Really appreciste thecservice from all at Mark1 conversions as they add a Reimo hightop roof to our van. They talked through all aspects of what we wanted, before putting together a detailed quote. They have then coped with nervous cutomers watching on as they cut a hole in the van roof! Thanks all. Looking forward to seeing the finished product.
Had some leisure battery issues resolved and new solar panels fitted on my van. Brilliant service, really helpful and patient explaining how to get the best out of the new battery. I imagine their conversions to be 5* and if I ever change my van I know where to go. Thanks so much.
Mark1 conversions were very accommodating, knowledgable and reliable. Carried out the replacing of my solar panel and completed my gas cooker testing. I would have no hesitation recommending them to anyone. Thank you!
Just had our Citroen relay converted by Lee and the team at Mark 1 and we are so pleased with it. The standard of work is first class. They were very accommodating with what we wanted and kept us updated all through the process. If you’re looking for a conversion company look no further.

A fantastic conversion of our Boxer van by Lee and the team. Responsive from start to finish with updates and photos along the way. We are delighted with our van which is everything we could have hoped for and we are so much looking forward to living in it for the next three months. A quality company with first class customer service.

Absolutely great job, even when they just about squeezed me in, which was amazing! Fitted my electric, couple weeks later had an issue with the lights which they fixed incredibly quickly! Couldn’t recommend them enough and will be back soon for some more work in my van.
I can highly recommend Mark 1 Conversions, they've done a fantastic job fitting a Skyline pop top to my VW T6, a leisure battery, 240v electrics, fully carpeting inside and also a diesel heater as well. They've been really easy to deal with, on budget and on time too, no need to look anywhere else!
I had my windows fitted here for my van. A very professional set up and extremely helpful. I can't recommend them enough.
