Cyfanedd Uchaf, Arthog, LL39 1LX
About Cyfanedd Uchaf
Cyfanedd Uchaf is a five-bedroom detached house in Arthog (LL39 1LX). It has a recorded floor area of 249 m² (around 2680 sq ft) and construction records dating it to before 1900. The latest certificate (May 2021) shows a C (score 70). When first surveyed in June 2015 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Very Poor to Good, window efficiency went from Average to Good and lighting went from Good to Very Good. Main heating runs on electricity. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a balcony and attached land beyond the plot. Period features are noted in the property record.
It hasn't traded since April 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 249 m² the property is well over the postcode median (139 m² across 4 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 75% of similar EPCs). 5 bedrooms is on the smaller side for this postcode, where 7 is the typical count. One planning record on file: solar panel installation approved in 2012. Past consents include solar panel installation, meaningful when judging how the property has evolved. Today's modelled estimate of £556,000 is 14.1% above the 2008 sale price.
