Increase Rental Income & Meet MEES, Hassle-Free

We take the guesswork out of retrofit for private landlords. You meet Minimum Energy Efficiency Standards (MEES), without the headache.

Add up to 10% in rental income

Reduce energy bills by up to 40%

Why increase your EPC rating?

It’s Easy with Domna

We take the hassle out of energy upgrades

  • Start small, win big – Our remote assessment ensures you make smarter retrofit choices, and our whole-house approach means we maximise your value.
  • Don’t go it alone – We connect you with trusted installers and provide expert advice (and we’re completely impartial).
  • Use grants to cover the cost – We help landlords unlock funding from schemes worth over £1bn a year.

It’s the Law

Avoid fines and future-proof your portfolio

  • Get ahead of MEES – All rentals must be EPC E or better, and by 2030 that rises to EPC C (2028 for new tenancies).
  • Avoid costly fines – Fines are currently up to £5,000 per property, expected to rise to £30,000 per property by 2030.
  • Take action NOW – Councils are cracking down, and it pays to get ahead before the new laws come into force.

It Adds Value

Boost your returns while cutting tenant costs

  • Get more from your property – Add 20%+ value and 10%+ to rental income with EPC upgrades.
  • Lower bills = happier tenants – Tenants can save 40%+ on energy bills and are more likely to stay.
  • Energy efficiency is good business – A warmer, healthier home
    is easier to rent and easier to sell.
