How much does a wine fridge cost to run per year in the UK?
A 16 bottle compressor wine fridge rated at 133 kilowatt hours a year costs about £35.01 a year to run at the Ofgem cap rate of 26.32p per kWh, which is £2.92 a month or 9.6p a day. Across the models we checked the range runs from £18.95 a year for a 6 bottle thermoelectric cooler to £38.16 for a 46 bottle built in cabinet.
What a wine fridge actually uses
A wine fridge does not run flat out, so the watts on the back tell you very little about the bill. Subcold's Viva16, a 16 bottle freestanding compressor cooler, lists an input power of 50 watts, and that is only what it draws while the compressor is running. The figure that counts is on the energy label, which Subcold gives as 133 kilowatt hours a year. Spread over every hour of the year that is an average of about 15 watts, roughly the equivalent of the compressor running for seven hours in every twenty four.
At the Ofgem cap rate of 26.32p per kilowatt hour, 133 kilowatt hours costs £35.01 a year. That is £2.92 a month and 9.6p a day, and the cooler costs the same whether there are two bottles in it or sixteen, because what it pays for is keeping the cabinet cold.
Work it out for your own wine fridge
Type in the wattage from the plate on the back, then your own unit rate. The numbers update as you type.
The calculator starts at that 15 watt average over a full day. If your own model has a different kilowatt hour figure on its label, divide it by 8.76 to get the average watts and leave the hours at 24.
What different sizes cost to run
A bigger cooler costs more to run, but the bill grows much more slowly than the number of bottles it holds, which is clear from the manufacturers' own ratings for four coolers.
| Model and type | Bottles | Rated kWh a year | Per day | Per month | Per year | Per bottle a year |
|---|---|---|---|---|---|---|
| Subcold Barcool Vino6, thermoelectric | 6 | 72 | 5.2p | £1.58 | £18.95 | £3.16 |
| Baridi DH73, thermoelectric | 12 | 92 | 6.6p | £2.02 | £24.21 | £2.02 |
| Subcold Viva16, compressor | 16 | 133 | 9.6p | £2.92 | £35.01 | £2.19 |
| Caple Wi6135, dual zone under counter | 46 | 145 | 10.5p | £3.18 | £38.16 | £0.83 |
The biggest cabinet costs the most in total and by far the least for each bottle. The 46 bottle Caple uses about twice the electricity of the 6 bottle Subcold and holds nearly eight times as much wine, so a collector who has outgrown one small cooler is usually better off replacing it than buying a second one.
| Appliance | Typical draw | Usage we assume | Per hour (UK) | Per usage (UK) | Per month (UK) | Per hour (US) |
|---|---|---|---|---|---|---|
| Wine fridge | 133 kWh a year | per year, compressor or thermoelectric cycling included | 0.40p | £35.01 | £2.92 | 0.28 cents |

Why a G rating does not mean a big bill
Most wine fridges carry an energy class of E, F or G, which looks alarming next to a modern fridge freezer. The letter rates how efficient the cabinet is for its size and type, and the kilowatt hours printed beside it are what you actually pay for. The 46 bottle Caple is class G at 145 kilowatt hours, and the 6 bottle Vino6 is class E at 72, so the cabinet with the worse letter costs less than double to run while holding far more. When you compare two models, compare the kilowatt hours a year and the bottle count, and treat the letter as a tiebreak.
Thermoelectric or compressor
Small worktop coolers often use a thermoelectric module instead of a compressor. They have no compressor kicking in and out, which suits a living room or a bar, but they are not the cheap option per bottle. The Vino6 uses 12 kilowatt hours a year for every bottle it holds, while the compressor Viva16 manages about 8.3.
They are also limited in how cold they get. Baridi gives its thermoelectric DH73 a range of 12 to 18 degrees, which is right for storing red wine but will not chill a white to drinking temperature, while the compressor Viva16 goes down to 3 degrees. Baridi also points out that its cooler will not reach a temperature higher than the room, because a thermoelectric unit can only take heat away.
Where you put it changes the cost
Every model we checked is climate class N, which the manufacturers state as a room between 16 and 32 degrees. The label figure is measured inside that range, and a cooler in a warm spot works harder than one in a cool one, since more heat leaks in through the door and walls for the cooling to pump back out.
That makes a sunny conservatory or the gap beside a radiator the worst places for one, and a cool hallway or dining room among the best. An unheated garage fails the other way, because in a British winter it drops well below the 16 degree floor the rating assumes. A built in model also needs its air path kept clear. Caple vents the Wi6135 through a grille in the plinth, so a kickboard fitted over that grille traps the heat the cooler is trying to get rid of.
Wine fridge against your fridge freezer
A typical full size fridge freezer is rated at about 258 kilowatt hours a year and costs £67.91 to run, so a 16 bottle wine fridge adds a little over half as much again to the cost of keeping things cold. Over a year the Viva16 costs £35.01, about the same as leaving a 15 watt light on day and night, and the money is in the bottles rather than the electricity.
Keeping the running cost down
- Set it to the temperature the wine needs. A cooler held at 12 degrees for red has less heat to pump out than one held at 5, and storage wine does not need to sit at fridge temperature.
- Choose the size you will actually fill, because an empty shelf costs the same to keep cold as a full one.
- Keep it away from ovens, radiators, dishwashers and direct sun, and leave room behind and around a freestanding model for the warm air to escape.
- Switch it off and prop the door open if it will stand empty for months, such as after the Christmas stock has gone.
- Keep the door closed. Every opening lets warm kitchen air into the cabinet.
Is a wine fridge worth it on running cost
On electricity alone a 16 bottle wine fridge costs about £35 a year, £2.92 a month, which is small next to the value of even a modest collection. The running cost should not stop you buying one. What makes the difference is choosing a compressor model sized to the bottles you keep and putting it somewhere that stays between 16 and 32 degrees all year.
Common questions
Are wine fridges expensive to run?
Not compared with the main fridge. A 16 bottle compressor model rated at 133 kilowatt hours a year costs £35.01 a year at the current cap, about £2.92 a month, and a full size fridge freezer rated at 258 kilowatt hours costs nearly twice as much.
Does a small wine fridge use a lot of electricity?
Less in total, but more for each bottle. Subcold rates its 6 bottle Barcool Vino6 at 72 kilowatt hours a year, which is £18.95, and that works out at 12 kilowatt hours a bottle against about 8 for its 16 bottle Viva16. If you have more than six bottles to keep, one larger cabinet costs less than two small ones.
How many watts does a wine fridge use?
The plate figure is around 50 to 55 watts for a small freestanding model, which is what it draws while the cooling is running. Averaged over the year, the 133 kilowatt hours on the Viva16 label is about 15 watts, and that average is the figure that sets the bill.
Can you put a wine fridge in the garage?
Only if the garage stays above 16 degrees. The Subcold, Baridi and Caple models we checked are all climate class N, rated for rooms between 16 and 32 degrees, and an unheated UK garage drops well below that in winter. A thermoelectric cooler also cannot warm the bottles, so in a cold garage the wine simply sits at the temperature of the garage.
