Anglian is the UK’s biggest name in windows – a position we think it deserves. We’re so impressed by its product range and customer feedback that we named it the UK’s best double glazing installer.
Anglian Home Improvements, to give the company its full name, has been around for much longer than most firms we feature here at the Eco Experts. It has spent 60 years blazing a trail for products and ideas that have made the UK’s homes far more energy efficient.
Read on for a closer look at Anglian’s windows and other ranges, and to discover what its customers say about its prices, products and installers.
What type of double glazing do you need?
Get startedAnglian overview
Anglian Home Improvements launched in Norwich in 1966. It led the way in double glazed windows, which are among the most important home sustainability innovations of the 20th century.
Solar panels and heat pumps may seem more obvious eco installations, but double glazing transforms your home’s energy efficiency. Reasons to install double glazing include lower heating bills, a more valuable property and a smaller carbon footprint.
Anglian’s window range grew quickly to become the best in the industry. Whether you want to upgrade your beloved sash windows with classic wood frames or install low-maintenance new uPVC replacements, Anglian will have your needs covered.
The brand’s catalogue now extends far beyond windows. Anglian’s teams build and install doors, conservatories and rooftrim (guttering, fascias and so on). We’ll take a closer look at these products below.
How good are Anglian’s windows?
Anglian’s windows come in an unbeatable range of frames, shapes and finishes – and they’re all made to measure.
You can choose from all the standard window types including casement, bay, tilt-and-turn and sash, along with many less familiar styles. The teams will craft custom shaped frames and cottage windows to meet tight rules in conservation areas and listed buildings.
Most window types are available with most frame materials. You can get casement and bay windows in uPVC, timber and aluminium; flush, cottage and sash windows in uPVC and timber; and tilt-and-turn windows in uPVC. Most come in a range of colours, and there are various options for etched and obscured glass.
Anglian offers both triple and secondary glazing as well as double glazing. See our guide for more on the pros and cons of double vs triple glazing.
The company’s website has some excellent free tools to help you visualise various window types on your home. There’s also an inspiration gallery, and a thorough guide to home renovation.
You might expect such an impressive range to come with hefty price tags, but Anglian’s prices are excellent compared with the wider market. Its uPVC windows come with a price match guarantee, too, so you know you’re getting a good deal.
What other products does Anglian sell?
Anglian makes and installs far more than just windows. It also produces double glazed doors plus porches, conservatories, blinds, shutters and rooftrim. All products are made to measure for your home.
We’re particularly impressed by the range of doors, whose material options include composite, uPVC and timber. Besides front and back doors, the catalogue covers bi-fold double-glazed doors, sliding patio doors and French doors in a choice of frame materials and colours.
Made-to-measure blinds and shutters are relatively new arrivals in the Anglian range, and feedback has been very good so far. After all, it makes sense to have your window dressings made by the same company that produced your windows.
What guarantees does Anglian offer?
Anglian’s windows are made in Britain to the highest industry standards. PVCU products get a 10-year guarantee on parts and labour, and there’s a 15-year guarantee on glass sealed units. Doors, conservatory frames and cylinder locks also come with a 15-year guarantee.
To ensure standards in products and installation, the company became a founding member of FENSA (Fenestration Self-Assessment Scheme) in 2002. FENSA was established to ensure that window installations comply with building regulations, are energy efficient, and are registered with the local council.
Anglian is also accredited by the BFRC (British Fenestration Rating Council). Founded in 1997 to ensure standards, the BFRC is now Europe’s most widely-used windows rating system. Under this system, Anglian’s windows have ratings ranging from B to A++.
What do Anglian’s customers say?
Anglian receives a score of 4 out of 5 from customers on Trustpilot, from a huge volume of reviews – more than 37,000 at the time of writing. Just under 75% of reviewers give four or five stars, with the huge majority giving the maximum five.
Even when negative reviews appear, Anglian responds quickly and constructively. Customers who’ve gone ahead with their installations are, by and large, delighted.
