Zenith Windows Update

Are you looking for reliable installers to install new windows or update to double-glazed ones?

You may have considered Zenith Windows (or Zenith Staybrite), which was one of the largest glazing installers in the UK. However, the company was dissolved in 2018 due to its parent company (Entu Group)’s financial troubles.

Zenith had a reputation for offering quality service and good quality uPVC windows at and affordable price, but the company was not perfect. Their consistent issues with their sales team meant that you had to be on your guard when getting a quote for your windows.

The good news is there’s no shortage of professional window installers that you can explore.

Keep reading this guide to learn about these companies’ selling and price points based on TrustPilot reviews (as of February 2024) and their history.

Other high-rated providers to consider

What are Good Prices?

Professional window installers can offer many accessories, payment schemes, and warranties, significantly affecting pricing. But what are the reasonable prices to watch out for?

Below is a summary based on the window type.

Type of Window  Average Cost   
Bay (3 panels)£1,190 –  £2,700
Bow (4 panels)£1,430 – £3,240
Casement£160– £1,240
Sash£240 –£1,860
Tilt & Turn£200 – £1,550

These prices will change dramatically depending on the installation, fittings, service, insurance, and other factors. In most cases, the following factors will affect your quote the most.

  • Fittings – This can range from 4-8 styles.
  • Glass – Stained, Georgian, sandblasted, decorative, obscure, resin, ecoA, and more.
  • Frames –  Casement, Sash, Tilt & Turn, Bow, and Bay.
  • Your Home – Your home will greatly affect the installation cost, which means that you cannot get an accurate quote without an inspection. Details like the condition of your walls, the height of your home, your existing windows, and even the existing frame in the windows will affect installation costs.

It’s always a good idea to decide which types of windows and doors you need and why before you schedule a sales appointment. This will allow you to get a better price and will allow you to avoid pressure sales tactics to upgrade to a more expensive window or model.

Getting a Good Deal from Window Installers

These are the best practices to remember to get the best out of your potential service provider. Remember, the upfront costs can be expensive, so you have to choose wisely.

Get Quotes – Request quotes from other companies in advance so that you know what your project is worth and so you can show the lowest offers to the Weatherseal salesperson.

Recommendations From Family/Friends – There’s no better review than from people you trust the most. Ask around your network, take a look at the finished installations, and ask for negotiation tips and payment schemes that worked best for them.

Plan Your Windows – It’s important to know what you want and why before you meet with a surveyor. Taking the time to conduct research to learn what your installation should be worth can also help you to get a good deal.

Be Careful – Don’t sign anything on the same day! Ask for time to review your contract, and make sure you review your offerings and what’s included (yes, even the fine print). In some cases, you may be asked to pay for mandatory insurance (it’s illegal to require insurance) and other fees, so you should take the time to look these up online.

Review the Work – Take the time to review all work completed by the fitters before signing off on it. If you’re unhappy with the installation, accredited companies should have a FENSA-backed guarantee. Plus, the Consumer Rights Act 2015 protects you from faulty goods or services.

If you’re looking for the best deal from a top-rated company, use our free service to find and compare top rated installers in your area. We will search for quotes based on your specifications and forward you the top 3, so you can choose your favorite, or not, there’s no obligation.
