Quote faster. Win more of the right jobs.
Dwellinger turns drawings into a scope-led estimate, puts approved planning applications in your pipeline, and keeps every call, WhatsApp and follow-up on one job record. It is the platform RCB Group built because nothing else did all of it.
Pre-launch. Founding contractors get access first, in small groups, with pricing before anyone else.

If you have ever been the last builder they called
You had three days to turn drawings into a quote while running two sites. The homeowner had two other quotes already. You sent a one-page figure. They went with the one that came back first and said the most. That is the job Dwellinger was built to fix.
Scope-led estimates from drawings
Start from a loft, extension, refurbishment, kitchen or bathroom template, not a blank spreadsheet. Quantities first, prices second, so the client sees what they are paying for, room by room.
Estimating & scope →Planning leads, in your pipeline
Approved and pending applications from councils around the M25 land as leads you can qualify, not a spreadsheet you forget to open.
Planning leads →One pipeline for every conversation
Calls, SMS, WhatsApp, email and web enquiries logged on the lead. Stale leads flagged at 3 and 7 days. Follow-ups that happen because the system asks, not because someone remembered.

Short call, your jobs
We walk through how you quote and run jobs today, and show you the platform on a real project, not a demo deck.
Founding terms, then access
Pricing goes to the list first. Founding contractors come on in small groups so each one is set up properly.
Proof: the projects it runs today
Dwellinger is the platform behind RCB Group, a London property project delivery business (RCBS Limited, Company No. 09500269, incorporated 2015). These are RCB Group projects, not stock images and not visualisations.



Questions contractors ask us
Is Dwellinger live now?
Not for the public yet. The platform runs RCB Group's own loft, extension and refurbishment work every day. Founding contractors get access before anyone else, in small groups, so we can onboard each one properly.
What will it cost?
No public price list yet. Founding contractors hear pricing first and lock in founding terms before launch. Joining the list costs nothing and commits you to nothing.
Is this just another lead site?
No. Leads are one part. The point is the whole job in one place: the drawings, the scope, the estimate, the calls and WhatsApps, the follow-ups and the stage payments, so nothing lives only in someone's head.
You are a contractor. Why would I use a competitor's software?
RCB Group built Dwellinger because nothing on the market did the job. It is being opened to other contractors as a separate product. Your data is yours, stays in your account, and RCB Group does not see your leads or prices.
Will my team actually use it?
That was the test on RCB Group's own team: office staff, estimator and site. Leads land from calls, WhatsApp and web forms without anyone re-typing them, and the estimator works from templates rather than a blank page.
