How WCCP fits into your application
Quote, slot, deliver.
We're not the people who fill in the application — that's between you and the RPA. What we do is the bit that makes the rest of the application solid: documented capacity, SSAFO 2018 compliance, a manufacturing slot you can rely on.
- 01
Get your storage capacity right
SIG Round 4 requires demonstration of at least 6 months of slurry storage. We supply capacity calculations and SSAFO 2018-compliant spec sheets with every quotation.
- 02
Itemised quote on the standard grant template
We provide quotations on the recognised scheme eligible-items format. Your RPA application picks up the figures verbatim — no re-keying, no version mismatch.
- 03
Manufacturing slot held
Quoted lead time is typically 4 weeks once a grant offer is confirmed. We hold a manufacturing slot at the yard against your offer letter.
- 04
Delivered, installed if you want it
We deliver UK-wide on our own HIAB fleet. We can also project-manage the install — slab, panels, fittings — for a turn-key job.
