How to read a UK liveability score (and when not to trust one)

Every UK property site offers some flavour of area score now. Move iQ has a "living rating". Plumplot has a crime score. Crystal Roof has a "quality" index. Streetcheck cobbles together a council-tax- and-Ofsted-and-IMD blend. The numbers don't agree. Worse, almost none of them tell you the formula.

Our liveability score is published in full at /methodology/scoring/liveability. The formula is 0.30·safety + 0.25·transport + 0.20·schools + 0.15·rent_affordability + 0.10·EPC. Each input is itself a 0–100 score derived from named public datasets. You can disagree with the weights — they're editorial. This article explains why we picked them and where the score has known limits.

Why these five inputs

Every two years YouGov, Knight Frank and Savills run UK area-choice surveys asking renters and recent buyers what mattered most when they picked their current home. The same five categories surface every time, in roughly this order:

1. Crime / safety (mentioned by 70%+ of respondents in every survey)
2. Transport links (60–65%)
3. Cost / affordability (50–55%)
4. Schools — but ~70% of respondents have no school-age children
5. Energy / running costs (recently overtook schools for under-35s)

We weighted safety highest because it's consistently the top-cited factor across every demographic. Transport beats cost because cost is already partially baked into transport (a one-hour commute is itself a cost). Schools below transport because, again, most households don't have school-age children. EPC gets a 10% slot because energy bills meaningfully change the cost picture and used to be invisible to renters.

Where the score is strong

For comparing two roughly-similar UK neighbourhoods — a Brockley vs. Forest Hill, or a Didsbury vs. Chorlton — the score is genuinely useful. All five inputs are local-area truth or close to it, the weights aren't ridiculous, and the score is rebased to a national percentile after every refresh so a 70/100 always means "safer/better-connected/ better-schooled than 70% of England + Wales".

Where the score is weak

• Crime is per-resident, not per-visitor. A central nightlife area with 200 residents and a busy weekend strip looks unsafe because the denominator is wrong. We don't adjust for daytime/ nightlife population. A Soho vs. Hampstead comparison is mis-weighted in Hampstead's favour for this reason.
• The Greater Manchester crime gap is filled with a proxy. data.police.uk doesn't carry GMP data after mid-2020. The 1,294 affected areas are filled using the IMD crime sub-score from 2019. See the next article in this series for the full detail.
• Schools score reflects access, not admissions reality. We count Good/Outstanding schools within 2 km. We don't check catchment overlap, faith-school selectivity, or where last year's admissions cliff actually fell. For a household that needs a specific school place, the score is a starting point, not an answer.
• Rent affordability is council-area-level. Rent and salary both come from sources (ONS PIPR / ASHE) that publish at council level, not at the local-area level. So this 15% input is identical for every local area in the same council — it differentiates councils, not neighbourhoods.

Don't single-rank a place

Liveability is a starting point, not a verdict. The real value is in decomposing it: the area page shows the four component scores side-by- side so you can see whether a 65/100 came from high safety + low transport or from balanced everything. They feel very different to live in.

If you're comparing two areas, use /compare rather than eyeballing two single numbers. It surfaces the full set side-by-side with the winner subtly bolded — which is what the score is good for.
