Measure the brick opening at three points across and three points high, take the smallest of each, then deduct your fitting gap (usually 10mm overall each way) to give the frame size you order.
Regulations for jobs in Welwyn Garden City
Replacement windows in England should meet Approved Document L: a U-value of 1.4 W/m²K or a Window Energy Rating of band B. Approved Document F expects background ventilation to be no worse than before, which usually means trickle vents. Glazing in critical locations must break safely, be robust or in small panes, or be permanently protected under Approved Document K, which in practice usually means toughened or laminated safety glass. Rooms that need an escape route may need an escape window under Approved Document B. Replacing windows is notifiable building work: the installer self-certifies through a competent person scheme such as FENSA or Certass, or the work goes through building control.

Do I need a trade account to order uPVC casement windows for a job in Welwyn Garden City?
Yes, trade prices are for account holders. Applying is quick, and you can send your schedule for pricing while the account is set up.
Can I collect instead of having uPVC casement windows delivered to Welwyn Garden City?
Orders are delivered rather than collected. If collection would help on a particular job, ask and we will say whether it can be arranged.
Is there a minimum order for Welwyn Garden City?
There is no minimum number of items, but small orders may carry a delivery charge that makes it worth grouping jobs together.
Do the windows meet building regulations?
They can be specified to meet the thermal values in the building regulations for where the job is, with trickle vents, safety glass and escape hinges added where the regulations call for them. Your installer is responsible for any notification or approval the job needs: in England and Wales usually through a competent person scheme; in Northern Ireland through council building control; in Scotland, replacement windows in a house do not normally need a warrant but must meet the standards.
