Newmarket: replacement uPVC windows
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.
Bay windows need extra care. Some older bays carry load from the wall or roof above, so the glazier checks the support before removal and may fit bay poles or ask for structural advice. Replacing a window in the same opening is different from widening it, which needs a new lintel.
uPVC no longer means white only. Frames can be foiled in woodgrain or solid colours such as grey, black or cream, often outside only with white inside. Foils are bonded at the factory and should be cleaned with a soft cloth and mild detergent, because abrasive pads and solvents mark the surface.
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.

Newmarket at a glance
- Postcodes covered
- CB8 and the surrounding area, including Mildenhall, Haverhill and Ely
- Coast
- Newmarket is well inland, around 55 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Newmarket the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 61° 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.

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.
What you can choose
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.
Casement windows
Side-hung or top-hung sashes on friction hinges, suiting most houses, with easy-clean hinges that let upper-floor glass be cleaned from inside.
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 Windows in Newmarket: questions
Do I need building regulations approval for replacement uPVC windows?
Yes. In England, replacement windows are controlled fittings, so the work must meet building regulations. An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and you receive a certificate; otherwise approval comes from building control. Wales, Scotland and Northern Ireland run their own systems, and we explain which route applies before work starts.
Can uPVC windows be fitted in a conservation area or listed building?
Sometimes, but consent may be needed first. Listed buildings need listed building consent for significant works, and conservation areas or Article 4 directions often restrict changes to front windows. Woodgrain foils or uPVC sliding sashes can occasionally satisfy a planning officer. Check with your council before ordering; the council can tell you what an application needs, and we can provide product details and specifications to support it.
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.
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.
