I’ve recently had my brand new Transporter T7 carpet lined and LED spot lights fitted. Karl was incredibly easy going and walked me through the entire process step by step, taking the time to make sure everything was exactly how I wanted it. From explaining the carpet colour options to showing how the finished result would look. I ended up spending a bit more than I originally intended, but it was worth every penny considering how good the final result turned out. Thank you to Karl and the whole team at Customhaus. Pictures don't do it justice !

I had the existing bed replaced with a new design and extra cupboard doors put in. The staff were a pleasure to deal with going above and beyond. They listened and took on board what was important to me and went with that. Their attitude and work is excellent. I would highly recommend.

Where do I start !! My partner and I initially ( we thought) just needed a paint job on a really poorly painted pop up roof. When you get to meet the team, see first hand the quality of the workmanship and realise you’ve just discovered people and a place you can trust with everything!!! So, our list of jobs and fixes suddenly expanded greatly and they ‘fix list’ process was as easy and as flexible as they come with an online system that allows absolute control . Karl, Kirsty, Tara and Yolanda stayed in constant touch throughout, and for our own peace of mind, we actually asked for even more work to be be reviewed and sorted and all promised by the team , and still within the same time window for completion. The Team, the standard of work , the communication, and the final results were exceptional, all of which leaves us in no doubt whatsoever as to where we will go for all future work or a new chapter. We cannot recommend CustmHaus highly enough, or even properly articulate how good these guys really are. So a huge and sincere thank you !!!! Dan and Emma

I can’t thank Karl & his team enough for sorting out the electrical install on my T6.1 Camper. I bought the Camper New in 2020 from a company in Bristol, to cut a very long story short one of my Lead Acid Leisure batteries blew up luckily I wasn’t driving it at the time!! as it was under the drivers seat. Very poor wireing was exposed & was agreed with Karl to re do the lot after a major Acid clean up. I now have a complete Lithium set up & First class work! + They fitted me in before our holiday 😊👍🤙🏻

Over the moon with my Streamline slimline pop top fitted, great communication and advice from Karl and the team would highly recommend as the smile on my son’s face was priceless. Cheers Drew.
