The energy certificate on a shell-form property, and why it changes when you finish it

Most people buying in Malta receive an Energy Performance Certificate somewhere in the paperwork before the promise of sale, glance at it, and file it. On a finished apartment that is a reasonable response. On a shell it is not, because the document you have been handed may be describing a building that does not yet exist — and the obligation to produce a second one, later, falls on you.

The law requires a certificate before the promise of sale

An EPC is required on the construction, sale or rental of a building, and it must be handed over before the promise of sale. It has to be issued by an independent energy performance of buildings assessor registered with the Building and Construction Authority — regulation 14(2). Not the developer, not the architect who drew the plans in that capacity, not the agent.

The regulations also reach into marketing. Regulation 13(5) requires the energy performance indicator to be stated in advertisements offering a property for sale or rent. That obligation will be yours when you eventually sell or let the finished property.

And if nothing arrives: regulation 14(5) lets the buyer commission the certificate and deduct the cost. That is a real remedy, not a technicality, and it is worth knowing before you accept "we'll sort it out at the contract".

A shell has nothing to rate — so the law rates the design instead

Here is the problem the regulations are solving. An energy certificate assesses how a building performs in terms of heating, cooling, ventilation, hot water and lighting. A shell has none of those. It has concrete, blockwork, openings and, if you are fortunate, a screed. There is no air conditioning, no water heater, no lighting, often no apertures.

So S.L. 623.01 defines two different ratings:

• A design rating is calculated at design stage, on the building taken as complete — with the permanently installed finishes, fixtures, fittings and mechanical and electrical services needed to make it habitable. It is a projection of the building someone intends to produce.
• An asset rating is based on the building as actually constructed.

Regulation 14(4) sets the test for which one you get: the certificate handed over before the promise of sale is on the design rating if the building is not yet constructed and finished, and on the asset rating if it is.

Read that test carefully. It is not "shell versus finished". It is "constructed and finished". A property can be structurally complete and still fail the second limb. Equally, do not assume that because you are buying a shell you must have been given a design rating — check the certificate you actually received and see which rating it states. That one word on the document determines whether anything further is required of you.

The design was somebody else's assumption

If what you hold is a design rating, it was calculated on an assumed finished building: assumed glazing, assumed insulation, assumed heating and cooling equipment, assumed water heating, assumed lighting. Those assumptions were made by whoever commissioned it, for a building they were not going to finish.

You are now going to finish it, and you will make your own choices. Different apertures. A different air conditioning configuration. A heat pump instead of an electric cylinder, or the reverse. Insulation where none was drawn, or none where some was drawn. Each of those decisions moves the actual building away from the designed one.

Regulation 15(4): the second certificate

This is the clause that converts the certificate from a seller's formality into part of your finishing job.

Where the construction or the mechanical and electrical installation differs from the design on which a design-rating EPC was obtained, a new EPC based on the asset rating must be secured by the owner, before the building is used.

Three things in that sentence matter to a buyer finishing a shell:

1. The duty is on the owner. By the time the as-built differs from the design, the owner is you. The developer's obligation ended at the promise of sale.
2. The trigger is difference, not amount. The regulation speaks of construction or M&E installation differing from the design, without a tolerance.
3. The deadline is "before the building is used" — not before you sell it, and not at some later renewal date. It sits at the end of the finishing programme, alongside the other things that have to be in place before you move in.

Practically, this means the assessment belongs in your schedule rather than in your conveyancing file. It also means the specification decisions you take during finishing — glazing, insulation, the heating, cooling, ventilation, hot water and lighting systems — are the same decisions the asset rating will later be calculated on. The regulation does not tell you what to choose. It does tell you that what you choose gets measured.

Ten years, and what resets it

Regulation 15(1) gives a certificate ten years' validity. The exception is a major renovation, which the regulations define by threshold: works affecting 25% or more of the volume of the building, or 25% or more of its windows, roofs or external walls.

A certificate also comes with a recommendation report. It is advice, not an instruction, but it is the document that tells you what the assessor considered weak in the building as rated.

Exemptions

Regulation 14(6) exempts certain buildings from the certificate requirement. Two are relevant to buyers here:

• Grade 1 and Grade 2 scheduled buildings, where compliance would unacceptably alter their character. If you have bought a scheduled townhouse, this may apply — but it is a conditional exemption, not an automatic one, and the condition is about character.
• Stand-alone buildings with a useful floor area of less than 50 m².

Note that this is an exemption from the certificate, not a general exemption from anything else. Planning Authority permits, condominium rules on works affecting common parts, and every other obligation on a Maltese finishing project are untouched by it.

What to do with this

1. Find the certificate from your promise of sale and read which rating it states — design or asset.
2. If it is an asset rating, it describes a building that was constructed and finished. If you then finish or substantially alter it further, revisit the position.
3. If it is a design rating, assume a second certificate is coming at the end of your works, and find out what the design assumed so you know when you have departed from it.
4. Keep the specification record of apertures, insulation, and the heating, cooling, ventilation, hot water and lighting equipment actually installed. That is what the asset-rating assessment describes.
5. Appoint a registered independent EPB assessor for the as-built certificate, before the property is used.

The honest summary: on a shell, the energy certificate is not a document the seller dealt with on your behalf. It is a document that was issued about a building nobody had built yet, and finishing that building is what makes it inaccurate.
