Questions answered

Frequently asked

What environmental compliance applies to the built environment?

The main UK duties cover water safety (Legionella under ACoP L8 and HSG274), discharges to sewer (trade effluent consent under the Water Industry Act 1991), environmental permits, energy and carbon reporting (SECR, ESOS), and building energy standards (MEES and EPC). The right set depends on your sector and assets.

Are these guides a substitute for legal or compliance advice?

No. They are accurate, sourced explainers to help you understand your duties and where you stand. They do not replace a competent assessment or formal legal advice, and your actual obligations depend on your specific sites and activities.

How do the free tools relate to these guides?

Each guide links to a free tool that turns the duty into your own numbers: a water safety risk scorecard for Legionella, a trade effluent bill estimator, and a cooling tower water and cost calculator. The guide explains the rule; the tool sizes it for your site.
