I decided to engage with Solarcrest following initially seeing them at a show, doing more research and looking at alternative providers. The work they have already completed includes OpenCell foam insulation of both the roof and the floor, the work I have yet to be completed is for MVHR (Mechanical Ventilation Heat Recovery). When consulting with Solarcrest and the Project Team, they have always been ready and available to discuss needs, offer advice and ensure the most effective product is delivered to match budget. The Project Team pride themselves (and rightly so) in engaging with the Builder, Building Control, and Trades to ensure all the ducks line up and all the necessary infrastructure is in place when it needs to be in place throughout the project. Contacting Solarcrest and The Project Team is always fast and efficient be it a telephone call or via email, they are always there ready to answer your concern or query. The installation of the MVHR is still ongoing and is approached on a build phase basis, I have zero doubt when the remaining phase and commissioning are complete I will not be disappointed with either the performance or outcome. As with this type of intallation, it is imprative all the necessary documentation and certification is evident for production to Building Control, Surveyors and postentially future lenders. As my installation is not yet complete, I do not have mine, but I know it will be forthcomming and on point following the project being complete. When you receive the documentation, it should be treated like gold and safely retained. In summary, albeit my project is still ongoing, I have every confidence in Solarcrest, the advice given (and ongoing), the communication, the Project Team, the installers (who are fantastic by the way), the products supplied (to date) and the warraanties / documentation that will be provided. I'm suree you will not be disappointed in choosing Solarcrest.
