We are pleased to announce a new distribution partnership with Certatherm, covering our full product range in Great Britain. Building on our long history of working together, the partnership combines our Swedish engineering expertise with Certatherm’s local market knowledge and technical support.
Certatherm's team brings more than 20 years of experience in the heating industry, spanning distribution, system design and installer support. Together, we will support our existing merchant network and develop new relationships with specialist heating merchants across Great Britain.
For our existing customers, Tony Lovell remains a familiar point of contact. Having represented us in the UK for many years, he will continue working alongside Certatherm, supported by UK Sales Director Martin Boyle, Technical Director Jamie Bennett and the wider team.
The partnership will also bring further investment in product knowledge, training and technical support, helping merchants and installers get the most from our range.
Our established brand champion Aventus Eco, the multi-award-winning renewable heating business, already combines our components with Certatherm's support in its heat pump installations across Scotland.
Sean Hogan, Owner of Aventus Eco, describes what that means in practice:
As Aventus Eco continues to grow, it’s important that we have products we can trust and good people behind them. Certatherm have been absolutely brilliant, always at the end of the phone if we’ve needed anything. Having that level of support, along with a product that just does what it’s supposed to do, makes a massive difference to us as installers.
Together with Certatherm, we want to bring that combination of dependable components and knowledgeable local support to more merchants and installers across Great Britain, helping them get the job right first time.
Do it once. Do it right.
