How managing agents process utility bills, and where errors creep in

A managing agent with a few hundred buildings can receive thousands of utility bills a year: landlord electricity for corridors and lifts, gas for communal boilers, water for the estate. Each one has to be placed against the right building, coded to the right fund and heading, and posted for the right period.

Utility bills look routine, so they get less attention than a large repair invoice. They also cause a surprising share of the corrections at year end. Here is how agents usually process them, and the six places errors creep in.

How utility bills are usually processed

The steps are the same at most agents, whether they are done by hand or with software:

• The bill arrives by email, through a supplier portal or by post.

• Someone works out which building it is for, usually from the supply address or the meter number.

• They take the amount for this period and check the VAT and Climate Change Levy.

• They code it to the building’s service charge fund, the right schedule and the utilities heading.

• It is approved under the client’s rules and posted to the property ledger.

• At year end, bills not yet received are accrued so the accounts cover the whole year.

1. Taking the wrong total

A single page can show current charges, a balance brought forward, an instalment amount and a payment slip. The largest figure is often the account balance, which includes last period’s charges. Post that figure and the previous period is in the accounts twice.

The check is simple to describe and tedious to do by hand: take the current charges, and confirm that net, VAT and total agree with each other.

2. Placing the bill against the wrong building

Utility bills are often addressed to the managing agent or the RMC, at the agent’s office. The clue to the building is the supply address, and on a large estate several supplies can share a street name and a postcode. The meter number is the most reliable key, so it is worth holding meter numbers against each building in your records.

3. Estimated reads and the wrong period

An estimated bill is a real invoice, but the consumption on it is a guess, and the next actual read will correct it. If an estimate and the later correction land in different service charge years, one year carries cost that belongs to the other. Recording the billing period and whether each read was estimated or actual makes this visible before year end.

4. VAT and Climate Change Levy

Whether a supply is billed as domestic or non-domestic decides both the VAT rate and whether Climate Change Levy applies. Non-domestic supplies carry VAT at the standard rate and the levy. Supplies within HMRC’s de minimis limits, 1,000 kWh a month for electricity and 4,397 kWh a month for gas, are treated as qualifying use, with the reduced rate and no levy. The rules are in VAT Notice 701/19.

Rates are moving this winter as well. From 1 October 2026 to 31 March 2027, electricity for qualifying use in Great Britain is temporarily zero rated, and a bill spanning 1 October may split the VAT by date. When the rate on a bill changes from one period to the next, it is worth a look, and it is easy to miss when bills are keyed by hand.

Where the VAT on a bill cannot be recovered by the client, it is a cost to the service charge, so an incorrect VAT figure flows straight into what leaseholders pay.

5. Duplicates and credit notes

Suppliers send the same bill by email and post, send a reminder that looks like a new bill, or reissue a bill after a meter correction. Each one can be posted twice. Credit notes after a correction are just as easy to miss, and a missing credit is money the building is owed.

6. Bills that arrive late

Some utility bills arrive months after the period they cover, especially after a change of supplier or a disputed read. At year end, the accounts need an accrual for supply used and not yet billed. An up-to-date record of the last billed period for each supply turns that into a short list.

The checks that catch most of it

• Take the current charges only, and check net, VAT and total agree.

• Match on meter number and supply address, using records held against each building.

• Record the billing period and whether each read was estimated or actual.

• Compare the VAT rate and Climate Change Levy with the last bill for the same supply.

• Check for duplicates on supplier, account, period and amount, and look for expected credit notes.

• Keep the last billed period for each supply, for accruals at year end.

Every check on that list is repeatable, which makes utility bills a good place to start with automation. The decisions that need judgement, such as whether a disputed bill should be paid, stay with your team.

Automating utility bill processing

Our utility bill processing for property managers reads electricity, gas and water bills with supplier-specific layouts, takes the figure that belongs to the invoice, checks net, VAT and total, and codes each bill to the property, fund and heading before posting to MRI Qube or exporting for Blocks Online. Anything uncertain is held for your team with the reason named.
