The Mowbray, Flat 22, Borough Road, Sunderland, SR1 1PS

The Mowbray is a one-bedroom detached house in Sunderland (SR1 1PS). It has a recorded floor area of 50 m² (around 538 sq ft), construction records dating it to 2003-2006 and council tax band B. The latest certificate (May 2022) shows a C (score 77), near the top of the C band. Earlier certificates rated it B (August 2009); the latest reading is one band lower. Between certificates, lighting went from Good to Very Good; while hot-water efficiency dropped from Average to Poor and main heating dropped from Poor to Very Poor. The recommended improvements would push it to B (score 84). Main heating runs on electricity. At 50 m² this is the 9th smallest of 37 units on EPC record in The Mowbray, where floor areas span 33–106 m². The building's EPC ratings span D to B across 37 units on file. Other recorded features include a balcony.

Today's modelled estimate of £111,000 is 19.6% below the 2008 sale of £138,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£256/sq ft) was about 46.3% above the typical sold price in the postcode. Held since February 2008 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price.
