uPVC double glazed windows in Buckinghamshire: what to know

uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.

Modern uPVC casements use multi-point espagnolette locks that engage keeps along the frame, internally beaded glass so units cannot be removed from outside, and key-locking handles. PAS 24 is the security standard expected for easily accessible windows in new homes in England, and it is a sensible benchmark for ground-floor replacements.

Low-level glass needs safety glazing. In England, Approved Document K treats any glazed panel within 800mm of the floor as a critical location, so a full-height pane, a low picture window or glass beside a door usually needs toughened or laminated glass, permanently marked to show its classification.

In England, replacement windows on a house that look similar to the originals usually do not need planning permission. Flats and maisonettes do not have permitted development rights for replacing windows, and listed buildings, conservation areas and homes under an Article 4 direction may need consent, so check before ordering.

What applies in Buckinghamshire

Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.

Buckinghamshire is inland, around 66 km from the nearest coast at its closest point, so salt exposure is rarely a factor.

In terraced streets and flats, old frames are usually removed and new ones fitted from inside to avoid scaffold. Parking for the van, access through communal areas, leaseholder consent and the lack of permitted development rights for flats all need checking before ordering.

Choosing your uPVC windows

Double or triple glazing

Low-E double glazing suits most homes; triple glazing adds a third pane for lower heat loss and quieter rooms, but units are heavier.

Tilt and turn

Opens inwards from the side for cleaning or escape, or tilts from the top for secure ventilation; practical for flats and upper floors.

Woodgrain and colour foils

Grey, black, cream or woodgrain foils on one or both faces, so the frames can match a door or suit an older house.

uPVC sliding sash

Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.

uPVC Windows in Buckinghamshire: questions

Can I fit uPVC windows myself?

You can, but the work still has to meet building regulations. In England and Wales, without an installer registered with a competent person scheme you need building control approval and inspection. Accurate measuring, correct packing, fixing and sealing all affect weather performance and how the locks work, and mistakes are hard to put right because frames are made to size and cannot be returned.

How much do uPVC windows cost?

The cost of uPVC windows depends on the size and number of windows, how many sashes open, the frame colour, the glass and the access. White casements with standard double glazing sit at the lower end, while foiled colours, triple glazing and bay windows cost more. See the guide prices for typical ranges; the written quote fixes the price for your specification.

Will fitting new windows damage my plaster or decor?

Some disturbance is normal, but it is usually limited to the edges of each opening. The glazier cuts out the old frame, fits the new one and finishes the inside with trims, sealant or filler. Older frames set deep into plaster may need some plaster repair, and we flag that at survey so it is covered in the quote.

Are uPVC windows secure?

Modern uPVC windows can be very secure when they have multi-point locks, internal glazing beads, key-locking handles and laminated glass where needed. PAS 24 is the security standard expected for easily accessible windows in new homes in England. Ask for ground-floor windows tested to it, and avoid frames where the glass is beaded from outside.
