How to commission and calibrate bakery equipment

Once your main pieces of equipment have been installed, you must arrange for a qualified engineer to professionally ‘commission’ them. This is the final, expert check to test, adjust, and calibrate everything before you start baking for customers. This essential step turns your expensive new oven, mixer, and fridges into the reliable, consistent tools that will form the backbone of your bakery.

What is Commissioning and Why is it Crucial?

Think of commissioning as a professional handover. An engineer confirms that your equipment is installed correctly, runs safely, and is calibrated to perform exactly as it should in your kitchen. Skipping this can lead to serious problems and inconsistent products.

• Consistency is King: A successful bakery relies on making the same fantastic product every single time. If your oven's thermostat is off by 10 degrees, your recipes won't work. If your mixer speed is wrong, your dough won't develop properly. Calibration ensures your equipment does exactly what you tell it to.
• Food Safety: Proper commissioning ensures your refrigerators and freezers can hold a stable, correct temperature. This is a legal requirement for keeping ingredients safe and preventing the growth of harmful bacteria.
• It Validates Your Warranty: Many manufacturers will not honour the warranty on expensive commercial equipment unless you can prove it was professionally commissioned. The certificate you receive is your proof, so don't risk invalidating your guarantee.
• Efficiency and Lifespan: A well-calibrated machine runs more efficiently, saving you money on your energy bills. It also puts less strain on components, helping to extend the life of your investment.

Your Step-by-Step Guide

Getting your equipment commissioned is a straightforward process. Here’s how to approach it:

1. Contact Your Equipment Supplier First: The company that sold you the equipment is the best place to start. They will often have their own engineers or an approved partner who can carry out the work. This service might even be included in your purchase package.
2. Find a Certified Engineer: If your supplier can't help, you'll need to find an independent, qualified commercial catering equipment engineer. For any gas appliances, such as a gas oven, the engineer must be on the Gas Safe Register.
3. Be Present for the Visit: If you can, be there when the engineer visits. They will test oven temperatures against a calibrated thermometer, check mixer speed settings, and ensure refrigeration cycles are working correctly. It's a great opportunity to ask questions about using and maintaining the equipment.
4. Get the Commissioning Certificate: This is the most important part. The engineer must provide you with a report or certificate for each piece of equipment they commission. Keep this document in a safe place with your business records and warranty information.

Top Tip: Don't be tempted to skip professional commissioning to save a bit of cash upfront. The potential cost of ruined batches, wasted ingredients, unhappy customers, or a void warranty is far higher. It’s a crucial investment in the quality and safety of your bakery.
