Be seen energy monitoring: what London schemes report
The fourth stage of the London Plan energy hierarchy requires measured energy performance after occupation. What gets reported, the metering it needs, and who carries the obligation after a sale.
If your London scheme is referable to the Mayor, or your borough applies the London Plan energy policy in full, you will be reporting actual energy performance to the Greater London Authority after the building is occupied. That is the Be Seen stage, the fourth step of the Be Lean, Be Clean, Be Green, Be Seen hierarchy in the London Plan 2021, and be seen energy monitoring is secured by planning condition or section 106 obligation rather than left to goodwill. The obligation outlives your involvement in the project.
Most teams discover this at practical completion, when the meters they needed were never specified.
Where the stage sits in the energy hierarchy
The first three steps are design-stage arithmetic. Be Lean reduces demand through fabric and form, Be Clean addresses heat networks and efficient supply, and Be Green covers renewable generation, all modelled before permission is granted and set out in the energy statement submitted with the application.
Be Seen is different in kind. It asks what the building actually does once people are in it, and it closes the gap between modelled and measured performance that has dogged energy assessment for years. Nothing about it is predictive. It is measurement, reported on a fixed cadence, in a format the Authority can aggregate across London.
What has to be reported and when
Reporting happens at three points in a building's life: as designed, at the point of planning; as built, once construction is complete; and in use, annually for a period of several years after occupation. The Authority publishes the reporting template and the metrics list in its Be Seen guidance, and the template is the practical specification, so download the current version rather than working from an earlier project's spreadsheet.
The data set covers more than a single headline figure. Expect to report:
- total measured energy consumption, split between regulated and unregulated use
- on-site renewable generation, and how much of it is exported
- heating and cooling supplied from any connected network
- floor area and occupancy basis, so the figures can be normalised
- a comparison against the as-designed estimate, with an explanation where they diverge
The explanation matters more than the gap. A plant installed late, a tenant running a server room, a heat network commissioned at the wrong flow temperature: those are findings, and saying so is better than submitting a number with no narrative.
Metering needed to produce the data
You cannot report what you did not meter. The specification has to separate landlord and tenant supplies, meter each end use so that regulated and unregulated consumption can be distinguished, and meter renewable generation and export separately from consumption. Sub-metering strategy belongs in the mechanical and electrical specification at tender stage, with CIBSE guidance on metering and operational performance as the reference point.
| Decision point | What to fix |
|---|---|
| Concept design | Reporting obligation identified, metering strategy outlined |
| Tender | Sub-metering schedule, data logging, remote read capability |
| Commissioning | Meter naming, calibration, one year of data capture tested |
| Practical completion | As-built report compiled and submitted |
| Each year in use | Twelve months of data extracted and uploaded |
A remote-read metering system with a simple data export is worth the cost. Manual meter reads across a mixed-tenure block, five years running, is how reporting obligations quietly fail.
Two details catch people out. Meter naming has to match the reporting template, because a schedule labelled by riser and floor cannot be mapped to regulated and unregulated use without someone reverse-engineering it. And commissioning records need to show the meters were reading correctly from the start, since a logger installed three months after occupation leaves a hole in the first annual return that cannot be filled retrospectively.
Who holds the obligation after a sale
A condition binds the land, and an obligation under section 106 of the Town and Country Planning Act 1990 binds the land and the parties named in it. When a developer sells the completed building, the reporting duty does not evaporate. It passes to whoever owns or manages the asset, which in practice means the management company, the registered provider or the commercial landlord.
Deal with this in the drafting. Name who reports, say what happens on disposal, and put the duty into the management company's obligations and the building manual. Residential blocks need the service charge to carry the cost of data collection, or nobody will do it. Where a scheme sits in an area with a wider set of planning requirements, such as an opportunity area allocation, the energy reporting obligation usually sits alongside several other monitoring duties in the same agreement.
How the duty is secured and what failure looks like
Boroughs secure it in one of three ways: a standalone planning condition requiring submission of the as-built and in-use data, a clause in the section 106 agreement, or a monitoring obligation with a sum attached. Read which one you have, because the consequences differ.
Breach of a condition can be enforced through a breach of condition notice. Breach of an obligation is a contractual matter the borough can pursue, and some agreements attach a payment to non-compliance. Neither outcome is catastrophic on its own. Both are avoidable, and both surface during due diligence on a sale, which is usually when somebody notices the data was never collected.
There is a reputational dimension too. Boroughs use the aggregated data to test whether their policies deliver, and an asset with no submitted data is the one officers remember when the next application comes in from the same developer. Monitoring sums also sit in the agreement alongside the reporting duty, so the borough has an administrative record of who has filed and who has not.
Setting collection up at tender stage
The least costly version of this obligation is the one designed in. Build the requirement into the employer's requirements, not into a post-completion scramble.
- Check the decision notice and the agreement for the exact reporting wording and dates.
- Write the metering strategy into the mechanical and electrical specification, including data export format.
- Name the party responsible for each annual submission, and record it in the building manual.
- Test the data route during commissioning by producing a dummy annual report.
- Diarise the annual submission against the occupation date, not the financial year.
- Fund collection through the service charge or the asset management budget.
Step four is the one teams skip. Producing a dummy report before handover finds the missing meter while someone is still on site to install it.
What this changes for the application itself
Knowing the reporting duty is coming should change the energy statement you submit. Model with the metering strategy in mind, state the assumptions you will later be measured against, and avoid optimistic unregulated energy figures that will look wrong in year two. Design-stage capacity work, including a design-led approach to site capacity, interacts with this: a scheme that pushes density hard also pushes services harder, and the in-use data will show it.

Frequently asked questions
Which schemes have to report under the Be Seen stage?
Schemes applying the London Plan energy policy in full, which in practice means applications referable to the Mayor and others where the borough applies the policy to major development. Check the decision notice and the section 106 agreement, because the duty is only enforceable where a condition or an obligation records it.
How long does in-use reporting continue?
In-use data is submitted annually for a period of several years after occupation, with the exact term set by the condition or obligation on your permission. Read the wording rather than assuming a standard figure, and diarise submissions against the occupation date so the first return is not missed.
What metering does Be Seen reporting require?
Enough sub-metering to separate landlord and tenant supplies, distinguish regulated from unregulated consumption, and record renewable generation and export separately. Remote-read meters with a simple data export make five years of annual reporting manageable. Fix the strategy in the mechanical and electrical specification at tender stage.
Who reports once the building is sold?
The duty follows the land, so it passes to the owner or manager of the completed building. Name the responsible party in the section 106 drafting, write the obligation into the management company's duties and the building manual, and fund data collection through the service charge or asset management budget.
What happens if the data is never submitted?
A condition can be enforced through a breach of condition notice, and a planning obligation can be pursued as a contractual matter, sometimes with a payment attached. The more common consequence is practical: the gap surfaces during due diligence when the asset is sold or refinanced.
