Berthlwyd, Pentwyn scores 48/100 overall, which the scorecard rates as fair — 60 is typical for the country.
No topic reaches "very good" (70+); its best is environment (68).
It scores lowest on schools (28).
Scores come from official data on safety, schools, transport, prices, health, food & drink and the local environment, for Berthlwyd, Pentwyn in Wales, each measured against the national average.
Berthlwyd sits on the northern edge of Pentwyn, one of those pockets of Merthyr Tydfil where the terraces and semis give way to hillside, and the pace is set more by the landscape than by any high street. There's no dense run of shops here — this is a residential fold of the valley, the kind of place you notice for its quiet rather than its bustle, and it attracts people who want a house near the hills without leaving the county they grew up in.
Beyond that, the detail thins out. There's no local pricing, crime, or school data logged for Berthlwyd itself, which makes it hard to say with any confidence how it compares to the wider Pentwyn area or to Merthyr Tydfil as a whole. What we do know is the county context: Merthyr Tydfil's typical house price sits well below the Welsh average of around £208,000, so anyone househunting in this corner of the valleys is likely working with a gentler budget than in most of the country.
Given how little is pinned down at the local level, it's worth treating Berthlwyd as an extension of Pentwyn and Merthyr Tydfil more broadly rather than a distinct entity with its own pulse — and doing your own groundwork on the street level before deciding whether it fits.
