Woerdense Verlaat: near Woerden, but not part of it
Woerdense Verlaat is a polder village on the edge of the Nieuwkoopse Plassen. The name misleads many people: the village does not belong to the municipality of Woerden but to the municipality of Nieuwkoop, in South Holland. The official town name in the Dutch address register is Woerdense Verlaat, and that name will appear on your energy label.
The housing stock is compact: some 240 homes, of which more than a third date from 1946 to 1974 and another fifth from 1975 to 1991. The median construction year is 1980. Pre-war ribbon buildings exist, but make up less than a tenth of the total.
Anyone selling or renting out here needs a registered energy label; without one you risk a fine of €515 as a private individual and €1,030 as a legal entity. Validity is ten years, counted from the survey date, and a favourable class can earn a rate discount on a mortgage application.
Living by the water and on the peat
The village lies between the lakes and the peat meadow area, and the survey reflects that. Homes by the water often have a wall or floor bordering surface water, and on peat a damp crawl space is more the rule than the exception. The advisor records both separately; preferably mention a wet or sealed crawl space in advance.

How to request an energy label in Woerdense Verlaat
You arrange an official energy label with us in three steps:
- Quote and appointment - calculate your price with the calculator or call us, and schedule the survey at a time that suits you.
- Property survey - our BRL 9500 certified advisor assesses insulation, glazing and installations following the NTA 8800 method.
- Registration in EP-online - you usually receive the definitive label within a few working days. In a hurry? Express delivery within 24 hours is possible.
The old provisional energy label lapsed on 1 January 2021. Only a label from a real survey may be registered in EP-online.

Energy label per property type in Woerdense Verlaat
The overview below follows the actual construction periods from the Dutch address and buildings register. It is indicative: the eventual class depends on the property itself and on what was done to it later.
| Property type | Share of the village | Expected label |
|---|---|---|
| Ribbon buildings from before 1945 | about 9% | D - F |
| Post-war homes 1946 - 1974 | about 37% | C - E |
| Homes 1975 - 1991 | about 22% | C - D |
| Homes 1992 - 2005 | about 19% | B - C |
| New build from 2006 | about 12% | A - B |
What our advisor measures during the survey
The property survey takes 60 to 90 minutes on average. Our BRL 9500 certified advisor records:
- All surfaces bordering the outside, crawl space, unheated rooms or water
- The insulation values of roof, walls, floor and glazing (U-values)
- The heating installation and hot water system (boiler, heat pump)
- The ventilation and any solar panels
A common misunderstanding: the U-value on your glass invoice applies to the pane only. The label calculates with the whole window, frame included, and a frame always insulates a little less well. If the advisor knows the frame type, no cautious assumption is needed.
Which documents should you have ready for the survey?
Especially for the post-war homes, evidence makes the difference. What helps:
- The invoice for cavity, floor or roof insulation, with product type.
- The glass specification for double or HR++ glazing fitted later.
- Make, type and year of the boiler or heat pump.
- Number and capacity of the solar panels.
- A floor plan or construction drawing, if available.
Without evidence the advisor calculates with the default values for the construction year, and for a 1960s home those are almost always worse than what is actually there.
When do you not need a new label?
If a registered label less than ten years old already exists, you can simply use it for a sale or rental. Check the survey date on EP-online. Beyond that a few exceptions to the label obligation apply, for instance buildings used only temporarily. Listed buildings have not been covered by those exceptions since 29 May 2026: a national or municipal monument now does need a valid energy label when sold or rented out.

Renting out in Woerdense Verlaat? The label counts towards your rental points
Since 1 July 2024 the housing valuation system is binding for all rental homes up to and including 186 points: up to 143 points social housing, 144 to 186 points mid-market rent. From 187 points the home falls in the free sector, where no legal maximum applies. The energy label weighs heavily in that count.
Certifications that safeguard reliability
Only a company working under the assessment guideline BRL 9500 may issue and register official energy labels. Recognition by InstallQ and inclusion in the Centraal Register Techniek give you extra certainty that you are working with a recognised party.
You always get the same fixed advisor, who surveys your property personally and registers the label as well. No call centre between you and the survey.
