Double Glazing Birmingham: Costs, Grants and Companies 2026

A full 3-bed semi in white uPVC costs about £3,750 on MyJobQuote’s national figures. We found no verified Birmingham-specific price, so get local quotes to see how they compare.

Individual uPVC casement windows cost £350–£550 each supplied and fitted on MyJobQuote’s national figures. Aluminium casements cost more at £600–£850 per window, while timber casements range from £750–£1,100. Quotes should include VAT at the standard 20% rate; double glazing is standard-rated and does not qualify for the 0% energy-saving-materials relief (GOV.UK Notice 708/6).

In this guide, we cover Birmingham-specific double glazing costs, available grants (including the Warm Homes: Local Grant, which covers six priority areas in Birmingham), conservation area rules – including the Jewellery Quarter and Bournville – and tips for getting the best price.

Double Glazing Costs in Birmingham

On MyJobQuote’s national figures, double glazing a 3-bed semi costs about £3,750 in white uPVC, £4,700–£5,600 in aluminium and £7,500–£12,000 in softwood timber. We found no verified Birmingham-specific prices. For a full UK breakdown, see our double glazing costs guide.

Costs depend on window style, frame material, and the number of windows being replaced.

National figures cover supply and fitting; confirm that quotes include disposal of old windows and FENSA certification. MyJobQuote counts roughly 6-8 windows for a 2-bed terrace and 8-10 for a 3-bed semi. For a 4-bed detached home, MyJobQuote’s national figure for white uPVC is £5,500–£7,000.

Choosing Windows for Your Property

Window style and material depend on the age and character of your home, including the Arts and Crafts homes of Bournville.

Victorian terraces with original single-glazed sash windows have the most to gain from upgrading – but window style and material matter more here than in suburban semis, where standard uPVC casement is usually appropriate.

For period properties, uPVC sash windows (£700–£1,100 each on MyJobQuote’s national figures) replicate the look of traditional timber sashes at a fraction of the maintenance cost. In conservation areas – particularly the Jewellery Quarter – timber or slim-profile aluminium frames may be required or strongly preferred.

Double Glazing Grants in Birmingham

The main scheme for Birmingham residents is the Warm Homes: Local Grant, which provides up to £16,600 per home for energy efficiency measures, but Birmingham delivery is place-based and the council’s funded measures do not list double glazing. Nationally, you need a household income of £36,000 or below and an EPC rating of D–G. Note that double glazing itself does not qualify for the 0% energy-saving-materials VAT relief – it is standard-rated at 20% (GOV.UK Notice 708/6). For all UK schemes, see our double glazing grants guide.

Warm Homes: Local Grant

The Warm Homes: Local Grant is Birmingham’s main home-energy grant, but it is unlikely to pay for new windows. Launched in April 2025 with £500 million of government funding, it provides up to £16,600 for energy efficiency improvements – and double glazing is on the national eligible-measures list, though councils recommend it only in rare cases. Birmingham’s delivery is place-based: it covers six priority areas (Balsall Heath, Bromford, Castle Vale, Sparkbrook, Sparkhill, and Tyseley and Hay Mills), and the council’s list of funded measures does not include windows.

To qualify, you need a household income of £36,000 or below (or be receiving a means-tested benefit), have an EPC rating of D, E, F, or G, and be a private homeowner or private renter in England. Owner-occupiers are not expected to contribute, though landlords may have to pay towards the work. Apply at gov.uk/apply-warm-homes-local-grant – the postcode checker confirms whether your area is covered.

VAT on Double Glazing (Standard-Rated 20%)

Double glazing is standard-rated at 20% VAT. It does not qualify for the 0% energy-saving-materials relief – GOV.UK VAT Notice 708/6 (section 2.23) lists secondary and double glazing as standard-rated. The 0% rate covers insulation, solar panels and heat pumps, not windows or glazing, so expect 20% VAT on any quote.

