Some customers can change immediately. This is common where services are provided on an on-call or one-off basis, such as occasional septic tank emptying or emergency wet waste removal. Other customers may need to allow for a short notice period, most commonly around 30 days, depending on how their current service is set up.

What often causes uncertainty is exactly what steps to take. Many businesses are unsure whether they have a formal agreement in place, when it was last reviewed, or whether they are simply paying invoices on a rolling basis. This is especially common where services have been in place for several years without change.

First, identify which liquid waste services you actually need

Before looking at timeframes or notice periods, it helps to be clear about the type of liquid or wet waste service your site requires. Different setups allow for different levels of flexibility when changing provider.

You may be looking for liquid waste removal from a septic tank, cesspit, holding tank, or bio digester. You may need urgent on-call emptying when levels unexpectedly reach capacity, or you may prefer scheduled visits on specific dates each month. Some sites require a combination of both, particularly where multiple systems are in use.

Portable toilet emptying and cleaning is handled slightly differently, as this is usually provided as part of a long term hire arrangement rather than a standalone removal service. Understanding this distinction helps avoid confusion when reviewing your options.

How quickly can a change realistically happen?

Where liquid waste removal is provided on an on demand basis, switching supplier can often happen immediately. This includes one-off emptying, reactive servicing, or emergency requirements. We offer a bespoke service commitment to each and everyone of our valued clients.

For customers on a regular schedule, the most common notice period is around 30 days. This allows time for final collections, paperwork handover, and alignment of future visits. Longer notice periods can be arranged, particularly where agreements have been formally renewed.

If you are unsure, we’ll start with the most common questions. Do you remember signing or renewing a service agreement within the last 12 months? If not, there is a strong chance your service is operating on a non contractual rolling basis.

What does a liquid waste service agreement actually cover?

A commercial liquid waste service agreement is a practical document rather than a complex contract. It sets out exactly how human and industrial waste is removed, how often collections can take place, and how your compliance records are handled. Our family company operations ensure continuity in communication every time. We rigorously clean your unit, perform visual integrity checks and report back with any recommendations to consider. Our team has a keen eye to identify potential structural breaches and maintain an accurate log which is updated with every visit.

Some customers prefer fixed servicing dates each month to suit operational routines. Others require flexibility, with collections arranged when levels reach capacity. Many agreements are structured to allow a combination of scheduled visits and on-call support.

The purpose of an agreement is consistency and clarity. It ensures waste is removed safely, records are maintained correctly, and responsibilities are clearly understood by both parties.

Changing supplier without disruption

Changing liquid waste removal company does not need to cause disruption. A professional, licensed carrier will take the time to understand your existing setup, align with your current servicing schedule, and ensure all documentation is transferred correctly.

This includes confirming waste types, access arrangements, tank capacities, and any site-specific requirements. Where necessary, first visits can be planned to coincide with existing service dates, avoiding missed collections or overflows.

Local knowledge also plays an important role. A provider based nearby can often offer greater flexibility, faster response times, and reduced travel costs compared with long-distance call-outs.

Taking the next step

If you are considering a change, the next step is simply a conversation. Whether you need a one-off emptying, a regular scheduled service, or a flexible arrangement that combines both, discussing your requirements clearly will help establish how quickly a change can be made.
