How the estimate is made
The estimate for 23a is modelled from its 193 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP3 0DH. 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.

About 23a
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
23a is a detached house in Hemel Hempstead (HP3 0DH). It has a recorded floor area of 193 m² (around 2077 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (July 2025) shows a D (score 60), on the cusp of jumping into the C band. When first surveyed in August 2015 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Very Poor to Good; while window efficiency dropped from Average to Poor and lighting dropped from Very Good to Average. The recommended improvements would push it to C (score 74).
Untraded for 29 years, with the last transfer in March 1997. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 193 m² the property is well over the postcode median (116 m² across 15 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs). Today's modelled estimate of £1,121,000 sits 280% above the 1997 sale of £295,000. On a £-per-square-foot basis, the last sale (£142/sq ft) was about 68.6% below the postcode norm. One planning record on file: tree works approved in 2018. Past consents include tree works, meaningful when judging how the property has evolved.

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 23a is modelled from its 193 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP3 0DH. 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. 1 sale is recorded for 23a. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 23a was lodged in July 2025 at band D and is valid until July 2035. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 23a. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point. The 15 schools and 30 stops listed are measured in a straight line from HP3 0DH, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 23a is in council tax band G. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
