District cooling and chiller charges in Dubai

What rent premium covers the chiller bill on a chiller-free Dubai letting?

Left of the line the premium does not reach the fixed charge, so it buys no cooling at all. Right of it the headroom buys less than it looks: AED 6,000 a year covers about 1.55 hours a day at full contracted capacity and AED 12,000 about 7.06, both against a consumption the tenant now chooses and no longer pays for.

The rule

Ask what a chiller bill costs in Dubai and you are given a range. Ask what decides it and the answer is usually "how much air conditioning you use", which is wrong in the way that matters: most of the bill is settled before the tenant touches the thermostat.

There are three instruments behind this, and all three are published. They say what the bill is made of, what a provider may and may not charge, and what the provider owes an owner whose meter is broken. None of them appears on a competing page, and the one figure every competing page prints turns out to be the smaller half of the bill.

The definition that decides everything

The tariff is not a price for cooling. Article 11(a) of Executive Council Resolution No. (6) of 2021 sets the basis: "The tariff for District Cooling Services provided to Customers will be calculated on the basis of Cooling Capacity". Capacity, not consumption.

The Regulatory and Supervisory Bureau's RD10 turns that into two definitions. The capacity tariff is "the unit charge normally quoted in dirhams per year for each refrigeration-ton of cooling capacity". The capacity charge is "the multiple of Capacity Tariff and Contracted Capacity normally applied on a monthly basis".

Read that second definition slowly, because the whole page follows from it. Consumption is not in it. Occupancy is not in it. The thermostat is not in it. It is a rate times a quantity fixed by contract, billed every month, and the only thing a resident can do about it is nothing.

The consumption charge sits alongside it: the consumption tariff times metered refrigeration-ton-hours. That is the part the tenant controls, and it is the part everyone writes about.

Who pays depends on one definition. ECR 6 of 2021 defines the Customer as "The beneficiary of a District Cooling Service with whom the relevant service contract is concluded". Not the owner by default and not the occupier by default: whoever holds the contract. That is why "chiller-free" is a letting decision rather than a building feature, and it is the decision this page prices.

What a provider may charge, and what it may not

RD10 is a closed list. Section 1 says: "Only the tariffs, charges and fees expressly identified and authorised in this RD shall be permitted." ECR 6 of 2021 puts teeth behind it twice. Article 12(b) says "No Permit Holder may collect from a Customer any charges or tariffs for the services it provides" unless the Supreme Council of Energy has approved them, and Article 15(b) sets the ceiling on the consequence: "A fine must not exceed two hundred thousand dirhams (AED 200,000.00)".

So the useful question is not what the charges are called but whether each one is on the list, and with what ceiling.

Three of those rows are worth more than the rest.

The capacity tariff may not escalate. RD10 is explicit: "Tariff arrangements that include indexation or escalation of Capacity Charges will not be approved." A capacity charge that has climbed year on year is not an inflation adjustment; it is something to ask the provider to explain against that sentence.

Late payment fees stop. The regulation caps the accumulation, not just the instalment: "the total accumulated Late Payment Fees at any time shall not exceed one hundred percent (100 %)" of the charges outstanding. A balance cannot be doubled twice.

The deposit is a known number. Eight months of capacity charges, which at five refrigeration tons and the published tariff is AED 2,500, computable in advance rather than discovered at handover.

The consumption cap has nothing in it but the fuel surcharge

Empower publishes its rates, which makes it the one place a Dubai consumption tariff can be read rather than estimated. Its consumption charge is "at a rate of AED 0.568 fils per RT per hour".

Set that beside RD10's cap of 0.643, which is inclusive of the fuel surcharge, and subtract. What is left is 0.075, which is RD10's separate cap on the fuel surcharge, exactly.

That is not a coincidence worth admiring; it is a fact worth using. The ceiling was set at the base rate plus a full surcharge and left no other room. So a consumption rate above 0.643 is above the cap and unapproved, and a consumption rate at 0.643 is a base rate carrying the maximum surcharge the Bureau will allow. There is no third explanation.

