In the article below DASH Services hears from Andrew Fitzpatrick from ArcAirTech on what services they can offer Landlords ahead of the new legislation that is due to come into force in the Private rented sector. 

The upcoming Renters’ Rights Bill brings major changes for private landlords. A key element is the introduction of the Decent Homes Standard (DHS), aligned with measures already in place for social housing.

Under this, Awaab’s Law will apply to the private rental sector. This means landlords must meet strict requirements on timescales for dealing with hazards such as damp and mould.

Penalties for non-compliance are severe:

• Minor or initial breaches: civil penalties of up to £7,000
• Serious, persistent, or repeat breaches: civil penalties of up to £40,000, or even criminal prosecution

With enforcement ramping up, damp and mould are no longer just tenant complaints — they’re a serious compliance and financial risk.

Why mould matters

Mould isn’t just unsightly — it’s a recognised category 1 hazard under the Housing Health and Safety Rating System (HHSRS). Left unchecked, it damages property, lowers EPC performance, and risks tenant health. Traditional methods of treatment often fail to tackle the root cause, leading to recurring issues.

That’s where our innovative technology comes in.

A Proven Full-Home Solution

At ArcAirTech, our patented technology has been proven to eliminate up to 99.9% of mould spores and contaminants. Here’s how it works:

• ARC Cell Technology – Our system generates hydroxyl radicals using UV-C light and a specially engineered quad-metallic catalyst. These hydroxyls are active cleaning agents that neutralise mould at a molecular level.
• Whole-Home Reach – Unlike other methods that only act at the source, hydroxyls travel through the property, tackling both air and surfaces — covering up to 1,500 square feet.
• Moisture Harnessing – Our process temporarily binds water molecules, reducing condensation, damp, and stagnant moisture build-up, while promoting airflow and ventilation. As our systems are designed to run constantly, water molecules are continuously recycled and bonded.
• Preventing Regeneration – By breaking mould down into harmless base elements, our systems disrupt spore regeneration and help prevent mould from reoccurring.

In practice, this means a true long-term solution for landlords dealing with persistent mould issues.

Case Example:

One of our clients faced ongoing issues in a block of flats where mould problems reappeared every 3–4 months. Despite repeated mould washes and remediation, the problem kept returning, creating recurring costs, tenant disruption and ongoing maintenance pressures. Since installing our Fixed ARC over a year ago, they have had no reports of mould in any of the properties. The Fixed ARC has eliminated the cycle of repeat callouts and remedial works whilst delivering safe homes for their Tenants.
