Maassluis: historic harbour, post-war polders
Maassluis has a compact historic centre around the harbour, surrounded by the post-war Sluispolder districts, the Burgemeesterswijk and the recent new build of Het Balkon on the Nieuwe Waterweg. That spread means the label survey calls for something different per district.
When selling or renting out, a registered energy label is required, on pain of €515 (private) or €1,030 (legal entity). The label is valid for ten years from the survey date; a favourable class can earn a rate discount on a mortgage application.
Monument in the old city centre?
The Maassluis city centre around the Groote Kerk and the Govert van Wijnkade has many monumental and characterful properties. Since 29 May 2026 an energy label is also required for monuments when selling or renting. With single glazing and original frames the label is usually somewhat lower - that is normal and improvements are not mandatory. Read more in our article on the energy label for monuments.
How to request an energy label in Maassluis
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.
A label based on the construction year alone no longer exists: the provisional energy label lapsed on 1 January 2021 and registration has since required an on-site survey.
Energy label by neighbourhood in Maassluis
| Neighbourhood | Typical property type | Expected label |
|---|---|---|
| Historic centre & harbour | Monumental properties, often single glazing | D - F |
| Sluispolder-West & -Oost | Post-war homes 1950s - 70s | C - E |
| Vertoward, Steendijkpolder | Homes from the 1970s - 80s | C - D |
| Burgemeesterswijk | Homes from the 1990s | B - C |
| Het Balkon & new-build | Energy-efficient waterfront new-build | A - B |
How the property survey works
Allow 60 to 90 minutes. The BRL 9500 certified advisor records:
- Which surfaces border the outside, the crawl space or an unheated room
- How well roof, walls, floor and glazing insulate
- Which boiler or heat pump is installed, and how hot water is produced
- How the home is ventilated, and whether there are solar panels
What the glazing quote shows is the U-value of the glass, not of the window. In the label calculation the frame weighs in and the value shifts slightly. If you know the frame material and glass type, pass them on: the advisor then calculates exactly.
Which documents should you have ready for the survey?
What pays off most differs per district:
- Old centre: the renovation file with invoices for secondary glazing and insulation.
- Sluispolder or Burgemeesterswijk: the invoice for the cavity fill and the glass specification.
- Het Balkon or new build: the completion documentation.
- Always: boiler or heat pump and solar panels.
Without evidence the defaults for the construction year apply; for a seventeenth or eighteenth-century building those are the lowest assumptions.
First check whether a valid label already exists
A label from the past ten years, counted from the survey date, is still perfectly usable; EP-online shows it per address. Exceptions to the obligation are scarce these days: temporary buildings fall outside it, but listed buildings no longer do since 29 May 2026.
Energy label prices in Maassluis
Below you see per property type where the price starts. VAT, the on-site survey and the official EP-online registration are always included; the usable floor area does the rest. Background to the rates is in the 2026 price overview.
| Property type | From (incl. VAT) |
|---|---|
| Studio / room apartment | € 220 |
| Apartment | € 275 |
| Maisonette / terraced house | € 330 |
| Corner or semi-detached house | € 340 |
| Detached house | € 375 |
Nothing else is added: no travel costs and no surcharges, and you pay after delivery of the label. Monumental town-centre buildings and homes over 150 m²: fixed tailored price, known in advance.
Renting out in Maassluis: first the points, then the price
Up to and including 186 points the housing valuation system has prescribed the maximum rent since 1 July 2024, with 143 points as the line between social and mid-market rent. Because the energy label weighs heavily, one class of difference can shift the permitted rent noticeably. A rental points count can be combined with the label survey.
Certified work, without intermediaries
We work under BRL 9500, with InstallQ recognition and listing in the Centraal Register Techniek; only such a company may register labels in EP-online. And because the advisor who visits also registers the label personally, nobody stands between you and the result.
