Frequently asked about North West London
Do I need planning permission for new windows in North West London?
Usually not for a house that is not listed and not under an Article 4 Direction: like-for-like replacement windows are permitted development. Flats, listed buildings and streets with an Article 4 Direction are the exceptions, and North West London has all three. Check your address on the council register before ordering; our planning permission guide explains how, and we prepare the drawings if an application is needed.
How many windows has Apex Glazing fitted in North West London?
At least 26 completed installations across NW1–NW11 and HA0–HA9 since 2023, taken from our own job records, and that counts only jobs where the postcode was recorded against the deal. Every one was surveyed, manufactured to size and FENSA self-certified.
uPVC or aluminium in North West London?
On a Victorian or Edwardian street, uPVC sash or an aluminium heritage window keeps the look the conservation officer expects. On a 1930s semi, a uPVC casement or bay is the usual answer and the best value. For a rear extension opening, slim aluminium sliding or bifold. The survey settles it; nothing is ordered before it.
What do new windows cost in North West London?
Prices are set by the window, not the postcode. Our London cost guides give fitted 2026 prices per type: uPVC casement from £550, aluminium from £900, slimline sliding doors from £4,500. A survey turns that into a fixed quote for your openings.
Do you cover all of NW1–NW11 and HA0–HA9?
Yes. The districts where we have completed work so far are NW1, NW2, NW3, NW4, NW5, NW7, NW9, NW11, HA2, HA3, HA4, HA5, HA7, HA8, HA9; the rest of the region is the same drive from our base and priced the same. If you are just outside, ask — the map is a guide, not a boundary.
