/ Why Certified

Why choose an MCS-certified installer?

MCS certification is the UK's only recognised quality standard for renewable energy. Without it, you cannot access government grants.

  • Boiler Upgrade Scheme — £7,500 grant

    Only MCS-certified installers can apply for the BUS grant on your behalf. The £7,500 discount is applied upfront — no claim paperwork for homeowners.

  • Vetted & independently certified

    Every installer on our directory is cross-referenced against the live MCS public register. Certification is renewed annually and covers workmanship standards, equipment quality, and customer service.

  • Exclusive local matching

    We match you to certified professionals who actively work in your area — reducing travel costs and ensuring they know local planning and grid connection rules.

  • Free project assessment — worth £380

    Your matched installer visits your home, surveys the project, and provides a written recommendation. Normally charged at £380; free through Renovation Register.

  • Smart Export Guarantee eligible

    MCS-certified solar PV installations qualify for the Smart Export Guarantee (SEG), meaning you earn money for surplus electricity exported to the grid.

What homeowners say

Homeowners across the UK use Renovation Register to find their MCS-certified installer. Here are a few of their experiences.

  • I'd been putting off getting a heat pump for years — I wasn't sure who to trust. Renovation Register matched me with a local MCS-certified installer within a day, and the free home assessment made the whole decision feel completely stress-free.

    Sarah M. Bristol · Air source heat pump

  • Our solar PV system was installed just six weeks after we first used Renovation Register. The installer was transparent about costs from the start, and we were able to claim the Smart Export Guarantee straight away. Genuinely impressed.

    James T. Leeds · Solar PV

  • The battery storage system has transformed how we use our solar panels. Renovation Register's free assessment confirmed we'd be eligible for a grant — I had no idea that was even possible. The whole process took less than two months.

    Anya P. Cardiff · Battery storage

  • We wanted a ground source heat pump but couldn't find anyone credible locally. Renovation Register found us a certified specialist in Manchester who knew exactly what planning rules applied to our property. Outstanding service.

    Robert H. Manchester · Ground source heat pump

  • What struck me most was how knowledgeable the installer was about the Boiler Upgrade Scheme. Renovation Register matched us within 24 hours and the £7,500 grant was applied directly — we didn't have to do a single bit of paperwork ourselves.

    Fiona G. Glasgow · Air source heat pump

  • I was sceptical about solar thermal, but the free assessment showed us exactly how much hot water we'd generate year-round. The installer was genuinely MCS-certified — you can look it up on the register. Highly recommend Renovation Register.

    David W. Sheffield · Solar thermal

  • Our Victorian terrace in Norwich is now properly insulated — warm in winter and cool in summer for the first time ever. Renovation Register made finding a certified installer quick and painless, and the whole thing was free to organise.

    Catherine L. Norwich · Home insulation

  • Reading is well covered on Renovation Register — three certified solar installers were available in our area. The assessment report was thorough and the payback calculation gave us the confidence to go ahead. Would use again.
