Our Double Glazing Service in Bletchley
Bletchley’s housing runs from pre-war terraces in Old Bletchley through to the post-war overspill estates built between the 1950s and 1970s, including the Saints, Rivers, Castles, and Lakes Estate. Window and door needs vary quite a bit from one street to the next.

Conservatories in Bletchley
Most of Bletchley’s 1960s and 1970s semis were double glazed in the 1990s. That glazing is now 25 to 30 years old, and on estates like the Saints and Rivers, failed seals and draughty frames are common.
Casement windows are the standard replacement, A+13 rated and priced with VAT and fitting included. Older properties in Old Bletchley often suit sliding sash or flush sash windows instead.
Burglary rates in central and east Bletchley run above the Milton Keynes average, so it’s worth making sure your doors are doing their job properly. Composite and uPVC front doors from Apex include multi-point locking and toughened safety glass as standard.
On the Radburn-layout Lakes Estate, where rear pedestrian access is more open, patio and French doors with the same locking spec are worth considering. All prices include VAT and fitting; get a price via the instant online calculator.
The post-war semis across Far Bletchley and West Bletchley typically have enough rear garden for a conservatory under permitted development. Victorian conservatories suit the bay-fronted semis on the Castles and Fairways estates; the cleaner roofline of an Edwardian conservatory tends to fit the rectangular footprints of the 1960s terrace stock better.
Apex handles design, planning queries, and the full build with directly employed fitters and a 10-year insurance-backed guarantee. Speak to our team to discuss what suits your plot.
What Our Customers Say
Frequently Asked Questions
My windows were fitted in the 1990s. Is it worth replacing them or just repairing the sealed units?
It depends on the frames. If they’re still solid with no warping, cracking, or draughts around the edges, replacing just the sealed units is a cost-effective fix. If the frames themselves are letting heat out or the handles and locks are worn, a full replacement makes more sense at that age. Apex carries out both, so it’s worth getting a proper look before committing either way.
Will new windows make a difference to noise from the West Coast Main Line?
For properties close to the line, yes. Standard A+13 rated double glazing reduces noise as well as heat loss. If you’re within a street or two of the railway, triple glazing is worth considering: our A++21 rated units add a third pane and a wider cavity, which makes a more noticeable difference to low-frequency train noise. Prices for both are available through the instant online calculator.
Do I need planning permission to replace windows in the Old Bletchley conservation area?
Possibly. Properties within the Old Bletchley conservation area may need planning permission for window replacements, depending on the type of change and the materials involved. Outside the conservation area boundary, standard permitted development rules apply and most replacements don’t require permission. Milton Keynes City Council can confirm whether your specific address is affected; checking before ordering is always the right call.
Are composite doors significantly more secure than uPVC?
Both come with multi-point locking and toughened safety glass as standard at Apex, so the security specification is the same. The main difference is the door itself: composite doors have a solid timber or foam core, making them harder to force and better at resisting the kind of impact a determined burglar might try. For front doors on properties in central or east Bletchley, where burglary rates are higher, composite is the stronger choice.
Are you FENSA registered?
Yes. Apex Windows is FENSA registered, No. 31157, which confirms every installation meets current building regulations and energy efficiency requirements. You’ll get a FENSA certificate after the work is complete, which you’ll need if you sell the property later.
Do I need to wait for a salesperson to visit before I can get a price?
No. Apex’s instant online calculator gives you a real price on windows, doors, or conservatories in under 10 seconds, no appointment and no rep on your doorstep. If you’d rather talk it through first, speak to our team directly.
