Connectivity as value: why coverage makes your building worth more.

As an investor or landlord, you know the classic value drivers by heart: location, floor area, condition of the building, and increasingly the energy score. But a new factor has emerged, one that appears on no energy certificate or floor plan, and that tenants notice first today: do I have decent mobile coverage inside here?

It sounds trivial until you realise what hangs on it. A building where your smartphone falters is a building with a hidden defect. And hidden defects cost money — when renting, when selling, and every day in between.

Coverage is the new basic utility

Twenty years ago, no one asked about internet in a building. Ten years ago, Wi-Fi became an expectation. Today, reliable mobile coverage has become a basic utility, on the same level as water, electricity and heating.

The reason is simple: people rely on their phone for everything that matters. Working, banking, two-factor authentication, emergency calls, remote-work calls. A tenant with no signal indoors doesn't experience that as a minor inconvenience, but as a fault in the property itself.

A building without proper coverage is like a building with a leaking roof you can't see: it functions, until the moment the tenant notices — and then it's your problem.

What it actually costs you (or earns you)

For the investor, coverage translates directly into the figures you do have on your dashboard:

• Rental value. Offices, retail and residential with proven good indoor connectivity rent faster and at a better price. It's a selling point that competitors often can't demonstrate.
• Vacancy. Properties with coverage problems stay empty longer and see more tenant turnover. Every month of vacancy is a direct loss of return.
• Tenant retention. A tenant who works smoothly stays. A tenant who has to walk to the window every day to make a call looks around at the next renewal.
• Negotiating position. At renewal or sale, 'perfect indoor coverage, certified' is an asset; 'poor coverage' is a price depressor.

The asset value itself: from defect to asset

Think of coverage the way you think of the energy score. A poor energy certificate lowers value and scares off buyers; a good one is a selling point. Connectivity follows exactly the same curve, just a few years later on the timeline.

The first signs are already here: new office buildings are marketed on their connectivity, and professional tenants — especially in healthcare, retail and logistics — include indoor coverage in their requirements. For ASTRID indoor coverage (the emergency-services network) it has even become a legal requirement in many building types. Investing in coverage today means getting ahead of a standard that's coming regardless.

The question for an investor isn't whether connectivity will become a value factor. That question is outdated. The question is whether your portfolio is ready for it before the market forces the issue.

The good news: it's a manageable investment

Unlike an energy retrofit, indoor connectivity can be solved relatively simply and in a targeted way. You don't have to open up your façade.

• In new construction or renovation, you simply plan an indoor system into the design — a fraction of the build cost, with lasting added value.
• In existing real estate, a system can almost always be retrofitted, tailored to the exact spots where the signal drops out.
• It starts with measuring. A coverage analysis shows in black and white where you stand — and that report is immediately usable in your leasing and sales file.

The beauty: it's a one-off investment in a fixed installation that structurally upgrades the asset — not a recurring cost, but a lasting characteristic of the building.

In short for the investor

• Coverage has become a basic utility; its absence is a hidden defect.
• It affects rental value, vacancy, tenant retention and sale price — all hard figures.
• Connectivity follows the same value curve as the energy score, with regulation on the way.
• The solution is targeted, one-off and value-adding — not a structural renovation.

You don't rent out square metres. You rent out a place where people can work and live without worry. Coverage is today an inseparable part of that.
