Types of fridges and fridge freezers

What size fridge or fridge freezer do I need?

Whether you’re looking for a regular size fridge or a slim fridge freezer to fit into a tight space, you’ll find fridge capacity measured in litres. And while you can pop into Currys and ask for a large fridge freezer, it’s otherwise quite difficult to visualise what litres actually mean in terms of fridge space. So, here’s a quick capacity guide to help:

Fridge energy ratings

Every fridge and fridge freezer comes with an energy rating label, showing how energy‑efficient it is and an estimated yearly running cost. As fridges run 24/7, choosing a more energy‑efficient model can make a noticeable difference to your energy bills over time.

What is an energy rating?

Energy ratings typically range from A (most efficient) to G (least efficient). An A‑rated fridge freezer will usually cost more upfront, but it uses less electricity, which can help reduce long‑term running costs compared with lower‑rated models.
When comparing models, it’s worth looking beyond the letter rating and checking the annual energy consumption (kWh) on the label. This gives you a clearer picture of how much energy a fridge or fridge freezer is likely to use in real terms.

Fridge energy labels explained

Fridges and fridge freezers are using energy around the clock. So, choosing an efficient model can help to keep your running costs down.

The current energy label scale runs from A to G – with A being the most efficient. These ratings make it a lot easier to compare products and quickly understand how much energy they use each year.

You’ll see energy labels on our product pages online, as well as on the appliance itself. They include a lot of useful info, like energy consumption, its capacity and how much noise it’ll make. All of this is good to know before you spend any cash.

Older fridge labels explained

If you’re replacing an older fridge, there’s a good chance you’ll have come across ratings like A or A+++. These were part of the old energy label system.

Today’s labels use the stricter A to G scale. This means that a lot of highly efficient fridges that would once have been rated A+++ might now get a D, E or F rating.

Don’t let a lower letter put you off though. The newer system just sets a much higher benchmark, so you’re still getting an efficient appliance.

How do I save energy?

Air circulation

Air circulation tech uses special vents or metal cooling panels to keep the temperature consistent in your fridge. Instead of cold air staying in one spot, it’ll move evenly around every shelf. This reduces warm spots and stops temperatures from going up and down. Both help your food to stay fresh for longer. And it’ll preserve its flavour and quality too.

Overcrowding your fridge reduces the airflow and makes the fridge over-work, increasing your energy bills.

Fridge features worth looking out for

Water or ice dispenser

Love a chilled drink? Plumbed dispensers connect straight to your water supply, giving you a constant flow of water and more space for ice. On the other hand, non-plumbed models use a refillable inner tank. This makes them a bit easier to install and lets you put them wherever you like.

Low frost, no frost or frost free

Low frost reduces ice build-up and means you won’t have to defrost your fridge as often. While No frost/frost free tech stops ice from forming completely (so you’ll never need to defrost the appliance yourself).

Multi-door designs & configurations

Traditional 50/50, 60/40 and 70/30 (the split between fridge and freezer compartments) are the most popular options out there. American-style and multi-door models then offer extra room. And some make things even more energy efficient by letting you access one section at a time.

What size freezer do I need?

The right freezer size depends on how many people you’re buying for and how you shop. If you freeze lots of food in bulk or batch cook meals, a larger capacity will suit you better. Smaller households or anyone using a freezer as a secondary appliance can usually manage with less space.

Freezer capacity is measured in litres. As a rough guide, allow about 30–50 litres per person, then adjust depending on your habits. Chest freezers often offer the most capacity, while upright freezers make it easier to organise food and access items quickly.

Recommended freezer size by household

Household size Recommended freezer capacity
1 person Up to 100 L
2 people 100–150 L
3–4 people 150–250 L
4+ people 250 L and above

This gives you a practical starting point when comparing freezers, without paying for space you won’t use.

How to measure for a new freezer

Freezer energy labels explained

Every freezer comes with an energy label rating that shows how efficiently it uses electricity. The current scale runs from A to G, with A being the most energy efficient and G being the least.

A more efficient freezer could help to lower your energy bills over time. Just don’t be surprised if you don’t see that many A-rated models out there yet. The scale was redesigned to make room for any improvements further down the line. So, for now, most modern freezers generally sit somewhere between a C and an F rating.

You’ll find energy labels on our online product pages. They display the appliance’s rating, along with the annual energy usage. They also come attached to the freezer itself which makes it easy to compare models if you’re wandering around one of our stores.

Older freezer labels explained

You might be used to seeing freezer ratings like A+, A++ etc. These were part of the old energy label system.

The new labels use a simpler A to G scale. Because the requirements are a lot stricter now, a freezer that was rated A+++ under the old system could now get a C, D or even an F rating.

That doesn’t mean it’s less efficient. It just means the measuring system has changed. So, if you’re replacing an older A+ freezer with a new D-rated model, you don’t have to worry. The newer appliance could be just as energy efficient or even better!

Storage facilities

Many chest freezers include one or more storage baskets suspended over the main compartment – use them to store smaller items like bags of frozen vegetables or oven chips for easy location and to prevent spillages.

Some freezers have an extra-large drawer or basket for storing large, awkward goods such as Christmas turkeys, large cuts of meat or whole fish.

Transparent drawers let you easily check the amount and condition of your remaining groceries, without having to constantly open drawers and let cold air escape.

Star rating

How long you can store frozen food depends on the freezer’s rating, which ranges from 1-star to 4-star. The higher the rating, the colder the freezer and the longer you can store food safely. A 4-star rating means you can safely store food for up to 12 months. Lower ratings are for short-term storage only.

1-star ice box – operates at a minimum temperature of -6 degrees Celsius

2-star ice box – operates at a minimum temperature of -12 degrees Celsius

3-star ice box – operates at a minimum temperature of -18 degrees Celsius

4-star freezer – operates at a minimum temperature of -18 degrees Celsius

Frost free

Frost-free freezers prevent icy build up, so you won't need to defrost them – plus you'll have more storage space. This means you can save time and effort, as you won’t have to go through the laborious defrosting process like with static freezers.

Static freezers require manual defrosting periodically to ensure optimum performance and storage conditions.
