Selling your home and need CCC?
Undertaken building work without a consent and now need that certified?
Based locally in beautiful Marlborough, our goal is for you to receive your Code Compliance Certificate on older, partially completed building consents. We also assist with identifying Certificate of Acceptance requirements and providing options for achieving this.

andrew De La Mare16/10/2025 I recently engaged Gavin from Harding Consulting to obtain a Certificate of Acceptance (CoA) to convert a recreational space into a studio flat I built inside a steel shed, and I couldn’t be happier with the experience. From start to finish, Gavin made the entire process completely stress-free. His knowledge of council requirements and attention to detail were outstanding, and he handled everything with professionalism and efficiency. What really stood out was how easy he made what could have been a complicated and frustrating process. Thanks to Gavin’s expertise and clear communication, everything went smoothly and successfully. I highly recommend Gavin and Harding Consulting to anyone needing help with building consents or CoAs. A truly fantastic service! Keri Maslen30/08/2025 We needed to get a code of acceptance for our conservatory and we were told it could take months to be done. Gavin was recommended to us and it only took him a few days to complete. Gavin went over and above for us and we would highly recommend him to anyone needing a consultant in the building industry. What a team!! Thank you very much Gavin and Caroline. G T14/04/2025 Excellent service, super fast and highly competent advice all the time. Gavin and Caroline constantly exceeded my expectations. Karen Lambert10/04/2025 I got Gavin’s phone number for Harding Consulting and contacted him regarding an issue for what I was told was an unpermitted portion of my house. He responded to my text immediately and we spoke the following day during business hours. After meeting him and going over my problem he went away to work on it for me. Within half an hour he called with good news and emailed his professional findings within the hour! I could never have navigated this on my own - his expertise, honesty, professionalism and work ethic are second to none. I will highly recommend his services to anyone who needs help navigating building legislation. Thank you so much Gavin and Caroline, you are the best. Karen L :-) Chris Mears10/12/2024 I recommend Gavin 1000%. In 2017 we undertook the biggest challenge of our lives subdividing and building our own home. After project managing the whole build by 2019 we moved into our new home exhausted from the challenge of dealing with contractors and council. Both were very 50/50. Next thing covid hit and before I knew it we’d been in our home for 4 years with no code compliance certificate. We’d had our final inspection and had 3 small things to finish but I just muster the motivation to chase the last producer statements from the several difficult or disorganised contractors and litany of paperwork that needed to be provided to get everything across the line. In late 2023 I found out about Harding Consulting and felt like I’d stuck gold. I contacted Gavin and explained our situation. Gavin took control, systematically working through the items required to get our CCC. I can not praise him enough. Where I would have wanted to cause physical harm to some of the stubborn individuals needing to be dealt with, Gavin was calm and resolute, holding his ground and siting the code and relevant precedents to move things forward. We finally have our CCC and better still my sanity. One of the best things from my perspective is this was all done by Gavin in Blenheim dealing with Auckland Council. It doesn’t matter where you are in the country if you need a consummate professional to help you navigate the challenge of consents or compliance - Gavin is the man you want to deal with! Alex Smith07/10/2024 We just used Harding Consulting to get a Certificate of Acceptance for a non- consented sleep out we inherited with a home purchase. Everything Gavin Harding said would need to happen, happened when it said it would, a super efficient process, he used a responsive network of skilled tradespeople. Cost just a little less than he said it would. Great service. Good value. Thank you. Andrew Stowell19/08/2024 Gavin was amazing. It was just great finding him and getting such great help and support through the maze of issues we found ourselves in. Best money spent in a long time. G P18/08/2024 I found this service to be extremely professional, efficient and organised, and able to deliver an excellent result in bringing tradesmen, contractors and MDC staff together to complete compliance tasks and council certification within a tight timeframe. I would thoroughly recommend Gavin and team to prospective customers. Graham Payne Blind River - Marlborough Joy Moseley15/05/2024 Thank you to Gavin Harding who made the whole process of acquiring a COA for my ensuite less stressful. He was very professional and always kept me up to date with the process. Would highly recommend his services to anyone.Load more
