Build Sustainably with Energy Saving Products
Rising energy costs and stricter UK regulations, like the Future Homes Standard, demand smarter building choices. Inefficient lighting, poor insulation, and old boilers waste both energy and money. Choosing energy-saving products, such as smart thermostats and triple-glazed windows, helps you cut bills, comply with building regulations, and protect the planet. Find everything you need at Builder Depot to build greener, smarter homes all year round.
Improve insulation to keep heat in and bills down.
Lower your thermostat by 1°C to reduce energy use.
Choose A-rated appliances for maximum efficiency.
Switch to LED lighting – save energy and reduce costs.

Energy Labels Explained
About the A–G rescale
Older energy labels used classes like A+, A++ and A+++ at the top end, which meant many products clustered together. To give greater clarity and leave room for future improvements, many appliances are now labelled on a simple A–G scale, where A is the most efficient and G the least.
If a product that used to be A++ (or even A+++) now appears as C or D under the new scale, this does not mean the product has become less efficient — only that the benchmark for reaching the top has been raised. This creates headroom for newer, more efficient technologies to achieve the highest ratings in future.
The rescale was introduced in the UK from March 2021 for categories such as washing machines, dishwashers, fridges, freezers, lighting and TVs. Older labels may still be seen on products placed on the market before that date, so both styles can appear during the transition period.
In some cases, where there isn’t room to show the full label (for example on shelf tags), you may see a simplified version with a single coloured arrow and the letter grade alongside the A–G scale.

Illustrative only. Always compare labels within the same product type/size.
What does A–G actually mean?
The A–G scale compares energy efficiency within a product category. “A” is most efficient, “G” is least. It’s a quick way to see relative performance at a glance.
Are the numbers on the label the same for every product type?
No. The units differ by category (e.g., kWh per year for refrigeration, kWh per 100 cycles for laundry/dishwashers, kWh per 1000 hours for lighting/TVs). Compare like-for-like products only.
Why do larger appliances often have lower ratings?
Capacity matters. Bigger appliances can use more energy overall even if they’re efficient for their size. Check the label rating and the actual kWh figure.
Does the label show running cost?
Not directly. Running cost depends on your tariff and usage. Use our estimator to translate kWh into £ for your situation.
What else is on the label besides the letter?
Common icons include annual energy use (kWh), water consumption, noise level (dB), and capacity measures. These help you compare the things that matter for your install.
