Building an Extension? Here’s How to Handle the Waste

Planning a home extension involves more than just bricks, drawings, and planning permission. One of the most overlooked aspects of any building project is waste management. From demolition materials to packaging and offcuts, extensions produce a surprising amount of waste that needs to be handled safely, legally, and efficiently.

This guide explains how to manage construction waste during your extension project — including skip hire options, waste types, and how to stay compliant with UK regulations.

Why Waste Management Matters During an Extension

Building an extension generates waste at every stage of the project — from groundworks and demolition through to interior finishing. Poor waste planning can lead to:

• Delays in work due to clutter or lack of space
• Extra costs for last-minute collections or tipping fees
• Safety hazards on-site
• Legal issues if waste isn’t handled correctly

Planning your waste disposal in advance keeps your site safe, your budget in control, and your project on schedule.

Common Waste Types During a Home Extension

Understanding the types of waste you’ll produce helps you plan the most suitable removal method.

Demolition Waste

• Bricks and rubble
• Concrete and hardcore
• Roofing materials
• Doors, windows, and frames

Construction Waste

• Timber offcuts
• Plasterboard and insulation
• Tiles and flooring
• Packaging (plastic wrap, pallets, cardboard)

Mixed Household or Garden Waste

• Garden soil and turf (from foundations)
• Old furniture or fixtures
• General rubbish during clear-out stages

Some materials, like timber and plasterboard, may be recyclable if kept separate — others, like rubble and soil, are classed as inert waste and need specialist handling.

Best Waste Disposal Options for Home Extensions

Skip Hire

For most extension projects, skip hire is the most practical and cost-effective solution. It allows you to store waste safely on-site and have it collected when full.

Benefits of skip hire for extensions:

• Handles bulk and heavy waste like rubble, concrete, and bricks
• Various skip sizes available for different project phases
• Saves trips to the tip and reduces disruption
• Helps keep the site organised and safe

Recommended skip sizes:

• 6 Yard Skip – Ideal for rubble, hardcore, and soil
• 8 Yard Skip – Great for general mixed building waste
• 12 Yard Skip – Suitable for light, bulky materials like wood or packaging

Avoid overfilling the skip or mixing restricted items — at Clearify, we’ll advise on the right type and help you stay compliant.

Grab Hire

If you’re removing a large amount of rubble or soil in a short time, grab lorry hire may be more efficient than a skip. A grab lorry can collect waste directly from the roadside using a hydraulic arm, ideal for hard-to-reach areas or if space is tight on-site.

Man and Van Waste Collection

For smaller loads or quick clear-outs (e.g. at the end of the project), a man and van rubbish collection is a flexible alternative. The team does the loading for you, and it works well for household items or light construction waste that doesn’t require a full skip.

Do You Need a Skip Permit?

If your skip will be placed on the road or public land, you’ll need a skip permit from your local council. Most permits take 3–5 working days and are valid for 7–14 days. At Clearify, we can arrange the permit for you as part of your booking.

You don’t need a permit if the skip is placed on private land like a driveway or garden.

Tips to Manage Waste More Efficiently

• Plan ahead: Arrange skip delivery for the start of demolition or groundworks
• Keep waste separated: Segregating wood, rubble, and general waste can reduce costs and improve recycling
• Don’t overfill: Skips must be filled level to the top edge (no overloading)
• Watch out for restricted items: Avoid placing asbestos, electricals, or hazardous waste in the skip
• Communicate with your builder: Make sure they know what waste goes where, and who’s responsible for disposal

What About Leftover or Reusable Materials?

Not all waste needs to be thrown away. Many leftover materials can be reused or recycled, including:

• Bricks and blocks
• Timber and joists
• Tiles, pavers, and surplus insulation
• Unused bags of cement or plaster

Consider offering usable leftovers to local reuse centres, community projects, or online through platforms like Freecycle or Facebook Marketplace.
