Domestic Energy Performance Certificates across Ealing, Hounslow, Hammersmith & Fulham, Brent, Harrow and Hillingdon — mansion blocks, period conversions and Metroland semis, assessed by an Elmhurst Energy accredited assessor.
The local stock
West London runs from dense inner-city terraces out to genuine suburbia in a single sweep. Around Fulham, Hammersmith, West Kensington and Barons Court the defining types are the Victorian terrace and the red-brick mansion block — solid brick, generous ceiling heights, and flats that sit surrounded on several sides by other flats. That sheltering usually helps the rating more than the solid walls hurt it.
Ealing and Chiswick add Edwardian villas and large houses long since split into conversion flats, plus some of London's most tightly protected residential fabric. In Bedford Park, Brentham Garden Suburb and the Ealing conservation areas, replacing original timber sash windows or adding external wall insulation is rarely straightforward — which changes the improvement advice, even though it does not change the assessment itself.
North and west of that, Harrow and Hillingdon are Metroland: interwar bay-fronted semis in Ruislip, Eastcote, Rayners Lane and Pinner, mostly cavity-walled with proper accessible lofts. Brent covers both worlds, from Kilburn conversions to Wembley's newer apartment stock.
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. Conservation-area period flats are the ones most likely to need a considered improvement plan rather than an obvious fix.
Also serving North West London and Central London.
Improvement advice
When replacement glazing and external insulation are off the table, the recommendation report still has room to work.

Common questions
It depends on the size and location of the property — a mansion block flat in Barons Court and a detached house in Northwood are very different visits. Send the postcode and bedroom count by WhatsApp or the quote form and we'll reply with a fixed quote.
It does not change how the property is assessed, but it changes which recommendations are realistic. In Bedford Park, Brentham or the Ealing and Chiswick conservation areas, replacement windows and external wall insulation are often restricted, so secondary glazing, loft insulation and heating upgrades become the practical route to a better band.
As individual dwellings. The assessor records your flat's floor area, exposed walls, glazing and heating, plus how the flat sits in the block — mansion flats with neighbours above, below and to both sides have relatively little exposed surface, which often works in their favour despite the solid brick walls.
They can. Interwar semis in Ruislip, Eastcote, Rayners Lane and Pinner usually have a wall cavity and an accessible loft, so the two cheapest insulation measures are both available. The drag is normally an ageing boiler or original windows rather than the structure itself.
