Trethosa scores 61/100 overall, which the scorecard rates as good — 60 is typical for the country.
It stands out for safety (72) and transport (71).
Scores come from official data on safety, schools, transport, prices, health, food & drink and the local environment, for Trethosa in South West, each measured against the national average.
Trethosa is the kind of place you drive through rather than stop in unless you already live there — small terraces and a scatter of semis and detacheds, no shopfronts to speak of, the sort of village where the population barely fills a large primary school. Nobody moves here for buzz. They move here because Cornwall is home and this corner of it is quiet, affordable, and largely left alone.
That affordability is the real headline. Sales here have run around £178,000, against Cornwall's own median of £285,000 and a national figure closer to £281,000 — this is genuinely cheap ground, sitting low even against its county, and the terraced houses that dominate the local market (mostly freehold, no leasehold complications, no new-build estates) reflect a settled, older housing stock rather than a developer's afterthought. Set against an income decile of 3 and an IMD decile of 3, the picture is consistent: a working village that hasn't shared in the South West's more expensive corners, and a For Sale board here reads as "modest outlay, modest expectations" rather than aspiration.
The crime figures need a steady hand to read properly. Three incidents in the past year is a tiny number in absolute terms, but because the resident population is so small, the rate comes out far above the Cornwall average — the kind of statistical quirk that a village this size will always produce, where one bad month can swing the percentages wildly. Violence and sexual offences account for the largest single share of what's recorded, followed by theft and anti-social behaviour, but the raw counts are low enough that this reads as noise rather than a pattern of danger, and the safety grade itself holds at a solid, above-average level. Don't let the percentage delta against Cornwall spook you; look at the numbers underneath it.
Day-to-day, this is a place run on broadband rather than buses — full-fibre coverage sits above 60%, useful if your work or your evenings depend on a decent connection, and the connectivity and transport grades both come back strong, better than you'd expect for a village of this size. Green space is generously provided relative to population, more so than the regional average per head, which suits the median age here — early forties, slightly above the national norm, the profile of people who've settled rather than passing through. Schools rate reasonably rather than exceptionally, health provision comes back strong, and the overall grade sits comfortably above average nationally, nightlife aside (there isn't really any to speak of, unsurprising for a village this size).
Trethosa suits people who've made peace with quiet: retirees, established Cornish families, anyone priced out of the coast who wants low costs, decent connectivity, and space, and who won't miss having a high street on the doorstep. It won't suit anyone who needs bustle nearby or wants their property to do the heavy lifting on value — this is a place bought for living in, not for watching the market.
