Why the MPAN matters for electricity quotes
The MPAN is a 13-digit reference unique to your electricity meter. It confirms your distribution network area, which affects network charges, and your meter type, which affects whether you are quoted a single rate or a time-banded rate. Without it, a quote is only a rough regional estimate.
What suppliers need alongside the MPAN
- Annual electricity consumption in kWh
- Current supplier and contract end date
- Business address and postcode
- Meter type (standard, smart or half-hourly)
- Payment method preference, which can affect the rate
Quotes for standard versus half-hourly meters
Businesses on standard meters usually receive a single unit rate quote that can often be generated instantly online. Half-hourly metered sites, common among larger consumers, receive quotes that separate the unit rate from a capacity charge based on the site's maximum demand, and these often require manual review by the supplier's pricing desk.

Comparing electricity quote structures
| Meter type | Typical quote structure | Turnaround |
|---|---|---|
| Standard/smart | Single unit rate plus standing charge | Often instant |
| Economy 7 style | Day and night rates | Often instant |
| Half-hourly | Unit rate plus capacity charge | A few working days |
How long an electricity quote stays valid
Because wholesale electricity prices fluctuate daily, quotes typically carry a validity window, often somewhere between 48 hours and a few weeks depending on the supplier. Larger or half-hourly quotes can have shorter validity given the added pricing complexity, so it is worth confirming the expiry date before deciding.
What to check before accepting an electricity quote
- Confirm whether the rate is single, time-banded or half-hourly
- Check the standing charge and any capacity charge separately
- Confirm the contract length and renewal terms
- Check for exit fees if leaving a current contract early
- Confirm the proposed start date lines up with your current contract end
