What early users found useful

"We were close to spending money on work in the wrong rooms. After a couple of weeks it was a lot clearer where the actual problem was, so we held off and changed course."

Housing officer, social housing provider

"The useful bit was being able to look at the before-and-after properly. One change clearly helped, another basically did nothing, which saved a fair bit of back-and-forth."

IAQ assessor, independent practice

"What helped was that it stopped us guessing. We could see the bedroom was the room to deal with first, instead of treating the whole house like the problem."
