Intergas
215+ Keywords ranking in the top 3 positions on Google
Having been led by its Dutch parent company, Intergas UK wanted to take control of their website and marketing push by bringing them both in-house. The ambition was clear: to lead the shift in modern heating, not react to it. To achieve this, they approached Sherbet Donkey to help launch a content-first digital marketing strategy, with a strong SEO focus on boilers, heat pumps, hybrid systems and servicing options, as well as on boosting training course bookings.

Early gains while laying the foundations for long-term growth
Intergas UK wanted to build their organic visibility early, knowing that demand for their hybrid systems and associated training would increase naturally. The goal wasn’t a short-term boost but consistent long-term growth across the sector.
Within just a few months, we were able to show measurable improvements across traffic, engagement and conversions. (July 2025 to January 2026 vs the previous period.)

From product supplier to solutions expert: turning expertise into authority
As a market leader in the Netherlands, Intergas fully understands the direction the heating industry is heading in the UK. Hybrid systems, heat pumps and energy efficiency are only becoming more important, and they wanted to be leading the conversation, not following it.
In supporting this direction, we began by implementing a content-first digital strategy built around thought leadership, not just describing products. This has seen us create authoritative and genuinely useful content across Intergas’ wide range of traditional boilers, innovative heat pumps, comprehensive servicing and installer training offerings. The aim has been to position Intergas as knowledgeable heating solution experts, and the results so far show that the strategy and skill we’ve brought to the project are working.
What we did to build authority and drive enquiries
Strong foundations for serious growth
By combining technical SEO fixes, a smarter structure and a serious investment in high-quality content, we gave Intergas the platform they needed to compete properly in the rapidly changing UK market. Once legacy structural issues were resolved, their new content began ranking quickly, and engagement followed.
Both Intergas and the team at Sherbet Donkey are thrilled with the speed at which the project has progressed so far, and that rankings and organic use of the site have significantly improved. We’ve now expanded the scope of our work with Intergas, as they’ve been so impressed with the results delivered to date. The foundations are in place. Now we keep building.
Client feedback:
“I could not recommend a better digital marketing agency. This is the second organisation in which I have chosen to partner with Sherbet Donkey, and they remain my agency of choice. I will continue to recommend them without hesitation.”
