How to find comparable properties for your band challenge

Why comparables are the whole game

The VOA bands like with like, so the most persuasive thing you can show is similar homes near you in a lower band — the implication being that yours was banded inconsistently. Get the comparables right and the rest of the case follows.

What makes a property "comparable"

To the VOA's eye, a good comparable is the same kind of home as yours at the valuation date:

Same property type — house with house, flat with flat. A flat is never a comparable for a house.
Similar age / era — within roughly 20 years of build.
Similar size — floor area within about ±15%.
Same locality — ideally the same street; within ~250 metres is the rule of thumb.
No major difference — if it's much smaller, unextended, or a different class, leave it out.

Step 1 — list the bands around you (free, VOA site)

Look up your band and your neighbours' on the official checker at tax.service.gov.uk/check-council-tax-band. Walk your street and the next few streets and note every similar home's band. You're looking for predominance — most comparables a band below you, not just one or two outliers.

Step 2 — confirm they're genuinely similar (floor area)

Bands alone don't prove similarity. The free EPC register at find-energy-certificate.service.gov.uk lists floor area and room counts for most homes — check your candidates are within ~±15% of yours. A 70 m² flat is not a comparable for a 120 m² house even if it's next door.

Step 3 — pick the strongest 3–6

Quality beats quantity. A VOA caseworker dismisses a list "stacked" from a single road or padded with weak matches. Spread your picks across a couple of streets, and lead with single-band-lower homes — a one-band drop is far more credible than a three-band swing.

What to avoid

Different property types (the most common mistake).
Much larger or smaller homes.
Properties altered since the valuation date (an extension changes the comparison).
Cherry-picking the one low outlier while ignoring higher neighbours — the VOA sees the whole street, and it cuts both ways (see what if your band goes up).
