Metering Electricity and Water per Pitch: From Reading to Invoice

Across Europe, many campsite operators lose a significant share of their electricity revenue to flat-rate billing models that reward heavy users at the expense of moderate ones. The solution is straightforward in principle but surprisingly underused in practice: metering that measures consumption at each individual pitch and charges guests only for what they actually use. This article explains why per-pitch metering matters, how the technology works, what practical considerations apply, and how operators can implement a fair, cost-transparent billing system.

Key Takeaways

• Flat-rate electricity pricing at campsites creates unfair cost distribution and reduces operator revenue.
• Per-pitch metering enables accurate, consumption-based billing for every guest.
• Modern metering systems combine smart meters, remote monitoring, and automated billing software.
• A well-implemented metering system recovers revenue and reduces disputes over time.
• The same principles apply to water metering, allowing operators to bill both utilities fairly.

Why Flat-Rate Electricity Billing Is a Problem for Campsites

For decades, many campsites have bundled electricity into the pitch fee or charged a fixed daily supplement. On the surface, this seems simple. In reality, it creates significant imbalances.

The heavy-user problem: A motorhome running an air conditioning unit, a refrigerator, a coffee machine, and an electric heater can consume far more electricity per day than a tent camper with only a phone charger. Under a flat-rate model, both pay the same. Light users effectively subsidise heavy users.

Revenue leakage: As electricity prices have risen sharply in recent years, the gap between what operators pay their utility and what they recover from guests has widened. On a site with many pitches, even a modest daily shortfall per pitch accumulates into a substantial loss across a full season.

Guest disputes: When guests do not know what they are paying for, complaints arise. Transparent, itemised billing reduces friction and builds trust.

What Per-Pitch Metering Actually Means

Per-pitch metering refers to the installation of individual electricity meters at each pitch connection point, also called a service pillar or power pedestal, so that the operator can record each guest's consumption separately and issue a consumption-based invoice.

The concept mirrors the way apartment buildings use sub-metering: a master meter records total site consumption, while individual sub-meters track usage per unit. The operator purchases electricity at a wholesale or commercial tariff and passes on costs to guests at a defined per-kWh rate.

The same approach works for water. By installing water meters at each pitch, operators can bill guests for actual water consumption rather than absorbing the cost or spreading it unevenly through flat fees.

Core Components of a Per-Pitch Metering System

A complete per-pitch metering setup typically includes the following components:

Technologies Used in Modern Metering Systems

Several technology paths exist, each with different cost and complexity profiles.

Wired M-Bus Systems

M-Bus (Meter-Bus) is a European standard for remote reading of utility meters. Wired M-Bus is reliable and accurate, making it a preferred choice for permanent campsite infrastructure. The downside is the cost of cabling, which can be significant on large sites with dispersed pitches.

Wireless and LoRaWAN Systems

Wireless metering using LoRaWAN (Long Range Wide Area Network) or similar protocols eliminates the need for dedicated meter-reading cables. A single LoRaWAN gateway can cover an entire campsite. These systems are increasingly popular for retrofits because they require minimal civil engineering work.

MQTT-Based IoT Integration

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol widely used in IoT applications. Meters and sensors that communicate via MQTT can transmit readings to a central system in near real time. Campsite OS offers IoT connectivity via MQTT as a beta feature, enabling operators to read electricity and water meters and assign consumption data directly to pitch bookings.

Powerline Communication (PLC)

PLC systems transmit meter data over the existing electrical wiring. This is cost-effective for sites where rewiring is impractical, though signal quality can vary depending on cable age and load conditions.

Integrated Power Pedestal Solutions

Some manufacturers now offer service pillars with built-in metering and communication modules. These all-in-one units simplify installation and reduce the number of separate components.

The technology choice should be driven by site layout, existing infrastructure, and the operator's IT capabilities. A small family campsite has very different needs from a large resort.

Practical Considerations for Metering and Billing

Operators who resell electricity or water to guests should be aware of several practical matters.

Meter Calibration

If a meter reading becomes the basis for a charge on a guest's invoice, calibration stops being a technical detail and becomes the thing that makes the charge defensible. Expect suppliers to talk about certification and periodic recertification. What applies to your site, and on what interval, is a question for a qualified adviser or the relevant authority where you operate — clarify it before you buy hardware, not after.

Tariff Transparency

Operators should communicate the per-kWh or per-litre price clearly before guests connect. Hidden charges or retroactive price changes create disputes and erode trust.

