Very professional! No problems, a straight forward process and very efficient & speedy. They even inform you of when they are likely to arrive by enabling you to follow their drive live. It’s all so effortless and they always turn up when they say they will be there. Great service! Thank you!

I've used their services for gas safety certificates and boiler services for many years now and have always found them to be both efficient and prompt in any response.  Definitely recommended.

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

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 am a long standing customer of C4UK & been working with Andras for a number of years. Since starting our relationship, C4UK have provided the same excellent service year in year out and always been able to  complete emergency work at short notice. Great service always.

My shower pump and the kitchen tap needed replacing. Prior to the appointment I got helpful advice on which replacement pump to purchase and the installation was schedule only a few days later. The plumber turned up on the minute, was fast and tidy and the price is reasonable too. I used C4UK a number of times before and can highly recommend their service.

I got them number from a family member who used  them service before, to fix my boiler. The lady over the phone was really nice and sent engineer fast, who diagnosed and fixed my boiler at the same time. He got some spare parts on his van, so made it faster. Price was resonable and service proffesional from the beginning.
Thank you for help

Fantastic service, hones and reliable.
We were given a very reasonable quote to repair our boiler which we appreciated. At the same , we also asked quote for boiler replacement. Several options were offered to suit our budget and we chose to go ahead with new boiler installation. The new boiler was fitted quickly and professionally by Andras.
We really happy with the hole experience.

Highly recommend

C4UK provided outstanding service when my boiler broke down.
They responded quickly and installed a new boiler that works flawlessly. What impressed me most was their attention to detail—they even took the time to reconnect all the old, rusty pipes, ensuring everything was in perfect working order. The team was efficient, completing the job promptly without compromising on quality.

On top of their technical expertise, they were incredibly friendly and professional, which made the whole process completely stress-free. I highly recommend C4UK to anyone looking for reliable, expert heating services. They truly went above and beyond to deliver work of the highest standard.

I had a fantastic experience with Certificates4UK for a major boiler installation in Kingston, including a gas certificate and powerflush. Andreas completed this massive job in just two days with a friendly, professional approach. He even fixed a leaky radiator at no extra charge! All costs and processes were clearly and honestly communicated upfront. I'm delighted with their work and highly recommend Certificates4UK for their expertise and exceptional service!

We’ve used C4UK for a variety of services including gas safety inspections, boiler servicing, and full boiler installations—both for our own home and our rental properties. They’re really easy to deal with and always professional.

One thing we really appreciate is how they send us plenty of photos of the work done, especially when we can’t be there in person. It gives us peace of mind knowing everything is handled properly and to a high standard.

Highly recommended!
