Order a trial batchPick your municipalities and categories above. You see immediately how many addresses your territory holds and what it costs per month.
A fresh list by email every month: addresses with construction year, floor area, label status and the sales angle per home. Ready for direct mail or your door-to-door route.

That depends on your territory and categories. With cavity wall only it averages 50 to 150 addresses per delivery; every extra category adds addresses. The total number of available addresses per municipality is shown in the configurator above.
Email us at contact@huislens.nl. We then look at extra municipalities or categories together; there is always more territory.
Yes. Per municipality and per category there is exactly one client. We never sell the same address to two companies. That is the core of the product.
From a combination of government registers on buildings and professional, paid data sources. We join and analyse those sources at address level; you receive derived information about homes, no personal data and no raw register data. The lists are meant for direct mail ("to the residents of") and door-to-door, not for telemarketing.
The subscription can be cancelled monthly. Email contact@huislens.nl and we stop your subscription. Cancellation takes effect at the end of the current billing period.
