Conversion Build Budget Estimator
Get an order-of-magnitude estimate of what a van conversion is likely to cost, from van size and the level chosen for insulation, electrical, water, heating, furniture and homologation. This is a rule-of-thumb planning range aggregated from published build-cost guides — never a quote, and not tied to any supplier. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorCable & Inverter Sizing Calculator
Work out the cable cross-section, fuse rating and inverter sizing a DC circuit needs, from the load, run length and acceptable voltage drop. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorEV Range & Charging Cost Calculator
Correct a manufacturer WLTP range figure for the load, elevation and weather an electric campervan actually sees, and estimate the cost of charging it. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorHeater Fuel Runtime Calculator
Estimate how long a diesel or gas (LPG) van heater will run on a tank or bottle, from the heat output you actually use. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorLow-Emission Zone Eligibility Checker
Check whether a diesel campervan is likely to be let into a country's low-emission zone scheme, from its Euro emissions standard and total weight. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorOff-Grid Battery Bank Sizing Calculator
Estimate the leisure battery capacity an all-electric van needs from your daily energy use, the days of autonomy you want, and your usable depth of discharge. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorPayload & Driving Licence Calculator
Work out how much payload is left after a conversion — kerb weight, build-out, water and passengers all eat into the GVW — and see which driving licence category that GVW puts you in. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorVan Solar Array Sizing Calculator
Estimate the solar panel wattage a van needs to cover its daily energy use, from your peak sun hours and realistic system losses. The maths runs entirely in your browser — nothing you type is sent or stored.
Read → calculatorWater Autonomy Calculator
Estimate how many days a van's water system will last — and whether the fresh water tank or the grey/black waste tank runs out first. The maths runs entirely in your browser — nothing you type is sent or stored.
