| Registered premises | Count |

Counts are registered food premises in the Therfield built-up area (310 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.

Schools
| Open establishments | Schools | Places | Pupils | Filled |
|---|---|---|---|---|
| Primary schools | 1 | 75 | 69 | 92.0% |
The 2021 census counted 21 children aged 5 to 9 in the town: one state primary school for every 21 of them.
Open schools registered in the Therfield built-up area, from the Department for Education's Get Information about Schools register, extracted 24 August 2026. Each school counts once: an independent special school appears under special schools, and the phase rows are state schools. Places are reported capacity and pupils each school's latest census return, summed only over schools reporting both, and shown only where at least 9 in 10 of a phase's schools do; state primaries across measured towns run at 89.2% of capacity, secondaries 91.3%. The children-per-school figure pairs a 2021 census count with today's register, so growth or decline since the census is not in it. No inspection grades are shown because Ofsted stopped issuing single-word overall judgements in 2024 and the register no longer carries them; current inspection reports are on Ofsted's own site. England only: the register lists Welsh schools without phase detail.
Broadband

| Gigabit-capable (1,000 Mbit/s+) | 0.0% |

Share of the 121 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.
