Sub-Metering

A whole-building bill may not explain a high baseload or differences between areas. Sub-metering can support investigation where the measured boundary is clear. Decide what question the new meter should answer before choosing its position.

Discuss your requirements

Defined services, clearly scoped.

Overview

Describe the outcome required as well as the immediate issue. The starting information should identify the location, people affected and any change in use, so the assessment addresses the current requirement rather than simply repeating the previous arrangement.

What the service can include

The brief identifies loads or areas, meter type, installation, communications and reporting. It records units, coverage and how readings relate to the main supply. Billing use, where intended, needs the appropriate separate assessment and arrangements.

Decisions that shape the service

A sub-meter does not automatically provide a complete energy balance. Unmetered loads, timing differences and data gaps can leave a difference from the main meter. The report should explain these rather than force totals to agree through unsupported adjustments.

The proposal identifies the responsibilities that remain with the site or property team and the work included in our instruction. Connected repairs and specialist activities receive their own clear scope, so each person understands what they must arrange and what records they will receive.

Assessment and preparation

Provide electrical or utility drawings, main-meter data and the systems to investigate. Identify access and shutdown windows. Agree the reporting interval and the person who will use the results.

How the service proceeds

We establish the measurement boundary and installation requirements, then define the meter and data arrangement. Handover records references, coverage and access. Initial readings are considered with the system context and any known gaps.

For several sites, we agree consistent reporting and escalation while retaining local contacts and operating requirements. Each action stays connected to its building or service area, with a named route for decisions that affect the wider operation.

Cost, timing and disruption

Meter numbers, routes, access, communications and reporting affect cost. Installation shutdowns and ongoing data services may add requirements. Compare the information needed with the practical effort to maintain the meters.

Tell us about operating hours, critical periods and the activities that must continue. The programme and price should reflect those constraints, including any phased delivery, additional access arrangements and reporting needed by the operational team.

Sector applications

Offices need work coordinated with staff and visitors. Retail needs trading and deliveries considered. Hospitality brings guest areas and food operations into the brief, while education needs access planned around teaching. Our complete service and project offering supports all sectors, with the arrangements based on each site's actual activity.

Local coverage

We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. View all locations.

For a multi-site requirement, provide the local contact and working restrictions for each address. A common service brief still needs the differences between premises recorded.

Frequently asked questions

Can sub-meter totals differ from the main meter?

Yes. Coverage, timing and unmetered loads can explain differences that need investigation.

Does a sub-meter automatically support tenant billing?

No. Establish the relevant billing requirements and meter suitability separately.

Can one meter identify every equipment load?

Only the load within its defined boundary is directly measured. Further detail may require another approach.

Can sub-metering support an energy audit?

Yes. It can improve visibility where the selected measurements answer a clear operating question.
