Build budget worksheet
Fill in amounts from your own quotes. Nothing is pre-filled because prices vary by country, vehicle and date. Entries are stored only in your browser.
Why we don't publish an "average van build cost"
Prices change constantly and vary by country, vehicle and supplier. A single number would be guesswork – so instead, this worksheet makes sure you price every category yourself from live quotes. Your entries stay in your browser; nothing is sent anywhere.
Categories most often forgotten
- Fuses, busbars, cable lugs, crimping tool and heat-shrink
- Sound deadening before insulation
- Sealant, rivnuts, primer and rust treatment
- Professional checks (gas, electrical, heater installation, weight/inspection)
- Insurance changes and vehicle re-registration where applicable
- Tool purchases or rental
Work through the systems in order with the van build gear guide.
Frequently asked questions
How much does a van conversion cost?
It varies enormously with the vehicle, region, DIY vs professional labour and the systems you choose. Rather than quote an average that won't match your build, list every line item and price it with real quotes.
What is the most expensive part of a van build?
After the vehicle itself, the electrical system and professional labour are usually the largest items, followed by heating, windows and cabinetry.
Should I add a contingency?
Yes. Builders routinely discover extra parts, tools and fixings. A contingency line of 10–20 % of the build budget is a common planning rule.
