EPC Lambeth — £79.99 same-day Elmhurst certificate.

From 1 October 2030 every in-scope tenancy in Lambeth must hit EPC band C under the unified deadline confirmed in the Warm Homes Plan response (January 2026). Properties below C cannot legally be let unless an exemption is registered. Landlords are required to spend up to £10,000 per property on relevant improvements; penalties run up to £30,000 per breach. We assess and tell you the cheapest path to C — usually LED swap, loft top-up and smart heating controls.

10 years for the same property across SE11, SE24, SW2, SW4, SW8, SW9 — unless you carry out material works (extension, new heating system) that could change the rating. Letting agents in Lambeth typically renew at marketing time even if not strictly required.

For most South London period stock: full LED lighting, 270mm loft insulation top-up, smart thermostat, and TRVs on every radiator. Together those four upgrades move most D-rated Lambeth flats to C without touching glazing or external walls.

Yes — EPC + Floor Plan saves 20%; EPC + EICR + CP12 (full landlord pack) saves 15%. One visit, one report bundle, one tenant disruption — significantly cheaper than booking each contractor separately.

Yes — many properties in Lambeth sit in conservation areas with listed-building restrictions on external work. Our Elmhurst-accredited assessors apply the correct RdSAP exemptions and document conservation constraints so the certificate reflects realistic upgrade options.

Cost-cap (you have spent £10,000 per property — or 10% of value under £100k — on relevant improvements without reaching band C), third-party consent refusal (tenant, mortgage lender, freeholder, planning) and listed-building / conservation. We document the supporting evidence and register the exemption on the PRS Exemptions Register — valid for 5 years across all Lambeth lets.
