Domestic Energy Performance Certificates across Bexley, Havering, Hillingdon, Sutton, Kingston and the Croydon fringes — suburban semis, detached houses and bungalows, assessed by an Elmhurst Energy accredited assessor and lodged on the national register.
The local stock
The outer boroughs are where London stops looking like London. Bexleyheath, Sidcup, Welling, Hornchurch, Upminster, Uxbridge, Hayes, Worcester Park, Chessington and the Coulsdon and Sanderstead fringes of Croydon are dominated by interwar and postwar semis, detached houses and bungalows on plots that would be unimaginable in Zone 2.
Two things follow from that. The first is that these houses have more exposed external wall and roof than a mid-terrace or a sheltered flat, so the fabric matters more — an uninsulated loft or an unfilled cavity costs real points. The second is that almost every standard improvement is genuinely available. Cavity fill, loft top-ups, floor insulation, external wall insulation on a postwar non-traditional house, even an air source heat pump where there is garden space for the unit: the recommendation report stops being theoretical.
Bungalows deserve particular mention. Their roof area is enormous relative to floor area, which makes loft insulation the dominant single factor in the rating. A well-insulated bungalow can score surprisingly well; a poorly insulated one falls further than owners expect.
Letting: MEES requires band E or better, with fines up to £5,000, and a valid EPC is needed before serving a Section 21 notice. The certificate lasts 10 years from lodgement on the national register.
Also serving South London and East London.
Practicalities
Driveways and off-street parking mean no permits, no loading restrictions and no waiting for a concierge, so appointment times are more flexible than in the central boroughs. Landlords and agents with several properties in the same area can often have them covered in one trip.
Letting it out? Add an EICR or an inventory and check-in.

Common questions
It depends on the size and location of the property — a two-bedroom bungalow in Sidcup and a large detached house in Upminster are different jobs. Send the postcode and bedroom count by WhatsApp or the quote form and we'll reply with a fixed quote.
A bungalow has a very large roof area relative to its floor area, so heat loss through the roof counts for far more than it does in a two-storey house. Loft insulation is usually the single most effective improvement available, and an under-insulated or partly boarded loft shows up clearly in the result.
Generally yes. Interwar and postwar stock usually has a fillable wall cavity and an accessible loft, and detached and semi-detached houses on larger plots have the external space that external wall insulation or a heat pump would need. Those options simply do not exist for most inner London flats.
Usually. Off-street parking and driveways mean no permit or loading restrictions to work around, so appointment times are more flexible than in central boroughs and a run of properties in the same area can often be covered in one trip.
