2027 may still feel far away, but inspection deadlines are worth putting in order before you start planning budgets, shutdowns, and holidays. If you miss a deadline somewhere, you risk trouble during an inspection from the Labour Inspectorate (SÚIP) or the fire brigade. And if damage occurs, a missing inspection can also complicate dealings with your insurance company. Here’s a clear table and a process for creating a plan that will hold up throughout 2027.
Quick orientation: in an office, electrical inspections are usually tracked in a 5-year interval; in production, 3 years; in wet or corrosive environments, 1 year. Fire extinguishers are checked every year. If several regimes apply to one building, use the shortest interval.
Comprehensive inspection interval overview table
Before you start digging through protocols, take a look at what actually needs to be addressed and how often. This is a summary of obligations that apply to most companies in the Czech Republic.
| What is inspected | How often | According to |
|---|---|---|
| Electrical installation | By environment: 5 years (offices), 3 years (manufacturing, schools, hotels, healthcare), 2 years (assembly spaces over 200 people), 1 year (wet operations, permanent corrosion). For environments with fire or explosion hazard 3 years. | Government Decree No. 190/2022 Coll., ČSN 33 1500 |
| Lightning protection system (LPS) | Complete inspection: 2 years (LPL I and II – chemicals, hospitals, explosive atmospheres) or 4 years (LPL III and IV – standard commercial buildings, manufacturing). Visual check every year for all classes. | ČSN EN 62305 ed. 2 |
| Photovoltaic (PV) system | Electrical part according to building regime (typically 5 years, shorter in risk environments). Lightning protection part according to LPS class (2 / 4 years). | ČSN 33 2000, Government Decree 190/2022 |
| Appliances and tools | Approximately from 3 months (construction sites, outdoors) up to about 2 years (offices). Exact intervals are determined by the usage group and appliance class. Subsequent check at least 1× every 12 months. | ČSN 33 1600 ed. 2, Government Decree No. 378/2001 Coll. |
| Fire extinguishers | Operational check 1× per year. Periodic pressure vessel test: 3 years (water, foam), 5 years (powder, CO₂). | Decree No. 246/2001 Coll. |
| Fire safety equipment (fire alarm, smoke extraction) | Operational check 1× per year. The manufacturer can only shorten the interval, not extend it. | Decree No. 246/2001 Coll. |
| Fire safety training | Employees 1× every 2 years, managers 1× every 3 years (in case of increased or high fire hazard). | Decree No. 246/2001 Coll., Act 133/1985 Coll. |
| Occupational health & safety (OHS) training | The law does not set a fixed interval. Frequency and content are determined by the employer based on risks. In practice, an interval of 1 to 3 years has proven effective. | § 103 of the Labour Code |
One golden rule applies to the entire table: the manufacturer or supplier can always only shorten the interval, never extend it. And another – if your building is subject to multiple intervals from different categories (e.g., manufacturing in a wet operation), the shortest one always applies.
More detailed analyses, including exceptions, can be found in articles about electrical installation inspections, lightning protection system inspections, PV system inspections, appliance (PAT) testing, and fire safety.
How to create an inspection plan for 2027
With the table in hand, it will go quickly. Here are five steps to ensure you don’t miss anything.
- ① Make an inventory of equipment and spaces. List everything you have: electrical switchboards, lightning protection system, PV panels and inverters, appliances and tools, fire extinguishers, smoke detectors, emergency lighting. Don’t forget outdoor warehouses, workshops, or driveway gate drives.
- ② Determine the environment and class for each item. This determines the interval. A dry office is inspected differently than a woodworking shop with dust. You can find the classification in older inspection reports or in the project documentation. If you are unsure, have it assessed by a certified electrical inspector.
- ③ Find the date of the last inspection from the protocol. Each report has a date of execution. The next deadline is derived from it. File the protocols in one place – ideally digitally.
- ④ Calculate the next deadline and enter it into the calendar in advance. You want to book the certified electrical inspector before the interval expires. Set a reminder at least two months ahead. During the season (spring, autumn), inspectors tend to be busy and waiting times increase.
