In short
Once a site has its MPAN or MPRN, everything that follows sits on the supply side and has a fixed order. The supplier appoints the metering agents, so no contract means no meter.
A4 board pack. Cover page, then a running head and foot on every page.
The sequence
- Contract. The supply goes to market and a contract is agreed. Nothing downstream can start until this is done.
- Metering appointment. The supplier appoints the meter operator and data agents.
- Meter fit. The meter is installed and the supply energised.
What has to be ready on the day
The meter cannot be fitted into an unfinished position.
- Safe, permanent access to the meter position, with the site able to receive the engineer.
- The meter position itself complete: board, enclosure and any builder’s work finished.
- The correct isolation in place, and the incoming service terminated and live.
- Someone on site with authority to sign the work off.
A failed appointment costs the slot, not just the day. The next one is scheduled from the point of rebooking.
What we need from you
Site address and supply point number, the expected consumption and load, the legal entity taking the supply, and a contact who is actually on site.
The expected load matters more than people assume. A meter specified against the wrong load has to be changed later, at the site’s cost and on the metering agent’s timescale.
Where the delays come from
Almost always one of three things: the contract was not in place, so the metering appointment never started; the meter position was not ready on the day; or the entity taking the supply changed part way through and the contract had to be redone.
All three are avoidable and none of them are the meter operator’s fault.
Questions
What has to happen before a new meter can be fitted?
A supply contract has to be in place, because the supplier appoints the metering agents. Without a contract there is no metering appointment.
What makes a meter appointment fail?
Most often an unfinished meter position, no safe access, or no one on site with authority to sign off.
What information is needed to set up a new supply?
The address and supply point number, expected consumption and load, the legal entity taking the supply, and an on-site contact.
