Guide · Decant Contingency Planning
Decant contingency planning, before the incident forces it.
The guide for housing associations and councils: what a credible decant contingency plan contains, how to test it, and where plans fail.
A decant contingency plan is the difference between an organised relocation and an expensive scramble. It pre-agrees the triggers, decision-makers, accommodation routes, suitability process, cost controls and resident communications for the day a building — or a works programme — forces residents out. This guide covers the eight components a credible plan needs.
- Housing associations
- Local authorities
- Building safety teams
- Emergency planners
The eight components of a credible plan
1 · Triggers and activation
Which events activate the plan — safety notices, structural findings, works overruns — and who has authority to activate it, including out of hours.
2 · Household data readiness
A maintainable register per block: household composition, accessibility needs, pets, school-age children, support requirements. Stale data is the most common failure.
3 · Accommodation capacity
Pre-contracted routes for hotels (first nights) and self-contained accommodation (works period), with realistic capacity assumptions per city.
4 · Suitability framework
How placements are matched and evidenced — accessibility, schooling, safeguarding — so decisions survive complaints and Ombudsman scrutiny.
5 · Cost control
Approval thresholds, weekly cost visibility, an extension protocol, and one consolidated invoice route instead of scattered supplier billing.
6 · Resident communications
Same-day instructions, a named contact for the duration, and pre-drafted letters for the first 72 hours.
7 · Procurement position
The compliant buying route agreed in advance — framework call-off or direct award with a documented urgency justification.
8 · Testing and review
An annual desktop exercise and a post-activation review that feeds real lessons back into the plan.
Where decant contingency plans fail
Plans fail at the edges, and almost always in the same places: household data that was accurate two years ago; an accommodation "arrangement" that was never contractual and evaporates on the night; no one authorised to spend money at 11pm; and communications that tell residents what is happening but not who to call tomorrow.
The test is simple: could a duty manager who has never read the plan activate it from the first page on a Friday evening? If not, it is a document, not a plan.
Writing the plan: a practical sequence
Map your stock risk
Which blocks could plausibly force a decant — remediation programmes, known structural risks, age and condition data.
Build the household register
Per-block data with a named owner and a refresh cycle. This is the plan’s foundation.
Contract the accommodation route
Pre-agree supplier, rates, activation route and reporting before you need them.
Agree governance
Activation authority, spend thresholds, extension approvals — in writing, with deputies.
Test it
Run the Friday-evening scenario. Fix what breaks. Repeat annually.

Frequently asked questions
What is a decant contingency plan?
A pre-agreed, tested plan describing how your organisation will relocate residents if a building or programme forces them out — who decides, which accommodation routes are pre-contracted, how suitability is assessed, how costs are approved and how residents are kept informed.
Who should own the plan?
A named senior owner — typically the head of housing, asset management or building safety — with operational deputies who can activate it out of hours. Plans owned by "the team" are activated by nobody.
How often should the plan be tested?
At least annually, and after every real activation. A desktop walkthrough of a realistic scenario — a block evacuated on a Friday evening — exposes most gaps: missing household data, no out-of-hours supplier route, no cost-approval path.
Does a plan need a pre-contracted accommodation supplier?
It is the single highest-value component. A supplier contracted before the incident means pre-agreed rates, a known activation route and no midnight procurement. Without one, the first 48 hours are spent buying instead of placing.
