1 · What exactly is FENSA?
FENSA (Fenestration Self-Assessment Scheme) is a UK government-approved Competent Person Scheme. It lets registered installers (like Andrews Glass) self-certify that your new windows/doors comply with Part L (energy) and Part K (safety).
2 · Why it matters in Hertfordshire & Essex
| Risk if you skip it | Local reality |
|---|---|
| 💷 House-sale delays | St Albans and Bishop’s Stortford solicitors routinely stall completions until they see the certificate. |
| 🏛️ Council enforcement | East Herts BC can issue a Section 36 notice → up to £5,000 + re-glazing costs. |
| 🏦 Green-loan refusals | Banks in Stevenage & Chelmsford require FENSA proof for eco-mortgages. |

5 · Common myths — busted
| Myth | Reality |
|---|---|
| “I only swapped one pane—no certificate needed.” | Wrong: any frame replacement triggers Part L. |
| “My builder can sign it off.” | Only if they’re FENSA or another Competent Person. |
| “New-builds need FENSA.” | False: new dwellings use NHBC/Building Control, not FENSA. |
