An indoor air quality survey measures how fresh and how damp the air in a building really is, over days rather than minutes. We place loggers that record CO2, humidity and temperature (and particulates in workplaces), then explain what the readings mean and what ventilation changes would help.
Powys has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

What indoor air quality surveys involves
CO2 is a practical indicator of whether a room is getting enough fresh air for the number of people in it: levels that climb steadily through a meeting or a night in a bedroom point to under-ventilation. Humidity readings show whether moisture is being removed or lingering long enough to cause condensation and mould. Surveys are useful before spending money: they show whether a problem is constant or happens at particular times, which rooms are worst, and whether an existing system is doing its job.
Before and after
Readings taken before and after a ventilation upgrade to show the difference.
Spot checks
Readings taken during a single visit, where a quick answer is enough.
Home survey
Loggers in bedrooms, living areas and wet rooms for 7 days, with a written summary.

Questions about indoor air quality surveys in Powys
Are prices different in Powys?
Our guide prices are adjusted by region. In Powys we use Wales rates, so home air quality check: CO2, humidity and temperature logged for 7 days is typically £140 to £235 inc VAT per home.
Do you measure particulates?
Workplace surveys include PM2.5 particulates; homes can have them added on request.
What is a good CO2 level indoors?
Outdoor air is around 400 to 450 parts per million; indoor levels that stay well below about 1,000 ppm usually indicate reasonable ventilation for the people in the room, while sustained levels much higher suggest it needs improving.
Is the survey free in Powys?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
Which rules apply to ventilation in Powys?
In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
