Overcharged or Ripped Off by a Mandatory Window Inspection Contractor? Recovering Your Money

If your building is old enough, a statutory notice from the Buildings Department eventually lands in your letterbox: get your windows inspected, or face a fine. Most owners just grit their teeth and hire someone. The trouble starts right there — this building-safety scheme has, for years, come with a documented pattern of complaints: companies advertising a "free inspection" that turns out to carry a fee once the paperwork is filed; inspectors claiming a worn window seal needs replacing when it has nothing to do with the mandatory requirement; and, in some cases, the person who actually shows up isn't even on the Buildings Department's own list of qualified inspectors. This article isn't about picking a good contractor — it's about a narrower, practical question: if you suspect you've been overcharged or shortchanged, what evidence do you need, and how do you get the money back?

What the Mandatory Window Inspection Scheme Actually Requires

First, the scheme itself. According to the Buildings Department, the Mandatory Window Inspection Scheme applies to private buildings 10 years or older (excluding domestic buildings of 3 storeys or below). Once an owner is served a statutory notice, they must engage a Qualified Person to carry out a prescribed inspection of all windows in the unit; if the inspection finds repair work is needed, the owner must also ensure that work is supervised by the Qualified Person.

This isn't a "notice arrives, box ticked" situation. The Buildings Department has itself published a real case: an owner who failed to comply with a statutory notice was fined over HK$150,000 by the Kwun Tong Magistrates' Court — under section 40(1BD) of the Buildings Ordinance, the court imposed the fine plus an additional HK$2,000 for every day the non-compliance continued, accumulated over roughly 300 days. In other words, ignoring the notice is not a real option — but that doesn't mean you should accept whatever a contractor charges you for it. The scheme's seriousness and whether you've actually been overcharged are two separate questions.

It's also worth knowing that the Buildings Department's own execution of the scheme has drawn criticism from the Ombudsman's Office. A proactive Ombudsman investigation found the Department received about 50 complaints about its own handling of the scheme between its 2012 launch and 2018. This doesn't lessen an individual owner's own obligation to comply — but it does explain why the market for inspection services has ended up with more than a few unreliable operators.

Before You Pay, Know the Documented Overcharging Traps

Based on complaint patterns compiled by the Consumer Council, the recurring problems break down roughly like this:

• The person isn't on the list. Some consumers discovered the inspector sent by the company simply wasn't on the register of qualified persons. If that happens, you've paid — but the statutory requirement may not actually have been satisfied.
• False claims about needed repairs. Inspectors sometimes claim aging weatherproof sealant or glass sealant needs costly replacement, when these items fall outside the scope of the mandatory inspection and have nothing to do with window safety.
• "Free" still costs money. Many companies advertise a free inspection to attract customers, but even when no repair is found necessary, consumers are typically still charged a documentation/filing fee for the paperwork submitted to the Buildings Department — this is the exact point where the "free" framing misleads.

Beyond the Consumer Council's own material, market reporting also describes a low-quote-then-inflate pattern: a company quotes a low inspection fee, then sharply raises the price once it "discovers" a problem, sometimes implying you'll "fail" inspection if you don't follow their recommendation. A variant of the same tactic is refusing to give a written, itemised quotation at all — only a verbal figure — until the work is already done, at which point there's no paper trail left to dispute. One thing worth remembering: the company that inspects your windows doesn't have to be the one that repairs them. You're free to take the inspection report and get competing quotes from other registered contractors, and comparing two or three quotes before committing to any repair is genuinely the simplest protection available.

Verifying an Inspector's Identity Before You Pay

The single most practical step is verifying identity before any money changes hands. The Consumer Council and other reporting point to two concrete checks:

1. Ask to see the Window Inspection Card. Every qualified inspector should hold a card issued by the Buildings Department, showing their name, photo, registration number and expiry date. Asking to see it before paying is the most basic form of self-protection.
2. Check the Buildings Department's own register. The Department maintains an online search tool for qualified persons, which lets you confirm whether both the company AND the individual who actually shows up are on the list — a registered company does not guarantee the person sent that day is a registered individual.

Verifying upfront also means that, if a dispute or complaint follows later, you already have a record of exactly who attended — rather than relying on memory afterward. This is the same discipline our evidence preparation guide emphasises throughout: record things while they're still fresh.

Already Overcharged? Here's the Evidence That Matters

If money has already changed hands and you're only now realising something is wrong, don't panic — focus on assembling evidence:

• The original quotation and advertising wording — a screenshot of the "free inspection" ad, or any WhatsApp record of the sales pitch
• The final invoice — itemising each charge, compared against what was originally promised
• A record of the inspector's identity — a photo of their Window Inspection Card or their name, if you captured it
• An independent opinion, where relevant — if the dispute is about whether a repair was genuinely necessary, a written opinion from another qualified inspector or registered contractor strengthens your position considerably

None of this needs to be complicated to be useful — a folder of screenshots, saved messages and one clear invoice is usually enough for a Tribunal adjudicator to follow what actually happened, without needing a lawyer to organise it for you.

If a "free inspection" advertisement was never intended to be genuinely free, that kind of marketing may raise a Trade Descriptions Ordinance (Cap. 362) issue. According to Hong Kong Customs, false trade descriptions, misleading omissions and bait advertising are all regulated unfair trade practices, and Customs is the primary enforcement authority. Worth noting: Customs' role is mainly regulatory enforcement, not getting your individual loss back — so this step runs alongside your own money claim, not instead of it.

This same discipline — keep the evidence first, and separate what's genuinely required from what's a sales pitch — is the same principle we saw in a repair-dispute case we handled: what a Tribunal adjudicator actually weighs is whether you can produce clear invoices, correspondence and comparisons, not who argues more persuasively.

Recovering the Money — Consumer Council, Customs or the Tribunal

Once your evidence is in order, there are a few different routes depending on your goal:

• The Consumer Council — if you want to report an unfair sales practice, or want an independent record of the complaint. The Council can't force a refund, but its involvement sometimes prompts a trader to refund voluntarily.
• Hong Kong Customs — if you suspect the "free inspection" advertising itself involved a false trade description or misleading omission, you can report it and let Customs decide whether to investigate. This is regulatory enforcement, not a route to recover your own individual loss.
• The Small Claims Tribunal — if your goal is recovering an overcharged or wrongly billed sum, you can file with the Small Claims Tribunal, capped at HK$75,000. According to the Judiciary, hearings are conducted informally and parties cannot be represented by lawyers — meaning you can file and appear yourself even without legal training. For the actual filing steps, see our claim form guide and our Small Claims Tribunal guide.
