Need cleaning of distressed accommodation in UK

I'm looking for a reliable cleaner to tackle a neglected flat that has fallen into disrepair. The unit has heavy dust, mold in the bathroom, and some accumulated grime in the kitchen and living areas. I’d prefer a thorough deep clean with mold-safe products, proper sanitation, and attention to high-touch surfaces. Please bring your own cleaning supplies and equipment. Access is easy during weekday mornings, and I’d appreciate an on-site walk-through to confirm the scope before starting. This job is for a one-time deep clean, with the possibility of ongoing maintenance if the initial visit goes well.
