Supply-only is not inherently wrong
Many residential schemes use supply-only kitchens when site joinery or a main contractor package owns installation risk. Problems appear when interfaces are unnamed: who measures, who accepts tolerance, who coordinates MEP first and second fix, and who closes snags. For vocabulary, read kitchen logistics glossary for UK residential sites.
Interface map: questions to close before manufacture
| Interface | Typical supply-only gap | What “closed” looks like in the tender |
|---|---|---|
| Measure and survey | Assumed dimensions from early GA drawings | Named survey window, tolerance band, who issues revised CNC or order amendments |
| MEP first fix | Centrelines guessed | Combined services drawing signed by MEP and kitchen supplier |
| Protection and storage | Packs damaged in corridors | Laydown rules, insurance split, delivery ticket defect clauses |
| Snagging and warranty | Product vs install dispute | Single snag list owner per defect category, response times in days |
Construction (Design and Management) Regulations 2015
On notifiable or non-notifiable sites, CDM 2015 still expects coherent information for those who build and maintain the project. Kitchen packs affect fire-stopping, access, and handover safety. If pre-construction information omits kitchen tolerance or fixing sequences, supply-only programmes discover the gap on site.
Failure mode 1: measurement and shell tolerance drift
Packs ordered on early dimensions can arrive into walls that moved within tolerance, services that shifted, or dry-lining build-ups that changed. Without a named remeasure gate and change protocol, carcass lines scribe badly and worktop runs break rhythm across plots.
Failure mode 2: MEP coordination gaps
Hob isolation, extractor duty, boiler flues, and under-sink pipework often need agreed zones. If the kitchen supplier assumes centrelines and the MEP contractor uses different offsets, second-fix becomes a cascade of cuts, infills, and warranty arguments.
Failure mode 3: protection and programme compression
Supply-only sometimes means kitchens sit in corridors waiting for a fit team that is weeks late. Damage before install is disputed endlessly unless delivery tickets and storage rules are explicit.
Failure mode 4: split warranty and snagging ping-pong
Product warranties may exclude faults caused by poor installation. Installers may blame product tolerance. A single supply-and-fit path is not magic, but a single commercial owner often shortens arguments if the contract is clear.
Failure mode 5: SKU drift across plots
Joinery teams solving problems on plot 12 may substitute handles or worktops without updating the golden spec. Handover and aftercare then fragment. Lock SKUs and exceptions; see multi-unit kitchen specification.
When to reconsider supply-only
- Tight crane or lift windows with zero storage
- Inexperienced fitting resource on high volumes
- High plot count with aggressive handover dates
