Sliema and Mriehel offices: Class 4A and occupancy cost

Two quotes on the desk. A seafront floor in Sliema and a corporate plate in Mriehel, and the headline rents are close enough that the decision looks like a matter of taste. It usually is not, because the two numbers are measuring different things.

Start with the one thing that is identical in both places. The use you need is Class 4A under the Development Planning (Use Classes) Order, S.L. 552.15, covering financial, professional and comparable offices. Not a dwelling, not a shop, not a cafe. After that the two locations diverge sharply, and most of the divergence sits outside the rent line: service charges, parking, metered utilities and the cost of getting a circuit into the building. Live Class 4A stock is on offices in Malta.

Class 4A means financial, professional and comparable

Class 4A is the office class. It covers financial services offices, professional offices and other offices of a comparable nature, which in practice means consultancies, accountancy floors, law practices and back-office operations for licensed firms. What it is not is a catch-all for any space someone intends to put desks in.

A dwelling is not Class 4A. A Class 4B shop is not Class 4A. A cafe sits in a catering class of its own. If the permit on that Sliema floor says residential or retail, the word office in the listing does not fix it. Changing the class requires development permission, with everything that follows from that process. Our guide to commercial use classes maps the whole set.

Ask for the permit reference and the approved drawings before you compare rents, not after you have shortlisted. The class has to cover the activity you will genuinely run, including any public-facing counter, which is not an office use no matter where you put it.

Sliema is priced as a residential belt

The NSO locality index for 2025, published on 6 August 2026, puts Sliema at 160.98 and St Julians at 157.43, against 103.55 for apartments in the Malta region. The series is scaled so the national average for the year is 100, and penthouses are excluded.

Those are apartment figures, so they tell you about the neighbourhood you are putting staff into rather than what a Class 4A floor should cost. Converting 160.98 into an office rent, or using it as a yield, produces a number with nothing behind it.

What the index does explain is pressure. Sliema offices compete directly with residential conversion, with seafront amenity pricing and with genuinely scarce parking, and staff housing occupies the same postcode. A landlord who could sell or let the floor as apartments is not going to price it like a business park. That is the reason a comparable headline rate in Sliema tends to leave more cost sitting outside the rent.

Mriehel gets called the CBD, and that is a market line

Operators describe Mriehel as the central business district. Treat that as a market description, because it is not a Planning Authority designation and it is not an NSO series. It also means the Sliema apartment index has no application there whatsoever.

What Mriehel actually offers is an inland office and industrial estate: larger floor plates, purpose-built cores, and parking that comes as part of the product rather than as a daily hunt along the front. The commute is different and the staff conversation is different.

The Class 4A test, though, does not move. A warehouse plate in Mriehel does not become an office because somebody installed a meeting table, and a Sliema maisonette with desks in it is not Class 4A because the listing suggests it is ideal for professionals. Read the permit in both places.

The headline rent is rarely the occupancy cost

Get the class right in both locations and the conversation moves to money, specifically to what the headline rent leaves out. Commercial office quotes in Malta are, as a matter of market practice, a rate per square metre exclusive of VAT and exclusive of common-area maintenance. There is no statutory cap on service charges anywhere, because CAM is a contractual matter governed by the lease and the building rules rather than by S.L. 552.15. Ask for the schedule in writing, and treat reluctance to provide one as information in itself.

Line	Usual market practice	What to get in writing
Headline rent	Quoted excluding VAT and excluding CAM	The rate, the area basis, and whether VAT is added
CAM or service charge	Custom, with no statutory cap	What it covers, how it is apportioned, how it escalates
ARMS and utilities	Often metered to the floor rather than bundled	Separate meters, or the apportionment method
Parking	Frequently a separate line, particularly in Sliema	How many spaces, exclusive or shared, and at what rent
Fibre and risers	The building may provide a riser, not your circuit	Who contracts, who pays, and the lead time to go live

CAM commonly covers security, common HVAC, lifts and exterior cleaning. It does not automatically cover power to your floor, your own air-conditioning plant, or parking.

Put those lines side by side and the comparison often reverses. A Sliema mixed block can look inexpensive on rent and considerably less so once the condominium charge, two parking spaces and a separately metered ARMS bill are added. A Mriehel park can look dearer on the face rate and cheaper once parking and plant turn out to be inside the building offer. Add the same lines to both quotes, or you are not comparing rents at all.

How to run the comparison

1. Confirm Class 4A on the permit for the activity you will actually carry out.
2. Break each quote into rent, VAT, CAM, ARMS, parking and connectivity.
3. Get the CAM schedule in writing. There is no legal ceiling, so the document is the only protection.
4. Use the NSO apartment index as neighbourhood context for Sliema and St Julians only, and never as an office price or a Mriehel benchmark.
5. Walk the commute and the parking as an operator would, at the time of day your staff will actually arrive.

QLC brokers the building and the commercial terms. The architect and the Planning Authority own the Class 4A position on the floor, and that is the part worth confirming before anything else.

Frequently asked questions

What is the difference between renting an office in Mriehel and in Sliema?

Sliema is a high-cost residential and seafront belt, while Mriehel is an inland office and industrial estate with larger plates and parking built in. The Class 4A requirement is identical in both. What differs is everything sitting around the headline rent.

Are service charges included in Malta commercial rents?

Usually not. Headline rent is typically quoted exclusive of VAT and of common-area maintenance, and service charges are contractual with no statutory cap.

What does a Class 4A permit cover?

Financial, professional and comparable offices under S.L. 552.15. It does not by itself convert a flat or a shop into an office.

Is Mriehel officially the Malta CBD?

No. That is a market description rather than a Planning Authority or NSO designation.

Can I use the NSO apartment index to price a Sliema office?

No. Sliema at 160.98 and St Julians at 157.43 are residential index values against a national average of 100, with the Malta region at 103.55. None of them are office prices per square metre.

Does a Sliema Class 4A floor include parking?

Frequently not. Parking is commonly a separate commercial line, so count the spaces and cost them on both quotes before deciding.

This article is general information rather than planning or leasing advice. Class 4A depends on the approved drawings and on the exact activity, and service charges are a matter of contract rather than statute. Have a Maltese perit read the permit before you sign.
