Indoor air quality surveys in Northumberland

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.

Our team is based in Great Barr, Birmingham, and we work throughout Northumberland, from Blyth, Cramlington, Ashington, Bedlington and Darras Hall. Visits for this work are charged, with the price agreed before we arrive.

How we do it

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.

Workplace survey

Before and after

Questions about indoor air quality surveys in Northumberland

Is the survey free in Northumberland?

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.

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.

Which rules apply to ventilation in Northumberland?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
