Energy Auditing, Billing, and Compliance

Every pound your organisation spends on energy should go exactly where it’s meant to. Yet across mosques, charities, and small businesses, overbilling and misapplied taxes are common. This guide gives you a simple but rigorous approach to auditing, correcting, and staying compliant, so you can protect your funds and your reputation.

Why every community site needs an energy audit

Auditing isn’t about chasing mistakes, it’s about gaining control. When you verify your bills and metering, you remove uncertainty and stop silent cost creep. Many businesses unknowingly overpay due to estimated reads, outdated tariffs, or incorrect VAT treatment.

An annual audit establishes truth: what you used, what you paid, and whether it’s correct. From there, you can plan savings with confidence instead of guesswork.

Step 1: Verify your billing accuracy

Start with one recent electricity and gas invoice. Check for these red flags:

“E” next to readings, which means they’re estimated, not actual.
VAT applied at 20% if you qualify for 5% (charities often do).
Incorrect Climate Change Levy (CCL) charges.
Billing for meters that no longer exist.
Standing charges that jumped with no notice.

If you see any of these, you’re probably overpaying. Our step-by-step guide explains how to correct it: Bill Audit Checklist – How to Spot Overcharges Before They Grow.

Step 2: Reclaim overpaid VAT and CCL

Charities and religious sites often qualify for a reduced 5% VAT rate – but suppliers apply 20% by default. Over time, this adds up to thousands in recoverable charges. You can back-claim up to four years by submitting corrected VAT declarations with proof of charitable status.

Step 3: Track and store consumption data

Smart meters are useful only if you use the data. Download usage reports quarterly and store them in a shared folder. When you can see consumption trends, you can justify efficiency projects and negotiate better rates at renewal.

Step 4: Ensure compliance and accountability

Energy management isn’t just about cost, it’s about legal and ethical duty. Managers have a responsibility to ensure accurate billing and transparent reporting. Keep the following compliance records:

Annual meter verification log (with photographic readings).
Copies of all supplier contracts and terminations.
VAT declarations and exemption certificates.
Energy consumption summary for each financial year.

Storing these in a shared digital folder builds continuity.

Step 5: Use audits to prepare for renewals

Once you’ve verified your data, procurement becomes easier. Knowing your exact usage lets you get like-for-like quotes. It also protects against inflated estimates used to push higher tariffs.

Once your data is accurate, it’s time to think long-term. Use your audit results to plan sustainability measures that reduce future spend. Learn more in Budgeting, Efficiency & Sustainability.
