Winter light in Llanelli
At Llanelli’s latitude the heating season runs for several months and the winter sun is low (about 15° at noon on 21 December), so the warmer inner pane of triple glazing is noticeable.
Rules in Wales
Wales requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.
Before ordering: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.
How it works
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

Questions
Do I need planning permission in Llanelli?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent. Check whether your street is in a conservation area before changing the style.
Which frame is best for a house in Llanelli?
It depends on the house rather than the town: uPVC for value, aluminium for slim frames and big panes, timber for period homes, alu-clad timber for low upkeep. Our surveyor will talk through the options.
How long does fitting take in Llanelli?
Most homes are fitted in 1 to 4 days once the windows are made; manufacture takes about 4 to 12 weeks depending on the frame.
How much does triple glazing cost in Llanelli?
Our guide prices are the same UK-wide: triple glazed uPVC windows from £695 each and a 3-bed semi from £9,395, fitted and inc VAT.
