After having problems with our ageing Oil Boiler, we contacted DW Dunn to see if they could help. Their response was immediate and Andy came out and ran through our options. A formal quote followed quickly and Ian arrived to help sort an immediate... problem as well as giving further advice. We opted to have a new Boiler installed which was completed by Dan and Mark who both did the job very professionally and quickly.This is the first time we have used the Company and are very impressed with every aspect of their service. We will continue to use them for servicing and any other plumbing jobs which may arise.Highly recommended.read more

If the rest of Britain worked as well as Andy and his team we wouldn't be in the mess we're in. Dan, Dan & Tyler were exceptional. This was a very difficult installation and needed a practical, creative, aesthetic approach, they delivered on every... element. Always tidy, quick, technically superb and with good humour, and a bit of fun too. We've gone from an archaic, expensive (to run) boiler to a new, efficient, high tech system. Tim installed the Hive control system brilliantly, everything is now run from my phone, couldn't be happier. We chose DW Dunn due to the great job with a previous installation of a water softener last year, once again a huge success and although the outlay seems expensive, it has proved to be great value. All the best to the DW Dunn team. 10/10.read more

We recently had a replacement water softener installed and a kitchen tap replaced. Despite some challenges these were all overcome with good humour and a positive attitude. A great job done. I would recommend Andy and the team at DW Dunn to everyone ?
