Is an Old Open-Front Fridge Quietly Eating Your Margin?
Energy savings are easy to talk about and hard to trust. Operators have heard too many neat payback claims. A better question is this: what is your old open-front fridge telling you through the electricity bill, room temperature, noise, temperature logs and merchandising performance? If it is fighting the shop every day, replacement may be less about buying new kit and more about stopping a slow leak in margin.
- Doors can cut energy dramatically: like-for-like glass-door cabinets often use far less electricity than open-front equivalents.
- Energy labels are a comparison tool: use annual kWh figures to estimate running cost using your own tariff.
- Old cabinets often lose twice: they use more power and may heat the shop, increasing the burden on comfort cooling.
- Do not judge by energy alone: impulse sales, product visibility and customer behaviour still matter.
- Replacement should be audited: compare energy, reliability, food safety, merchandising and serviceability.
Craven already has an open-front versus glass-door energy guide, so this blog takes the operator’s decision point: when is the existing cabinet costing enough to justify action?

Start With Your Own Numbers
Take the annual kWh from the cabinet label or technical sheet and multiply it by your electricity rate. Then compare it with a modern alternative. Do not borrow someone else’s tariff or payback claim; your opening hours, tariff and cabinet condition decide the answer.
Use the label or manual, or ask the supplier for the data.
Multiply kWh by your actual pence-per-kWh cost.
Frequent call-outs change the economics quickly.
Check Whether the Cabinet Still Supports Sales
An open-front display may still be right for some high-footfall impulse locations. But if products are not visible, shelves are poorly lit, the cabinet is noisy, or shoppers avoid the cold aisle, the old display may be underperforming commercially as well as electrically.
| Signal | What it suggests | Action |
|---|---|---|
| High bill and warm aisle | Cold air loss | Compare glass-door options |
| Temperature drift | Capacity, maintenance or airflow issue | Service first, then assess replacement |
| Frequent repairs | End-of-life risk | Cost replacement against downtime |
Doors Are Not the Only Upgrade
Sometimes the answer is a glass-door multideck. Sometimes it is a smaller cabinet, better lighting, a night blind, a different merchandising position or splitting chilled stock across two displays. The replacement should solve the trading problem, not just reduce a kWh figure.
Make the Decision Before the Breakdown
The worst time to choose a cabinet is after a failure, with stock warming and staff improvising. If the numbers point toward replacement within the next year, plan the change around a quiet trading period and confirm delivery route, power and layout before ordering.

An old open-front fridge should be judged by energy use, reliability, temperature control, merchandising and repair risk. Use your own kWh and tariff figures, then compare whether a modern glass-door or alternative display would protect margin better.
