Meter Types, Supplier Support, and Quote Process ⏱️

This article explains:
• What Half-Hourly (HH / Profile 00) actually means
• The different HH meter types (including CT meters)
• Which suppliers typically support each type
• The correct quote process

Read this before raising HH tickets. It will save you time.

1️⃣ What “Half-Hourly (HH / Profile 00)” Means

Half-Hourly (Profile Class 00) means the site settles electricity usage in 48 half-hourly periods per day.

HH is a settlement category, not a single meter model.

All HH meters:
• Record consumption every 30 minutes
• Require full HH data for pricing
• Are priced and risk-assessed differently by suppliers

However, not all HH meters are equal.

2️⃣ HH Meter Types (This Is Where Most Confusion Happens)

🔹 Whole Current (WC) HH Meters

What they are
• The meter measures current directly
• No external transformers
• Typically lower-capacity sites

Commercial reality
• Broadest supplier support
• Still subject to minimum EACs and credit rules
• Easier to price than CT meters

Typical use cases
• Smaller HH sites
• Lower kVA connections

🔹 Current Transformer (CT) HH Meters

What they are
• Use external Current Transformers (CTs) to step down high current
• Required for high-capacity supplies
• Always indicate a more complex, higher-risk site

This is critical:
CT meters are a subset of HH meters, but they are not supported by many suppliers.

Commercial reality
• Supplier support is limited
• Higher minimum EAC thresholds
• Stricter credit and underwriting
• Multi-year terms often unavailable

This is why many HH tickets end with very few options.

🔹 AMR (P2) vs Smart HH (P4)

This is a communications distinction, not a supplier acceptance one.

• AMR / P2: Older HH meters with bolt-on comms
• Smart HH / P4: Integrated smart HH meters

👉 This does not materially change supplier eligibility.
The deciding factor is almost always WC vs CT + consumption size.

3️⃣ Supplier Support Reality (Acquisitions)

⚠️ CT HH Meters — Typical Position

EDF I&C
• Minimum EAC: ~500,000 kWh
• Below this: not supported

British Gas Business (BGB)
• Minimum EAC: ~350,000 kWh
• Must also pass banding (Bands 1–4 only)

E.ON
• Not supported for CT HH acquisitions

Smartest Energy
• Not supported for CT HH acquisitions

Valda Energy
• Supported for 1-year terms only
• Subject to credit approval
• Matrix pricing only

📌 For sub-threshold CT HH sites, Valda 1-year is usually the only viable outcome.

⚠️ Whole Current HH Meters

• Wider supplier access than CT
• Still subject to EAC thresholds
• Still require full HH data and documentation

Do not assume WC = easy; it is simply less restrictive than CT.

4️⃣ HH / 00 Quote Process (Mandatory)

All HH quotes — WC or CT — follow the same process.

👉 HH quotes must be logged via a ticket.
Emails are not monitored for HH pricing.

📄 Required Documents (All Mandatory)

Attach all of the following:

1️⃣ 12 months HH consumption data (Excel format)
2️⃣ Recent bill (issued within last 3 months)
3️⃣ Valid LOA matching customer name and supply address

Missing any item will block or delay the quote.
These are supplier rules, not BOS policy.

🧮 Valda Price Lookups (Important)

When using Valda matrix pricing:

• Load the correct regional tab
• Match the LLF column only

That’s it.

❌ Do not match Profile Class
❌ Do not match MTC / SSC

These values do not affect the price for Valda HH matrix rates.
Matching the region + LLF gives the correct price.

5️⃣ BGB Banding Check (If Relevant)

Before submitting for BGB:

📁 Pricing → BGB → TCR BANDING TOOL v3.xlsx
Enter:
• PES
• LLF

Valid bands: 1–4
If it returns 0, BGB will not support that configuration.

Check banding before raising follow-up tickets.

6️⃣ Common Questions (Answered Once)

“Can BOS make an exception?”
No. Supplier underwriting rules are fixed.

“Can we try anyway?”
Submitting below thresholds results in rejection and delays.

“Why did I have to raise a ticket if the answer is no?”
HH tickets validate eligibility; they do not override supplier rules.

“Why am I being told Valda 1-year only?”
Because CT HH + sub-threshold consumption removes other options.

7️⃣ Best Practice (Read This)

• Confirm HH type first (WC vs CT)
• Check EAC against supplier minimums
• Assume Valda 1-year for small CT HH sites
• Raise one complete ticket, not multiple partial ones

🔁 Re-raising or bumping HH tickets will not change supplier acceptance.

📣 Final Word

Half-Hourly quoting is about eligibility first, pricing second.

Most HH frustration comes from misunderstanding meter type, not missing paperwork.

Submit once.
