What installers quote for
What can you get quoted for in Brighton?
Brighton and Hove installers quote for replacement windows, sash-style windows, sealed units, repairs and secondary glazing, from one misted pane in Patcham to every sash on a Kemp Town house.
- Replacement windows in uPVC, aluminium or timber, as casements or tilt and turn.
- Sash-style windows in timber, or in uPVC made to sash proportions.
- Sealed units for misted glass in a frame that is still sound.
- Repairs to worn seals, stiff hinges, broken handles and failing locks.
- Secondary glazing behind an original window that has to stay (ask the installer).
Window firms do not all fit doors. Ask each installer whether a front or back door can be added to the same quote.

Article 4 streets
Do you need planning permission for new windows in Brighton?
New windows need planning permission on Brighton and Hove homes covered by a heritage Article 4 direction. Brighton & Hove City Council says these directions "mean that planning permission is required for minor developments", and gives "For example new porches, replacement windows and doors, replacement roof coverings".
Which areas the directions name
The council's list, dated "as of 22 September 2021", names directions for Kemp Town, Brunswick, North Laine, Regency Square, Hanover Crescent, Montpelier Crescent, Preston Park, Round Hill, West Hill, The Avenues and Queen's Park. It also reaches the villages: Rottingdean, Ovingdean, Patcham, Stanmer Village and Portslade Old Village. Hove's Adelaide Crescent, Palmeira Square and Western Road share one direction.
Why flats and houses differ
Householder permitted development rights (GPDO 2015, Schedule 2, Part 1, Class A) cover houses, not flats. An Article 4 direction removes those rights for the works it names, so in these areas a house loses the same freedom that a flat never had.
- Find your street on the council's Article 4 directions page before you book a survey.
- Ask each installer whether they prepare the drawings a planning application needs.
- Read the council's guidance on energy saving in conservation areas and listed buildings, and its PAN 09 householder note (December 2016).

Period homes
Sash and period window quotes for Brighton's pre-1919 homes
Period property makes up a large share of Brighton's window market: 40.0% of Brighton and Hove homes were built before 1919, and 32.6% before 1900, against 20.0% before 1919 across England (VOA, 31 March 2026).
Many of those homes started life with timber sash or casement windows, often set in bays. Many openings now hold an earlier replacement, so frame style and the planning rules above weigh more on a Brighton quote than in most places.
- Ask for a timber sash quote and a uPVC sash-style quote on the same visit.
- Ask whether the installer measures box-sash and bay openings in person.
- Ask for each bay as its own line, with the making good of reveals listed.
For the choice between a timber sash and a uPVC copy, see our page on sash window replacement.

Flats and conversions
Flats and conversions: consent before your Brighton quote
Brighton flats usually need the freeholder's or managing agent's written consent for new windows, and a different look can need planning permission. Half the city lives this way: 50.0% of Brighton and Hove households are in flats, and 21.1% in flats converted from houses or other buildings, against 22.2% and 4.3% across England (Census 2021, TS044).
A converted house often has several leaseholders behind one front elevation. Ask the freeholder whether the building has a set frame colour, material or glazing pattern, so every quote matches it.
- Read the lease for who owns the windows and what consent it requires.
- Get written consent before the survey, not after the quote.
- Ask installers whether they supply the drawings or specifications a freeholder asks for.
Our guide on replacing windows in a leasehold flat covers who pays and who signs.

Rented homes
Window quotes for Brighton landlords
Brighton landlords buy windows against an EPC deadline: 32.7% of Brighton and Hove households rent privately, against 20.5% across England (Census 2021, TS054). A let home needs EPC band E or better today, and the government's target for privately rented homes is band C by 2030, according to GOV.UK landlord guidance updated in May 2026.
Replacing single glazing is one of the measures that moves an EPC.
- Ask for the Window Energy Rating or U-value of every option, so the EPC assessor can record it.
- Ask for a single quote across all your lets, with a total for each address.
- Ask how the installer arranges access with tenants and managing agents.

Repair or replace
Is it worth replacing 20 year old double glazing in Brighton?
Replace 20-year-old double glazing when the frame rots, warps or stops locking; repair it when the fault is a misted unit or a worn fitting. Misting between the panes shows that the sealed unit's seal has failed, and a new unit drops into the existing frame.
- Repair: one misted unit, a stiff hinge, a loose handle or a failing lock.
- Secondary glazing: an original sash on an Article 4 front that is staying.
- Replacement: frames that have rotted, warped or stopped locking.
Ask the same installer for both prices.

Before you choose
How to compare Brighton double glazing installers
Check four things on every Brighton installer before you compare totals: the FENSA or CERTASS register, Companies House, the guarantee and the detail on the quote. The page on double glazing installers shows how to run each one.
- Look for the firm's name on the FENSA or CERTASS register.
- Look up the company's age and filings on Companies House.
- Ask for the guarantee in writing, and whether an insurer backs it.
- Make sure the quote names every window, its energy rating and any planning drawings.
In November 2023 Brighton and Hove's trading standards team warned residents about traders who are not fully qualified or insured (Journal of Trading Standards). Read our contract checklist before you sign anything. If you sign at home, you usually have at least 14 days to cancel, but made-to-measure windows can be an exception, so check the contract before you sign.

FAQ
Brighton double glazing questions
Who contacts me after I ask for quotes in Brighton?
We ring first to confirm the details, and local installers who cover your BN postcode then call to book a survey before sending a written quote.
Do I need planning permission to replace windows in a Brighton conservation area?
You need planning permission for replacement windows where a heritage Article 4 direction covers your home, as in Kemp Town, Brunswick and North Laine, so check the council's Article 4 list before the survey.
Can I replace windows in a leasehold flat in Brighton?
You can replace windows in a Brighton leasehold flat once the freeholder or managing agent gives written consent, and a change of look can need planning permission because flats have no householder permitted development rights.
Is there a grant for double glazing in Brighton and Hove?
Brighton and Hove is on the July 2026 Warm Homes: Local Grant list as part of a Portsmouth-led consortium, and double or triple glazing is an eligible measure for qualifying homes.
Is it worth replacing 20 year old double glazing?
Twenty-year-old double glazing is worth replacing once the frames rot, warp or stop locking, while a misted unit or worn fitting is a repair job.
What are the disadvantages of double glazing?
Double glazing's drawbacks are the upfront outlay, sealed units that mist when their seal fails, and the planning permission that Article 4 streets in Brighton and Hove require for replacement windows.
How much should I expect to pay for double glazing?
The total depends on the number of windows, the frame, the glass and any planning work.
