table.
The same appraisal fills the strategic and economic cases if the proposal goes on to a business case.
