We design modular buildings that last 25–40 years, give existing buildings a second life, and are committed to Net Zero by 2050.
JCPSA is formally committed to achieving Net Zero greenhouse gas emissions by 2050, in line with the UK Climate Change Act 2008 and the Paris Agreement.
This is not a distant aspiration — it is a binding pledge signed by our CEO, Paul Nuckowski, and embedded into how we design, manufacture, and deliver every building.
We measure our Scope 1, 2, and 3 emissions annually, set reduction targets, and publish our progress transparently. Because accountability matters more than ambition.
“We started this company because we believed modular buildings could be better — better quality, better design, and better for the environment. Net Zero isn’t a marketing exercise. It’s the standard our clients and their communities deserve.”
— Paul Nuckowski, Founder & CEO
30% of our business is refurbishment
Most modular buildings are designed to last 10–15 years. When they reach end of life, they are demolished and sent to landfill. We take a different approach.
Approximately 30% of JCPSA’s work involves purchasing used modular buildings, stripping them back to their steel frames, replacing every panel, window, and system, and delivering a building that will serve for another 25–30 years.
This process uses approximately 46% less embodied carbon than manufacturing a new building from raw materials. The steel frame — the most carbon-intensive component — gets a second life instead of being scrapped.
It is manufacturing without the waste. And it delivers a building indistinguishable from new.
The most sustainable building is the one you do not have to replace. Every JCPSA building is engineered for a 25–40 year operational lifespan — up to four times longer than the industry standard.
Structural Frame Warranty
No-Fade Coating Warranty
Aluminium Systems Lifespan
Roofing Membrane Warranty
Every new JCPSA building is specified with energy-efficient systems as standard. Our clients do not pay extra for sustainability — they receive it as part of the specification.
Compared to conventional gas heating. Specified as standard on all new buildings, reducing operational carbon from day one.
Through MVHR systems. Fresh air in, heat retained — reducing heating demand without compromising air quality. Our own office MVHR system halved AC demand and improved CO2 levels by up to 80%.
Premium insulation exceeding Building Regulations, 40-year no-fade coatings eliminating repainting and VOC emissions, and thermally broken aluminium systems for minimal heat loss.
In accordance with PPN 06/21, we publish our Carbon Reduction Plan annually. Net Zero by 2050 across all scopes. 25% reduction by 2030. 50% by 2035. Signed by our CEO and updated every year.
Unlike most modular building suppliers, JCPSA manufactures its own steel frames in-house at our Chester facility. We do not assemble — we engineer and manufacture.
• Eliminated supplier logistics — no 8–12 week waits for frames from third-party fabricators
• Direct waste control — we optimise cutting patterns and segregate all offcuts for recycling
• CNC precision cladding — minimises material waste and rework
• Off-site manufacturing — up to 90% less site waste than traditional construction
Sustainability is not a future promise. These are the steps we have already taken and the initiatives under way at our Chester facility right now.
Four adjacent workshops (2024/25)
We invested in four new workshops positioned directly opposite each other, replacing a layout where production stages were spread across the site. Result: 40–50% reduction in module movements and the associated forklift diesel consumption.
Office heat recovery ventilation (2026)
We installed an MVHR system in our own office — the same technology we specify for clients. Result: air conditioning demand halved from two units to one, and indoor CO2 levels reduced by 50–80% (from 1,500–2,000 ppm to approximately 1,000 ppm).
Employee carpooling programme (2026)
With most of our team living within 3–5 miles of the facility, we launched a formal carpooling initiative. At least 2–3 employees now share each commuting vehicle, reducing daily traffic to site and lowering our Scope 3 commuting emissions.
Yard tarmac surfacing (August 2026)
Our yard currently requires approximately 300 tonnes of stone annually to fill potholes. Permanent tarmac will allow modules to be moved on wheels rather than by forklift — an estimated further 50% reduction in forklift usage.
Welding gantry crane (late 2026)
A new welding table with overhead gantry crane will eliminate 100% of forklift beam-lifting in the welding area, replacing diesel-powered forklift operations with electric crane movements.
Solar PV pilot (H2 2026)
A trial solar panel installation on our rear storage containers — currently without electricity supply — will provide a proof-of-concept ahead of a full rooftop array on our planned new office building.
We hold ourselves accountable through independent certification and recognised environmental standards.
