About Cartmell
Cartmell is a three-bedroom detached house in Summerbridge, Harrogate, Harrogate (HG3 4HT). It has a recorded floor area of 136 m² (around 1464 sq ft), construction records dating it to 1967-1975 and council tax band D. The latest certificate (January 2024) shows a C (score 75), near the top of the C band. When first surveyed in July 2021 the rating was E, the property has climbed 2 bands since. Between certificates, wall efficiency went from Average to Good, hot-water efficiency went from Very Poor to Poor and lighting went from Average to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would lift it to A (score 100), a 2-band jump. Main heating runs on electricity. Other recorded features include a conservatory and attached land beyond the plot. Our model identifies extension potential, subject to local planning policy.
At 136 m² the property is well over the postcode median (78 m² across 14 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 79% of similar EPCs). One planning record on file: an extension approved in 2023. Past consents include an extension, a porch and partial demolition, meaningful when judging how the property has evolved. Today's modelled estimate of £418,000 is 34.8% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£212/sq ft) was about 17% below the postcode norm. Sold December 2021 for £310,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
