Quality you can trust.
Standards you can
verify.
Every claim DEW makes is independently verified. Every product is certified to an external standard. Transparency is not an option - it is how we operate.
Quality Control
Rigorous at
every stage.
DEW’s quality management system is certified to ISO 9001 – the international standard for quality management. This means our processes for specification, production, testing and release are formally documented, independently audited and continuously improved.
Every production batch is subject to in-process monitoring and end-of-line quality checks before release. Samples are retained from every batch to enable full traceability in the event of a query.
Our compliance framework covers not only product quality but claims substantiation. Every performance claim made on a DEW product label or marketing material is supported by test data. Nothing is asserted without evidence.
Product formulations are reviewed periodically against evolving safety standards and ingredient guidance. DEW does not wait for regulation to require a change – we act ahead of it.
Safety Principles
Three commitments.
No exceptions.
No harmful chemicals
DEW products are formulated without bleach, ammonia, phosphates, synthetic fragrances or any ingredient classified as hazardous under EU or UK REACH regulation. Full ingredient transparency is available on request.
Environmentally responsible
ISO 14001 certification covers our environmental management system – from energy use at the facility to waste management and packaging. Our concentrated refill system reduces plastic consumption and per-clean carbon footprint compared to conventional ready-to-use formats.
Skin and family safe
Allergy UK accreditation applies across the full DEW product range. Formulations are assessed for skin sensitisation, respiratory impact and cumulative household exposure. Safe for use around children, people with allergies and those with chemical sensitivities.
Certifications
Independently verified.
Our certifications are not marketing assets. They are the output of rigorous independent assessment – and they are renewed, not assumed.
Allergy UK
Independently assessed by Allergy UK as safe for use by people with allergies, asthma and chemical sensitivities. Applied across the full DEW product range.
ISO 9001 & 14001
Dual ISO certification, independently audited against internationally recognised standards for quality management and environmental performance. Both are formally documented, independently audited and renewed on an ongoing basis.
Good Manufacturing Practice
Our Dundee facility is GMP certified for the manufacture and supply of cleaning products. Every batch produced is subject to documented process controls covering hygiene, consistency and product safety.
Good Housekeeping Institute
Awarded the Good Housekeeping Institute’s “Getting Greener” endorsement in recognition of DEW’s carbon reduction and sustainability credentials. One of the most trusted consumer endorsements in the UK market.
Cruelty Free & Vegan
Developed without animal testing or animal-derived ingredients, supporting more responsible product choices while maintaining the same performance and quality standards across all ranges.
Made in Britain
All DEW products are manufactured at our facility in Dundee, Scotland. Full UK provenance from formulation through to finished goods.
Our commitment
The Safer Pledge.
The Safer Pledge is DEW’s public commitment to transparency, safe formulation and honest claims. Full ingredient disclosure. Evidence-backed performance claims. And a commitment to act on safety data before regulation requires it.
