## Methodology

Full-fibre take-up as a share of the premises the fibre already passes, per borough — the gap between infrastructure built and infrastructure bought. A borough can rank high here while ranking low on availability, and Tower Hamlets manages both at once. From Ofcom's Connected Nations Spring 2026 update, retrieved via the Internet Archive because Ofcom's CDN refuses automated clients; the figures are Ofcom's own.

## Visualisations

- [Map](https://londongraph.com/g/built-but-not-bought): Compare the same measure geographically.
- [Overview](https://londongraph.com/g/built-but-not-bought?view=overview): The fibre is there. In most of London, most people haven't taken it.
- [Distribution](https://londongraph.com/g/built-but-not-bought?view=distribution): Place every mapped area in the selected measure's distribution while preserving missing values.
- [Availability vs take-up](https://londongraph.com/g/built-but-not-bought?view=relationship): Show where full fibre has been built and where premises subscribe. Caveat: A spatial association does not establish that either measure causes the other.
