Acorn Windows London

I started Acorn Windows in 1989 and we have since become a well-established local company.  We have built an enviable reputation for installing quality products at sensible prices in UPVC, Hardwood or Aluminium and providing an excellent after-sales service.  With over 7,000 installations, primarily in South East London, South West London and Kent, our aim is to make your experience stress-free from your first contact with us through to the completion of your installation and beyond.

We never employ salesmen, preferring to have one of the company partners, with a trade background, attend each appointment.  Therefore, you will not experience pressure selling or silly pricing structures.  You will get the bottom-line price first time.

We incorporate your own ideas and, if required, we are able to offer expert advice on design, together with guidance on building regulations, ensuring your windows, doors or conservatory will be sympathetic to your home and compliment the surrounding area.  We can provide examples of our existing work to help you visualise the best configuration to suit your home and budget.

In any street, you may see examples of poor design and the detrimental affect it can have on your home.  Our expertise and 22 years of experience will ensure this will not occur should you choose Acorn Windows as your preferred installer.

Acorn Windows is a member of the Consumer Protection Association (CPA), which receives feedback from every customer for whom we undertake an installation.  This information is available to potential customers on request.  The CPA also insures your guarantee for 10 years and provides a deposit protection insurance scheme, and both of these benefits are automatically provided on the placing of an order with Acorn.

We are also Certass accredited so, when your installation has been completed, it is automatically Fensastration-registered to confirm that everything conforms to Building Regulations.

If you would like a stress-free appointment with me to discuss your requirements and get some helpful advice, as opposed to ‘sales-speak’, drop me an email at or give us a call on 020 8850 4750.
