Keystone London Bewertungen 

Excellent service from Keystone. Professional and very reasonably priced. Replaced our leaking radiator valve quickly.

Very professional team, did a great job repairing our boiler when we thought we needed a new one. Would recommend.

Excellent work carried out by very friendly team. Having had a new full heating system installed, very pleased with the results.
Arrived when arranged, very helpful, cleared up after themselves, nothing was too much trouble.
Would highly recommend this company.

very efficient and reliable service, would recommend

Lads came out again for instalation of new toilet. Amazing work, so polite and proffessional. Cannot recomend highly enough.

My experience with Keystone London Group has been extremely disappointing, plumber turned up and it became evident there was a big disconnect with communication between plumber and their own admin team, their whole aspect of their demeanour/representation/ professionalism/communication is terrible and I felt they were making assumptions even in person about my situation instead of listening to the information I provided as a customer, From the start it felt like they were more focused on what they could charge me/cancellation charges rather than understanding the job or even properly assessing the situation first hand. I was not taken seriously, and their approach and the plumber approach made me feel so uncomfortable to the point where I didn’t feel confident letting the plumber into my home today.
This entire experience has left me questioning what Keystone London Group actually represents — whether they are efficient or simply operating like a cowboy company beneath the surface as up to a week of going back and forth with their admin staff with no real progress and constant miscommunication I felt from my end I am now forced to look for another plumbing company to complete the repair I would like to get done.
Their admin team whom has taken my booking/enquiry needs to take accountability for their lack of listening, lack of understanding, and the poor information they passed on to their plumber as they are the first point of contact, they should be setting the standard but in this case, they have completely failed to do so along with due diligence and clarity of care.
Overall, the experience left me with a sour taste in my mouth and I’m unable to move forward confidently with the service.

Speedy, efficient and totally trustworthy !!
Sorted out my long overdue plumbing list without fuss and nothing was too much trouble. Can't wait for another visit !

Daniel & his team have been incredibly easy to liaise with and consistently professional throughout. Communication was clear and prompt, and the team delivered high-quality work with minimal fuss. It’s refreshing to deal with a company that values both efficiency and customer service. Highly recommended!

Prompt and professional. A Quooker filter install was delivered with the wrong parts, Daniel problem solved and committed to finishing the job using his own parts.

Absolutely amazing experience, from Samira on the phone to Daniel turning up (early!) and getting the job done promptly and professionally. He is such a lovely chap and extremely personable. I was so happy, I immediately booked him again for another job 2 days later. Keystone is now my go-to for all my plumbing and gas boiler related jobs.

Daniel is excellent — always professional, punctual, and thorough in his work. He solves issues efficiently and ensures everything is left tidy!

Friendly & timely, repaired rather than automatically replaced!

Urgent job as leak in kitchen pipe.
Came same afternoon and sorted the problem plus checked all was working before leaving.
Very thorough.

Incredibly professional, quick, patient and polite.

Excellent service, thank you. Reliable, efficient & easy to deal with. Highly recommended

Very responsive and helpful, reached out regarding a water pump issue and was able to get it scheduled for the next day. Great value for money as well when compared to other plumbers.

We had an issue with our toilet flush and Daniel really saved the day. He was quick to respond, very accommodating with timing, and came fully prepared with everything needed. The repair was completed within an hour, and he put the wall and furniture back neatly after finishing the job. Daniel was polite, professional, and left everything spotless. Look no further—it’s hard to imagine finding a better plumbing engineer.

Gas cooker disconnection of older appliance and pipe capping was carried out quickly, along with safety checks and relighting gas water heater afterwards.

Visit was arranged at short notice at convenient time.
Recommended!

Really impressed with the new boiler installation. Daniel was friendly, tidy, and explained everything clearly. Hot water works perfectly now

Keystone fitted a new boiler for me on an emergency basis,Dan was great, clean , tidy and polite. Great service.
