Double glazing in Hampshire: compare free local quotes
Compare free written quotes from local installers who cover your Hampshire postcode, for new windows, glass-only replacement, repairs and acoustic or secondary glazing. Hampshire has far more detached houses than England as a whole, and most homes are post-war, so a whole-house quote covers more windows and the gaps between quotes grow.

What changes a Hampshire double glazing quote
Seven things change a Hampshire quote: house size, the age of the windows, listing, Article 4 directions, airport noise, the coast and the grant list. Check which apply to your address before the survey.

Consent
Who gives consent for new windows in Hampshire and the New Forest?
Your district council or national park authority decides window consent in Hampshire, not the county council. Planning runs through 11 districts, plus the New Forest and South Downs national park authorities for homes inside the parks.
- Listed homes: 10,857 listed building entries, about 17.0 per 1,000 homes against 14.6 for England. Almost any window change needs listed building consent, and timber like-for-like is often expected; original sashes belong in a quote for sash window replacement or repair.
- Conservation areas: Basingstoke and Deane has more than 40, the most of any Hampshire district by its own count. Planning data lists 16 for the New Forest National Park Authority.
- Article 4 directions: 3 of the 213 Article 4 areas published for the county remove the householder rights that cover windows or mention windows. Basingstoke publishes Article 4 advice for its conservation areas.
Outside those three cases, replacement windows on a house usually need no planning permission when they look similar to the originals. Check your address with the district or park authority, then ask installers which consent applications they have handled there.

Aircraft noise
Acoustic glazing quotes near Southampton Airport
Southampton Airport sits in Eastleigh borough and runs a Noise Insulation Scheme for eligible homes near its flight paths. Check whether your street falls inside the scheme's contour on the airport's site before paying for new windows in full.
If you live outside the contour but under the approach, ask installers for acoustic glazing: laminated glass, panes of unequal thickness or a wider cavity. Each quote should state the sound reduction (Rw) figure, so the acoustic options compare on performance as well as price.

Coast
Window quotes for Hampshire's Solent and seafront homes
Hampshire faces open sea and the Solent, and exposed coastal plots put more wind and salt on frames, hinges and handles than inland streets. Ask each installer for the window's weathertightness classification under BS 6375-1, which tests air, water and wind resistance. Also ask whether the hinges, handles and frame finish are rated for coastal use. Fareham's waterside homes in Warsash, Swanwick Shore and Portchester are covered on our page for double glazing quotes in Fareham.

Repair or replace?
Repair or replace: what most Hampshire quotes are for
Most Hampshire quotes replace post-war windows, and many need only new glass: 43.4% of homes in the county council area date from 1945 to 1982 and only 10.3% predate 1919, against 20.6% across England and Wales. These figures exclude Southampton and Portsmouth, which are separate councils.
Homes of that age have standard openings, and many already carry their first or second set of double glazing. Ask each installer to price these as separate options:
- repairs to hinges, handles, locks and seals;
- sealed-unit (glass only) replacement where frames are sound and only the glass has misted;
- full-frame replacement, priced per window.
More windows per detached house means a bigger difference in pounds between the highest and lowest quote, so compare three quotes line by line, as set out in our guide on how to compare double glazing quotes.

Before you sign
How to pick a double glazing installer in Hampshire
Pick a Hampshire installer by checking seven things yourself, in this order, before any survey visit:
- Scheme register: find the firm on the FENSA or CERTASS register by name or postcode. Both are government-authorised, and a registered installer certifies the job under Building Regulations.
- Company record: search Companies House for the name on the quote. Check it is active and how long it has traded, since Which? suggests 10 years or more, and look for earlier names.
- Guarantee: get it in writing and ask whether it is insurance-backed. FENSA does not issue guarantees, and Which? recommends a ten-year insurance-backed guarantee.
- Fitters: ask whether the firm's own staff fit the windows or subcontractors do, and who handles snags.
- Survey: expect every opening measured before a final price, from a surveyor who will not pressure you.
- Itemised quote: each window priced on the same specification, so three quotes compare line by line.
- No doorstep deals: Hampshire County Council Trading Standards warns residents about rogue traders and doorstep callers, so never agree to work on the doorstep or accept a "sign today" price.
Take our list of questions to ask a double glazing salesman to the survey, and see our page on double glazing installers for the paperwork.
All 11 Hampshire districts are on the July 2026 Warm Homes: Local Grant list, and glazing is an eligible measure, so ask your district council about eligibility before you plan a grant-funded job.

FAQ
Double glazing in Hampshire, answered
Is there a government grant for double glazed windows?
All 11 Hampshire districts are on the July 2026 Warm Homes: Local Grant list, and glazing is an eligible measure. Homes near Southampton Airport can also check its Noise Insulation Scheme.
Do I need planning permission for new windows in the New Forest?
Usually not, when the new windows on a house look similar to the old ones. Listed homes need listed building consent, and conservation areas or Article 4 directions can remove the usual right. Inside the national park, the New Forest National Park Authority decides planning, not the district council.
Is Southampton covered by the Hampshire page?
No. Southampton and Portsmouth are separate unitary councils with their own planning and data. Southampton has its own page, linked in the areas section above.
Is it worth replacing 20 year old double glazing?
Replacing 20-year-old double glazing is worth it when the frames are warped, damaged or will not lock; misted units in sound frames need only new sealed units. Many Hampshire homes are on their second set of double glazing, so ask for glass-only and full-frame prices on the same quote.
What is the best time of year to buy double glazing?
Get quotes well before you need the windows fitted, so there is time to compare them and sort any consent. Our guide to the best time to buy double glazing covers lead times and fitting weather.
What are the disadvantages of double glazing?
The main disadvantages of double glazing are the upfront cost, sealed units that mist when their seal fails, and less period character where modern frames replace originals. Well-sealed frames let less air through, so check each quote includes ventilation such as trickle vents. Hampshire's 10,857 listed entries need listed building consent for almost any window change, so repair or secondary glazing can be the simpler route there.
How much should I expect to pay for double glazing?
The price depends on the number of windows, the frame material and the glass, so compare itemised quotes, and see what double glazing costs in each UK region on our sister site.
What is the average cost of double glazing windows in the UK?
The average cost of double glazing has no single answer, because window count, frame material, glass and consent work change every quote; the regional link in the answer above gives the figures.
