An Awaab's Law response. Built to grow with the law.
MouldWatch exists to help landlords meet a legal duty - and prove it. The law starts with damp and mould, so we do too: see the risk weeks early, respond inside the statutory windows, fix the real cause, and keep the record that shows it. As Awaab's Law widens through Phase 2 and 3, MouldWatch is built to widen with it.
MouldWatch launches with a contracted programme of more than 3,000 homes across four housing associations in England and Wales, beginning with 724 homes in Kent. Built for Awaab's Law in England and the WHQS hazards rule in Wales.
One response, three specialists.
Spotting risk early, investigating and fixing homes, and certifying the people who do the work are three different jobs. MouldWatch puts them under one contract, so there is one record to show a regulator what happened.
Tether
Tether (TetherHQ Limited) is a healthy-building sensor and software company, with technology in use across offices, factories, shops, and homes. Its sensors and mould-risk model - fine-tuned for the way British homes are built - are what see a problem coming weeks early, and its platform is where every reading, alert, and action becomes one property record.
Quidos Group
Quidos Group is a UK compliance and building-safety specialist. As a government-approved energy-assessment accreditation scheme, it understands what sits underneath damp and mould: why homes lose heat, why some cost so much to keep warm, and how a cold, hard-to-heat home slides into condensation and poor health.
Quidos Protect
Quidos Protect is the response arm: a national platform for emergency response, facilities management and remediation that already handles more than 80,000 calls and visits a year through its 24/7/365 operations centre in Cardiff, including home-emergency response for national insurance companies. For MouldWatch it brings a network of qualified surveyors and remediation teams across England and Wales, trained and certified in damp and mould work from triage through to sign-off.

Damp and mould is where the law starts, and more hazards join in 2026 and 2027.
Awaab's Law arrives in phases, and each phase brings more hazard classes under the same statutory clocks. We built MouldWatch so that when a new hazard class comes in, it goes onto the property record you already have and is handled by the same field teams.
Excess cold is where the partnership fits best. Tether reads the conditions inside a home, Quidos knows its energy performance, and together they can pick out a cold, hard-to-heat home before it slides into damp. Quidos Protect already delivers heating and retrofit work, and will service the Welsh Government's Optimised Retrofit Programme.
Damp and mould, plus emergency hazards. The statutory clocks are already running, and this is where MouldWatch starts.
Excess cold and heat, falls, structural collapse, fire, electrical hazards, and hygiene hazards join the same clocks.
The remaining HHSRS hazards, except overcrowding.
The map is wider than England, too: Wales runs its own hazard clocks under the WHQS, Scotland's duties commence in October 2026, and the private rented sector follows under the Renters' Rights Act. The full horizon lives on the roadmap.
Awaab Ishak.
Awaab Ishak was a two-year-old who died on 21 December 2020 of a severe respiratory condition caused by prolonged exposure to mould in his family's flat in Rochdale, managed by Rochdale Boroughwide Housing. The coroner's inquest concluded in November 2022. Within weeks, the Regulator of Social Housing issued a regulatory notice against the landlord; within three months, government had announced the law that now bears his name.
Every case we take on will be a small contribution to what this law is for: children in homes that are safe to live in.
See how it would work for your homes.
We work with social landlords in England under Awaab's Law and in Wales under the WHQS, and with private landlords getting ready for the law to reach them.
