SolutionsCompliance and deadlines
A lapsed certificate is not admin.
It is an increase you cannot send.
EPC, electrical, boiler, chimney, insurance, registration. Every statutory date on one calendar, each with the lead time it actually needs, and the appointment booked while there is still time to book one.
Dardaris is early and still moving. Nothing is switched on until you say so.

An expired EPC does not only fail an inspection. It blocks indexation, which is why that one sits on the calendar 180 days out.
What today costs
Miss a date here and the consequence is legal.
Late rent is money that arrives later. A lapsed certificate is a rent increase you are not allowed to ask for, a letting you may not be allowed to continue, and a tenant who can leave without notice.
The certificate that lapsed in a drawer
An EPC runs ten years. It expires once per owner per decade, on a date written inside a document nobody has opened since the day it was filed.
The increase that cannot be sent
In Brussels an expired energy certificate blocks indexation outright. Not reduced, blocked, until a surveyor has been out and issued a new one.
The lease registered two days late
Belgium gives the landlord two months from signature. The fine is small. The real sanction is that a tenant on a nine-year lease can then walk out with no notice and no indemnity.
How it works
It works backwards from the date, not forwards from a reminder.
An alert on the day a certificate expires is a report of a failure. The useful moment is the one where somebody can still be booked, and that moment sits a different distance from the date for every certificate.
- Step 1
The rule pack says what applies
Which certificates your region requires, how long each stays valid, and which of them this building actually needs. Six packs ship with it, and Belgium is three of them.
- Step 2
Each one gets its own lead time
180 days for an EPC, 365 for an electrical inspection, 45 for a boiler or a chimney, 14 before a lease registration falls due. The interval is statutory, the lead time is practical.
- Step 3
The alert opens, and booking starts
Dardaris asks for quotes, offers the tenant slots and books the trade. Routine work goes ahead. Anything above your cap is prepared and left on your desk.
- Step 4
The new document is filed
Against the unit or the building it certifies, with its issue and expiry dates read off it, and the next date set from there. No calendar to keep in step.
One certificate, from issue to replacement
An EPC is issued once and then does nothing for ten years, which is exactly why it lapses. Issued 12 March 2016, valid to 12 March 2026. All of the work sits in the last six months, so that is the part drawn below.

A lapsed EPC is not only a compliance problem. It stops you raising the rent. In Brussels an expired energy certificate blocks indexation outright, and it has to be valid at the moment you index rather than merely when the lease was signed. The anniversary passes, the increase does not happen, and no letter afterwards recovers it. How indexation works
What you get
One calendar, six rule packs, and the paperwork where the asset is.
Every certificate on its own clock
An EPC runs ten years, an electrical inspection twenty-five, a boiler and a chimney one. Each carries the lead time it needs rather than one reminder rule stretched over all of them.
How early the alert opens

The interval is the law. The lead time is how long it takes to get somebody out, and it is the part a single reminder rule gets wrong.
Lease registration, tracked to the day
Two months from signature in Belgium, filed by the landlord. Dardaris counts the days from the signature it already holds.
Lease registration, Zandstraat 4
day 46 of 60
Fourteen days out the alert opens, then escalates every day it is still not filed.
A pack per region, not per country
Flanders, Brussels, Wallonia, the Netherlands, France, and a placeholder for anywhere else. Belgium is three because the regions have diverged since 2018, and the pack follows the building, so a Ghent owner with a Brussels flat gets Brussels rules.
Filed where the asset is
The boiler attestation belongs to the unit, the lift inspection to the building. Open either and its documents are there, dated, rather than in a folder named after the year they arrived.
Anything unconfirmed says so
Every rule in a pack is either sourced or flagged. Dardaris shows you what it could not confirm against a primary source and how many such rules a pack still holds, because a guess dressed as settled law is worse than a blank.
Flanders, certificates required to let
The EPC and the electrical report are sourced. Whether an asbestos attest is yet required to let a dwelling is not, so it is flagged rather than acted on.
Where it stops
It books and it files. It does not advise.
Dardaris is not your lawyer, and it certifies nothing itself.
It watches the date, gets somebody out to the property and files what they issue. The certificate is signed by the surveyor, the technician or the registry, never by us. Where a rule could not be confirmed against a primary source it carries a flag, and it stays a flag until you settle it rather than quietly becoming a fact.
Waits for you, every time
- Booking a trade above the spend cap you set
- Anything resting on a rule still marked confirm this
- Submitting a registration or a filing in your name
- Deciding that a certificate does not apply to a building
Everything else it does, and writes down why.
Hand over this part first.
