Workshop Pricing
The prices for our Campervan conversion services are clear and transparent — designed to help you get exactly what you need.
Our workshop services are charged at a simple, fixed labour rate of £55 per hour + VAT, plus any parts or materials used. Every job is logged through our time-tracking system, so you can see exactly what was done, how long it took and what components were fitted — no surprises, no guesswork.
Whether it’s fault-finding, wiring upgrades, finishing work on a self-build or installing new kit, the aim is always the same: high-quality workmanship, done properly, at a fair price.
