Window & Door Showroom


We’ll always be honest with you. We never inflate our prices just to offer an artificial discount. With us, what you see is what you get: fair, professional, and courteous.

Our teams will listen to what you need and do their best to find the best solution – at a pace and price that’s comfortable for you. You see at Planet, we always put you first.

You want to be sure that your new home improvement complies with Building Regulations, and so does the Government.

That’s why every window and door installation or replacement in England and Wales must now be registered as reaching the standards set by the Government’s Building Regulations. If you were to have work carried out that did not comply with Building Regulations, the installation would not be legal and could cause significant problems when you come to sell your home. Don’t worry – you don’t have to do anything. Planet will do it all for you through Assured Certification am authorised self-certification body.

Assure Certification

When it comes to improving your home with new windows and doors, it can be a daunting task to find a company that you can trust. Choosing an Assure-certified installer to complete the work means you can rest assured that the installation complies with Building Regulations and is therefore legal and correct. You will be even be sent a certificate to prove it. This should arrive within 28 days and proves that the work is registered with the Local Authority

All installers and surveyors registered with Assure will be provided with branded ID cards so you know they are exactly who they claim and they have the appropriate Minimal Technical Competences (MTC’s) to complete the work on your home.


Our portfolio of windows, doors and living spaces will give you a glimpse into how you can transform your home with Planet. But for the complete Planet South Lakes experience, we’d love to invite you to our sparkling showroom in Kendal. There, you’ll find life-size installations and bundles of inspiration!