Billing and Receipts

Reselling electricity or water means issuing a proper receipt or invoice for it, with the utility charge shown separately from the pitch fee rather than folded into a single total. The invoicing features in Campsite OS support itemised billing that keeps the two apart. How the charge should be treated for tax is a question for your accountant.

Before You Start Reselling

Selling a utility on to guests is not the same as including it in the pitch price, and there may be more to it than buying meters. Clarify what applies to your site with your own advisers or the relevant local authority before the first invoice goes out.

How Per-Pitch Metering Improves Guest Experience

Fair billing is not just an operator benefit; it is a guest benefit too. Modern campers, particularly those travelling with electric vehicles or large motorhomes, are accustomed to transparent utility billing. They expect it.

Transparency Builds Trust

When guests receive an itemised statement showing their kWh or litre consumption and the per-unit price, they understand exactly what they are paying for. This eliminates the suspicion that the campsite is overcharging through opaque bundled fees.

Incentivising Efficiency

Consumption-based billing naturally encourages guests to use electricity and water more efficiently. Guests who know they are paying per unit are more likely to switch off appliances when not in use or take shorter showers. This reduces the campsite's total consumption, which can lower the operator's costs.

Supporting EV Charging Infrastructure

The growth of electric vehicle ownership among campers makes per-pitch metering increasingly important. An EV charging session can add a substantial amount to a single overnight stay. Without metering, operators either absorb this cost or impose blanket surcharges that penalise non-EV guests.

Step-by-Step Implementation Guide for Campsite Operators

Implementing a per-pitch metering system is a project that requires planning, investment, and coordination. The following steps provide a practical roadmap.

Step 1: Audit the Existing Infrastructure

Before purchasing any equipment, map the current electrical and water layout. Identify the number of pitches, the location of distribution boards and water mains, cable and pipe routes, and the capacity of the main supplies. This audit determines whether the existing infrastructure can support individual metering or whether upgrades are needed.

Step 2: Define Billing Goals and Tariff Structure

Decide how consumption will be priced. Options include:

• A flat per-unit rate (simplest to communicate)
• A tiered rate (lower rate up to a threshold, higher rate above it)
• A time-of-use rate (lower rates at night to shift load)

The chosen structure should be clearly communicated to guests at booking and check-in.

Step 3: Select and Procure Metering Equipment

Based on the site audit, choose between wired M-Bus, wireless LoRaWAN, MQTT-enabled IoT devices, or integrated pedestal solutions. Ensure all meters carry the required calibration certification for billing use in the relevant jurisdiction.

Step 4: Install and Commission the System

Work with a certified electrician and, where required, a registered metering point operator. Commission the communication network and verify that all meter readings are being correctly transmitted to the management software.

Step 5: Integrate with Booking and Property Management Systems

Connect the metering platform to the campsite's property management system. This allows consumption data to be automatically assigned to guest stays and included in checkout invoices. Campsite OS supports this workflow through its IoT integration, which reads meter data via MQTT and links it to the corresponding booking. The invoicing module then generates itemised bills that show utility charges alongside pitch fees.

Step 6: Train Staff and Communicate with Guests

Train reception staff to explain the billing model to guests. Provide clear signage at pitches. Consider offering a way for guests to monitor their own usage, such as a display at the pillar or access to a guest portal.

Step 7: Review and Optimise

After the first full season, review the data. Analyse average consumption by pitch type, identify anomalies, and assess whether the tariff structure is recovering costs appropriately. Adjust as needed.

Water Metering: The Same Principles Apply

Everything discussed above for electricity applies equally to water. Many campsites provide water connections at each pitch, and consumption varies widely depending on guest behaviour. A family with young children may use far more water than a solo traveller.

Installing water meters at each pitch allows operators to:

• Bill guests fairly for actual water use
• Identify leaks or unusually high consumption quickly
• Encourage water conservation, which is increasingly important in regions facing water scarcity

Water meters can use the same communication infrastructure as electricity meters. MQTT-enabled water meters, for example, can transmit readings to Campsite OS alongside electricity data, allowing both utilities to appear on a single itemised invoice.

Bringing It All Together with Campsite OS

Campsite OS is a cloud-based application for managing campsites, caravan parks, and holiday parks. You access it through a browser without any local installation. Among its features is a beta IoT module that connects to electricity and water meters via MQTT.

Here is how the workflow looks in practice:

1. Meter reading: Smart meters at each pitch transmit consumption data to Campsite OS via MQTT.
2. Booking assignment: The system matches each meter to the pitch and the current guest booking.
3. Consumption tracking: Reception staff can view real-time and cumulative consumption for any pitch.
4. Checkout billing: At checkout, the system calculates the total utility charge based on the configured per-unit rate and adds it to the invoice.
5. Itemised invoice: The guest receives a clear breakdown showing pitch fees, utility charges, and any other items.

