A loft conversion is one of the most popular home improvement projects in the UK — and for good reason. It adds space, boosts property value, and often doesn’t require planning permission. But one part that’s often overlooked is the waste disposal.
From timber offcuts and insulation to old roof tiles and plasterboard, loft conversions create a surprising amount of waste. In most cases, hiring a skip is the easiest, most efficient way to keep your project tidy and on track.
This guide covers everything you need to know about skip hire for a loft conversion — including what size you need, what can go in it, and how to avoid common pitfalls.
1. How Much Waste Does a Loft Conversion Produce?
Every loft conversion is different, but even a small project can generate several tonnes of waste.
You’re likely to produce:
- Old roofing materials (tiles, felt, battens)
- Timber joists and flooring
- Plasterboard and insulation
- Bricks and rubble from dormer or chimney removal
- General building debris and packaging
Depending on the size of your conversion and how much structural work is involved, you may need multiple skips or a single, well-sized one that’s collected and replaced mid-project.
2. What Skip Size Do You Need for a Loft Conversion?
Here’s a general guide to help you choose the right skip size:
| Skip Size | Approx Capacity | Best For |
|---|---|---|
| 4 Yard Skip | ~30–40 bin bags | Light building waste or smaller projects |
| 6 Yard Skip | ~50–60 bin bags | Timber, plasterboard, light demolition |
| 8 Yard Skip | ~60–80 bin bags | Ideal for most loft conversions (if not overloaded) |
| 12 Yard Skip | ~100+ bin bags | Bulky, lightweight waste only (not soil or bricks) |
Important: Loft conversions often involve heavy materials like bricks or rubble. Avoid hiring skips larger than 8 yards for this type of waste, as they may exceed legal weight limits when full.
If you’re unsure, Clearify can recommend the right skip based on your plans and schedule.
3. What Can Go in the Skip?
For a loft conversion, you’ll typically be disposing of mixed construction waste, which may include:
- Timber and wood offcuts
- Plasterboard and insulation
- Roofing felt and tiles
- Bricks, hardcore, and rubble
- Old floorboards or ceilings
- Builders’ waste, packaging, and dust sheets
Items you can’t put in a general builders’ skip include:
- Asbestos (commonly found in old insulation or ceilings)
- Paint, solvents, and adhesives
- Gas bottles or pressurised containers
- Electrical items (e.g. light fittings, sockets)
If your conversion involves stripping out an old water tank or electrics, speak to your provider to arrange proper disposal for restricted items.
4. Do You Need a Permit?
If the skip will be placed on a public road — rather than your driveway or front garden — you’ll need a skip hire permit from your local council.
What to know:
- Permits usually last 7–14 days
- They cost between £15–£70 depending on your location
- Most skip hire companies (including Clearify) can handle the permit application for you
If space is tight or access is tricky, ask about alternative options like wait-and-load services, which don’t require a permit.
5. Plan Your Waste Around Your Project Timeline
A loft conversion typically happens in stages — from structural work and insulation to final fix and plastering. This means waste is generated throughout the project, not just at the beginning.
Tips:
- Schedule your skip delivery for the start of major demolition or roofing work
- Keep materials like timber and plasterboard separate if you plan to recycle or reuse
- Book multiple skips or arrange for exchange if your builder expects ongoing waste
6. Site Access and Loading
Loft conversions can be tricky when it comes to waste handling — especially if access to the property is limited. Consider how waste will be carried out of the house:
- Will it come down through the house or out through scaffolding?
- Is there space for a skip close to the property?
- Will workers be able to load it easily as they go?
Discuss skip placement with your builder or contractor to keep your project running smoothly.
7. Safety and Cleanliness
Keeping your site clean isn’t just about appearances — it’s also about safety and efficiency. A well-placed skip helps keep materials off the ground, reduces trip hazards, and ensures nothing is left behind for you to clean up later.
Some builders may offer to arrange the skip themselves, but booking it directly gives you more control over cost, timing, and placement.
Hiring a skip for your loft conversion is one of the smartest decisions you can make — it keeps your project organised, compliant, and moving forward without delays.
- Choose the right size based on your waste type and project scale
- Avoid overloading by sticking to permitted weight limits
- Check if you need a permit (and let your skip company handle it)
- Plan waste disposal alongside your contractor to avoid last-minute issues
