This organisation is a waste of space

This organisation is a waste of space. I had a heat pump installed by SWS Northwest, which failed to heat the house as the heat loss calculations where all wrong. This organisation completely sided with the installer. They even refused to help with the ADR process, even though SWS broke their own contract by refusing to go to ADR.
Completely biased in favour of the company, couldn’t careless about the customer.

Well worth going with a local supplier

The process was pretty painless and installation completed in two days. The team were courteous and good humoured.
Well worth going with a local supplier, who also beat bigger suppliers on price.

We are extremely pleased with the service provided by Broden. From start to finish, the installation was carried out to the highest standard by a highly experienced, professional, and courteous team. They worked efficiently, kept our property clean and tidy throughout, and were always respectful of both our household and our neighbours.

The quality of the workmanship was outstanding, and the entire process was completed with great attention to detail. We would not hesitate to recommend Broden to anyone looking for a reliable and professional company. Thank you to the whole team for an excellent job

I’m very happy with the installation process. The staff (Sham I think his name is) who first attended to market the product was very knowledgeable. The whole process went very smoothly and installation was done and completed with the solar working straight away. The engineer was very good and nice, as well as the guys who installed the panels.

Although Project Solar was more expensive than the other providers I contacted, I am pleased with their work.
I am particularly impressed at how quickly they helped in setting up the SEG for solar exporting and importing, and within 4 weeks, this was up and running. Thank you 🙏🏾
