About us

Plumb-Line was established in 1987 and has grown steadily by recommendation since then. Originally supplying and installing traditional forms of central heating, such as gas, electric and oil, we recognised the growing importance of more sustainable and renewable forms of heat and energy. In March 2012 Plumb-Line was one of the first central heating installers to become MCS accredited. MCS is the Microgeneration Certification Scheme, an internationally-recognised quality assurance scheme for small-scale generation of renewable energy. MCS accreditation gives Plumb-Line a mark of competency and demonstrates that we can install to the highest quality every time.

Plumb-Line supplies and installs various types of renewable heating systems:

• Biomass 

• Air and ground source heat pumps 

• Solar water heating 

• Solar Photo Voltaic (Solar PV) energy 

• Hybrid systems

Based in Moulton Park, Northampton, we work throughout Northamptonshire as well as the Midlands, East Anglia and the Home Counties. We are large enough to benefit from economies of scale and have the capability and professionalism to deliver a quality service at a reasonable price, but small enough to cater for the needs of individual customers.
