Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Highlights
“On first meeting, we could tell that Nathan and his team were friendly , polite and professional. He understood exactly what we wanted and how the end result should look and is very good at explaining everything and putting us at ease. Nathan and team are so reliable, they came everyday as expected and worked very hard at all times. We could happily leave them to get on with it safe in the knowledge they would take good care of our property and the build would be completed to the highest standard. He treated our property like his own. The porch exceeded our expectations in terms of quality. Nathan supplied and used top quality fixtures and fittings. We cannot recommend this company enough and have already booked them for another project.”
“Nathan and his team helped renovate my house following a flood which wrecked everything. We are extremely happy we picked Nathan as it had been such a stressful experience beforehand and he made it that bit easier with his re assurance and great work. Thank you.”
“Rc construction helped convert my side shed building into a home office. Nathan helped design this as well as doing all the work and arranging all the building regulations.”
Detailed reviews
I would like to thank Nathan and the team for carrying out a first floor extension and Kitchen. They were always willing and keen and spotted a couple of issues before it became a problem. Well Done and thank you 😊
Would recommend - very good at what they do.
Fit a conservatory at my house, done a fantastic job.
Overall I’m am very pleased to have gone with RC Construction. We had x 2 30+ year old and very large sky windows. That needed to be replaced. I was anticipating many issues in the removal and installation of new ones. RC construction was booked in and arrived in a timely manner, the work was carried out and to a high standard with no complications. I would recommend and most definitely be using them again.
Nathan took out and fitted our new kitchen everything was done to perfection he was very punctual hard working and very fair priced the job was left clean after every visit would highly recommend and will be using him again in the future

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
