About Us

Established in 2007 as Maincor Limited, we are based in Lutterworth, Leicestershire, supplying customers throughout the United Kingdom.

We are part of Wienerberger Ltd who are an international provider of building materials and water and
energy infrastructure.

We specialise in innovative plumbing solutions and underfloor heating, using primarily multilayer composite pipe (MLCP) and we also have a PE-RT product option available. We are especially proud to have introduced Austroflex AustroPUR Pre-Insulated Pipe to the UK; an ideal solution for minimising heat loss in underground applications such as District Heating projects. We have a product range to suit most requirements from large commercial projects such as schools and hospitals to new build housing developments through to small conservatory extensions.

Our products and systems have the required UK WRAS approvals and many also have international approval. We are a supporter of BEAMA (British Electrotechnical and Allied Manufacturers Association) and work with CIBSE (Chartered Institution of Building Service Engineers), BSRIA (Building Services Research and Information Association), IDHEE (Institute of Domestic Heating & Environmental Engineers) and CIPHE (Chartered Institute of Plumbing Engineers).

Why Choose Maincor

Delivering high quality customer service is the number one priority at Maincor, offering unrivalled technical support, delivery into the market place, and new product innovation.


Innovation is at the heart of everything we do. Maincor in Germany have won Top Innovator awards, filed numerous patents and works on constant improvements to the product range. In the UK our latest developments are a range of underfloor heating systems specifically for retrofit applications and the introduction of flexible pre-insulated pipe. In 2017 we were 10 years old in the UK, there’s more every year and still plenty more to come.


Our team has experience back to the very roots of multilayer pipe systems in the UK and supports the CIBSE standards for the design and installation of plumbing, central heating and underfloor heating. We also have a resident renewable energy specialist to ensure that systems are correctly designed to give the best performance. This expertise enables us to advise our customers on the best way to use Maincor products in any project to meet your requirements and exceed your expectations.

We are well-networked. We are supporters of BEAMA (British Electrotechnical and Allied Manufacturers Association) Underfloor Heating Forum; we are a member of BSRIA (the Building Services Research and Information Association);  and supply a member to the CIBSE Domestic Heating Design Panel (Chartered Institution of Building Service Engineers). We have also supplied occasional representatives to the Government’s Industry Compliance Forums for developing building regulations and the Green Deal.

Our technical department qualifies its advice and training by adherence to the HNC Building Services Engineering Standard, CIBSE design guides and the BPEC (British Plumbing Employers Council) underfloor heating training courses.


Our first rate technical support ensures that help is available every step of the way; from quotation, material schedules, drawing and full design, through to visits on site and installer training. We have some of the shortest quote turnarounds in the industry and if you’ve got an emergency, we can respond immediately – our service starts as soon as you call. To ensure that our customers receive the best service, all of our phones are answered by one of our highly trained staff not an automated system. We know how important the personal touch is.


Our products are among the highest quality in the industry and we are so proud of our factories that visitors are always welcome. Our multilayer pipe is formstable, has the lowest expansion rates of any plastic pipes and meets the high standards of approval for the UK. We are particularly proud of our press fitting range which offers unrivalled quality with its unique ‘D’ sealing ring.

We pride ourselves in offering reliable products and our 10 year insurance backed warranty – which covers consequential damages – is superior to many leading brands reflecting our real confidence in our products.

This is further supported by our Product Replacement Guarantee, in the event of a manufacturing fault we will provide replacement MLCP and fitting products for up to 50 years.
