MEES 2030 makes it illegal to re-let any rental below EPC C in England and Wales from 1 October 2030. That is around 2.5 million UK rental homes (DESNZ estimate) — every one needs a heat pump, insulation, glazing or solar before that date. The installer who knows where they are wins.

Common questions

Quick answers

What is MEES 2030 and why does it matter?

MEES 2030 is the UK regulation that bans the rental of any privately let home in England and Wales rated below EPC band C from 1 October 2030. It is set by DESNZ and enforced by local authorities — civil penalty up to £30,000 per property per breach. Around 2.5 million UK rental homes (DESNZ estimate) sit below EPC C today, which means roughly four and a half years of retrofit work for every fabric, heating and glazing trade in the country. The deadline matters because it converts a soft net-zero ambition into an enforceable per-property fine. For installers, it is the clearest demand signal in UK retrofit history: a fixed date, a known cohort, and landlords actively looking for the people who can do the work.

How many UK properties are affected by the 2030 deadline?

Around 2.5 million privately rented homes in England and Wales sit below EPC band C today, per the DESNZ estimate published alongside the Government Response of 21 January 2026. That is the cohort that legally must be upgraded to EPC C, registered with an exemption, or removed from the rental market by 1 October 2030. The figure excludes social housing (housing-association and council stock are governed separately), Scotland (different regulations), and Northern Ireland (no MEES regime). Owner-occupied homes are not in scope. Retrofit Radar indexes 17.78 million unique properties across England and Wales — owner-occupied, social and rental — and surfaces the rental subset to installers via tenure and EPC-band filters.

Can I export leads to my CRM?

Yes. Every plan ships CSV export with rich columns — postcode, EPC band, recommended measures, retrofit-priority score, and the registered proprietor where you have unlocked it via HM Land Registry. Solo allows 50 lead exports per month; Pro allows 1,000 per month plus an Excel export with extra columns. The CSV imports cleanly into HubSpot, Pipedrive, Copper, Capsule and most spreadsheet-based pipelines. There is no native CRM integration today — we ship a stable column schema instead, so your import mappings keep working as we add fields. API access is on Pro for installers who want to pull rather than export.

What data sources power Retrofit Radar?

Three open UK government registries, all licensed under the Open Government Licence v3.0, plus paid HMLR title queries passed through at cost. The MHCLG Energy Performance of Buildings Register supplies around 24 million EPC certificates and the underlying recommendations. Companies House supplies director and registered-office details for limited-company landlords. HM Land Registry supplies the registered proprietor for individual landlords at £7 per title query — we pass that fee through, no markup, with 10 free per month on Pro. We deduplicate the lot on UPRN (Unique Property Reference Number) into 17.78 million unique properties indexed. No scraping, no purchased lead lists.
