Double glazing across Berkshire, made and fitted by one team
Some window companies buy in frames made elsewhere and use subcontractors to fit them. We work differently. Your aluminium windows and doors are fabricated in our Fifield workshop, in the Royal Borough of Windsor and Maidenhead, and fitted by the same team that surveyed your home. That keeps one point of contact from the first visit to the final check, and it means any snag is ours to fix.
We are a listed Reynaers at Home installer partner and hold Constructionline Silver. Alongside aluminium we install UPVC windows and doors on the Selecta Advance 70 system, composite doors, conservatories, orangeries, porches, roof lanterns, secondary glazing, garage doors, fascias, soffits and guttering, and blinds and shutters.
Berkshire’s six councils and who handles planning
Berkshire is a ceremonial county. Berkshire County Council was abolished in 1998 and replaced by six unitary authorities, and each one is the local planning authority for its own area. If your project needs planning permission, listed building consent or a check against an Article 4 direction, it is your own council you deal with:
- Royal Borough of Windsor and Maidenhead: Windsor, Maidenhead, Ascot, Sunningdale, Cookham, Bray, Datchet, Wraysbury and Old Windsor. See our Windsor, Maidenhead and Ascot pages.
- Slough Borough Council: Slough, Langley, Cippenham and Colnbrook. See windows and doors in Slough.
- Bracknell Forest Council: Bracknell, Crowthorne and Sandhurst. See Bracknell, Crowthorne and Sandhurst.
- Wokingham Borough Council: Wokingham, Earley, Woodley, Twyford and Wargrave. See Wokingham and Earley.
- Reading Borough Council: the town of Reading. See windows and doors in Reading.
- West Berkshire Council: Newbury, Thatcham, Hungerford and Lambourn. See Newbury and Thatcham.
For most houses, like-for-like replacement windows do not need planning permission. The Planning Portal says permission is usually not needed for new windows and doors “of a similar appearance” to the originals. A new bay window counts as an extension, listed buildings need listed building consent for significant works, and an Article 4 direction can remove the usual rights. Leaseholders may also need consent from the freeholder or management company. Our guide to planning permission for replacement windows covers this in more depth.
Typical Berkshire homes and what suits them
Berkshire’s housing changes a great deal from one end of the county to the other, and the right window depends on the house as much as the budget.
Victorian and Edwardian terraces and villas
Reading has a large stock of period brick housing. Reading Borough Council’s appraisal of the Redlands Conservation Area describes it as an “essentially Victorian/Edwardian suburb” with polychromatic brickwork and original glazing-bar sash windows. Similar period streets run through Windsor, Maidenhead and Newbury. For homes like these we usually suggest UPVC sash windows, slim aluminium casements, or secondary glazing where the originals have to stay.
Post-war new town and estate housing
Bracknell was designated a new town on 17 June 1949 under the New Towns Act 1946, and much of east Berkshire grew rapidly after the war. Plain casement openings on post-war semis and terraces suit cost-effective UPVC windows and doors on the Selecta Advance 70 system, or aluminium if you want slimmer frames and a more modern look.
Larger detached and contemporary homes
Around Ascot, Sunningdale, Wokingham and the Thames villages, many homes are detached, extended or newly built. These are where wide glass and slim frames make the most difference: Reynaers ConceptPatio 130 sliding doors, Smart Visofold and Cortizo bifold doors, and aluminium windows across the rear elevation.
Local factors that change the specification
Conservation areas and Article 4 directions
Berkshire has a lot of protected townscape. The Royal Borough of Windsor and Maidenhead lists 27 conservation areas, including Inner Windsor, Eton, Datchet, Bray Village, Cookham Village and Maidenhead Town Centre. West Berkshire has 53, among them Newbury Town Centre, Hungerford, Lambourn and Thatcham, and Wokingham Borough lists 16, such as Sonning, Wargrave and Wokingham town centre.
Article 4 directions vary street by street. Reading Borough Council has directions on streets with patterned brickwork, including Field Road and Jesse Terrace, that remove all permitted development rights. RBWM’s Bray Conservation Area direction requires approval for most minor development to the front elevations of defined properties. Check your address with your council before ordering; we can help you prepare drawings and specifications if an application is needed.
