Getting the skip size right before delivery saves more time and money than most people expect. Too small and the skip fills before the job is done, leaving you waiting for a swap or a second hire. Too large and you’re paying for capacity sitting empty on the driveway. Our skip size guide covers the practical decisions involved — matching the skip to the waste type, volume, and the physical realities of the site — so you can book with confidence rather than guesswork.
The skips we offer and what they’re suited to
We offer four skip sizes suited to different scales of project, and the right choice depends on what you’re disposing of as much as how much of it there is.
The 4 tonne midi skip is the most popular choice for domestic projects — household clear-outs, garden tidies, bathroom or kitchen strip-outs, and light renovation work. It sits comfortably on most driveways, doesn’t require particularly wide access, and handles a substantial volume of mixed household and garden waste. For a single room refurbishment generating plasterboard, tiles, old fixtures, and packaging, a midi skip is usually the right call.
The 8 tonne builders skip is the standard choice for larger renovation and construction work — extensions, loft conversions, full kitchen and bathroom renovations, commercial fit-outs, and projects where waste is coming from multiple trades simultaneously. It handles the heavier mixed loads that building work generates: concrete, bricks, timber, plasterboard, and packaging all in one load. If your project is likely to run for more than a day or two of active waste generation, the builders skip is almost always the more economical option because it removes the risk of filling up and needing a swap mid-project.
For larger commercial sites, demolition projects, or high-volume clearances, our roll-on roll-off options provide significantly greater capacity. The 20 yard RoRo handles the kind of volumes that would otherwise require four or five standard skip swaps, making it far more practical on active commercial sites. The 40 yard RoRo is suited to the largest demolition and commercial clearance work where waste is being generated continuously over an extended period. More detail on when RoRo skips make sense is covered in our RoRo guide.
Why waste type matters as much as volume
Volume is the obvious variable — how much waste is there? — but waste type has an equally significant influence on which skip is right for a job, and it’s the one people less often think through in advance.
The most important distinction is between light bulky waste and heavy dense waste. Garden waste — cuttings, turf, prunings, soil — is bulky and awkward to stack, which means it fills a skip by volume much faster than its weight would suggest. A skip full of garden waste will typically be nowhere near its weight limit when it’s physically full. Heavy inert materials — concrete, bricks, hardcore, excavated subsoil — do the opposite: they can bring a skip to its weight limit at half capacity without looking full. A skip loaded predominantly with rubble that hits its weight limit before it’s visually full still incurs the full hire cost and may attract an overweight surcharge on collection.
If your project combines both types — say a garden clearance that also involves breaking up an old path or removing a brick wall — it’s worth thinking about how to balance the load. Mixing heavy inert material with lighter garden or household waste helps spread the weight more evenly across the skip’s capacity. If there’s a very large quantity of heavy inert material, a separate arrangement specifically for that stream often works out more cost-effective than filling a standard skip with it.
Mixed renovation waste — plasterboard, timber, tiles, packaging, carpet — loads well and is the most common skip content we see. It’s generally predictable in terms of weight and volume, and a midi or builders skip will handle it without the weight complications that come with heavy inert material. The exception is if significant quantities of plasterboard are involved: plasterboard is best kept separate from biodegradable waste where possible, and on larger projects a dedicated pile or even a separate small skip for plasterboard specifically can improve the recycling outcome and reduce disposal costs.
How to estimate volume before you book
The most practical way to estimate waste volume before booking is to think in terms of what the waste actually looks like piled up, rather than in abstract measurements. A standard wheelie bin holds around 0.24 cubic metres, which gives a rough reference point — but the more useful approach is to walk around the project and think about how much floor space the waste would cover, and how high it would stack, before it’s loaded into a skip.
For household clear-outs, the number of rooms being cleared and the density of their contents gives a reasonable guide. A heavily furnished room with old appliances and built-in units generates significantly more volume than a lightly furnished one. For renovation work, the scope of demolition is the key variable — a full strip-out back to brick generates far more waste than a cosmetic refresh of the same room. For garden projects, the footprint of what’s being cleared and the depth of soil being moved are the most useful measurements to think through.
If the estimate is genuinely uncertain, the bias should be towards going one size up rather than down. The price difference between adjacent skip sizes is typically much smaller than the cost of a swap or a second hire, and a skip with some spare capacity at the end of the job is a much better outcome than one that fills before the work is finished. If you want to talk through a specific project before booking, our team can help work out the right size based on what you describe — call us on 01704 779345 and we’ll give you a practical answer rather than defaulting to the largest option.
Site access and placement — practical considerations
Skip size decisions don’t happen in isolation from the physical reality of the site. A skip that’s theoretically the right size for the waste is only useful if it can actually be delivered and positioned where you need it.
Driveway placement is the most common arrangement and generally the most straightforward, but it’s worth measuring available width before booking — skip lorries need reasonable clearance to manoeuvre, and the skip itself needs to fit without blocking access to the property or neighbouring driveways. On older residential streets across West Lancashire, particularly around the terraced housing in Ormskirk and Southport, access can be tighter than it appears from the street, and it’s worth a conversation before assuming a large skip can go where you’re planning.
If the skip needs to go on a public road, a permit from the relevant council is required before delivery. We handle permit applications as part of the booking for roadside placements — full detail on how that works is in our Lancashire permit guide. For roadside positions, the midi skip’s smaller footprint is generally more practical than a full builders skip on narrower streets.
Covering the full West Lancashire area
We deliver across the full West Lancashire and Merseyside service area — Ormskirk, Southport, Burscough, Formby, Skelmersdale, Leyland, Chorley, Bamber Bridge, Crosby, and the surrounding villages. For customers in Southport and Skelmersdale the same skip range is available with the same approach to sizing advice — the projects vary across the area, from the large Victorian and Edwardian properties in Southport generating substantial clear-out volumes, to the industrial and commercial sites around Skelmersdale where builders skips and RoRo options are in frequent use.
With over a century of skip hire experience in West Lancashire, we’ve seen every variation of project size and waste type the area produces. That experience feeds directly into the sizing advice we give — not generic rules of thumb, but practical guidance based on what projects like yours actually generate. To discuss your project and get the right skip booked in, contact our team online or call us on 01704 779345 for Ormskirk, Southport, and surrounding areas, 01695 769123 for Skelmersdale, or 01772 364399 for Leyland and Bamber Bridge.