The floor: a year in which the flat is never cooled

Empower's capacity charge is "at the rate of AED 750 per Refrigeration Ton (RT) per annum, billed monthly in advance", and meter maintenance: "This is charged quarterly at the rate of AED 50 for 3 Months or AED 30 per month". Both are charges on the account, not on the cooling.

Contracted capacity is set building by building and this page does not pretend to know it, so here is the standing cost across the range a Dubai one bedroom plausibly carries. Every figure is the capacity charge plus twelve months of meter maintenance plus VAT at 5%, and nothing else at all.

On the illustrative one bedroom this site prices throughout, 900 sq ft at AED 1,500,000 with AED 105,000 of rent, a five-ton allocation costs AED 4,315.50 a year before a single refrigeration-ton-hour is metered. That is 4.11% of the gross rent and 0.27 points of net yield on the full cash outlay computed by the net rental yield page. That is the cost measured in points, not a correction to that page's figures: the illustrative unit there is modelled as one where the tenant holds the cooling account, which is the usual arrangement and the reason the charge is so often left out of a yield entirely.

Expressed the way the other large running cost is expressed, it is AED 4.79 per square foot per year, against a service charge of AED 18. A reader who has carefully checked the approved service charge on the Service Charge Index and stopped there has checked about four fifths of the building's fixed cost and missed the rest.

Does it stop when the flat is empty?

Neither regulation says. RD10 has no vacancy provision and RD06 has none either, which is itself the answer: there is no relief in the rules because the charge was never contingent on use.

The provider says so directly. Empower's charges page, on voluntary disconnection, states that "Demand Charges and Meter Maintenance Fee will be continued to be charged irrespective of the property is disconnected", and charges "at a charge of AED 150 per instance" for the disconnection itself.

So at five tons a flat standing empty accrues AED 359.63 a month, or AED 1,078.88 over a three-month void, and switching the service off makes it worse by AED 150 rather than better. This belongs in the fixed-cost line of a break-even occupancy calculation beside the service charge, for exactly the same reason: it is payable whether or not anybody is paying rent.

What a chiller-free premium actually buys

A chiller-free letting moves the contract, and therefore the whole bill, to the landlord. The rent premium is the landlord's entire compensation for a cost whose fixed part they cannot avoid and whose variable part the tenant decides.

Rather than guess at a tenant's consumption, solve for it. Given a premium, the break-even is the consumption at which the landlord is exactly whole: the premium less the standing cost, divided by the consumption tariff with VAT. Residential rent is outside the scope of VAT; the chiller bill is not, which is why the comparison is against the VAT-inclusive cost.

At five refrigeration tons and the published rates:

The first row is the finding. A premium of AED 4,000 does not reach the standing cost, so it buys the tenant nothing: the landlord has given a rent discount of AED 315.50 and called it a premium. The break-even premium, below which a chiller-free listing is strictly worse than letting the tenant hold the account, is the standing cost itself: AED 4,315.50 at five tons, and the table above gives it at four, six and seven.

Above that floor the premium buys surprisingly little. AED 6,000 a year buys about 1.55 hours a day of full-load cooling. AED 10,000 buys 5.22 hours, a load factor of under 22%. Those last two columns are the point of doing it this way: they are dimensionless, so a landlord can check them against a past bill rather than against a rule of thumb, and a landlord who cannot find a past bill has just learned what to ask the seller for.

The asymmetry is the thing to carry away. The premium is negotiated once, against a typical summer; the consumption is chosen every day by somebody who is no longer paying for it. A fixed premium against an uncapped variable cost is a position, not a product, and it should be priced against a heavy user rather than an average one.

Three rights on the bill itself

RD06 governs what arrives each month, and it contains obligations an owner can hold a provider to.

A broken meter is the provider's problem, not a licence to estimate indefinitely. RD06 allows estimated bills for up to two billing cycles after a sub-meter fault. After that, if the meter has not been repaired or replaced, the billing provider "may not include Consumption Charges, estimated or otherwise, in any bill until the Sub-Meter is repaired or replaced". Not a reduced charge. None.

The bill is monthly and the deposit comes back. Billing material "must be issued monthly", in English and Arabic, and the bill must show the deposit held, "which must be returned within 5 working days of concluding the service".

