Excellent work from Paul. He arrived on time and completed the work and left the area neat and tidy. Will definitely use Paul for future jobs.

I used AGL to decorate my 5 bedroom house in W12 in April 2014. The standard of the work was excellent. They are experienced and were able to come up with practical solutions to issues that arose. They were able to carry out addition electrical and plumbing work. Their quote was competitive and transparent. They repsonded promptly to calls and emails. AGL were trustworthy and reliable and I have since made several recommendations to friends. I would definitely use them again.

Fantastic work. Andy is very professional and knowledgeable. Prompt, friendly and very competitive prices. We are building a 2 storey side extension and Andy is doing all the building works. We have a very difficult set of footings which involves a line of trees close by. Foundations passed by Building Control with flying colours. Very satisfied and Andy will be quoting for other work I have planned and I am sure we will be working together for sometime now. Would recommend him to anyone.

Great work. Delivered the brief in the timeframe and on budget. Left them to get on with it and they sorted the whole thing without any hassle.

After speaking with several Builders, I decided to select them. They turned up smart professional listened and approach the job with professionalism. They were always open to listen and kept in touch with me daily, worked to my schedule and finished the job on time full house refurbishment outside roof walls, windows doors and patio in two weeks. Very easy to work with and respectful builders who do what they say they’re going to do and to a good quality so I would definitely recommend them 100%

Prompt response to my request for quote; reasonable pricing; value-add to the design process; very good quality execution of the work and final bill matched the quote. Highly recommended!

Although it turned out that there was no leak only the condensation caused the problem, I got a professional advice and for free! Will definitely call them back!

This job was paid for in full, and since being done I have had another company out to refit and replace doors. You were paid in full - it's strange how it's taken 6 YEARS for you to answer the review!?!?!?!

We have not gone ahead with his quote but Piotr was excellent at contacting me and keeping in touch with regard to the appointments made for him to come and view the work. He was very friendly and professional and listened to what we wanted/needed and came back with a quote within a couple of days. I would have liked the quote to be a bit more detailed and ‘professional’ looking – but this was not the reason we decided not to work with him. I wish him luck with other jobs.

Speedy response a day after posting to replace kitchen tap and cistern mechanism. Ryan and Jamie arrived swiftly, they were very courteous and carried out the work efficiently without any fuss. Would highly recommend and use again.

Martin was quick to make contact with me and arrange a time to quote. He came to my house with his wife and they were able to give me really good advice and a quote on the spot which was appreciated. I didn't use Martin on this occasion more due to my own timings then anything else but would certainly look to contact him in the future for any other jobs required.

They were very dodgy and unreliable. They took all the agreed money but never came back to finish the job. I was left without a kitchen, cooking utilises and drinking water for two whole months as no other builders were willing to pick up the mess they left behind. The garden was a complete mess with concrete and heavy building rumble. I strongly advise people to be wary of hiring them.

Did not get this company to do my job..could not in honesty let someone come to my house to do a job who didn't want to look at, or measure anything but knew it would cost £800 To do it...absolutely ridiculous, but not the only company on this site who try it on.
