Energy Performance Certificates in Gravesend

Common property types

• Victorian terraces: Concentrated around the town centre, particularly along Windmill Street, Parrock Street, and the streets surrounding the Heritage Quarter. These two- and three-bedroom terraced houses were built with solid 9-inch brick walls. no cavity, no insulation. Most have bay windows at the front, sash windows (many now replaced with uPVC), and chimney breasts that may or may not still be in use. These properties typically score E or F on EPC assessments, with solid wall insulation being the main recommendation for improvement.
• 1930s semis in Northfleet and Singlewell: The suburban expansion of the 1930s brought rows of three-bedroom semi-detached houses to areas south and west of the town centre. These cavity-wall properties are generally good candidates for insulation if it has not already been done. Many have had extensions, loft conversions, or new boilers fitted over the years, which can either help or hinder the EPC rating depending on the quality of the work and whether building regulations were followed.
• Modern riverside developments: New-build flats and apartments along the Thames waterfront, built from the 2000s onwards as part of Gravesend's regeneration. These properties typically achieve B or C ratings thanks to modern building regulations requiring high insulation standards, efficient gas or electric heating, and double glazing throughout. They rarely need improvement work to meet current landlord requirements.
• Ex-council flats in Northfleet: Purpose-built council blocks from the 1950s and 1960s, many now in private ownership. These are typically concrete panel construction with flat roofs. Some still have the original electric storage heating, and communal areas can complicate assessments. Each self-contained flat needs its own EPC when sold or let.
• New-build houses around Ebbsfleet: The ongoing development around Ebbsfleet Valley has brought modern family homes built to recent building regulations. These properties generally achieve B or C ratings as standard, with good insulation, efficient boilers, and double glazing throughout.
• Longfield 1960s-70s detached houses and bungalows: The DA3 postcode south of Gravesend includes a mix of detached family houses and bungalows from the 1960s and 1970s. Construction is typically brick cavity wall with concrete tile roofs. Many have been extended or modified over the decades. Bungalows often have accessible loft spaces that are straightforward to insulate, while the detached houses sometimes have had conservatories added that the assessor will check.

Typical EPC issues we find in Gravesend

• Solid wall Victorian terraces: The absence of a cavity in pre-1920s terraces is the single biggest factor in poor EPC ratings across central Gravesend. Internal wall insulation is the most practical option but requires replastering and reduces room sizes slightly. External insulation is rarely used on terraced streets due to planning constraints and shared boundaries.
• Damp in riverside and low-lying properties: Properties close to the Thames or in low-lying areas of Northfleet can have damp issues that affect both the building's condition and the EPC assessment. Rising damp compromises the effectiveness of any insulation installed at ground level, and assessors need to note evidence of moisture when recording construction details.
• Flat roofs on 1960s-70s extensions: Many older properties in Northfleet and Singlewell have had flat-roof extensions added over the years. These extensions often have minimal insulation and are recorded separately from the main pitched roof, pulling the overall insulation score down.
• Poor ventilation in converted flats: Victorian terraces near the town centre that have been split into flats can have inadequate ventilation, particularly in kitchens and bathrooms. While not directly scored in RDSAP, evidence of condensation and mould can indicate underlying issues that affect the building fabric and how the assessor records wall and window conditions.
• Old Economy 7 heating in ex-council stock: A number of former council properties across Northfleet and the town centre estates still have Economy 7 electric storage heater systems. These score significantly worse than gas central heating in RDSAP methodology and are one of the most common reasons we see E and F ratings in the DA11 and DA12 postcodes.
