4.7 stars sounds excellent. In South West London, it's below average.

Figures in this article are a snapshot of the AIVIA Property Directory as it stood on 18 September 2026. The directory grows, so the numbers below will drift — they are reported as counted on the day, not as a permanent state of the market.

If you're choosing an estate agent in South West London, you'll probably look at the Google rating. Most people do. And most people will conclude that 4.7 stars is a strong score.

Here, it isn't. It's below the middle of the pack.

We pulled the numbers for every agency listed on this directory. On 18 September 2026 that was 200 agencies carrying a Google rating, with 43,520 reviews between them. Here's how they fell on the day:

Google ratings across 200 listed agencies, as at 18 September 2026

Google rating	Agencies	Share
4.9 – 5.0	94	47%
4.7 – 4.89	63	32%
4.5 – 4.69	22	11%
4.0 – 4.49	18	9%
Under 4.0	3	2%

Nearly half the agencies in South West London were rated 4.9 or better. On the day we counted, just three of the 200 sat below 4.0. The average was 4.76.

So the scale most people are reading is compressed almost entirely into its top half-star. A 4.5 looks respectable in isolation and sat in the bottom fifth locally. A 4.9 doesn't make an agency exceptional here — it makes it typical.

The bigger surprise: volume tells you almost nothing

The intuition is that a firm with a thousand reviews has earned its score, while one with forty got lucky. The numbers don't support it.

Mean rating by review volume, as at 18 September 2026

Review volume	Agencies	Mean rating
300+ reviews	42	4.78
Fewer than 100 reviews	69	4.75

Three hundredths of a star. The high-volume firms are not rated meaningfully better than the small ones. Volume tells you how long an agency has been collecting reviews and how hard it asks — not how well it works.

For context, on the same day the median agency had 161 reviews, and 24 had more than 500.

What this means if you're choosing an agent

The rating alone won't separate them. Once around five in six agencies sit above 4.5, the score has stopped doing the job you're asking of it.

What still discriminates:

• Read the two-star reviews, not the five-star ones. The pattern in the complaints is the signal — whether it's communication, fee surprises, or what happens after the offer is accepted.
• Check the recent ones. A 4.9 built over eight years can hide a bad eighteen months. Branch managers change and service changes with them.
• Look at what's being reviewed. Plenty of five-star reviews are from buyers who saw one flat. If you're selling, reviews from sellers are worth more than volume.

And if you run one of these agencies

You are, statistically, rated between 4.7 and 5.0 — along with almost everyone else in your patch. Your rating is not your differentiator, because your competitors have the same one.

Which raises a more useful question than "how do we get more reviews": what are the agencies winning instructions in your area actually doing that you aren't?

Method. Figures taken from the AIVIA Property Directory on 18 September 2026, covering the 200 listed agencies carrying a Google rating out of 202 listed in total. Ratings and review counts are as published by Google on that date and change continually. Averages are unweighted — each agency counts once regardless of review volume. As the directory adds agencies these figures will move; this article reports the position on the date shown rather than a fixed picture of the market.