Thames flood risk
The Thames shapes much of east Berkshire. The Environment Agency’s Jubilee River reduces flood risk to over 3,000 properties in Maidenhead, Windsor, Eton and Cookham, but villages downstream are not covered by it. During Storm Henk, water flooded parts of Wraysbury, Datchet, Horton and Old Windsor. You can check your area on the government’s long-term flood risk service. In flood-prone homes we pay close attention to threshold heights, drainage and sealing on doors, and our aluminium and UPVC frames avoid the rot that can affect timber.
Heathrow aircraft noise
East Berkshire sits close to Heathrow. Heathrow’s Quieter Neighbourhood Support package includes a Residential Insulation Scheme offering up to 100% funding of eligible insulation costs where they are recommended by a free independent survey. According to Heathrow’s own FAQs, homes are eligible if they lie within a single composite boundary based on UK noise policy, phase one runs from 2025 to 2028, and the scheme aims to reach around 20,000 of the most affected homes. Measures can include replacement windows or secondary glazing, external doors, acoustic ventilation, loft insulation and ceiling upgrades; specification upgrades beyond the agreed works and planning costs are not covered. Check your postcode with Heathrow first. If you are outside the boundary, our sound-reducing windows with acoustic laminated glass are the next best step.
The North Wessex Downs National Landscape
In the west of the county, West Berkshire Council says the North Wessex Downs National Landscape covers three-quarters of the district. Many cottages and farmhouses around Lambourn and Hungerford sit within it, often in conservation areas too. Window style, colour and glazing bar detail matter more here, so we discuss options with you before quoting.
Which products suit which Berkshire homes
| Home | Our usual recommendation |
|---|---|
| Period terrace or villa | UPVC sash windows, Reynaers SlimLine 68 outward-opening casements, or secondary glazing |
| Post-war semi or terrace | Selecta Advance 70 UPVC windows, or Cortizo and Alunet aluminium windows |
| Modern detached or extended home | Aluminium windows, Reynaers ConceptPatio 130 sliding doors, or Smart Visofold and Cortizo bifolds |
| Home near Heathrow or a busy road | Acoustic laminated double glazing or secondary glazing |
| Home wanting a timber look | Woodgrain-finish UPVC or aluminium, or a composite front door |
We do not make timber windows or doors, but woodgrain finishes and composite doors give a traditional look with far less maintenance. Our Reynaers SlimLine 68 guide explains that system in detail, and our energy-rated windows page covers thermal performance. If you are considering triple glazing, ask us whether it is available in your chosen system and sizes.

Frequently asked questions
Do I need planning permission for double glazing in Berkshire?
Usually not. The Planning Portal says replacement windows and doors of a similar appearance to the originals rarely need permission. You will need consent for a listed building, and you may need permission if your council has made an Article 4 direction, if you add a bay window, or if you live in a flat. Check with your own Berkshire council before ordering.
Which Berkshire council handles my planning application?
Berkshire has six unitary councils, and each handles planning for its own area: the Royal Borough of Windsor and Maidenhead, Slough Borough Council, Bracknell Forest Council, Wokingham Borough Council, Reading Borough Council and West Berkshire Council. Berkshire County Council was abolished in 1998, so there is no county-level planning department to apply to.
How much do aluminium windows cost in Berkshire?
Our aluminium windows start from £400 each. Published 2026 market guides put aluminium windows at roughly £600 to £1,500 per window installed, depending on size, style and source. Those figures are national guides, not our prices. The best way to get an accurate figure is a free survey, after which we send an itemised written quote.
Can Heathrow pay for new windows at my home?
Possibly. Heathrow's Residential Insulation Scheme offers up to 100% funding of eligible insulation costs where a free independent survey recommends them, for homes inside its eligibility boundary. Phase one runs from 2025 to 2028. Check your postcode with Heathrow first. If you are not eligible, we can fit acoustic laminated glass or secondary glazing to reduce aircraft noise.
How long does it take to get new windows fitted?
Lead times start from 10 days after you approve your quote and we confirm the final measurements. We make aluminium frames in our own Fifield workshop, so there is no wait for a third-party factory. We confirm your fitting date with you, and the time on site depends on the number of windows and doors and any making good needed.
Do you fit timber windows?
No, we do not make or fit timber windows or doors. If you want a timber look, we offer woodgrain-finish UPVC and aluminium windows, and composite front doors with woodgrain textures. These need far less maintenance than painted timber, and in conservation areas we can discuss which style and colour options are likely to suit the street.
