Housebuilders — bonds and adoption desk

Sourced public data only (company results, FOI, List of Streets, NHBC). Figures are never invented. Compiled panels sit above The Treatment’s analytical pass.

Top 5 business-opportunity findings

Where a consultancy helping councils finish unadopted estates can focus first.

  1. Four-year average s.38 waits (up to 12) — HBF FOI shows structural backlog, not one-off snags. Opportunity: paid adoption programme management and snagging coordination for highway authorities. HBF source
  2. Highway bonds averaging ~£338k (up ~170% since 2018) — capital and surety tied up until adoption. Opportunity: bond-release workstreams and LA capacity support that unlock developer and surety capital. HBF source
  3. Suffolk alone lists 331 sites >3 years unadopted, naming Persimmon, Bloor, Bellway, Taylor Wimpey, Crest, Barratt/BDW, Vistry. Opportunity: builder-accounted pipelines and multi-site negotiation packs for one county. Suffolk FOI
  4. Barratt discloses £626.8m performance bonds/guarantees vs peers often unquantified. Opportunity: target majors with published surety exposure for structured adoption clear-down. Barratt AR
  5. Essex S36 lists tag 3,373 Private Road/Street rows across 12 district PDFs (plus a live DM s.38/s.278 portal and Newhall multi-builder adoption backlog). Opportunity: county-scale List-of-Streets triage and estate adoption programme support where builders are already named in public updates. Essex List of Streets

Market intel notes

  • Bond £m usually = broader performance bonds/guarantees, not NHBC-only.
  • Council metrics are not standardised — directional only. Never invent unadopted counts for pack-pending authorities.
  • Authority footprints (where shown): ONS Counties and Unitary Authorities (December 2025) BSC · Open Government Licence / OS.
  • Council brand logos omitted where no clear open licence was available — see logo citations.
  • Sources: profit · NHBC · panels · authorities
