Why Appoint an M&E Builder Directly? Save 15%+, No JCT, No Retention
The architect-nominated model explained — no main contractor in the chain, no markup, no retention
2026
On most building projects the mechanical and electrical works are buried inside the main contractor's lump sum — along with a 15%+ markup you never see. There's a better way: your architect nominates us, and you appoint us directly. Here's how the model works and why it saves you real money.
The Architect-Nominated Model
Your architect designs the M&E scope and nominates a specialist builder to deliver it. Crucially, you — the client — appoint that builder directly. There's no main contractor in the chain and no middleman taking a cut of the M&E works. You get a specialist's quality at a specialist's price, with your architect still supervising the design intent.
The Main Contractor's 15%+ Markup
Main contractors routinely add 15-25% on top of the M&E package to cover coordination, overheads and profit. When you appoint the nominated M&E builder directly, that markup disappears. On a £60,000 M&E scope that's £9,000-£15,000 back in your pocket — spent on better materials, or simply saved.
No Main Contractor Means No JCT
JCT contracts govern the relationship between the client and the main contractor — payment, variations, delay and dispute provisions. With no main contractor, there's no JCT contract to negotiate, administer or argue over. Your direct agreement with us is simple and transparent, while your architect's professional indemnity insurance still covers the design.
Retention Explained — and Why None Is Held
Retention is a percentage of the contract sum the main contractor withholds until defects are fixed — typically 5%, often held for twelve months. It exists to protect the client from poor workmanship. Because we're accountable directly to you and your architect, and because we want your recommendation and review, we don't hold retention. You keep your money; we earn our reputation.
10/60/30 — Funded by Your Own Credit
- 10% on design
- 60% before materials are ordered
- 30% on completion
The works are funded by your own consumer credit: 0% point-of-sale finance, green loans from ~3.5% APR, or the Warm Homes Loan on heat pumps. You pay us directly, with the same consumer protections you'd get on any purchase — and none of the money is tied up in retention.
Compliance & Certification
As your nominated M&E builder, we carry the accreditations your project needs:
Design, compatibility and compliance in one package — coordinated with your architect, accountable to you.
