Brighton's housing stock throws up more variety than most cities its size. You've got Regency terraces around Kemptown and Clifton Hill that need slimline timber sash windows to satisfy conservation rules, Victorian bay-fronted houses in Hanover and Fiveways, and newer builds out towards Woodingdean and Patcham where uPVC or aluminium is more straightforward. Add in the salt air coming off the seafront, which chews through cheap frames and fittings faster than inland areas, and it's easy to see why choosing the right installer matters more here than in a lot of places. Conservation area restrictions around the Lanes and North Laine also mean some jobs need planning permission or listed building consent before any glass gets touched.

The businesses featured here are pulled from public business listings and ranked mainly by review rating and how many reviews they've built up, with a small boost given to those showing a working website and phone number. We check each installer's homepage to confirm window installation is genuinely what they do day to day, which stops general builders or double glazing sales firms with no fitting team from cluttering up the page. Any listing flagged as permanently closed gets removed as part of that same process. Where you spot a Trust Verified badge next to a business, that firm has gone through our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. For businesses without the badge, none of that has been independently checked by us, so it's worth doing your own due diligence before signing anything.

Before booking, ask to see FENSA or CERTASS certification, since this covers Building Regulations compliance for replacement windows and you'll need it for proof when you come to sell. Check whether the quote includes disposal of old frames, scaffolding if you're above ground floor, and making good to plaster or render around the reveals. Get written guarantees on both the glass units and the installation labour, ideally insurance-backed rather than just a company promise. Getting three quotes is standard practice in Brighton, not overkill, because prices for the same spec can vary by a few hundred pounds between firms depending on how busy they are and whether they're subcontracting the fitting.
How We Select & Rate The Best Window Installers in Brighton

Rankings are driven primarily by review rating and review count from public business listings, with a small lift for businesses showing a working website and phone number. We check each business's homepage to confirm window installation is what they primarily do, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information (see our How We Verify page for the complete list). Other businesses here haven't been independently verified by us, and appearing on this page isn't an endorsement, so do your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a window installers cost in Brighton?
A single uPVC window supplied and fitted typically runs from £400 to £700 depending on size and whether it's a straightforward casement or a bay. Timber sash windows, common on Brighton's Regency and Victorian streets, cost more, often £800 to £1,500 per window once you factor in the joinery and matching original proportions. A full house re-glaze on a three-bed terrace can land anywhere between £5,000 and £12,000. Prices shift with glazing spec (double vs triple), frame material, and access, so getting two or three written quotes before deciding is worth the extra week it takes.
Do I need planning permission for new windows in Brighton?
Most window replacements fall under permitted development, but if your property sits in a conservation area, such as parts of the Lanes, Clifton Hill or Cliftonville, or is listed, you'll likely need consent before changing frame material or window style. Brighton & Hove City Council's planning portal has a postcode checker. Always confirm this with the council directly rather than relying on the installer's word alone, since the liability for unauthorised work sits with the homeowner.
How long does a typical window installation take?
A straightforward single window swap usually takes half a day to a day. A full house of eight to ten windows generally takes two to four days, longer if there's render repair, lintel work, or scaffolding involved for upper floors. Sash window restoration or replacement tends to take longer per window than uPVC casements because of the joinery involved, so factor that into your timeline if you're doing this ahead of a house sale or before winter sets in.
What's better for a Brighton home, uPVC, timber or aluminium windows?
It depends on the property and the street. UPVC suits newer builds in areas like Woodingdean or Saltdean and needs little maintenance, which matters given the salty coastal air. Timber sash windows are usually required or preferred on period properties in Kemptown, Hanover or the conservation areas, and modern engineered timber holds up better than old softwood against damp. Aluminium works well for larger glazed extensions or contemporary renovations but costs more upfront. An installer who's worked across Brighton's mixed housing stock should be able to talk through the trade-offs rather than pushing one option.
Will new windows help with condensation and draughts in an older Brighton flat?
Often yes, especially in Victorian conversions where original single-glazed sashes have gaps that let cold air straight in. Modern double glazing with proper draught seals cuts condensation significantly, though if the flat has poor ventilation generally, you might still get some moisture build-up around the frames until trickle vents or an extractor are added. Ask your installer whether the units come with argon-filled cavities and low-E glass, since this makes a noticeable difference to both draughts and heating bills.
How do I choose between window installers in Brighton?
Start by asking to see their FENSA or CERTASS registration number and check it independently on the relevant scheme's website, since anyone can claim to be registered. Ask for photos or addresses of recent local jobs, ideally similar property types to yours, and try to see the work in person if possible. Confirm what guarantee covers the glass units versus the installation itself, and check whether that guarantee is insurance-backed, meaning it survives if the company closes down. Read through recent customer reviews yourself rather than relying on a star rating alone, and get at least two other quotes so you've got something to compare on price and scope.
