ESOS Phase 3 Compliance

From “in a pickle” to fully compliant in seven weeks.

KAB Seating — a 228,517 sq ft manufacturing facility in Northampton — came to KEES with two weeks until our site visit and an ESOS deadline closing fast. Here's how we used half-hour electrical data, a maintenance-week visit and a tight focus on practical findings to get them compliant — and identified 25% of total energy spend in available savings along the way.

01 · The Challenge

What KAB needed — and the clock they were on

Tight deadline, complex site, and an ESOS submission that needed to actually mean something.

KAB Seating manufactures specialist seating from a 228,517 sq ft facility in Northampton with continuous demand from a compressed-air system and an attached paint facility — two of the most energy-hungry processes in industrial manufacturing.

They came to KEES already late in the cycle. Time was not on their side and they were not in a position to spend weeks shopping around. From initial introduction to site visit was two weeks. From kick-off to full compliance: seven.

The brief wasn't only to file a compliant report — it was to find the savings that mattered, even though the company is set to relocate to a new facility in 2026. We had to be ruthless about which findings made the cut, and which were noise.

02 · The Data

Operational vs non-op weeks

Pre-analysis showed a clear bimodal pattern — letting us pinpoint plant that ran when nobody needed it.

Compressed-air peaks

Recurring 380 kW peaks tied to a single compressor regime. Small control change, big saving.

Out-of-hours base load

~90 kW continuous overnight load — heating controls and standby loads on 24/7 unnecessarily.

03 · Key Findings

Six themes — three of them ready to act on day one.

F.01

Continuous demand from compressed-air system

Largest single energy load on site. Control regime, leaks and pressure setpoints all in play.

F.02

Paint facility process load

Continuous extract and conditioning even outside production hours. Sequencing opportunity identified.

F.03

Heating system controls

Set-points and time-clocks not aligned to the operational shift pattern — running outside need.

F.04

Lighting system & control

Mixed age estate, sub-optimal zoning in non-production areas, no daylight or occupancy linkage.

F.05

Staff engagement opportunity

Behavioural and shift-handover changes that cost nothing, but reduce the persistent base load.

F.06

Data management & reporting

Integration of ESOS into the wider SECR reporting cycle to remove duplication and improve trust.

04 · The KEES Approach

Dive into the data first. Then walk the floor.

Compliance is the floor, not the ceiling. We sequence the work so the audit produces an Action Plan you can actually use — not a binder that goes in a drawer.

STEP 01

Pre-analyse half-hour data

Before any site visit, we load 12 months of half-hour electrical data and identify biggest users, base load and the operational pattern. The site visit is targeted as a result.

STEP 02

Live-load logging on site

First task on site: install temporary loggers on the biggest users so we can read the audit live, not in retrospect. Confirms or challenges the desk findings.

STEP 03

Walk every process — including the dull ones

A thorough audit of all the processes, not just the obvious ones. The compressor and the paint line were obvious — the heating control and lighting weren't.

STEP 04

Build the Action Plan around the relocation

KAB are moving facility in 2026 — so we prioritised only the most practical findings with the quickest returns. No one funds a five-year payback on a building you're leaving.

STEP 05

Stay through to compliance

We supported KAB through every step of the ESOS process — submission, Lead Assessor sign-off, regulator correspondence — until compliance was confirmed.

06 · Client testimonial
To be completely honest we were in a pickle with our ESOS submission. We needed an expert who could hit the ground running. Tenacious, detailed and an “energy geek” of the highest order — Kiro went straight to the heart of the matter. Truly a trusted partner for us going forward.
