Renewal letter for a manufacturer in Oxfordshire
The unit rates on a two-year renewal were above the market. The big rise in the standing charge was fair.

| Item | Offered | Our note |
|---|---|---|
| Day rate 07:00 to 00:00 | 27.39p | 2.60p per kWh above what we could get. We quoted 24.79p. |
| Night rate 00:00 to 07:00 | 23.66p | 2.22p per kWh above what we could get. We quoted 21.44p. |
| Standing charge £ per day | Checked. £9 to £49 looks alarming, but it’s where the market now is for this kind of meter; we couldn’t beat it. The saving was in the unit rates. | |
| Pass-through chargesSet by the network operator and the government, not the supplier, so they’re the same whoever supplies you. | ||
| Capacity charge on 40 kVA | 9.26p/kVA/day | £1,352 a year. Same on our quote. |
| Nuclear RAB | 0.45p/kWh | £671 a year. Same on our quote. |
| Term | We quoted the same term, so the two are like for like. | |
| Broker commission shown | 0.0p | Our fee is 1.5p per kWh, already in the rates we quoted. |
| Sign by | 4:30pm, same day | Sign nothing yet. If your current contract needs written notice to end, send it today; it commits you to nothing. |
| Signing terms | Binding offer | Your signature is the offer. The supplier accepts by email and doesn’t need to sign. |

Fair for an HV half-hourly site: we couldn’t beat it. It’s still the line most people skip, so we always check it.
What happened
Figures from a real check, anonymised
- Offered. A manufacturer in Oxfordshire was sent a 2-year electricity renewal on 28 October 2026, with “sign by 4:30 today” in the covering email.
- Checked line by line. The standing charge had gone from £9 to £48.88 a day, but that’s the market for an HV half-hourly site. The unit rates were 2.60p and 2.22p per kWh too high.
- Outcome. We quoted 24.79p day and 21.44p night on the same term, in 2 working days, with no deadline missed. About £3,000 a year less, about £6,000 over the two years. Our fee is 1.5p per kWh, already in the rates we quoted.
How we worked out £3,000 a year
149,000 kWh a year, 70% day and 30% night. Ex CCL and VAT.
| Their renewal | Our quote | |
|---|---|---|
| Day, 104,300 kWh | £28,568 | £25,856 |
| Night, 44,700 kWh | £10,576 | £9,584 |
| Standing charge, 365 days | £17,841 | £18,465 |
| A year | £56,985 | £53,905 |
£3,080 a year less, £6,160 over the 2 years. Our standing charge was £1.71 a day higher, and that £624 a year is already taken off. At 60/40 day and night it’s still £3,023 a year.
The capacity charge and Nuclear RAB are left out because they were the same on both.
