LK Armatur and Certatherm join forces to strengthen distribution in Great Britain

LK Armatur has appointed Certatherm to distribute its full range of heating components across Great Britain. The partnership combines Swedish manufacturing expertise with local technical support, training and a commitment to specialist heating merchants.

The agreement builds on a long history of working together and gives the two companies a shared focus: helping merchants and installers deliver reliable heating systems, backed by dependable products and accessible expertise.

Certatherm’s team brings more than 20 years of experience in the heating sector, spanning distribution, system design, technical consultancy and installer support. Its experience also includes involvement in industry technical committees, MCS working groups and the development of heating standards.

Supporting merchants and maintaining continuity

Supporting LK Armatur’s existing merchant network is central to the partnership. Certatherm will work with current stockists while developing new relationships with specialist heating merchants across Great Britain.

Tony Lovell, who has represented LK in the UK for many years, will continue working with existing customers and developing new merchant partnerships alongside Certatherm. He will work closely with Martin Boyle, UK Sales Director, and Jamie Bennett, Technical Director, combining established customer relationships and product knowledge with Certatherm’s technical and commercial resources.

The partnership will also bring further investment in product knowledge, training and technical support to help merchants advise their customers and installers select, fit and commission LK products.

Magnus Eriksson, Managing Director at LK Armatur AB, says:

“LK Armatur has chosen to build on its relationship with Certatherm because we see a strong strategic fit between our respective capabilities. LK brings proven hydronic products, technical expertise, and extensive experience from European heating markets, while Certatherm contributes valuable knowledge of the British market, established industry relationships, and strong capabilities in technical training and local market development.”

Reliability where it matters

For installers, component reliability has practical consequences. A failed valve can mean a return visit, time spent diagnosing and replacing parts, and disruption for the homeowner.

LK Armatur has built its reputation on well-engineered, dependable components designed to perform reliably over the long term. For example, its diverter valves have a reported failure rate of just 121 per million units, demonstrating the importance placed on product quality and reliability.

That focus on dependable components underpins the companies’ shared philosophy: Do it once. Do it right.

Sune Nightingale, Co-Founder of Certatherm, says:

“Good heating systems depend on getting the details right. A relatively small component can make the difference between an installation that works reliably for years, and one that causes repeated problems.

“We want to help installers get better results, more easily and reliably, so they can finish a job knowing it's been done properly and get on with the next one.”

Experience from the installation site

Established LK brand champion Aventus Eco, the multi-award-winning renewable heating business, continues to expand in Scotland, with LK components forming a key part of its heat pump installations.

Sean Hogan, Owner of Aventus Eco, says:

“We started using LK diverters around a year ago, and are now using them on our heat pump installations every single week. We’ve genuinely never had a single issue with one. The high Kv value, reliability and ease of servicing are exactly what we’re looking for when designing our systems, and they’ve proven themselves time and time again.

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.”

By bringing together dependable components and knowledgeable local support, LK Armatur and Certatherm share a clear ambition: to help installers get the job right first time.

Do it once. Do it right.
