“Extension went smoothly from start to finish. Communication was great throughout, and the team delivered exactly what we asked for. Thank you, 2VP!”

Total transparency

What’s in the number — and what isn’t.

The estimate is your all-in construction price: two figures reach you — construction (ex-VAT) and VAT. Every rate is all-in, so nothing is bolted on at the end.

These are already in the price you see — the perks below don’t add a penny to your estimate. They’re what “all-in” means at 2VP.

HOW WE WORK

How we run a London build: one team, one contract, a finish date

Six things that change how a project runs. Honest about what costs extra, honest about what we’re not. If something here looks wrong for you, we’re probably not the right builder — that’s fine, we’ll say so on the call.

DASHBOARD
01

Live client dashboard

Every project gets a private dashboard. You see variations, open issues, payment schedule, daily photos from the foreman, and a weekly written report from the project manager. Decisions take minutes, not phone-tag.

SAME · TEAM · EVERY · JOB
02

Same teams, every job

We don't subcontract to whoever is cheapest that month. The carpenters, electricians and plasterers you meet on day one are the same ones who finish on day 84. We know how they work. They know how we work.

03

We work on reputation

About 70% of our work comes from referrals. We're careful about who we take on — we'd rather turn down a job than fit one in that we can't deliver properly. That works both ways: we expect the same care from our clients.

Real structure, not one-man-band

Director, PM, foreman, QS, H&S, accounts — proper company structure. We cost more per day than a sole trader. You save more overall because nothing gets done twice. Less wishful pricing. Fewer surprises.

Fully insured · IBG available

£5M public liability + contract works cover, on every project — included. Optional Insurance-Backed Guarantee via HomePro adds 10 years' workmanship cover on top, at +2.5% of contract value if you want it. Most clients with mortgage take it.

Where you can save

Self-supply your kitchen or windows — we'll fit, you pocket the margin. Phase the project over two financial years. Pick Balanced spec for the kitchen, Signature for the floors. We'll show you the levers and the trade-offs — you decide.

One promise: the estimate you receive is calibrated against projects we’ve actually built — not aspirational pricing to win a beauty parade. If our numbers come in higher than another builder, we’ll explain exactly why. Usually it’s the things you can’t see in their quote.
