Looking for an Alternative to Off Mains Solutions?

If you're researching Off Mains Solutions and would also like to explore independent private-drainage specialists, Private Drainage UK can help you understand your requirements and find an appropriate specialist operating in your area.

Off Mains Solutions is a separate, independent company and is not affiliated with Private Drainage UK. This page exists to help people comparing options for private drainage guidance and specialist introductions — not to make claims about a competitor's service, pricing or quality, which we're not in a position to assess.

What Private Drainage UK does differently

Private Drainage UK is built as an independent information resource first — with in-depth guides on septic tanks, treatment plants, compliance and property transactions — and a specialist-matching service second. We don't employ drainage engineers ourselves; when you submit an enquiry, we introduce you to an independent specialist operating in your area. See how it works and how we make money for full transparency on the model.

Areas we cover

Our guide library covers septic tank and sewage treatment plant installation, replacement, repair, compliance, surveys and percolation testing, alongside dedicated guidance for buying and selling a property with private drainage. Start with our septic tanks or sewage treatment plants hub, or go straight to Get Help if you already know what you need.

Choosing between providers

When comparing any two private drainage information or specialist-matching services, it's worth checking: how the business makes money and whether that's disclosed, whether specialist introductions are exclusive or spread across many providers, and how independent the guidance content actually is. We set out our own approach on each of these openly across the site.
