HIU Breakdownandrepair's client portfolio now comprises some 6300 clients. Each client has a great working relationship with us and trusts us to perform first class HIU service and repair for their landlords and tenants.

With van stock readily available on various Heat Interface Units you can almost always rely on us to perform a first-time fix on our initial visit.

We have access to HIU plugin software for Caleffi Heat Interface Units, Evinox HIUs, Switch2, and Intactec Smart Heat Interface Units. The plug in software for these Heat Interface Units are a paramount asset required during breakdown and repair of these intelligent HIUs. Our HIU repair engineers have access to Heat Interface Units parameters, engineer’s mode, calibration settings, alarm list, granting them access to information that can only be ascertained when using the plug in software.

Accurate reporting is essential upon completion of any HIU repair, and our engineers will provide the office staff with an accurate digital report along with any pictures taken on site. This will then be emailed to the client for peace of mind.

Our HIU service engineers take pride in their punctuality. When attending Heat Interface Unit repairs in London we have an average SLA of 62 minutes from call to site, which is exceptionally quick for the sector.
