Read the `policyengine` skill first for\nthe canonical `import policyengine as pe` interface, the population flow\n(`ensure_datasets` / `Simulation` / `economic_impact_analysis`), the MicroSeries discipline,\nand dataset handling — this skill only carries what is *different* about the UK.\n\nVerified against policyengine 4.21.0 + policyengine-uk 2.89.2 + policyengine-core 3.30.0\n(2026-07). UK examples are not in the `[us]`-only CI verify set, so they carry no\n`<!-- verify -->` marker; each was run manually in a `policyengine[uk]` environment.\n\n## Setup\n\nThe UK model is an extra — bare `policyengine` installs no country model:\n\n```bash\nuv pip install \"policyengine[uk]\"   # UK model + certified UK data bundle metadata\n```\n\nHousehold calculations need no data download. Population runs need the UK dataset, which is a\n**private** Hugging Face repo — see \"Population data\" below.\n\n## Entity model — and the benunit trap\n\nUK entities are **`person` → `benunit` → `household`**. There is **no `tax_unit`** and no\n`spm_unit` / `marital_unit` / `family` — those are US entities. The single most common UK\nmistake is reaching for `result.tax_unit` out of US habit; on a UK result it raises\n`AttributeError` (verified: a UK result has `person`, `benunit`, `household` and no `tax_unit`).\n\n| Concept | US entity | UK entity |\n|---|---|---|\n| Means-tested assessment unit | `tax_unit` (+ `spm_unit`) | **`benunit`** (benefit unit) |\n| Statistical unit for poverty | `spm_unit` / `household` | `household` |\n| Individual | `person` | `person` |\n\nA **benefit unit** is a single adult or a couple plus their dependent children — the DWP\nassessment unit for means-tested benefits (Universal Credit, Pension Credit, etc.). One\nhousehold can contain several benunits (e.g. adult children living with parents). Read\nmeans-tested benefits at the **benunit** level, income tax and NI at the **person** level, and\nnet income and poverty at the **household** level.\n\n## Household calculations\n\n`pe.uk.calculate_household` mirrors the US call (keyword-only, `year` defaults to 2026), but\nresults are read on UK entities. Access is dot-attribute on singular entities; only\n`result.person` is a list.\n\n```python\nimport policyengine as pe\n\nr = pe.uk.calculate_household(\n    people=[{\"age\": 35, \"employment_income\": 50_000}],\n    year=2026,\n)\nassert round(r.person[0].income_tax) == 7_486\nassert round(r.person[0].national_insurance) == 2_994\nassert round(r.household.hbai_household_net_income) == 39_520\n```\n\nNet income comes in two conventions: **`hbai_household_net_income`** follows the DWP\nHouseholds Below Average Income definition (the one PolicyEngine reports, and what the poverty\nmeasures below use); `household_net_income` is the plain accounting definition. Prefer the\nHBAI variable for anything compared against official UK statistics.\n\nBenefit-unit variables read off `benunit` (a family with two children on £30k gross):\n\n```python\nr = pe.uk.calculate_household(\n    people=[\n        {\"age\": 35, \"employment_income\": 30_000},\n        {\"age\": 33},\n        {\"age\": 8},\n        {\"age\": 5},\n    ],\n    household={\"region\": \"NORTH_WEST\"},\n    year=2026,\n)\nr.benunit.universal_credit   # 6029.82\nr.benunit.child_benefit      # 2337.40\n```\n\nReforms are the same **flat `{parameter_path: value}` dict** as the US package surface:\n\n```python\nreformed = pe.uk.calculate_household(\n    people=[{\"age\": 35, \"employment_income\": 50_000}],\n    year=2026,\n    reform={\"gov.hmrc.income_tax.allowances.personal_allowance.amount\": 15_000},\n)\nassert round(reformed.person[0].income_tax) == 7_000   # 2,430 more allowance x 20%\n```\n\n## Poverty — always state the measure\n\nUK poverty is reported at the **household** level under two measures, and they can disagree\nfor the same household:\n\n- **`in_poverty_bhc`** — Before Housing Costs.