Indoor air quality surveys in Cheshire

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.

We carry out indoor air quality surveys across Cheshire, including Chester, Crewe, Ellesmere Port Town, Widnes and Runcorn. Prices use North West rates. This is a charged visit. We confirm the cost in writing before we book it.

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.

Home survey

Loggers in bedrooms, living areas and wet rooms for 7 days, with a written summary.

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.

Questions about indoor air quality surveys in Cheshire

Is the survey free in Cheshire?

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.

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.

How much does an air quality survey cost?

A home survey costs £145 to £245 including VAT, and a workplace survey £495 to £1,195 excluding VAT, depending on the number of rooms.

Which rules apply to ventilation in Cheshire?

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.
