Very helpful and efficient, competitively priced and good quality products. They seem to be extremely responsive and accessible here - I called twice on the phone and was straight through to a helpful person at the other end in moments. Marie was very pleasant and friendly to deal with, all details were confirmed by email quote and delivery was very prompt. I would definitely use BLT again.

Brilliant customer service! Light was replaced when water got in, despite it being out of warranty. Highly recommended.
