Why Can't We See Which of Our Restaurants Is Using Too Much Gas and Electricity?

Restaurant group energy bills arrive late, estimated and hard to compare between sites. We build a site energy view from meter data, bills and trading hours.

Quick answer — TL;DR

Energy is one of the largest overheads in a restaurant group, but bills arrive late, some are estimated, and they cover different periods at each site, so nobody can say which kitchen is wasteful. We build a site energy view that reads half-hourly or smart meter data where available, and bills where not, and compares usage by site against trading hours and covers, with out-of-hours usage flagged.

Bills that tell you nothing until it is too late

The electricity bill for one site arrives with a large catch-up charge after months of estimates. Another site's gas usage looks higher than a similar-sized restaurant down the road, but the bills are for different periods and one includes a standing charge adjustment. The finance team pays them, codes them to sites and moves on. The ops director asks which sites use the most energy per cover. Nobody can answer without a week of spreadsheet work.

Meanwhile, at one site, the extraction fans have been left running overnight for months, because the timer broke and nobody noticed. At another, the opening chef switches on every oven, the chargrill and both fryers at 7am out of habit, though prep does not need them until ten. Neither of these shows up on a quarterly bill as anything other than a slightly higher number, easy to blame on prices.

Why energy stays invisible

  • Bills come from different suppliers and cover different periods at each site.
  • Many bills are estimated until a meter read is taken.
  • Half-hourly or smart meter data exists at some sites but nobody looks at it.
  • Usage is never compared with trading hours or covers, so a busy site looks wasteful and a wasteful one looks busy.
  • Kitchens have many large loads, such as ovens, fryers, extraction and refrigeration, that are left on out of habit.

What you pay for not seeing it

Waste you cannot see is waste you cannot fix. Equipment left on outside trading hours, faulty refrigeration working harder than it should, and ovens switched on at 7am for a noon service all add up across a group. Billing errors and estimates go unchallenged. And when contracts come up for renewal, the group negotiates without a clear picture of what each site uses and when.

How we build the site energy view

  1. We collect meter data from your supplier or meter operator where half-hourly or smart data is available, and bill data for sites where it is not.
  2. Each site's trading hours, covers and sales are read from the EPOS and booking systems.
  3. Usage is shown by site, day and half-hour, with trading hours marked, so out-of-hours consumption stands out.
  4. Sites are compared on usage per cover and per trading hour, so different sizes and formats can be compared fairly.
  5. Unusual patterns, such as night-time usage rising or a sudden step change, are flagged to the facilities or ops manager.
  6. Bills are checked against meter data, and estimated or disputed bills are listed for finance.
What we look atWhat it often reveals
Overnight usageExtraction, lighting or equipment left on
Morning start timeEquipment switched on long before prep needs it
Usage per coverSites or kitchens less efficient than their peers
Step changesA fault, such as a failing fridge compressor

What you do about it, whether new equipment, timers, contract changes or staff habits, stays your decision. The view shows where to look.

Energy on the Monday report

The ops team sees each site's energy use beside its trading, and the site with overnight usage gets a visit. Kitchens can see their own start-up pattern and whether switch-on times drift earlier. Finance has bills checked against meters. At contract renewal, the group knows its usage profile by site.

Does this sound like your estate?

  • Energy bills arrive late or estimated.
  • Nobody compares energy use between sites.
  • Smart meter data exists but nobody looks at it.
  • Equipment is sometimes left on overnight.
  • Bills are paid without being checked against meter reads.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Do we need smart meters at every site?

No. Sites with half-hourly or smart data give the most detail. Others can be compared from bills, less precisely.

Do you install sub-meters?

We do not install hardware ourselves. If you add sub-meters through an installer, we can read their data.

Will this reduce our bills?

It shows where energy is used and where it looks wasteful. Any saving depends on what your teams change.

What drives the cost?

How meter data can be reached for each site, the number of sites and how far you want bill checking to go.

What do you need from us?

Your supplier accounts and meter details, recent bills and access to EPOS trading data.
