What Every School Leader Needs to Know – And How to Act Today
Today the Department for Education published its refreshed guidance on ventilation and air quality in schools and childcare settings.
This is the clearest, most practical advice yet – and it arrives at exactly the right moment. Poor indoor air quality is linked to higher pupil absences, reduced concentration and lower attainment. Good ventilation changes that.
Here’s what the guidance really means for you, the solutions that match your school type, the funding that is already available, and the simple steps you can take now to protect your pupils and make the most of your budgets.

The Guidance in Plain English – What School Leaders Must Know
Good ventilation is essential, not optional. It brings fresh air in, removes stale air, improves alertness, reduces the spread of colds, flu and other respiratory infections, and helps prevent overheating.
Key points for leaders:
- Prioritise fresh air through windows, doors and properly maintained mechanical systems.
- Use CO₂ monitors (NDIR type recommended) – one per typical classroom, placed at head height.
- < 800 ppm → Good ventilation (you can close windows in winter if needed).
- 800–1,500 ppm → Improve ventilation.
- > 1,500 ppm → Take urgent action.
- Keep mechanical systems serviced – clean or replace filters on schedule.
- HEPA air cleaning units are permitted only where you genuinely cannot achieve adequate fresh air in the short term, or in areas with high external pollution. They reduce airborne pathogens but do not count as ventilation and do not lower CO₂ levels. They must not be used as an excuse to keep windows closed or to delay proper ventilation improvements.
- Carry out a risk assessment, document your actions, and actively manage your buildings.
The message from DfE is supportive and realistic: you don’t have to overhaul everything overnight – but you do need to act on the data.

Practical Solutions Matched to Your School Type
A recent Airflow survey (February 2026) found that only 21% of UK schools have installed smart ventilation systems. The remaining 79% are the ones that will benefit most from today’s guidance.
| School Type | Biggest Challenges | Recommended Priority Actions (all DfE-compliant) | Expected Benefits |
| Primary/ Nursery | High pupil density, older buildings, window-only reliance | CO₂ monitors + staff training Quick natural ventilation routines Targeted mechanical extract HEPA only where CO₂ stays high | Fewer winter bugs, calmer classrooms, better concentration |
| Secondary/ Post- 16 | Larger spaces, higher occupancy, existing mechanical systems | Whole-site CO₂ mapping + smart controls MVHR upgrades Demand-controlled ventilation | Energy savings + improved exam performance |
| LA Maintained & VA | Smaller budgets but steady SCA/DFC funding | Network of CO₂ monitors + filter upgrades via frameworks | Easy compliance and low-cost wins |
| Academies & MATs | Access to CIF and larger estates | Full smart ventilation + heat-recovery systems as part of condition works | High return on capital funding |
| SEND/ Specialist | Noise sensitivity, medical needs | Quiet HEPA units + enhanced natural ventilation + acoustic design | Inclusive, low-disruption air quality |
DfE’s clear rule: Fix ventilation first. Use HEPA only as a temporary bridge or supplement.

Funding Routes That Are Open Right Now (February 2026)
You do not need a new central scheme – the money is already flowing.
| Funding Stream | Who Can Access | Status February 2026 | Ventilation Eligible? | Next Step |
| CIF 2025–26 | Academies, VA, sixth-form | £470m allocated to 656 schools – works happening now | Yes (heating/vent/overheating) | Check your outcome letter or the published list |
| SCA + Devolved Formula Capital | LA-maintained & larger MATs | Annual grants – spend this financial year | Yes | Add to next estates meeting |
| Renewal & Retrofit Programme | Selected schools (no bid) | Pilot launches April 2026 (£710m total to 2029–30). First 50 schools in East Midlands, Yorkshire & Humber, South East contacted directly | Yes – core focus | Watch your inbox from April |
| Facilities Supplies Framework | All settings | Live now | Yes – monitors, HEPA, full installs | Fastest compliant route |
| PSDS & local energy grants | Where decarbonisation applies | Projects running 2025–2028 | Yes (heat recovery) | Combine with ventilation works |

Why Acting Sooner (Not Later) Really Matters
| Timescale | What to Do | Why It Helps |
| Now – Easter 2026 | Order CO₂ monitors, run baseline audits, update risk assessment | Gives you solid data for funding bids and summer planning |
| April – July 2026 | Complete minor works and smart system installs | Ready for September return |
| Summer 2026 | Major mechanical or HEPA installations | No disruption to pupils |
| Before November 2026 | Full winter-ready plan in place | Avoid the usual spike in absences |
Act in the next 4–6 weeks and you will be ahead of the curve when the next funding conversations begin.
Your Simple 5-Step Action Plan
- Share today’s DfE guidance with your SLT and governors.
- Check your current CO₂ levels this week (it only takes minutes).
- Book a no-obligation ventilation walk-through with a trusted supplier.
- Identify which funding stream you can use.
- Build the works into your 2026–27 estate plan.
Pupils deserve to learn in fresh, healthy air. Today’s guidance gives you the perfect moment – and the clear route – to make it happen.
