What parts of my business should be covered in the ESOS energy audit?
From there, you must audit the areas that account for 95% of your overall energy. You’re allowed to class 5% of your energy consumption as ‘de minimis’ and exclude it from audits.
Your assessment should cover a representative sample of your operations and sites, and results should be presented in a common unit, such as pounds sterling or kilowatt-hours.
Are there penalties for ESOS non-compliance?
Failure to notify the Environment Agency can lead to an initial penalty of up to £5,000 and a daily fine of up to £500 until you comply – even if you’ve carried out your audits.
Making a false or misleading statement could lead to fees of up to £50,000.
When should my company begin its ESOS audit?
In previous phases, companies who put off their audit faced bottlenecks, delays, and a shortage of lead assessors, risking harsh non-compliance penalties.
Early ESOS reporting lets you lock in compliance, spread the cost of energy-saving initiatives, and realise their benefits sooner, rather than later.

Why does DSEAR matter?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require employers to control the risks from fire, explosions, and substances corrosive to metals.
If your site handles flammable gases, vapours, dusts, or chemicals, you’re legally required to assess and manage the risks of fire and explosion.
Failure to comply can result in:
DSEAR risk assessments
We conduct comprehensive site-wide evaluations to identify fire, explosion, and corrosion hazards associated with dangerous substances. Our assessments include:
- Identification of flammable gases, vapours, mists, and combustible dusts
- Evaluation of ignition sources and likelihood of explosive atmospheres
- Prioritised action plans to mitigate risks and ensure regulatory compliance
- Integration of process safety principles to reduce the likelihood of runaway reactions or decomposition events
- Support for near-miss investigations and process changes that trigger reassessment
How can we help?
We deliver a full suite of services tailored to your sector and risk profile to ensure you remain complaint with DSEAR regulations:
Polyurea delivers excellent waterproofing qualities, applied as a fast-setting plural component coating which has zero VOC’s and can be walked on within 10 seconds of application. Once cured, its properties include high tensile strength and elongation, supporting its adaptability in the event of deformation within the substrate in which it is applied.

Enforcement
HSE may issue notices (e.g., prohibition or improvement notices) requiring businesses to rectify issues identified during inspections.
Operational downtime
In extreme cases, non-compliance could lead to the temporary or permanent closure of business operations.
Explosion Protection Document (EPD)
We support the creation or review of your legally mandated EPD, ensuring it reflects current operations and hazards. Our service includes:
- •Detailed DSEAR risk assessments tailored to your processes
- Engineering controls and procedural safeguards aligned with best practice
- ATEX asset registers with traceable equipment specifications
- Hazardous Area Classification (HAC) drawings to EI15 and BS EN 60079-10 standards
- Competency matrices and training records to demonstrate staff capability
- Documentation of Basis of Safety for each process, including inerting, containment, or ventilation strategies
This document is essential for demonstrating compliance and protecting your workforce.
Hazardous area drawings
Our HAC drawings are developed in accordance with EI15 and BS EN 60079-10 standards, and include:
- Zoning of areas where explosive atmospheres may occur (Zones 0, 1, 2 for gases; Zones 20, 21, 22 for dusts)
- Identification of equipment suitable for each zone based on ATEX ratings
- Integration with site layout and process flow to support safe design and maintenance
- Recommendations for signage, labelling, and access control
These drawings are vital for safe system design and equipment selection.4. ATEX compliance checks
ATEX compliance checks
We offer scheduled inspections and full 3-year reviews of ATEX-rated equipment, covering:
