A "No system present: electric heaters assumed" lodging carries SAP Table 4a code 699 (electric room heaters) but RdSAP main_heating_category 1, NOT 10. `_table_12a_system_for_main` keyed the direct-acting-electric routing on category==10 only, so the category-1 form fell through to None and `_space_heating_fuel_cost_gbp_per_kwh` billed space heating 100% at the off-peak LOW rate — as if direct-acting room heaters charged overnight like storage. Per RdSAP 10 §12 Rule 3 (PDF p.62) electric room heaters (691-694, 699) route to the 10-hour tariff, and SAP 10.2 Table 12a Grid 1 (PDF p.191) gives the "other direct-acting electric" row a 0.50 high-rate fraction at 10-hour (1.00 at 7-hour). Route those SAP codes — the same set §12 Rule 3 already uses — to OTHER_DIRECT_ACTING_ELECTRIC alongside the category-10 gate. Found via the PE/CO2-vs-cost split on the worst over-rater in the /tmp sample: cert 2958 PE +0% / CO2 -1% (energy correct) but SAP +32.2 — a pure cost-side bug. Space rate 7.50 -> 11.09 p/kWh; cert 2958 +32.2 -> +14.7. The committed corpus gauge is unchanged (its 3 non-category-10 code-699 certs are all on Single meters -> STANDARD tariff, so this split never applies to them); the win is on the unbiased /tmp population's single worst cert.
