Over 40 Years Experience in Polishing and Plating.
We are one of the largest and most reputable polishing and finishing companies in Hatton Garden.
Hatton Garden polisher steeped in history
First established in 1927 F. Sinclair Ltd was previously owned by Flo Sinclair before being taken over, in February 1972, by Barry Coumbe and Keith Buckley. Determined to make strong name for themselves within the industry, Barry & Keith worked to perfect a vast repertoire of skills in both polishing and precious metal plating.
As a result, they have built a respectable reputation of being the best polishers in Hatton Garden working with precious metals.
Our skilled team works fast!
Armed with a team of specialist workers, F. Sinclair Ltd prove to be going from strength to strength, upholding their name as the largest polishing company in England. Darren Coumbe, Barry’s son, who has worked in the business for 18 years replaced Keith as Director in 2015. It really is a family-run business.
With his influence and expertise F. Sinclair Ltd continues to provide 100% exceptional service, with an average work turnaround of just 24 hours.
“100% exceptional service, they really are the best polishers in Hatton Garden, without question”
