One-Stop Trade Supply
Four Supplier Runs, or One Stop
Every extra supplier is another drive, another queue and another invoice to file. It all happens before the first frame goes in.
Before working with Cii
The knock-on effects
Hours on the road
Driving between the frame supplier, glass merchant and trim counter pushes back the start of every job.
Paperwork from every supplier
An invoice or receipt from each one, all to match to the right job and the VAT return.
One late supplier holds up the job
If the glass is not ready, the frames sit on site and the customer waits.
Minimum orders
Buy a box when the job needs three tubes, then carry the rest round in the van.
A separate tip run
Old frames and glass cost at least £100 to dump, before fuel and time.
After working with Cii
One stop at Cii
One counter
Frames, glass, roof glazing, trims and consumables from Danes Road, Romford.
No minimum order
One tube of silicone or a full house of frames.
One supplier sees the whole order
Realistic lead times up front, with frames and glass planned together.
Waste off the van
Drop the last job's old frames and glass while you collect. Included.
One invoice per job
Everything for the job on one invoice, so the paperwork matches the job it belongs to.
One person to call
Ross and the trade desk, not a call centre. Practical payment terms for approved trade accounts.
What We Supply
Everything you need for the job, not just the frames
Stop splitting orders across multiple suppliers. Windows, doors, roof glazing, glass, trims, silicones, and everyday install stock, all through one trade relationship. Order frames and site consumables together, collect in one go, and drop off job waste while you are here.

Trade doors
Bi-folds and Sliders
AluK, Cortizo and Liniar bi-folds, EdgeGLIDE+ and Eurogroove sliders, with the thresholds the systems publish.
Trade bi-folds and sliders
Roof Glazing
Roof lanterns and flat roof products supplied alongside the rest of your package when the job needs more than frames alone.
Trade roof glazing
Hardware and Site Essentials
Friction stays, espags, gearboxes and cylinders matched to the old part, plus the trims, vents and fitting materials for the job.
Trade hardware
Sealed Units and Glass
Double and triple glazed units, single panes and safety glass, made to the sizes you send.

Windows, doors, bi-folds and roof lanterns, viewed inside and out, on a brick or rendered wall.
Quote from the design
The configuration becomes the quote. No retyping sizes into a spreadsheet.
Drawings and specification
Dimensioned drawings, outside and inside views and the spec for each job, as one PDF.
Customers and jobs in one place
Every quote stays with the customer and site, alongside the Cii order forms.
Essentials on the same job
Hardware, consumables and sealed units added to the job, not a separate phone call.
