Flat 415, 1 Coprolite Street, Ipswich, IP3 0BN

Flat 415 is a one-bedroom mid-terrace house in Ipswich (IP3 0BN). It has a recorded floor area of 49 m² (around 523 sq ft), construction records dating it to 2003-2006 and council tax band B. The latest certificate (October 2008) returns a B (score 82), comfortably above the UK average. Main heating runs on electricity. The latest certificate is from October 2008, so improvements made since then won't be reflected.

The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a balcony.

At 49 m² it sits well below the postcode median (72 m² across 54 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 70% of similar EPCs). Across 2004–2015, sale prices on this property compounded at -3.9% per year.
