uPVC casement windows in Hatfield
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.
In England, Approved Document L sets the standard for a replacement window in an existing home: a U-value of 1.4 W/m²K or better, or a Window Energy Rating of band B or above. The new window should also be no worse than the one it replaces. The other UK nations set their own figures.
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.
The price of uPVC windows depends mainly on size, the number of opening sashes, frame colour, glass specification and hardware. Bay windows, openings that need a tower or scaffold, and difficult removal of old frames add labour. See the guide prices for typical ranges; your written quote fixes the exact figure.

Local details for Hatfield
- Postcodes covered
- AL9, AL10 and the surrounding area, including Welwyn Garden City, St Albans and Potters Bar
- Coast
- Hatfield is well inland, around 53 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Hatfield the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 hours in midsummer. uPVC frames are bulkier than aluminium, so they take a little more glass area from small windows. On south and west elevations, solar-control or neutral low-E glass limits overheating, while north-facing rooms benefit from high light-transmission glass and warm-edge spacers that reduce condensation.
- Access and setting
- Older rural cottages often have irregular openings, thick walls and timber lintels, so every frame is measured individually and the support above each opening is checked. Exposed hillside and open-field sites benefit from reinforced frames and careful sealing against driving rain.
- Rules in England
- 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.

Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
Options to choose between
Obscure and acoustic glass
Patterned or satin glass for bathrooms and street-facing rooms, and laminated acoustic glass to reduce traffic noise.
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.
uPVC sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
uPVC Windows in Hatfield: questions
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.
What guarantee comes with new uPVC windows?
Manufacturer guarantees apply to new frames, sealed units and hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered and for how long before you commit. Keep this paperwork with your building regulations certificate, because buyers' solicitors usually ask for both.
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.
Do new uPVC windows need trickle vents?
In England, usually yes. Approved Document F expects ventilation after window replacement to be no worse than before, which normally means trickle vents in the new frames. Our glaziers record the existing ventilation at survey and specify vents to suit each room. Rules in the other UK nations differ, so the detail is confirmed for your address.
