What is the DEFRA Digital Waste Tracking mandate?

The Digital Waste Tracking (DWT) mandate is a law under the Environment Act 2021 requiring all waste receiving sites in England to record waste movements digitally from 1 October 2026. Paper waste transfer notes, spreadsheets, and email chains will no longer be sufficient. Producers and carriers who fail to submit digital records face Environment Agency enforcement action, including fines and prosecution.

What is BREEAM Wst01 and how does WasteMapper help?

BREEAM Wst01 is the construction waste management credit in BREEAM UK New Construction - the UK's leading sustainability rating system for buildings. It requires a minimum 95% waste diversion rate by weight, a pre-construction Site Waste Management Plan, and a complete digital movement register with EWC codes, carrier licence details, and disposal routes for every collection. WasteMapper generates the exact evidence pack format BREEAM assessors expect in one click - covering a process that typically takes contractors two days to compile manually.

What happens if my construction business isn't DWT-compliant by October 2026?

From 1 October 2026, waste receiving sites that fail to record movements digitally face Environment Agency enforcement. The EA fined over £8.5 million across the construction sector in 2025 alone. Non-compliance also creates duty of care liability - if waste is mis-described or ends up fly-tipped, the producer bears responsibility without proper digital records to prove due diligence.

How does WasteMapper verify waste carrier licences?

Every time a waste movement is logged, WasteMapper checks the carrier's licence number live against the Environment Agency's public register in real time. If a carrier's registration is expired, suspended, or invalid, the system flags it immediately - before the vehicle leaves site. This verification is recorded permanently on every movement record, providing your duty of care evidence.

Who is WasteMapper built for?

WasteMapper is designed for SME construction contractors and developers who need waste compliance without a dedicated environmental manager. If waste management currently falls to a site manager, a quantity surveyor, or "whoever deals with it," WasteMapper is built for you. It works across house-builders, groundworks contractors, fit-out specialists, and main contractors on BREEAM-rated projects.

How quickly can site workers start logging waste?

Site workers can start logging in under 60 seconds with no app download and no login required. They scan a QR code placed on site, select the waste type, photograph the collection, and submit. GPS, timestamp, employee ID, and carrier details are captured automatically. Setup for a new project typically takes under 5 minutes.

Is WasteMapper free to try?

Yes. WasteMapper has a free plan that supports 1 project and 50 waste movements per month - no credit card required. Paid plans start at £49/month for single-site contractors (Site plan). The Pro plan at £199/month covers up to 10 projects with multi-site dashboards, ESG reporting, and compliance alerts.

Does WasteMapper integrate with the GOV.UK Digital Waste Tracking service?

Yes. WasteMapper creates digital waste records that are compatible with DEFRA's DWT reporting requirements. The Intelligence plan (£499/month) includes full DEFRA API integration for automated submission - removing the need for manual data exports as the October 2026 deadline approaches.
