Understanding the need for a storage unit

Before diving into the nitty-gritty, it's essential to understand why you need a storage unit.

Whether it's for residential or business storage, clarity on your requirements will guide your decision-making process. We'll also discuss common concerns and mistakes to avoid along the way.

1. Create a detailed inventory list

Begin by listing every item you intend to store. This includes furniture, boxes, appliances, and any other belongings. Creating a comprehensive list will serve as a valuable reference point throughout the process.

2. Categorise items based on size and fragility

Categorise your inventory based on the size and fragility of items. This classification will not only help you in selecting an appropriately sized unit but also in planning for the safe storage of delicate items.

Small items

Fragile items

Glassware, artwork, etc.

3. Evaluate storage needs

Assess the space requirements for each category. This evaluation will help determine the ideal unit size and layout to accommodate your belongings comfortably.

Types of storage units

Choosing the right storage unit size is crucial for a successful storage experience. Let's explore the different storage unit sizes and types, catering to various needs – from your personal items to full household storage.

Small Units

  • Personal items: Small storage units are ideal for storing personal belongings such as clothing, books, and small electronic devices.
  • Documents: If you need a space to store important documents or files, a small unit provides a secure and organised solution.
  • Small furniture: Items like chairs, bedside tables, or small coffee tables find a suitable home in these compact units.

Medium Units

  • Larger appliances: Medium-sized units accommodate household appliances like microwaves, fans, or small kitchen appliances.
  • Multiple furniture items: If you have several pieces of furniture, including medium-sized tables or bookshelves, a medium storage unit offers ample space.

Large Units

  • Full household storage: Large storage units are designed to accommodate the contents of an entire household. This includes furniture, appliances, and various personal belongings.
  • Large items: Items like sofas, mattresses, and other sizable furniture pieces can be easily stored in a large unit.

Factors to consider when choosing a storage unit

When selecting a storage unit, several crucial factors come into play.

Consideration of climate control, accessibility, and security features is paramount in ensuring the safety and preservation of your stored items.

Climate-controlled units

Climate control units offer benefits for sensitive items:

  • Preserving condition: Climate-controlled units maintain a consistent temperature and humidity level, safeguarding sensitive items such as wooden furniture, electronics, and delicate fabrics.
  • Preventing mold and mildew: By regulating environmental conditions, these units minimise the risk of mold and mildew growth, crucial for preserving the integrity of your belongings.

Accessibility and location

Convenience and ease of access:

  • Proximity: Opt for a storage facility that is conveniently located, reducing travel time when you need to access your items.
  • Accessibility: Consider storage units with ground-level access for easier loading and unloading, especially if you plan on frequent visits.

Security measures

Ensuring the safety of your belongings:

  • Surveillance systems: Look for storage facilities equipped with 24/7 surveillance systems to deter theft and unauthorized access.
  • Secure access: Facilities with gated access and personalized entry codes provide an extra layer of security, limiting access to authorized individuals.
  • Well-lit areas: Adequate lighting in and around the storage facility enhances visibility, contributing to a safer environment.

Cost considerations

When comparing prices, understanding contracts is crucial. Let’s dive into evaluating price versus size and choosing between long-term and short-term rentals based on your storage duration.

Evaluating price vs. Size

  • Size optimisation: Consider the volume of items you plan to store. While larger units may seem tempting, opting for a size that aligns with your needs prevents overpaying for unused space.
  • Unit features: Evaluate the features offered by different units. Sometimes, paying a slightly higher price for added benefits such as climate control or enhanced security can be a prudent investment.

Unit Size

Approximate Volume

Average Monthly Cost


25-75 sq ft



100-150 sq ft



200+ sq ft


Long-term vs. Short-term rentals

Long-term considerations: If you anticipate the need for storage extending over several months or years, inquire about potential discounts for long-term commitments.

Flexibility with short-term rentals: For shorter durations, flexibility becomes key. Ensure that the terms of short-term rentals align with your expected storage timeframe.

By carefully examining the relationship between price and size and weighing the benefits of long-term versus short-term arrangements, you can optimize your storage solution to meet both your needs and budget.

Packing and organising your storage unit

Efficient packing tips

  • Use uniform boxes: Opt for boxes of similar sizes to facilitate stacking and minimize unused spaces.
  • Protect fragile items: Wrap delicate items in bubble wrap or packing paper and consider using furniture covers for added protection.
  • Label everything: Clearly label each box with its contents. This not only aids in finding items later but also ensures careful handling of delicate possessions.
  • Use quality packing materials to ensure items are properly protected whilst in storage and during the move.

Organising for easy access

  • Access paths: Plan for clear pathways within the unit to easily reach items at the back.
  • Frequent access items: Place items you might need to access frequently towards the front for easy retrieval.
  • Categorisation: Group similar items together. This helps in locating specific belongings without the need to sift through everything.

Efficient packing and strategic organisation not only optimise the use of your storage space but also simplify the retrieval process, turning your storage unit into a well-organized extension of your space.

Making the final decision

Let’s compare your options!

Now that you've assessed your needs, considered various factors, and explored the types of storage units, it's time to compare your top choices.

Create a checklist of priorities, including factors like size, features, and cost. And don’t forget to look into customer reviews and testimonials for insights into the experiences of others.

Sometimes, your gut feeling plays a crucial role in decision-making. Trust your instincts when it comes to choosing a storage unit. If a particular facility or unit resonates with you and aligns with your requirements, it might be the right fit!
