Air v Sea

  • A refrigerated container is commonly called a “reefer” container in shipping and logistics. It’s a specialised container with a built‑in refrigeration unit to maintain a set temperature for perishable goods in transit or storage.

  • Typical UK container purchase prices vary by condition:

    Container Type Approx UK Price
    Standard 20ft dry container – used ~£1,200–£2,500
    Standard 20ft – new ~£2,400–£4,500
    20ft reefer (refrigerated) – used ~£6,000–£8,500
    20ft reefer – new ~£9,000–£12,500

    Prices vary with condition, location, delivery and modifications.

    • Noise & vibration: Refrigeration units can be noisy at sites.

  • Hiring (renting) a 20ft container in the UK typically costs around:

    • £100–£300 per month for dry containers.
    • Reefers (refrigerated) usually cost more — often £12–£17 per day (dependent on supplier, hire period and location).

  • You can only live in a container legally if you get planning permission and satisfy building regulations.

    • A container used as a permanent dwelling is normally classed as a building, so full planning permission will almost always be needed.
    • Simply placing a container on your land temporarily may not require permission, but living in it requires approval. Always check with your local planning authority

  • For food that must stay chilled or frozen (e.g., dairy, fruit, meat), a refrigerated “reefer” container with active temperature control is best.
    If you only need to maintain temperature without active cooling, an insulated container (no power) may work for short durations but won’t control temperature like a reefer.

  • Yes — they are called reefer containers. They are widely used in the UK for transporting/storing perishables (food, pharmaceuticals, flowers, etc.) at set temperatures.

  • In the UK, rough cost ranges (2025 figures):

    • 20ft reefer (used): ~£6,000–£8,500
    • 20ft reefer (new): ~£9,000–£12,500
    • 40ft reefer (used): ~£9,000–£13,500
    • 40ft reefer (new): ~£14,000–£20,000
      (These are typical market prices and can vary.

  • In freight/logistics context, “Yeti” container isn’t an official term — people sometimes use it informally to describe a rugged, heavy‑duty insulated/refrigerated cooler (not a standard shipping container).
    In consumer terms, YETI is a brand of high‑performance coolers and drinkware known for insulation, but it’s not a type of shipping container.

  • A refrigerated container shouldn’t smell if clean and well‑maintained.
    Common smells arise if:

    • Food has spoiled
    • Condensation causes mildew
    • Drains or insulation hold moisture

    Proper cleaning and ventilation help keep odours down.

    • Refrigerated (reefer) containers:
      • Have a built‑in refrigeration system to maintain specific temperatures actively.
      • Used for long journeys or storage where precise temp control is required.
    • Insulated containers:
      • No active cooling — they maintain temperature by insulation alone.
      • Suitable only for short trips or maintaining temperature after pre‑cooling.
      • Cheaper and less energy‑intensive but not as precise as reefers.

  • Refrigerated containers are excellent for cold transport/storage, but there are some risks:

    • Power dependency: Refrigeration units need a reliable power source (mains, generator) — failure can spoil goods.
    • Maintenance costs: Reefers require annual servicing and regular checks.
    • Environmental impact: Refrigerants and energy use can have higher carbon impact.
