Jonathon Hart2026-02-21An amazing overall experience with Bibash and the team. His attention to detail is top notch and takes pride in the work he does. He listened to all our specific requirements and was very accommodating with any last minute design changes. He kept us informed all the way through the process and sometimes worked late into the evening to get the job done. If any small issues accrued during the renovation he was quick to fix it. After the work finished we called him as we had a very small issue with slow drainage with one of the bathrooms. He was quick to arrive and fix the issue. Overall it was a fantastic experience and would recommend him to my family members and any future jobs we have. We are very pleased with our new bathroomTrustindex verifies that the original source of the review is Google.
AnotherCupofTea2026-02-14Keshar came to disconnect our old boiler so another party could come install a new one. We ended up with Keshar also being the one to install our new boiler when that other party ended up not being so reliable and we turned to Keshar instead at short notice. He is responsive when you reach out to him, he gives advice but also listens to our wishes, he does the work efficiently, he has a good vibe and tries to leave minimal impact to clean up afterwards and he does a good job and if there is something a little amiss he will come back and correct it. Would definitely recommend.Trustindex verifies that the original source of the review is Google.

- Leaking or Dripping – Damaged seals, corroded pipes, or faulty valves can cause water leaks.
- Thermostat Issues – Inaccurate readings can result in inconsistent heating.
- Radiators Not Heating Evenly – Usually caused by sludge or trapped air in the system.

FREQUENTLY ASKED QUESTIONS
Can I service my own boiler?
Fixing your boiler is risky if you're not a Gas Safe engineer. The Gas Safe Register is there for a good reason, and the risks are too great. Gas can be dangerous, so stay away from it unless you're Gas Safe!
How often should a home boiler be serviced?
It's necessary to have your boiler inspected every year to make sure it's working fine and doesn't have any water or gas leaks. If you skip this, your boiler might not work well, it could stop working, or you might lose the warranty.
Is a boiler service worth it?
Keeping your boiler in good shape is important for making it work better. If you regularly check and fix any possible problems, you can prevent your boiler from breaking down. To keep your boiler warranty valid, it's recommended to get it serviced every 12 months.
What does a full boiler service include?
Every year, a engineer will begin by visually inspecting the boiler and pipes to make sure they are installed and positioned correctly. After that, the technician will check if the boiler is working properly and identify any initial issues. Following this, they will take off the boiler casing to examine its parts.
