Housing in Islington
Georgian squares around Barnsbury and Canonbury, long Victorian terraces off Upper Street, and 1960s blocks. A large share of those terraces are now two or three flats, which changes what an assessor is actually measuring.
The borough has a large private rented sector and constant turnover of conversions. Because so much of the stock is a flat inside an older building, the rating reflects the whole envelope rather than anything the individual flat owner has done.
What affects an EPC in Islington
The rating is driven by the building rather than the postcode, but the local stock produces the same issues repeatedly:
- Solid brick walls behind the stucco, which cannot be cavity filled and cap what the rating can reach.
- Single-glazed sash windows in the Barnsbury and Canonbury conservation areas, where replacement needs consent.
- Flats in converted terraces that moved onto electric heating when the gas supply was split, which is one of the largest single penalties on a rating.
A first-floor conversion with electric heaters and single glazing sits close to the worst case on the scale. Where a gas supply can be restored and the roof space above the flat insulated, the rating often moves two bands.
EPCs in Islington: what is required
The rules are national rather than local, but they depend on what you are doing with the property:
- Selling a home — a valid EPC must be commissioned before the property is marketed, not at exchange.
- Letting a property — band E is the legal minimum today, rising to band C from 2030 under proposals not yet in force.
- Marketing for a client — the agent must be satisfied a certificate has been commissioned before the property is advertised.
- Commercial premises — assessed at Level 3 or Level 4, on a separate penalty scale.
Getting to and from Islington
Rail services run from Highbury & Islington, Angel and Essex Road, with services into Moorgate and the City. Our assessors work across the whole area, so appointment availability depends on the assessor's round that week rather than on travel time.
Also needed to let a property here
Most landlords in Islington need two more documents alongside the EPC, and both can usually be arranged on the same visit:
- Gas safety certificate — every 12 months, by a Gas Safe registered engineer.
- EICR — every five years, for the fixed wiring.
