What happens next
BREEAM/LEED visits are scheduled to your handover programme.
We attend after cleaning and before occupancy, sample to the relevant published methodology, and issue a report your assessor can submit as evidence — re-testing promptly if any threshold is exceeded.
No unnecessary disruption. No generic paperwork. No unnecessary complexity.
Whether exposure is controlled
A clear yes or no, backed by measurement.
Where the highest risks are
Locations, tasks and roles ranked by exposure.
What actions matter most
A prioritised plan you can budget and schedule.
What you get
Four answers. One clear plan.
You need to know what your workforce is exposed to, whether your controls are effective, what actions matter most, and how to demonstrate control confidently.
That is exactly what we deliver.
Testing to the published protocol
Sample-point density, height and timing to the BREEAM Hea 02 and LEED EQc 4 methodology.
Laboratory analysis
Formaldehyde to MDHS 78 / NIOSH 2016, TVOC speciation by GC/MS to MDHS 96.
Evidence-pack reporting
Results, methodology and chain-of-custody formatted so your assessor can submit them as credit evidence.
Re-test where needed
Where a result exceeds the credit threshold, we advise on remediation and re-test promptly.
Why clients call
If any of this sounds familiar, you're in the right place.
- 01
An auditor is asking
HSE, your insurer or a client wants evidence — not assurances
We provide measured BREEAM / LEED IAQ data and a clear technical report that resolves the issue quickly.
- 02
Your team is worried
Operatives are reporting concerns or symptoms
We attend site, quantify workforce exposure and provide clear evidence of current risk levels.
- 03
You suspect a problem
You know there's a risk and you want measured data before it becomes a crisis
We quantify exposure, assess it against current limits and provide a prioritised corrective action plan.
What we answer for you
Three questions, settled.
- Where your people are exposed
- We map the tasks, areas and shifts where BREEAM / LEED IAQ matters, then sample what your team actually breathes — not a generic site average.
- Whether your controls are working
- An independent review of your LEV, ventilation, PPE and work practices — what is effective and what requires improvement.
- What you need to fix first
- A prioritised, costed action list — the smallest set of changes that gets you compliant and measurably safer.
How we work with you
From your first call to your action plan.
- 1
We listen first — your site, your concerns, your deadline.
- 2
We walk the workplace with your team to see exposure as it actually happens.
- 3
We sample on the people most at risk, using validated occupational hygiene methods for BREEAM / LEED IAQ.
- 4
We assess your existing controls honestly — what's working, what isn't.
- 5
You receive a clear technical report suitable for operational, compliance and regulatory readers.
- 6
We hand you a prioritised action plan you can budget, schedule and defend.

When the testing happens
After construction has finished, after final cleaning, before occupancy. Both BREEAM and LEED require sampling under conditions representative of normal operation, with mechanical ventilation running and finishes fully cured.
What we sample
BREEAM Hea 02 requires formaldehyde and TVOC; LEED EQc 4 requires formaldehyde, TVOC, particulate (PM10/PM2.5), CO and ozone. Sample-point density and locations follow the methodology published in the BREEAM and LEED technical manuals.
The thresholds you must meet
BREEAM: formaldehyde ≤ 100 µg/m³, TVOC ≤ 300 µg/m³ (post-2018 versions: see the current BREEAM technical manual). LEED: formaldehyde ≤ 27 ppb, TVOC ≤ 500 µg/m³, plus particulate, CO and ozone caps.
What happens if a result exceeds threshold
We help you isolate the source — typically a curing finish, sealant or adhesive — recommend remediation (extended ventilation purge, source removal, additional run-time), and re-test once the building is ready.

BREEAM and LEED Compliance — FAQs.
Quick answers to the questions we hear most from operations, HSE and procurement teams.
- When should we test?
- After completion of construction and cleaning, before occupancy, with HVAC running normally.
- How long does sampling take?
- Typically a single day for a small/medium building; larger or zoned buildings may need a 2–3 day visit.
- What if we fail?
- We diagnose the likely source, advise on purge and remediation, and re-test promptly.
- Do you cover both BREEAM and LEED in one visit?
- Yes — we routinely combine the protocols where a project is dual-certifying.
- Are your laboratories accredited?
- Analysis is carried out to UKAS-accredited methods at our subcontract laboratory. Sysco itself holds ISO 9001 certification, BOHS membership and AIHA PAT proficiency-testing participation.
- Can you support the assessor submission?
- Yes — we test and report; your licensed BREEAM Assessor or LEED reviewer submits and awards the credit. Our reports are formatted to drop straight into their evidence pack.
- Are you a BREEAM Assessor?
- No. Sysco is an independent testing provider. We carry out the pre-completion formaldehyde and TVOC measurement that supports the Hea 02 credit — the licensed assessor appointed to your project uses it as evidence.
