Key takeaways
- Turnkey means one contract and one accountable party from design to handover.
- Separate trades can look cheaper but move coordination risk — and its cost — to you.
- Most delays happen at the interfaces between trades, not within them.
- For small single-trade jobs, hiring directly can be fine; for multi-trade renovations, turnkey usually wins.
Every renovation involves the same question: do you hire one company to deliver everything, or do you appoint a designer, a fit-out contractor, an electrician, a joiner and a stone supplier yourself? Both models exist for good reasons. Here is an honest comparison.
What "turnkey" actually means
In a turnkey contract, one company is responsible for the entire result: design, approvals, procurement, construction, MEP, joinery, finishes, cleaning and handover. You deal with one project manager and sign one contract. If something goes wrong, there is no debate about whose fault it is.
With separate trades, you become the coordinator. You schedule each trade, resolve clashes between them, approve their work and absorb the consequences when one delays another.
The comparison
| Turnkey contractor | Separate trades | |
|---|---|---|
| Contracts | One | Many |
| Accountability | Single point | Split — often disputed |
| Your time required | Decisions and approvals only | Daily coordination |
| Headline price | Includes coordination | Looks lower |
| Risk of delays | Managed by contractor | Carried by you |
| Design consistency | Designer and builders work together | Depends on your coordination |
Where the hidden costs are
Most renovation problems don't happen inside a trade; they happen between trades:
- The joiner measures before the plasterer finishes, and the wardrobe doesn't fit.
- The electrician runs cables before the kitchen layout is final.
- The tiler starts before the waterproofing is tested.
- Three companies blame each other for a leak — and none fixes it.
Each interface costs days, rework and frustration. A turnkey contractor plans these interfaces in the programme, because its own team carries the consequences.
When separate trades make sense
Hiring directly can be the right choice when:
- The job involves one trade only (painting, a single bathroom fixture, a wardrobe).
- You have construction experience and time to supervise daily.
- You already have an architect acting as project manager.
When turnkey is the better choice
- Multi-room or whole-property renovations
- Projects that include MEP, layout changes or approvals
- Owners living abroad or with limited time
- Investors who need a fixed timeline to sell or rent
- Anyone who values a single guarantee for the finished result
What to ask a turnkey contractor
- Do you have in-house design and engineering, or do you subcontract them?
- Who will be my single point of contact, and how often will I get updates?
- Is your quotation itemised, and what exactly is excluded?
- How do you handle approvals?
- What does your snagging and handover process look like?
- Can I see completed projects — ideally before-and-after?
At Heritage Turnkey, design, engineering, joinery and project management sit in one team under German leadership. That structure is the reason we exist: to make renovation feel organised, predictable and calm.
FAQ
What is a turnkey renovation contractor?
A contractor who takes full responsibility for design, approvals, construction, MEP, joinery, finishes and handover under one contract, so the client receives a finished, ready-to-use space.
Is turnkey renovation more expensive?
The headline price can be higher than adding up individual trade quotes, but it typically includes coordination, approvals, protection and snagging that separate quotes exclude — and it reduces the risk of costly delays and rework.
When should I hire trades separately?
For a single, simple job — painting, replacing a vanity, fitting wardrobes — hiring one specialist directly is reasonable. Once three or more trades depend on each other, coordination becomes the main risk.
