Boiler installation

I had a great experience with Andy and his cortege from start to finish. Professional, punctual, and very knowledgeable, they explained everything clearly and made sure the work was done safely and to a high standard. The job was completed efficiently, with no mess left behind, and the pricing was fair and transparent. It’s reassuring to find someone so reliable and trustworthy. I wouldn’t hesitate to recommend them to anyone looking for a dependable Gas Safe engineer.

I’m using Andras and his team over 6 years for boiler repair and installation, all landlord certificates and general plumbing too.
As a landlord what I like that I can’t be there and always getting plenty pics from the work was done and showing prices and getting many options when repairs or installation coming to suit for my budget. It’s hard to find someone who can really trust if you not there.
Always on time and never let me down.

Strongly recommend anyone who needs a good engineer

Prompt & reliable

I have been using Certificates4UK for EICR, Gas Safety & PAT tests for several years now across my rental properties.

Always prompt & courteous, and able to get someone in quickly. Manage the appointment directly with tenants to ensure convenient scheduling.

Reports always shared within 1-2 days of the inspection. And no unnecessary additional work.

I’m using them services over 8 years

I’m using them services over 8 years, for certification, all plumbing gas and electric repair and installation and really happy the service they provide.
As a landlord I can’t be in properties so I’m always getting plenty of pictures and videos from faults and parts replaced what it’s makes me feel secure.
It’s easy to deal with Andras, and whoever coming the person always polite and on time and leave tidy work.
I’m attaching my last fuse board replacement what was done and love the collage I got.
