You've got a letter on your energy label — maybe a C, maybe an F — and you're not entirely sure what it's telling you. It's simpler than it looks. The letter is basically a fuel-efficiency rating for your home.
The scale runs from A+++++ (the most efficient) down to G (the least). The higher up you are, the less energy your home wastes — which usually means lower bills, more comfort, and a home that's worth more when you sell or rent it.
The scale, top to bottom
A — and A+ up to A+++++
The efficient end. These homes are well insulated, often have modern or low-carbon heating, and sometimes generate their own energy with solar. Expect lower energy bills and a comfortable, even temperature. New-build and thoroughly renovated homes usually land here. The extra plus signs (A+ through A+++++) mark increasingly efficient homes above a standard A.
B and C — the solid middle
Very common for Dutch homes that have had some upgrades — better glazing, decent insulation, a reasonably modern boiler. Comfortable to live in, sensible running costs. A C is a perfectly respectable, sellable rating.
D, E, F and G — the older end
Typically older properties with limited insulation, single or older double glazing, or an older heating system. They can still be lovely homes — many characterful 1930s houses sit here — but they use more energy, so bills run higher. This is also the range that matters for the 2029 rental rules, where a minimum of D applies for letting.
What your letter actually affects
- Your bills. A higher letter generally means less energy wasted and lower monthly costs.
- Your comfort. Better-rated homes hold heat more evenly — fewer cold rooms and draughts.
- Your mortgage. An A or B can qualify you for a bank interest discount of around 0.2% — roughly €700 a year on a €350,000 mortgage.
- Your home's value. Better-rated homes tend to sell for more and faster; the gap between a C and a G can be significant on an average Dutch property.
- Renting it out. From 2029, rental homes need at least a D.
Is a low letter a problem?
Not for selling or renting today — you can still transact with any rating; the label just has to exist and be registered. A lower letter simply tells you there's room to improve, and roughly what it might be costing you. If you're curious what would lift it, our guide to improving your score covers the changes that count.
Don't guess — know
Many homeowners assume they know their energy label, but the only way to be sure is an official assessment. Once you have your Dutch energy label, you'll know exactly what it means, how it affects your home, and whether improvements are worth considering.