- ⑤ Maintain one matrix or register. A table with rows for individual devices and columns for deadlines, environment classes, and supplier contacts will save you stress during a random check. And most importantly – you won’t have to dig through papers every time wondering, “when was it actually last done.”
Common mistakes in the inspection plan
Even a well-intentioned plan can fail on the details. We see these mistakes repeatedly in companies.
- Relying on someone else to track the interval. An external technician performs the inspection and moves on. You must track the next deadline yourself. If your supplier does this for you, you’re lucky – but verify it.
- Overlooking that one building is subject to multiple intervals. A classic: a manufacturing hall with a wet operation. According to the manufacturing environment, 3 years would suffice, but the wet operation reduces the interval to 1 year. The shortest one always applies, so 1 year.
- Confusing a check and an inspection. For example, with fire extinguishers: an annual operational check is not enough. A periodic pressure test by a specialized company must be carried out every 3 or 5 years. For appliances, a subsequent check supplements the periodic inspection and only replaces it in specific cases – details can be found in the detailed article on appliances.
- Expired inspection during an insurance claim. When a valid inspection is missing after a fire or other damage, the insurance company may proportionally reduce the payout – but only if the missing inspection had a demonstrable influence on the cause or extent of the damage. It is not an automatic rejection. More in the article about inspections and insurance.
- Unclear responsibility in a lease. Building owner and tenant – who orders the inspection? The answer is in the lease agreement, not in the technical standard. If the contract is silent, responsibility generally falls on the owner – but you don’t want to rely on that.

Frequently asked questions
How often is an electrical installation inspection in an office?
According to Government Decree No. 190/2022 Coll. and ČSN 33 1500, it is once every 5 years – assuming it is a standard administrative environment without increased humidity, dust, or vibrations.
How often is a lightning protection system inspection?
It depends on the LPS class. Standard commercial and manufacturing buildings (LPL III and IV) – every 4 years complete inspection. Hospitals, chemical operations, and explosive atmospheres (LPL I and II) – every 2 years. Additionally, a visual check once a year applies to all classes. Details in the article on ČSN EN 62305.
What if a building is subject to multiple intervals?
The shortest one always applies. If you have a manufacturing operation (otherwise 3 years) that is also an assembly space for more than 200 people (2 years), you inspect every 2 years. If a wet environment also comes into play, it’s every 1 year.
Does anyone track the intervals automatically?
No. Unless you have a supplier who does this as part of their service, you must track the deadlines yourself. The protocol from the last inspection sits in your drawer – and you cannot explain to authorities or the insurance company that you simply forgot.
Is one inspection enough for peace of mind?
Unfortunately not. Inspections are repeated at intervals set by law or standard. Moreover, conditions in the operation can change – a machine is added, the environment changes, the installation ages. An inspection is a regular process, not a one-time sticker.
What the article is based on
The intervals in the article are based on these regulations and standards (regulations verified against the official e-Sbírka, intervals according to valid ČSN):
- Periodic electrical installation inspections by environment: Government Decree No. 190/2022 Coll. (Annex No. 4) and ČSN 33 1500.
- Lightning protection system (LPS) inspections by lightning protection level class: ČSN EN 62305 ed. 2.
- PV system inspections: ČSN 33 2000 and related standards; electrical installation intervals according to Government Decree No. 190/2022 Coll.
- Inspection and testing of electrical appliances and tools: ČSN 33 1600 ed. 2 (amendment Z2) and Government Decree No. 378/2001 Coll. (§ 4).
- Fire extinguisher and fire safety equipment checks, fire safety training: Decree No. 246/2001 Coll. (§ 7, § 9, § 23) and Act No. 133/1985 Coll. (§ 16).
- OHS training: Labour Code (Act No. 262/2006 Coll.) (§ 103) – the law does not set a fixed interval; it is determined by the employer based on risks.
The specific interval always depends on the environment, class, and type of equipment; if multiple apply, the shortest one is valid. The manufacturer’s accompanying documentation can only shorten the interval. Regulations and standards may change – the article is an indicative overview, not a substitute for an assessment of a specific operation.
