10 Best Drain Unblockers 2025 in the UK

The Buster Bathroom Drain Unblocker is a liquid drain unblocker specifically formulated to tackle common bathroom drain issues like hair, soap scum, and sludge. It comes in a pack of two 300ml bottles, making it ideal for multiple uses. This product is effective: it begins working within 15 minutes, though leaving it overnight yields the best results.

It’s designed to address both full blockages and slow-draining water, making it versatile for use in showers, baths, and sinks. It’s also safe for septic systems, which enhances its compatibility with various plumbing setups. However, it's important to note that it is unscented, which may be a downside for users who prefer a product that leaves a fresh smell. The ease of use is commendable; the product is a 'one-shot' formula, meaning you simply pour it in and let it work, so there’s no need for manual intervention.

A notable strength of this unblocker is its compatibility with all types of pipes, ensuring that users can utilize it without worrying about potential damage to their plumbing systems. It's also designed to cut through standing water, which can simplify the process of clearing a clogged plughole. However, the product is unscented, which some users might find lacking, especially if they're looking for a fresher scent post-use.
