Buckingham Palace vs Loch Ness Water Reports: How to Check Your Water Quality by Postcode

🥊 Buckingham Palace vs Loch Ness Water Reports: How to Check Your Water Quality by Postcode

When customers ask us which shower filter would be best for them, one of the first things we ask for is their postcode.

Why?

Because we’ll go and check their local water quality report.

Once we see what’s actually in their water — hardness levels, chlorine levels, trace elements — we can recommend the shower filter that best matches their area.

The funny thing is… most people don’t even realise they can check their own UK water quality report online for free.

So instead of explaining it in a boring way, let’s make this interesting.

Welcome to the Water Quality Battle of 2026 🥊

In the red corner… 👑 Buckingham Palace

In the blue corner… 🐉 Loch Ness

Let’s see what the numbers say.

🥊 Round One: Water Hardness

When we check the published data for Buckingham Palace (SW1A 1AA) via Thames Water, we see a hardness level of:

260 ppm (2)

That firmly places central London in a hard water area.

Now let’s look at Loch Ness.

Scottish Water’s published hardness data shows:

8.77 ppm (1)

That’s extremely soft water.

Water hardness measures dissolved calcium and magnesium in the water.

As a general guide:

0–100 ppm = Soft
100–200 ppm = Moderately hard
200–300 ppm = Hard
300+ ppm = Very hard

At 260 ppm, London is clearly hard water.

At 8.77 ppm, Loch Ness has some of the softest tap water in the UK.

Round One? 🏆 Loch Ness wins on softness.

But don’t celebrate just yet…

🥊 Round Two: Chlorine Levels

Chlorine is added to UK tap water to keep it microbiologically safe.

When we look at the maximum recorded chlorine levels:

Loch Ness area: 1.21 mg/l (3)
Buckingham Palace area: 0.89 mg/l (4)

That means the maximum recorded chlorine level near Loch Ness was nearly 36% higher than central London.

Plot twist. 😮

Hard water in London.
Higher chlorine in the Highlands.

Both locations are now on the canvas.

🤔 What Does This Actually Tell Us?

Water quality isn’t one-dimensional.

You can’t judge it purely by location, reputation, or assumptions.

Hardness tells one story.
Chlorine tells another.

And your postcode will have its own unique combination of both.

That’s why checking your water quality by postcode matters.