A meter test is free if you are right. On a master-meter test by an independent third party: "If the Master Meter is found to perform within a 3% tolerance, the Customer shall bear the expense of the test." Outside tolerance, the provider pays. That is a priced bet with a published threshold, which is more than most billing disputes offer.

Two more lines decide what may appear on a unit bill at all. Common-area cooling "must be billed directly to the District Cooling Service Provider's Customer", which puts it in the building's service charge budget rather than on an owner's chiller account, and the budget is the thing RERA has to approve under Law No. (6) of 2019, as the service charge page sets out. And building-inefficiency penalties stay where they belong: "Inefficient Building Penalties may not be applied in the bills charged to Units under any circumstances."

The overcharge you can actually identify

RD10 Section 6 governs how a building's capacity is pushed down to its units, and it forbids three things. A provider may not charge more than a unit's allocated share, may not allocate inconsistently, and may not do the thing that is easiest to do: "assigning Contracted Capacity to Units based on installed equipment capacity rather than appropriate allocation".

That matters because installed equipment is the obvious basis. A unit with a larger fan coil looks like it should carry more capacity. RD10 says the allocation must follow the unit's share of the building's contracted capacity instead, and an owner who is told their capacity was set from the plant in their ceiling has been told the method the regulation names as improper.

It is a checkable question with a short form: what is this building's contracted capacity, what is my unit's allocated share of it, and how was that share derived? Three answers, and the third is the one that tests the first two.

What to do before the offer, and before the tenancy

Before buying, ask for twelve consecutive months of chiller bills, not a summer month and not an average. From those, read the capacity charge straight off, because it is the same every month, and keep the consumption range rather than the mean. Ask for the building's contracted capacity and the unit's allocated share. Then put the standing cost into the yield as a fixed cost, where it changes the net by about a quarter of a point on the illustrative unit, and put the consumption range into the calculator as part of what the tenant pays, or does not.

Before letting chiller-free, compute the floor from the table above and refuse a premium below it. Above the floor, convert the premium into hours a day at full capacity and check that number against the bills the seller provided. If the premium buys fewer hours than the flat historically used, the premium is a discount wearing a better word.

Every instrument cited on this page is listed, with what it sets in its own words and a link to its official text, on the Dubai property law register.

The arithmetic

Where it breaks

• Reading a headline rate as the bill. The capacity charge is set by contracted capacity, not by use, so two identical flats in the same tower, with the same thermostat setting, pay different standing costs if their allocated capacity differs.
• Treating a chiller-free premium as income. It is compensation for a cost with a fixed part the landlord cannot avoid and a variable part the tenant decides, and the premium is almost always negotiated against an average rather than against the tail the landlord is actually carrying.
• Assuming the bill stops when the tenancy does. The provider's own charges page says 'Demand Charges and Meter Maintenance Fee will be continued to be charged irrespective of the property is disconnected', and neither regulation contains a vacancy provision at all.
• Paying a capacity charge allocated by the size of the plant above the ceiling. RD10 lists 'assigning Contracted Capacity to Units based on installed equipment capacity rather than appropriate allocation' among the things a permit holder may not do.
• Accepting a capacity charge that rises every year. 'Tariff arrangements that include indexation or escalation of Capacity Charges will not be approved', so an escalating capacity charge is a question for the provider rather than a fact of life.
• Paying a consumption charge while the meter is broken. Where a faulty sub-meter has gone unrepaired for two billing cycles, the billing provider 'may not include Consumption Charges, estimated or otherwise, in any bill until the Sub-Meter is repaired or replaced'.
• Letting common-area cooling onto a unit bill. RD06 says it 'must be billed directly to the District Cooling Service Provider's Customer', which means it belongs in the building's service charge budget and not on an owner's chiller account.

When to use it

Before making an offer on any apartment served by a district cooling plant, because the standing part of the bill is a fixed cost and belongs in the yield before the offer rather than in the first bill after it. Then again before advertising a unit as chiller-free, because that decision moves a variable cost the landlord does not control onto the landlord.
