B&Q Now Fits Windows and Doors: What Should Homeowners Compare?

B&Q has recently introduced a fitted windows and doors service, giving homeowners another familiar name to consider when replacing their double glazing. But what should you look at beyond the headline price and product guarantee?

Greater choice can be a good thing, but choosing new windows is very different from buying materials for a weekend DIY project. The products are expected to remain in your home for decades, while the quality of the survey, installation and aftercare can be just as important as the windows themselves.

Before choosing between a national retailer and an established window specialist, there are several important details worth comparing.

Window fitting services compared

Look beyond the product guarantee

B&Q currently advertises a ten-year product guarantee on its fitted windows and doors, along with five years of cover for locking mechanisms.

However, its published installation guarantee lasts for just one year.

This is an important distinction. A product guarantee generally relates to the window or door itself, while installation cover relates to the work carried out when fitting it into your property.

Even a well-manufactured window relies on a correct survey and professional installation. Alignment, sealing, finishing, ventilation and the condition of the surrounding opening can all affect how the finished installation performs.

EYG provides a ten-year warranty on windows and doors installed by our teams, giving customers longer-term reassurance over their home improvement.

Before signing an agreement, ask:

• How long is the product covered?
• How long is the installation workmanship covered?
• Which components have separate guarantee periods?
• Who should you contact if a problem develops?

Who will actually fit your windows?

Although the service is sold through B&Q, the company has partnered with Evander to survey and install its windows and doors.

Using an installation partner is not automatically a problem. However, homeowners should understand which company is responsible for each stage of the project.

You may initially speak to the retailer, have your property surveyed by another business and then have the installation completed by a fitting team working through that partner.

Establish who is responsible for:

• The initial advice and quotation
• The technical survey
• The installation work
• Any damage or fitting problems
• Long-term aftercare
• The installation guarantee

EYG's installations are completed by our own fitting teams. Our installers are qualified to NVQ Level 3 in window installation, and some have worked with EYG for more than 20 years.

Keeping the survey, installation and aftercare within one established company provides customers with a clearer point of responsibility throughout the project.

A new service or an established window specialist?

B&Q is one of the country's best-known home improvement retailers, but its dedicated fitted windows and doors service is new.

That is different from choosing a business with decades of direct experience surveying, manufacturing and installing windows.

EYG was established in Hull in 1971 and has been fitting windows and doors in homes across Yorkshire, Lincolnshire and Nottinghamshire ever since.

This experience can be particularly valuable when a property has:

• Unusual window openings
• Existing bay or bow windows
• Older brickwork
• Structural alterations
• Heritage-style requirements
• Access restrictions
• Several different window or door styles
• Associated plastering or building work

Replacing windows is rarely a completely standard process. Experienced surveyors and installers are better placed to identify potential complications before work begins.

Online convenience versus in-person advice

B&Q begins its process with an online design appointment through Microsoft Teams. Customers provide approximate measurements and photographs before receiving a pre-survey estimate.

This may be convenient for customers who want an initial discussion from home, but photographs and approximate measurements cannot reveal everything about a property.

The construction of the existing opening, condition of the surrounding brickwork, internal finishes, access and ventilation requirements may all influence the final specification.

A technical survey takes place later, but customers should remember that an initial online estimate may change once the property has been properly inspected.

EYG offers appointments in the customer's home, as well as access to regional showrooms where products, colours, handles, glass and frame options can be viewed in person.

For a major purchase, seeing and operating a physical product can be much more useful than selecting it from photographs alone.

Check whether a survey fee applies

B&Q describes its survey as free during the main explanation of its service. However, the terms published on the same page state that a survey fee may apply, which is refundable if an order is placed.

Customers should therefore confirm whether they will need to pay anything before the technical survey takes place.

Before arranging a survey, ask:

• Is the survey completely free?
• Is a payment required before the survey?
• Is any fee only refunded after placing an order?
• What happens if the final price changes after the survey?
• Can you cancel without losing the survey fee?

Compare the full product range

B&Q's published fitted range currently includes PVC windows and doors, patio and sliding doors, aluminium bifold doors and composite front doors.

That will cover many straightforward replacement projects, but customers looking for something more specialist should check whether the required product is included.

EYG provides a wider range of home improvement options, including:

• uPVC windows
• Aluminium windows
• Casement windows
• Tilt-and-turn windows
• Sliding sash windows
• Bay and bow windows
• Composite doors
• uPVC doors
• Aluminium doors
• French doors
• Patio doors
• Bifold doors
• Conservatories
• Orangeries
• Garden rooms
• Replacement conservatory roofs

We can also coordinate associated building and finishing work where it forms part of a larger home improvement project.

The best choice is not simply the company with the biggest name. It is the company that can provide the right product and manage the entire installation properly.

Consider what happens after installation

New windows should provide reliable performance for many years. This makes aftercare especially important.

A company may complete the installation successfully, but homeowners should also consider how easy it will be to obtain support several years later.

Ask where the installer is based, whether it has a local showroom or office and whether it has an established history in your area.

EYG has regional branches covering Yorkshire, Lincolnshire and Nottinghamshire, with its head office and manufacturing base in Hull.

Our customers know who completed their installation, where we are based and how to contact us if they need assistance in the future.

Read independent reviews carefully

Independent review platforms can provide useful insight into how a business communicates, resolves problems and supports its customers.

However, this comparison needs context. B&Q's profile covers its entire retail operation, including shops, online orders, deliveries and thousands of unrelated products. It is not a rating specifically for its new window-fitting service.

Customers should therefore look beyond the overall score and search for reviews that relate to the particular service they are considering.

Ratings also change over time, so always check the latest reviews before making a decision.

Useful things to look for include:

• How installation problems were resolved
• Whether appointments were kept
• The quality of communication
• How cleanly the work was completed
• Whether the final price matched the quotation
• How the company responded when something went wrong

No company will receive perfect feedback from every customer. The way it responds to problems is often more revealing than the score alone.

Seven questions to ask any window installer

1. Who will carry out the installation?
2. How long is the installation workmanship guaranteed?
3. Is the survey free, and are there any upfront fees?
4. Who handles problems after the work has been completed?
5. Are the installers directly employed or supplied by another company?
6. Can I see examples of similar installations?
7. Does the company have an established local presence?

Clear answers will make it easier to compare quotations on more than price alone.

Choose the installer, not just the window

B&Q's new service gives homeowners another option and includes several reassuring features, such as energy-rated products, recognised locking systems and a ten-year product guarantee.

However, the product specification is only one part of a successful window replacement.

Customers should pay equally close attention to the length of the installation warranty, who carries out the work, the experience of the surveyors and installers, and the support available after the project is complete.

B&Q currently provides one year of installation cover. EYG provides a ten-year warranty on windows and doors installed by our teams and has been improving homes since 1971.

When you are making an investment intended to last for decades, choosing an experienced installer with clear accountability and long-term aftercare can make all the difference.

Service details, published guarantee periods and review scores were checked in August 2026. Terms, ratings and product ranges may change. Customers should check the latest information before making a purchase.
