Indoor air quality surveys in Edinburgh

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.

Edinburgh 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 the work 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

Questions about indoor air quality surveys in Edinburgh

Are prices different in Edinburgh?

Our guide prices are adjusted by region. In Edinburgh we use Scotland rates, so home air quality check: CO2, humidity and temperature logged for 7 days is typically £140 to £235 inc VAT per home.

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.

What humidity should a home be?

Relative humidity of roughly 40 to 60 percent is comfortable for most homes. Readings that sit above 70 percent for long periods make condensation and mould much more likely.

Is the survey free in Edinburgh?

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 Edinburgh?

In Scotland, ventilation is covered by section 3 of the Building Standards Technical Handbooks. Private rented homes must meet the Repairing Standard, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
