Energy Performance Certificates in Catford

Common property types

• Victorian terraces around Rushey Green: The streets between Rushey Green, Sangley Road, and Catford Hill are packed with two-storey Victorian terraced houses built between 1880 and 1905. These properties have solid brick walls, slate roofs, and front bay windows. Two and three-bedroom configurations are the most common, and many have had single-storey rear extensions added over the years. Solid wall construction keeps EPC ratings low, with most scoring D or E. A good number have been converted into flats, each of which needs its own certificate.
• Edwardian semis near Catford Bridge: The roads around Catford Bridge station, including Canadian Avenue, Bromley Road, and Sangley Road south, have larger Edwardian semi-detached houses with three or four bedrooms. These feature front bay windows, tiled paths, and decorative plasterwork. Wall construction varies between solid brick and early cavity, and this distinction has a significant impact on the EPC rating. Those with cavity walls that have been filled can reach a mid-D, while solid-walled examples tend to score E.
• Bellingham Estate: Built in the 1920s by the London County Council, the Bellingham Estate is one of the largest cottage estates in London. The houses are predominantly two and three-bedroom terraces and semis with rendered walls, pitched roofs, and front gardens. Construction is a mix of brick cavity and early concrete block. Many properties were sold under Right to Buy and are now in the private market. The estate has a distinctive garden suburb character, and the varied construction methods require careful assessment.
• Downham Estate housing: The Downham Estate to the south was built slightly later than Bellingham, in the late 1920s and 1930s. It features similar cottage-style houses but with some variation in design. Properties along Downham Way and Bromley Road are typically three-bedroom semis with cavity walls and generous rear gardens. Many have had extensions, loft conversions, and replacement windows fitted over the decades, creating a mixed picture for EPC assessments.
• Purpose-built flats and maisonettes: Scattered blocks of 1960s and 1970s flats exist around Catford town centre and along Bromley Road. These are typically brick or concrete-framed with flat or low-pitched roofs. Heating systems vary from gas central heating to electric storage heaters. Some blocks have benefited from council improvement programmes, but others remain largely unmodified.

Typical EPC issues we find in Catford

• Solid walls in Victorian terraces: The terraces around Rushey Green and Sangley Road are solid brick construction. Wall insulation is the biggest recommended improvement on these properties, but the cost and disruption of internal or external insulation means many owners do not proceed. Without wall insulation, the rating is unlikely to get above E.
• Unfilled cavities on the Bellingham and Downham estates: Many estate properties have cavity walls that were never filled. Cavity wall insulation is relatively cheap and can improve an EPC by one or two bands. It is one of the first improvements we recommend for these properties.
• Old boilers in the rental sector: Catford has a busy rental market, and many buy-to-let properties have ageing boilers. Replacing a boiler over 15 years old with a modern condensing model typically improves the rating by one band and can be the difference between meeting or failing the minimum E requirement.
• Loft insulation below 270mm: Both Victorian terraces and estate houses commonly have some loft insulation, but often only 50-100mm. Topping up to the recommended 270mm is one of the cheapest improvements available and is consistently recommended on Catford EPC reports.
• Rear extensions with flat roofs: Single-storey rear extensions are common across Catford, particularly on the Victorian terraces. Most have flat felt roofs with little or no insulation. Adding insulation during a re-roof or from below with rigid board is an effective and affordable improvement.
