About UK Council Tax Cost & Band Index

CouncilTaxCost.co.uk is an independent civic research and property finance platform. We synthesize statutory local authority budgets, Ministry of Housing, Communities & Local Government (MHCLG/DLUHC) returns, Scottish Government 360ths multipliers, StatsWales revaluation schedules, and Valuation Office Agency (VOA) 1991 property valuation baselines across 2,977 UK postcode districts.

Lead Researcher & Editorial Director

Nguyen Hac Phong

Local Government Finance & Property Taxation Researcher

Nguyen Hac Phong leads the data architecture and policy research behind the UK Council Tax Cost & Band Index. With extensive expertise in statutory taxation frameworks, municipal billing mechanisms, and open demographic datasets, his work focuses on demystifying the UK's regressive local taxation structure and empowering householders with transparent, localized information.

Prior to establishing the 2026/2027 index, Nguyen analysed thousands of local authority budget statements, tracking adult social care precepts, police and crime commissioner (PCC) precepts, fire authority levies, and discretionary mayoral precepts. His analytical methodology directly links statutory parish and borough rates to individual postcode outcodes, bridging the gap between high-level municipal statistics and real household budgets.

Authority Consistency

Every outcode is mathematically locked to its billing authority district, eliminating random variance and reflecting genuine municipal precept totals.

Statutory Multipliers

Full national divergence support: England standard 9ths, Scottish post-2017 reformed 360ths, and Welsh 9-band (A–I) valuation schedules.

VOA 1991 Valuations

Statutory 1 April 1991 valuation baseline thresholds and neighbour band review procedures for challenging inaccurate property band allocations.

Statutory Data Sources & Methodology

Scottish Government & StatsWalesStatutory 360ths reformed ratios for Scottish local government and the 2003 Welsh revaluation bands (Bands A through I).

Official Statistics vs Modelled Estimates

All Local Authority Council Tax Band D baseline rates and statutory Band A–H/I ratios are derived directly from official government statistics (MHCLG Tables 1–9, Scottish Government local government finance statistics, and Welsh Government tax returns). Outcode-level band distributions, dominant bands, and typical bills are statistical modelled estimates reflecting regional housing stock profiles and are clearly labelled as such. They must not be treated as official Valuation Office Agency (VOA) records.
