Blackheath Ward Profile

Introduction

Blackheath is one of Lewisham’s most distinctive wards, renowned for its village character, historic built environment and expansive open heath. The ward combines strong heritage value with a lively local economy centred on its high street, independent businesses and regular events that draw visitors year round.

Cultural assets such as Blackheath Halls and the farmers’ market reinforce Blackheath’s role as a cultural and social hub, while excellent transport links connect it seamlessly to the rest of London. Although often perceived as affluent, Blackheath is home to a varied community, including social housing and diverse age groups, who value the wards sense of calm, green space and strong civic identity.

Through the NCIL 2025–27 programme, a total of £2.55 million was allocated across the borough to support both borough-wide and ward-level priorities. Borough-wide projects received £621,732.92, funding 15 initiatives including four Council-led capital projects such as air quality monitors, deployable CCTV, improvements to Home Park, and a new basketball court at Hilly Fields. A further 11 community-led projects supported a range of residents and community needs, including projects for visually impaired residents, LGBTQ+ communities, refugees and migrants, autistic young people, Black-led organisations, food justice initiatives, employability support, mentoring, parenting support, and arts and performance activities.

Within this wider programme, Blackheath was allocated £104,163.39 in NCIL funding, supporting seven projects in the ward. This included six Council-led capital projects focused on improvements to the public realm and green infrastructure, including bins and benches for the heath, cycle hangars, tree planting and upgrades to a local play area. One community-led project provided support for new parents experiencing financial hardship.

Deprivation

Index of Multiple Deprivation

The Index of Multiple Deprivation (IMD) is the official measure of relative deprivation in England. It is based on multiple factors: income, employment, education, health and disability, crime, barriers to housing and services, and the living environment.

The IMD is determined for small areas called Lower-layer Super Output Areas (LSOAs). Each LSOA is ranked from most deprived to least deprived nationally, and then grouped into ten deciles. Decile 1 represents the most deprived 10% of LSOAs in England.

Of the 10 LSOAs in Blackheath, 0 rank in the bottom 20% of the country (decile 1 or 2).

Household deprivation

Household deprivation is measured across four dimensions: education, employment, health and housing. A household may be classed as deprived if it has low educational attainment, unemployment or economic inactivity due to long-term sickness or disability, poor health or disability, or housing issues such as overcrowding, shared accommodation or no central heating.

Fuel poverty and EPC

Energy Performance Certificates (EPCs) were first introduced in England and Wales in 2007, and are valid for 10 years. They contain information about a property’s energy use and typical energy costs, and recommendations about how to reduce energy use and save money. Dwellings are rated between A (highly energy efficient) and G (highly inefficient.) The average EPC rating for dwellings in England is D.

In Blackheath, 50% of assessed households have received an EPC rating of A, B, or C, which means they are highly energy-efficient. It is estimated that the share of highly energy-efficient dwellings in Blackheath could be as high as 87% if home owners were to carry out the improvements recommended during their assessment.
