Spark of 2026: #17 Testo Monitoring

Testo damp and mould monitoring kit

Sometimes you do not need a white paper to know something is going to land. You just need to watch what people actually buy.

I first saw Testo’s new damp and mould monitoring kit selling straight off the stand at a show. Not via a brochure or into an email campaign. Units leaving the stand.

Then I saw it again at the Installer Show. Same pattern. Engineers buying it there and then.

And over the months since, I have started spotting it on real work sites across the UK. Social housing teams. Maintenance contractors. Engineers who are tired of guessing and want something defensible, fast, and reportable.

If it's in their hands, there's not better proof.

This kit combines thermal imaging with humidity and surface condition measurement in a way that makes damp and mould visible, measurable, and documentable. It turns a vague problem into evidence. For landlords, councils, and contractors operating under increasing scrutiny around damp, mould, and preventative maintenance, that shift is critical.

The most telling signal is not the spec sheet. It is adoption. An at the time that Awaabs Law was brought into law, knowing the truth about how a building is performing isn't just good site work, it's critical

If engineers are paying for it with their own money, and organisations are rolling it out at scale, it means it is saving time, reducing risk, or closing arguments. Usually all three.

By the time a product moves from trade stand to installer vans to job sites nationwide, the decision has already been made by the market.

This one will be a hit in 2026.