This automation removes manual meter reading from the daily routine, reduces transcription errors, and ensures that every kWh and every litre is accounted for.

The IoT integration in Campsite OS is currently in beta. If you are interested in testing it on your site, you can request a demo to see how it works and discuss your specific requirements.

Cost and Return on Investment

The capital cost of a per-pitch metering system varies widely depending on site size, technology choice, and existing infrastructure. Smaller sites with fewer pitches will naturally have lower total costs than large resorts.

The return on investment comes from several sources:

• Recovered revenue: Consumption-based billing captures revenue that was previously lost to flat-rate pricing.
• Reduced disputes: Transparent billing means fewer complaints and less staff time spent resolving them.
• Lower consumption: When guests pay for what they use, they tend to use less, which reduces the operator's utility bills.
• Operational efficiency: Automated meter reading and billing integration free up staff time for other tasks.

For many operators, the system pays for itself within a few seasons. The exact timeline depends on site size, current pricing model, and guest consumption patterns.

Frequently Asked Questions

What is the difference between a sub-meter and a main meter at a campsite?

The main meter records total electricity or water consumed by the entire campsite and is the basis for the operator's utility bill. Sub-meters are installed at individual pitches to record each guest's consumption separately. The sub-meter readings are used for guest billing, while the main meter reading determines what the operator pays the utility.

Do campsite meters need to be officially calibrated?

Treat it as a yes until someone qualified tells you otherwise: once a reading determines what a guest pays, the meter's certification is what makes the charge stand up. Suppliers will quote certification and recertification intervals. Confirm what applies to your site with a qualified adviser or the relevant authority before you commit to hardware.

Can a campsite charge guests more per unit than the operator pays the utility?

Operators generally add a margin to cover administrative costs, infrastructure maintenance, and metering system amortisation. The resale price should be transparent. Operators should verify any applicable rules with their own advisors.

What happens if a meter malfunctions and records incorrect data?

A malfunction should be reported immediately. Billing should be suspended for the affected pitch until the meter is repaired or replaced. Estimated billing based on comparable pitches may be used as a temporary measure, but guests should be informed. Maintaining a spare inventory of meters reduces downtime.

Is wireless metering as accurate as wired metering?

Wireless metering systems are equally accurate in terms of measurement; accuracy is a function of the meter itself, not the communication method. The communication channel affects data transmission reliability. Reputable wireless systems achieve high transmission success rates in outdoor campsite environments.

How does per-pitch metering support EV charging at campsites?

Electric vehicle charging dramatically increases per-pitch electricity consumption. Without individual metering, the cost of EV charging is either absorbed by the operator or spread across all guests. Per-pitch metering ensures that EV drivers pay for the energy they use, making EV charging financially sustainable for the operator and fair to non-EV guests.

Can I meter both electricity and water with the same system?

Yes. Many communication protocols, including MQTT, support both electricity and water meters. Campsite OS can receive readings from both types of meters and display them in a unified interface, allowing operators to bill both utilities on a single invoice.

What if I only want to meter some pitches?

Partial metering is possible. Some operators start by metering pitches with higher consumption, such as those designated for motorhomes or those with EV charging points, and expand later. Campsite OS can handle a mix of metered and unmetered pitches, applying consumption-based billing where data is available and flat rates elsewhere.

Conclusion

The shift from flat-rate utility billing to per-pitch metering is one of the most impactful operational improvements a campsite operator can make. It recovers revenue, creates a fair and transparent guest experience, and positions the site for the growing demands of EV-owning campers and environmentally conscious travellers.

Campsite OS supports this transition through its IoT integration, which reads electricity and water meters via MQTT and links consumption data directly to guest bookings. The invoicing module then generates clear, itemised bills that guests can understand and trust.

Actionable next steps for operators:

1. Commission a site audit to understand current electrical and water infrastructure and identify gaps.
2. Clarify any local requirements for metering and utility resale with a qualified advisor.
3. Request quotes from metering system suppliers, specifying calibration certification requirements.
4. Pilot the system on a subset of pitches before full-site rollout to test software integration and guest communication.
5. Request a demo of Campsite OS to see how the IoT integration and invoicing workflow can support your metering project.
6. Review tariff structures annually and adjust to reflect changes in wholesale utility costs.

The technology is mature, and the financial case is compelling. Operators who implement per-pitch metering gain control over their utility costs and offer guests a billing model that is straightforward and fair.
