All E.ON and Scottish Power submissions must include a fully completed BOS Prep Form.
Incomplete or inaccurate forms are the main cause of rejected sales, delays, and repeat tickets.
Every field on the form must be correct before submission. BOS does not amend clerical errors; it is the broker’s responsibility to ensure accuracy.
Check the following every time before submitting:
Company name matches Companies House * (no abbreviations or trading names).
Company number corresponds to the same entity on Companies House *.
Director names match Companies House records * (where applicable).
MPAN / MPRN entered correctly; double-check the final digits.
Start date confirmed with the customer.
Letter of Authority (LOA) signed and matches the same legal entity.

Company name and number from two different businesses.
Wrong start dates or missing supply details.
Using old or locked PDF versions of the form that cannot be edited.
Spelling errors or incomplete customer details.
If renewal - sending prep form company name and/or director details different to existing renewal.
The ticket is placed on hold until a corrected form is received.
Each incorrect submission restarts the review queue and delays contract processing.
BOS does not correct clerical errors; the form must be fixed and re-sent.
Repeated mistakes may result in restricted supplier access.
Ideal workflow:
1️⃣ Message 1: Prep form sent. ✉️
2️⃣ Message 2: Prepared contract returned. ✅
Simple. Two messages. Done. We like the above very much!
Common (and unnecessary) nightmare:
1️⃣ Message 1: Prep request… with no form attached. 🧐
2️⃣ Message 2: “Please send us the form” — we are good, but not clairvoyant. 🔮
3️⃣ Message 3: Form finally arrives... small victory. 🏆
4️⃣ Message 4: Company name and number mismatch — which one is correct? (Crystal ball still broken.) 🧙♂️
5️⃣ Message 5: Direct paste from Companies House, no correction on the form — apparently BOS does the admin! 🧾
6️⃣ Message 6: Cross-checked finally, logged, but since its at closing time, because yes, we sleep too, it is sent next day. 😴
Avoid this chain by submitting a fully checked, correct form the first time. We like easy days too.
