Sheet 01 / 04 — The Commitment
Renovating shouldn't feel like a gamble. Renii gives you a clear cost range and flags the risks that blow budgets — before you sign a contract or spend a penny on design.
UK · Currently optimised for kitchen extensions
Sheet 02 / 04 — Uncertainty, priced
Renovation isn't stressful because of tiles. It's stressful because of uncertainty. The contract you signed excluded something you assumed was included. You found out after the work started.
Once you sign, the uncertainty becomes yours.

Comparison
| Renii | Three quotes, no framework | Hire a QS | Generic online estimate | |
|---|---|---|---|---|
| What it tells you | A structured cost range with the planning context and assumptions behind the number | Three prices — each priced to a different scope | A bespoke estimate from an independent professional | A rough £/m² figure with little project-specific context |
| When it's useful | Before you commit — while decisions are still open | After you've invested in plans and specifications | Once drawings are ready to price | Early curiosity — not a decision input |
| Cost | From free | Free — but expensive if wrong | £1,500–£3,000+ | Free |
| Independence | Independent, grounded in UK construction cost benchmarks and live planning records | Builder has an incentive to win the job | Independent expert | No project-specific grounding |
