Food and drink on the high street
| Registered premises | Count |
|---|---|
| Restaurants and cafés (8.7 per 10,000 residents) | 1 |
| Takeaways and sandwich shops (8.7 per 10,000 residents) | 1 |

Counts are registered food premises in the Llanerchymedd built-up area (1,155 residents at the 2021 census), from the FSA food hygiene register, extracted 17 August 2026. The boundary is drawn from where the buildings are, so these figures cover the town itself rather than the wider council area, and no total is shown because the register also lists premises nobody would call a venue: school kitchens, care homes, warehouses.

Shops and services
| Premises | Count |
|---|---|
| Shops (all retail) (43.3 per 10,000 residents) | 5 |

Shops, cafés, salons, banks, post offices and arcades are rateable premises by use on the VOA 2023 rating list — the shops figure is all general retail, charity shops included. Gambling premises come from the Gambling Commission's licensing register, which lists 6,251 betting shops nationally against the rating list's 3,838: many betting shops are rated as ordinary shops, so the licensing register is the truer count and the one used here. Categories the rating list counts badly are deliberately absent rather than wrong: petrol stations disappear into supermarket ratings, vets and museums run far under their professional registers, and pools and nurseries mostly rate inside other premises.

| All recorded offences | 80.5 |
The all-offences line is a count of records, not a safety score: it weighs every category equally, which is exactly why we publish the categories. We deliberately do not combine them into a single index.
Figures are police-recorded crime (August 2025 to July 2026) located to this built-up area, per 1,000 residents at the 2021 census. Three cautions, each of which changes how a rate should be read: recorded crime is not crime experienced, because reporting rates differ by category and by place; the denominator counts residents, so town centres and visitor towns run high per resident precisely because many people there are not residents; and a high figure can reflect more reporting as easily as more crime. Percentiles compare towns of 10,000+ residents. Greater Manchester and Gloucestershire constabularies do not publish, so their towns show a note instead of a partial figure. Compare towns →
Schools
| Maintained schools in the built-up area | Count |
|---|---|
| Primary schools | 1 |
From the Welsh Government's address list of schools (April 2026), located to this built-up area by postcode. Maintained schools only. No capacity or fill figures are shown: Wales publishes no per-school capacity file beside the address list, and the English pages' fill rates come from exactly such a file, so a Welsh version would be a guess.
Broadband

| Gigabit-capable (1,000 Mbit/s+) | 40.2% |
| Superfast (30 Mbit/s+) | 98.3% |

Share of the 532 residential premises in this built-up area that the fixed network can serve at each speed, from Ofcom's Connected Nations coverage data (network state July 2025). Availability is what the line to a home can deliver if ordered, not what households actually subscribe to, and a full-fibre street where everyone bought the cheapest package shows 100% here.
