    What folks say about us

    Astonishingly good or room for improvement, it’s all here. Thank you to all our customers old and new. We really appreciate your reviews. Really. Yes, really, really.

    When you make improvements you want them to last

    We aim to offer products that do more than look great and last well—they transform houses in three dimensions: style, performance, and security.

    Style is down to you to choose, but be sure to take a good look at the elements of style, especially those we include in all our installations as standard, like deep window cills and overhead ventilation.

    Performance matters in ensuring rooms are comfortable and energy efficient. We’ve worked hard to find products that meet the highest standards across our range. All our windows and doors, for example, are fitted with Eco-Max glass—they add sustainability credentials to manufacturing quality.

    Security is more than skin deep. The outward materials of a door, for example, partly define its ability to resist attempts at a break-in, but so too do its locks, operating mechanism and the construction of the frame and in-fill. As with performance, it pays to ask questions when comparing different products, and be prepared to insist on high standards.

    Help & FAQs – New windows & Doors

    We keep it simple: transparent quotes, tidy installs, and accredited fitters. These FAQs cover the basics: cost, timing, energy performance and guarantees. So you can make a confident choice.

    How much can I save during the SEH BAC promotion?

    There's never been a better time to improve your home. Eligible customers can save up to 30% on selected windows, doors and conservatories, with a free upgrade to triple glazing available for a limited time. Qualifying orders may also receive a free home security system, alongside other promotional benefits. Offers are subject to product selection, specification and minimum order values.

    Which products are included in the promotion?

    How do I know if my windows need replacing?

    There are always obvious signs like poor fit, rot in wood, loose fittings, and inconsistent lock operation, but sometimes it’s just time for a change. New windows can have a big impact on the outward appearance of your home.

    How much will new windows cost?

    Thermally sound, industry-accredited custom-made windows must be individually priced to take into account manufacturing to size and any features you wish to specify. We offer a range of finance options to spread the cost of new windows. You can read more about what affects the price of double glazed windows on our site.

    Which windows material is best?

    The best material depends on your priorities. PVCu windows offer excellent value, energy efficiency and low maintenance, while aluminium windows provide slimmer frames and a contemporary appearance. Both are secure, durable and fitted with highly accredited hardware. Explore our award-winning range and read more about PVCu vs aluminium windows.

    Do you offer finance?

    Yes. Subject to status, qualifying customers can spread the cost with a range of finance options, including interest-free credit on qualifying orders, helping you improve your home without a large upfront payment. Please see our finance page for all options and details.

    Will new windows and doors add value to my home?

    High-quality replacement windows and doors can improve kerb appeal, security, energy efficiency and overall property value.

    Which areas do you cover?

    SEHBAC provides expert installation of windows, doors, conservatories, roofline products and home extensions across Suffolk, Essex, Hertfordshire, Surrey, Kent, Norfolk, Cambridgeshire, Bedfordshire and Greater London. With multiple showcentres throughout the region and over 60 years of experience, we regularly work with homeowners in locations including Ipswich, Colchester, Chelmsford, Maldon, Hertford, Norwich, Bury St Edmunds, Cambridge, Enfield and surrounding areas.

    If you're unsure whether we cover your area, our team will be happy to advise and arrange a free no-obligation quotation at a time that suits you.

    Can I visit a showroom before I buy?

    Absolutely. Visiting a SEH BAC showroom allows you to compare products, colours, glazing options and hardware before making your decision. Just book your FREE no obligation appointment with one of our designers at your nearest showroom here.

    How long does installation take?

    Timescales vary depending on the size and complexity of the project, as well as the products selected. Before work begins, your surveyor and installation team will provide a clear schedule and keep you informed of any key dates.

    Do your products come with a guarantee?

    Yes. SEH BAC products are supplied with comprehensive guarantees for added peace of mind. All window, door, conservatory, extension, garage door, roofline and cladding products include a 10-year guarantee.

    Do I need planning permission?

    Most replacement windows and doors do not require planning permission and can be installed under permitted development rights. However, requirements can vary depending on your property, particularly if you live in a conservation area, a listed building, or are planning a larger home improvement project such as an extension or new conservatory.

    If planning permission is required, SEH BAC's dedicated Planning Team can manage the entire process on your behalf. This includes preparing the necessary drawings, submitting the application, liaising with the local authority and managing the application through to a decision. In most cases, there is no need to appoint a separate architect, helping to make the process simpler and more convenient for homeowners. Our team will advise you on any planning requirements and guide you every step of the way.

    Why Choose SEH BAC Over National Companies?

    SEH BAC combines the buying power and guarantees of a large installer with the personal service of a local family-run business. With more than 60 years of experience, dedicated showrooms and fully project-managed installations, we provide a tailored service from quotation through to completion.
