JML Contracts

JML Contracts is an award-winning, family-owned building and civil engineering company, specialising in house building using Structural Insulated Panels (SIPs).

With over 25 years’ experience, we are proud to offer innovative, sustainable and energy-efficient solutions to private and commercial customers across the UK. We have forged an enviable reputation for designing and engineering high quality SIPs kits.

We are leaders in our field, offering exceptional thermal performance, airtight and draught free constructions. Building with SIPs offers significantly reduced heating and energy bills, off-site manufacture techniques, minimal site erection time and increased habitable roof space due to buildings not requiring trusses. We can build anything from a small extension or bespoke family home to a social housing development.

Our comprehensive design service includes our in-house Passivhaus-certified SIPs architect who works alongside engineers, project management and installation teams. Our supporting civil engineering division enables us to tailor a complete construction package for our clients. We are experienced in carrying out complicated groundworks including those on steep inclines, in close proximity to watercourses and in awkward to reach locations.

We are one of the only companies in the country that can develop and facilitate a package like this to ensure our clients’ developments are fully project managed from concept to completion.

In October 2017, our SIPs factory featured on an episode of Grand Designs. The client approached us to engineer a SIPs kit for his tiny 9.5m x 4m East London plot. Planning was granted for a cleverly designed ‘compact’ property, potentially the smallest two-bedroom house in London.  The owner chose to build his home using SIPs to achieve Passivhaus standards and deliver exceptional thermal performance.

We believe that building with innovative products like SIPs is the future for housebuilding in the UK. Using cutting edge design and manufacture techniques, SIPs present the ideal solution for those looking to build the highest quality of sustainable new homes.
