The lock arrived undamaged in good in good time. I am not a locksmith but a DIYer and found that the installation was straightforward although you had to take particular care about where internal components are when taking apart to install the barrel. The old lock was a help here. An economic solution.

Prompt service and assistance with my phone enquiry.Order processed very quickly and delivery within days of order.
Cannot fault service

excellent service, I will definitely use them again.

Part recommended by Gainsborough did not fix the problem
I had to alter the gear setup to fix it
Still have part which doesn’t fit the lock barrel on mine .

The trilock body fixed my problem thanks.