Conservation Areas in Birmingham

Birmingham has 29 conservation areas where window replacements may face additional restrictions. The Jewellery Quarter is a conservation area but is not on the council’s list of Article 4 Direction areas; Bournville Village, Moseley and part of Edgbaston are. Bournville has separate Bournville Village Trust covenants on top of standard rules. Like-for-like replacements are usually permitted development elsewhere.

Replacement windows are normally permitted development in England – you don’t need planning permission provided the new windows match the existing ones in appearance. However, Birmingham’s conservation areas add complexity that’s important to understand before you order.

Key Birmingham conservation areas where double glazing requires extra attention:

• Jewellery Quarter – One of England’s largest conservation areas. It is not on the council’s Article 4 list, so conservation area rules apply rather than an Article 4 Direction. Conservation officers may prefer timber or slim aluminium over uPVC for street-facing windows.
• Bournville – Cadbury’s model village is covered by an Article 4 Direction, so replacing windows needs planning permission, and separate Bournville Village Trust covenants may be more restrictive. Contact BVT directly at bvt.org.uk before ordering windows for any Bournville property.
• Edgbaston – Victorian and Edwardian residential, with an Article 4 Direction covering part of the area. Original bay windows and sash window proportions are character-defining features. Replacements should closely match originals. uPVC acceptable if accurately replicating the original style.
• Moseley and Harborne – Article 4 Directions cover Moseley, Moor Pool Harborne and Greenfield Road, so replacing windows there needs planning permission; check your exact boundary with the council. Elsewhere in Harborne, like-for-like replacements are usually fine.
• Kings Norton – Medieval village core. Stricter rules apply to listed properties near the village centre.

Outside the Article 4 areas, like-for-like uPVC replacements are permitted development provided the new windows match the existing design. Where in doubt, contact Birmingham City Council’s planning team via birmingham.gov.uk (search ‘conservation areas’) for advice before you order.

Choosing a Double Glazing Company in Birmingham

Before choosing an installer, confirm they are FENSA or CERTASS registered at fensa.org.uk – without certification you’ll need separate Building Control sign-off, which adds cost and delay and can complicate future property sales. Check recent reviews on more than one site, and for a national comparison see our best window companies guide.

How to Get the Best Price in Birmingham

Get at least three quotes, ask whether quieter months bring better terms, and ask about whole-house discounts.

To get the best outcome:

• Get three quotes minimum – prices can vary widely between installers for identical work. Never accept the first quote.
• Time your purchase – ask whether installers offer shorter lead times or better terms outside the summer peak.
• Ask about whole-house discounts – replacing all windows at once is cheaper per window than doing them in stages. Ask each installer what discount they offer for a full-house job.
• Check FENSA registration – verify any installer at fensa.org.uk/find-installers. Non-registered installers may quote lower, but you’ll pay separately for Building Control inspection and may face problems when selling.
• Consider energy ratings – A-rated energy-efficient windows cost slightly more but deliver better thermal performance. The minimum for replacement windows is band B. For Birmingham’s urban noise levels, acoustic glass is worth asking about.

What to Expect on Installation Day

Fitting typically takes 1 day for 3-5 windows and 2-3 days for a full house of 8-12 windows. Installers will protect your floors and furniture, remove old frames cleanly, and fit new windows with expanding foam and silicone sealant around the frame perimeter. Plan to be home while the work is done.

After installation, your installer should provide:

• FENSA or CERTASS certificate – keep this safe, you’ll need it when selling your property
• A manufacturer’s guarantee for the frames and glass units (check the length and what it covers)
• Confirmation that the work complies with Part L (thermal performance) of the Building Regulations

A few days after installation, check all windows open, close, and lock smoothly and that frame sealant is neat and continuous. If any units show signs of condensation between the panes (indicating failed sealed units), notify your installer immediately – this is a manufacturing defect and should be covered under the product guarantee at no charge to you.
