Replacement windows and doors in England must meet the Building Regulations — a U-value of 1.4 W/m²K or a Window Energy Rating of band B, and no worse than the units they replace. A FENSA- or CERTASS-registered installer can self-certify that compliance and register the work, so you get a certificate without arranging building control separately.
When comparing firms in Letchworth, check the accreditations each one holds, make sure quotes are like-for-like on frame material and glass specification, and get at least three before you decide. Every listing here is an independent local business, so your enquiry goes straight to the firm.
