See exactly what you'll pay
before we start.

Every project comes with a fixed price, an architect-led design, and a ten-year workmanship guarantee. You pay only for completed work — no deposits, no surprises.

Why 2VP exists

Every risk,
already solved.

London renovation projects go wrong at an alarming rate. Not because homeowners are naive — because the industry is structured to hide the risks. We built 2VP to make every one of them visible, and every one of them solved before you sign.

With 2VP
Fixed price

JCT contract. Price locked on signature — zero upfront deposit. No variations unless you request them.

Programme guaranteed

Written into the contract on day one. Start week and finish week are fixed — not ‘TBC at build start’.

Full paper trail

JCT contract, daily photo diary, client dashboard. You always have something to stand on.

We built 2VP specifically so this doesn't happen to you.
