Why choose a double-glazing business?

Let’s start with a few eye-catching double glazing facts. They prove it could be a great trade to get into.

According to the Glass and Glazing Federation, UK homes are the worst in Western Europe for heat loss. The Federation estimates that around 80 million home windows will need replacing* if we are to meet the government’s net zero carbon emissions target.

Double-glazing in properties also helps bring down energy bills. This all indicates that demand is rising for double glazing – and so are the salaries you can earn in the trade.

Demand for double glazing installation and repair is likely to come from:

  • New-build properties

  • Properties that already have double glazing which needs replacing

  • Older properties without double glazing that want it installed

Alternatively, you could include a location in your business name, so people know you’re local. Or why not go for a humorous name to really catch the eye?

Before you get too attached to a name, make sure it isn’t already being used by another business.

The next step will be to register your company name.