\n- **`in_poverty_ahc`** — After Housing Costs.\n\n```python\nfam = pe.uk.calculate_household(\n    people=[{\"age\": 35, \"employment_income\": 16_000}, {\"age\": 33}, {\"age\": 4}, {\"age\": 2}],\n    household={\"region\": \"WALES\"},\n    year=2026,\n)\nfam.household.in_poverty_bhc   # 1.0  (in poverty before housing costs)\nfam.household.in_poverty_ahc   # 0.0  (NOT in poverty after housing costs)\n```\n\nThat verified split — same household, BHC in poverty, AHC not — is why a UK poverty figure is\nmeaningless without its measure. Name BHC or AHC in every result, and match whichever the\nsource you compare against used (DWP HBAI headline child-poverty figures are AHC). Deep-poverty\nvariants (`in_deep_poverty_bhc` / `in_deep_poverty_ahc`) follow the same convention. At\npopulation scale these are the poverty variables behind `compute_uk_*` breakdowns and the\n`Poverty` outputs described in the `policyengine` skill.\n\n## Parameter lookup\n\nFor \"what is the rate/threshold?\" questions, read the parameter tree directly (no simulation).\nPrint the live value in your working year rather than trusting a hardcoded rate — UK rates and\nthresholds move at every fiscal event.\n\n```python\nfrom policyengine_uk import CountryTaxBenefitSystem\n\np = CountryTaxBenefitSystem().parameters\np.gov.hmrc.income_tax.allowances.personal_allowance.amount(\"2026-01-01\")   # 12570\n```\n\nBracket/scale parameters index the scale node with `[i]` (no `.brackets` in the reform-dict\npath, same convention as US):\n\n```python\n\"gov.hmrc.income_tax.rates.uk[0].rate\"   # basic-rate node in a reform dict\n```\n\nWhen browsing the tree object (not a reform path), a `ParameterScale` exposes `.brackets` as a\nPython list of `ParameterScaleBracket`, each with `.rate(date)` / `.threshold(date)`.\n\n## Devolved income tax — Scotland and Wales\n\nIncome tax rates live under `gov.hmrc.income_tax.rates`, whose children are\n`dividends, property, savings, savings_starter_rate, scotland, uk`. Verify band counts and\nvalues live (below is the verified 2026 structure, but treat the parameter tree as the source\nof truth — do not hardcode rates into analysis):\n\n- **Rest of UK (England & Northern Ireland):** `gov.hmrc.income_tax.rates.uk` is a\n  `ParameterScale`. Verified 4 brackets / **3 distinct statutory rates** — basic 20%, higher\n  40%, additional 45% (the 4th bracket is a technical top node repeating the additional rate).\n- **Scotland:** `gov.hmrc.income_tax.rates.scotland.rates` is a *separate* `ParameterScale`\n  with **6 bands** (verified 2026: starter, basic, intermediate, higher, advanced, top).\n  Scotland's extra bands are why a UK income-tax analysis must branch on nation rather than\n  assume the rest-of-UK schedule.\n- **Wales:** there is **no separate Welsh income-tax rate parameter** (the only `WALES`\n  parameter anywhere under `gov.hmrc` is in `business_rates`). The Welsh Rate of Income Tax is\n  set at parity, so Wales is computed on the rest-of-UK `rates.uk` schedule. Model Wales via\n  the `WALES` region, not a separate rate table.\n\n```python\np.gov.hmrc.income_tax.rates.uk.brackets              # verified len 4 (3 distinct rates)\np.gov.hmrc.income_tax.rates.scotland.rates.brackets  # verified len 6\n```\n\n## Regions (ITL1)\n\n`region` is a household-level enum. The `Region` enum\n(`policyengine_uk/variables/household/demographic/geography.py`) is the 12 ITL1 regions plus\n`UNKNOWN`:\n\n```\nNORTH_EAST, NORTH_WEST, YORKSHIRE, EAST_MIDLANDS, WEST_MIDLANDS, EAST_OF_ENGLAND,\nLONDON, SOUTH_EAST, SOUTH_WEST, WALES, SCOTLAND, NORTHERN_IRELAND   (+ UNKNOWN)\n```\n\nPass the enum member name as a string: `household={\"region\": \"SCOTLAND\"}`. `YORKSHIRE` is the\nkey for \"Yorkshire and the Humber\". UK constituency-level distributional analysis uses the\ndataset's `constituency_code_oa` column via `compute_uk_constituency_impacts` /\n`compute_uk_local_authority_impacts` — see the `policyengine` skill.