Indoor air quality surveys in Hampshire

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.

Every job in Hampshire gets a written quote before it starts and a commissioning record when it finishes. We cover Winchester, Southampton, Portsmouth, Basingstoke and Gosport and the villages around them.

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

CO2, humidity, temperature and particulates in offices, classrooms or meeting rooms.

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.

Questions about indoor air quality surveys in Hampshire

Are prices different in Hampshire?

Our guide prices are adjusted by region. In Hampshire we use South East rates, so home air quality check: CO2, humidity and temperature logged for 7 days is typically £160 to £270 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 Hampshire?

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 Hampshire?

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.
