This guide is a practical, step-by-step checklist you can follow before you pay a deposit. It’s written for real buyers (not industry insiders), and it will help you compare converters fairly, spot red flags early, and get the paperwork right.
Quick result: if you follow the steps below, you’ll end up with a shortlist of 2–3 converters you can trust, with clear pricing, realistic lead times, and a written spec you can hold them to.
Step 1 — Start with your “must-haves”
Before you speak to anyone, write down these five things:
Van type (e.g. VW Transporter / Transit Custom / Crafter / Sprinter)
Sleeping (how many berths? fixed bed or rock-and-roll?)
Cooking (gas, diesel, induction hob, or portable?)
Toilet/shower (yes/no, cassette, wet room?)
Usage (weekends only vs full-time touring)
Why this matters: you’ll instantly avoid converters who “only do” one style and try to push you into it.
✅ Tip: if you’re unsure, decide your non-negotiables (max 3) and keep the rest flexible.
Step 2 — Build a shortlist (don’t start with “who’s cheapest”)
Make a shortlist of 5–10 converters to contact. Use:
Their portfolio / Instagram (real builds, not stock photos)
Reviews (Google, Facebook, forums)
Recommendations (but still do your checks)
Red flag: brand-new pages, no workshop photos, no customer handovers, and no clear location.
Step 3 — Check they’re a real, trading UK business
Do these basic checks before you travel or pay anything:
Company details: are they a Ltd company or sole trader? Does the name match invoices and bank details?
Registered address: does it exist and match their website?
How long have they been trading? (new businesses aren’t automatically bad, but you need extra caution)
What you want: consistent details across website, invoice, bank account name, and social profiles.
Step 4 — Ask to see the workshop (and what’s in it)
A proper converter should be comfortable showing you:
The workshop space
Current builds in progress
Storage/security for customer vehicles
Tools and work areas (wiring bench, carpentry area, etc.)
Green flags:
Tidy wiring on current builds
Labeled parts / organised storage
They can explain what they’re doing and why
Red flags:
“We work from a unit but can’t show you”
No builds in progress
Everything feels temporary or rushed
Step 5 — Ask for a written spec (this is where most problems start)
Before you pay a deposit, you want a written spec that includes:
Layout + furniture
Bed type, upholstery type
Cabinet material + finish
Flooring type
Electrical
Battery type and capacity (Ah)
Charging: split charge / DC-DC / solar / mains charger
Fuse protection and where it’s located
What 12V and 230V circuits you’ll have
Gas (if used)
Bottle location
Regulator type
Ventilation and drop-out vent
Gas test on completion
Water
Fresh and waste tank sizes
Pump type
Where tanks and pipes are located
Heating (if used)
Heater make/model
Fuel pickup method
Control location
Safety cut-offs
If it isn’t written down, it’s not included.
If they say “we’ll sort that later” — insist it goes in writing.
Step 6 — The “10 questions” you should ask every converter
Ask these and compare answers side by side:
What’s your current lead time and what makes it change?
Who does the work — employees or subcontractors?
Can I see 2–3 current builds in progress?
What’s included in the price — and what’s not included?
What’s the deposit, and is it refundable?
What are the stage payments, and what do they relate to?
What warranty do you offer and what does it cover?
What documentation do I get (wiring diagram, manuals, certificates)?
Can I speak to one recent customer (not just a review)?
If something goes wrong, what’s your process for fixing it?
Green flag: calm, clear answers and willingness to put it in writing.
Red flag: pressure, vagueness, or “trust me mate”.
Step 7 — Understand deposits and stage payments (avoid the big trap)
A safe structure looks like:
Small deposit to secure a slot
Stage payments tied to milestones (materials ordered / build start / major stage complete)
Final balance on handover after snagging
Avoid:
Large upfront payments with no milestones
Cash-only requests
“Bank transfer to my mate’s account”
No invoice / no written agreement
✅ Minimum: always get an invoice/receipt that matches the business name.
Step 8 — Get warranty in writing (and keep it realistic)
Ask:
How long is the warranty?
What’s excluded?
Does it cover labour + parts?
Does it cover leaks, electrical faults, rattles, trim failures?
Reality check: Some components have their own warranties (fridges, chargers etc.). You want the converter to handle issues, not bounce you between manufacturers.
Step 9 — Handover day: snagging checklist (don’t rush this)
On collection day, test:
Every light, USB, socket, switch
Water pump, taps, leaks under the sink
Heater start/stop and fuel smell check
Pop-top (if fitted) and seals
Doors, drawers, catches
Charging from alternator, solar and mains (if fitted)
Bring: a phone charger cable, a kettle/plug-in tester (if you have 230V), and 30–60 minutes of time.
Step 10 — Trust your gut, but verify with evidence
If anything feels off — rushed communication, missing paperwork, shifting prices, unexplained delays — pause.
There are great converters in the UK. A good one will never pressure you to pay money before you’re comfortable.

F.A.Q.
What deposit is normal for a van conversion in the UK?
There isn’t one fixed rule, but most converters ask for either a small holding deposit to secure a build slot, or a percentage deposit before ordering materials. A sensible deposit should match the converter’s real costs and risk (booking labour time and ordering parts), not just be a big upfront payment “because”. If you’re unsure, ask for stage payments tied to milestones and always get an invoice/receipt.
Should I insist on a written spec before paying deposit?
Yes — always. A written spec is what prevents misunderstandings later (“I thought that was included…”). It should list the key parts of the build (layout, electrics, heating, windows, roof, upholstery, etc.) and what brands/models are being used where relevant. If it isn’t written down, assume it’s not included.
What’s a realistic lead time for a conversion?
Lead times vary massively depending on the converter, the season, and how complex your build is. Some converters are booked months ahead, especially for pop-tops and full electrical systems. A good converter will give you a realistic window and explain what could affect it (parts delays, previous builds overrunning). Be cautious of anyone promising an unusually quick turnaround without explaining how they can do it.
What are the biggest red flags with converters?
They won’t provide a written quote/spec, or everything is vague.
Pressure to pay quickly, or big deposits with no clear milestones.
Payment requested to a different name than the business on the invoice.
No workshop address, no builds in progress, or they avoid showing their work.
Constantly changing price/lead time without written updates.
What warranty should I expect?
You should expect a clear warranty for workmanship (fitting, leaks, rattles, trim, wiring faults) plus separate manufacturer warranties for individual components (fridge, heater, chargers, etc.). The key is getting it in writing: what’s covered, how long for, and how issues are reported and fixed. A reputable converter won’t disappear once the van is collected — they’ll have a straightforward aftercare process.
Should I view the workshop before paying a deposit?
deally, yes. Seeing the workshop (or at least a proper walkthrough video) tells you a lot: whether they have real space to work, how organised they are, and whether there are genuine builds in progress. It’s also a good chance to judge the quality of their work up close — especially wiring, finishing, and how tidy/secure customer vans are stored. If someone refuses to show anything at all, won’t confirm an address, or makes excuses every time, treat that as a red flag and slow down.