\n\n## Population data\n\nThe UK default dataset is **`populace_uk_2023`** (a Microcosm build), pinned by the certified\nbundle in policyengine 4.21.0. It lives in a **private** Hugging Face repo, so population runs\nrequire a `HUGGING_FACE_TOKEN` with access:\n\n```bash\nexport HUGGING_FACE_TOKEN=hf_...   # required for UK population data; household calcs do NOT need it\n```\n\nDo not hardcode a raw `hf://` dataset URI — the certified default resolves by name through the\nbundle. The pre-Microcosm UK datasets are superseded. See the `policyengine-data` skill for how\nMicrocosm UK is built (FRS + WAS imputation) and calibrated, and the `policyengine` skill for the\n`ensure_datasets` / `Simulation` population flow, which is identical across countries.\n\n## Country-model development notes (policyengine_uk directly)\n\nEverything above uses the managed `pe.uk` surface. When you work *inside* the UK country model\n(new variables, structural reforms, debugging formulas), you use `policyengine_uk` directly, and\nthe reform surface there is the **`Scenario`** object, verified importable:\n\n```python\nfrom policyengine_uk.model_api import Scenario   # -> policyengine_uk.utils.scenario.Scenario\n```\n\n`Scenario` is a Pydantic model with two fields — `parameter_changes` (`{path: {period: value}}`)\nand `simulation_modifier` (a `Callable[[Simulation], None]`) — and scenarios compose with `+`\n(parameter dicts merge, modifiers chain). The country-package `Microsimulation(reform=...)`\naccepts **either a plain dict or a `Reform` class** (its verified signature is\n`reform: Union[Dict, Type[Reform]]`) and internally calls `Scenario.from_reform(reform)`.\n`Reform.from_dict(dict, country_id=\"uk\")` also works and applies correctly for both flat and\ndate-ranged dicts — there is no UK-specific `from_dict` failure. (Note: the UK baseline bakes in\nthe July-2025 Universal Credit reform, so a bare `Microsimulation()` is already post-July-2025\nUC law.)\n\nReform patterns for country-model work (from the analysis skill's\n`MICROSIMULATION_REFORM_GUIDE.md`):\n\nParameter-change scenario, with period syntax `\"year:START:COUNT\"` or an ISO date:\n\n```python\nreform = Scenario(parameter_changes={\n    \"gov.hmrc.income_tax.rates.uk[0].rate\": {\"year:2026:10\": 0.21},   # 21% for 2026..2035\n})\n```\n\nStructural or multi-year edits go through a `simulation_modifier`. The safe\n**parameter-freeze recipe** avoids corrupting shared parameter caches — clone, edit the clone,\nprocess, copy the `values_list` back, then reset caches:\n\n```python\ndef freeze_higher_threshold(sim):\n    clone = sim.clone()\n    clone.tax_benefit_system.reset_parameters()\n    node = clone.tax_benefit_system.parameters.gov.hmrc.income_tax.rates.uk[1].threshold\n    current = node(\"2026-01-01\")\n    for year in range(2026, 2031):\n        node.update(period=str(year), value=current, remove_after=True)\n    clone.tax_benefit_system.process_parameters()\n    sim.tax_benefit_system.parameters.gov.hmrc.income_tax.rates.uk[1].threshold.values_list = (\n        node.values_list\n    )\n    sim.tax_benefit_system.reset_parameter_caches()\n\nreform = Scenario(simulation_modifier=freeze_higher_threshold)\n```\n\nTwo gotchas from th","tagline":"Load before writing PolicyEngine-UK code — UK household calculations, income tax (incl.\nScottish and Welsh variations), National Insurance, Universal Credit and other benefits,\npoverty and reform analysis.
