About 25 Castle Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
25 Castle Street is a two-bedroom end-of-terrace house in Newport (NP20 2DF). It has a recorded floor area of 67 m² (around 721 sq ft), construction records dating it to 1930-1949 and council tax band B. The latest certificate (November 2014) shows an E (score 49), well below the UK norm with real room to improve. When first surveyed in July 2013 the rating was G, the property has climbed 2 bands since. Between certificates, roof efficiency went from Average to Good, hot-water efficiency went from Very Poor to Good and lighting went from Good to Very Good. The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from November 2014, so improvements made since then won't be reflected.
Across 2007–2015, sale prices on this property compounded at -1.9% per year. Today's modelled estimate of £135,000 sits 74% above the 2015 sale of £77,585. On a £-per-square-foot basis, the last sale (£108/sq ft) was about 35.3% above the typical sold price in the postcode. At 67 m² it sits well below the postcode median (104 m² across 19 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 84% of similar EPCs). Last sold in April 2015, so it's been off the market for around 11 years.

Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 25 Castle Street is modelled from its 67 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NP20 2DF. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 25 Castle Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC

The latest one for 25 Castle Street was lodged in November 2014 at band E and expired in November 2024, so a new one is needed to sell or let. 5 certificates are on record, which shows how the home has changed.
