Our approach to planning

A useful planning aid should help you understand a decision, not leave you with an unexplained answer. The waste calculator applies these principles to pile measurements or an estimated loose volume.

Start with clear inputs

Questions should relate to the project you are planning and explain any unfamiliar terms. A person should be able to understand what information is being asked for and why it matters.

Show the assumptions

Guidance is only useful when its assumptions are visible. The basis for a recommendation should be explained so that you can decide whether it matches your circumstances.

Explain uncertainty

Projects rarely match a simplified description perfectly. Limits and uncertainty should be stated clearly, without presenting a planning estimate as a guarantee.

Planning estimate: SizeSolve provides sizing estimates based on the information you enter and conservative planning assumptions. Available bin or dumpster sizes, weight limits and accepted materials vary by provider. Confirm the final size, weight limits and material requirements with your local provider before booking.

Check the actual requirements

Your project’s conditions and any relevant requirements still need checking. Where a decision involves safety, suitability, or specialist judgment, seek advice from a qualified person who can assess the work.

The versioned planning policy uses the high estimate and explains uncertainty and safety gates. It supports conservative planning but cannot confirm a provider’s available sizes, weight limits or material requirements. Learn more about SizeSolve.
