From the products we manufacture to the installation and customer services we provide, quality remains the hallmark of John Williams.

We remain one of the few companies to hold the British Standards Institution award for manufacture and customer care.

For even greater assurance, we hold no fewer than four Kitemarks - nationally recognised seals of approval - for the quality of our products and their excellent energy ratings.

And as a member of FENSA, you are safe in the knowledge that our replacement windows and doors comply with the current Building Regulations for both England and Wales.

With our products made, supplied and fitted using in-house resources, we operate stringent quality control and testing at every stage.

In this way, John Williams can maintain such high standards, and reward our customers with the very best service.

To build on or change the use of land or buildings, UK law requires you to obtain planning permission. John Williams will assess your location and individual Veranda Glass Extension design against current planning policies and guidelines to establish if planning, listed building or conservation consent is required.

Where approval is required, full plans will be prepared and submitted to your local authority by John Williams and we will handle the planning consent process on your behalf.

Depending on your circumstances, you may also require Building Regulations, Building Warrant (Scotland), Water Authority, Estate or Party Wall approvals.

In the unlikely event that you require any of these further approvals, John Williams will expertly handle all the matter on your behalf, so your project proceeds as smoothly as possible.

Failure to obtain the correct approvals could lead to you having to tear down your Veranda Glass Extension (at your own expense) and create legal problems when selling your home.

With John Williams you can rest assured you will avoid any of these costly and distressing errors.

One of the additional benefits of John Williams conservatories is the use of high quality roofing materials designed to keep heat in throughout the winter and prevent heat building up in the summer. What it means for you is a room that enjoys all the glories of summer warmth and winter cosiness as this room will be comfortable whatever the season.

You might decide to opt for our solar glass panels that do just this by cleverly stopping heat building up in the summer and stopping heat losses in the winter.

Or you might decide to try out polycarbonate roofing which is able to reflect 80% of the sun’s energy away from the roof and cleverly in the winter it also radiates rising heat back into the room to keep your Glass Veranda Extension nice and snug.

So when you choose this stylish contemporary way of living, where indoor meets outdoor, you can also enjoy the peace of mind in knowing you’re doing your part for energy conservation.

Design your dream conservatory with us and we can talk you through all the roofing options and decide what best suits your needs. Whatever you decide upon, our specialist roofing material is of the highest quality and comes with a 10-year guarantee.
