Stovefitters- second to none!!

Stovefitters warehouse have been brilliant!
We sent Julian some simple drawings and measurements and he designed us the perfect systems for two wood burning stoves, complete with list of parts and a computer produced diagram of the finished article. They then put the order together which we received promptly and we’ll packaged. Great British made quality too! The twin wall Duraflue is very nicely made with very clean lines and is very simple to install.
We changed our mind a couple of times but nothing was too much trouble.
Julian and Arran dealt with our issues promptly and very professionally. Their knowledge about stoves and flues is second to none!
We are extremely pleased with the goods and service we received. We would not hesitate in recommending them to family and friends. They work very hard and customer satisfaction seems very high on their list of priorities.
All now installed the stoves look and perform great! Thank you to all Stovefitters Warehouse!

Quality product, great advice and delivered quickly

I ordered a few different twin-wall components for my installation after speaking with one of the guys at The Stove Fitter's Warehouse for advice. After a run through of my installation queries over the phone, I received great advice and help with my order.

Full package

Ordered full package from Julian and his team at Stovefitter. Customer service was second to none and communication was excellent. Also the quality and packaging of goods were second to none. His Stovefitter manual, gave me the confidence to install myself and my whole family are really pleased with the result. Once again thanks all.
