Dalen Cooker Services Ltd

The Oilwarm Electric Kit Advanced conversion of our oil fired 2 oven Aga was completed last week by Dalen Cooker Services. The whole process from the initial survey to final ‘switch on’ was expertly carried out in a day by Dalen’s friendly and tidy engineers; Ollie and Kiaran. We expect the conversion to save some money and its controllability is wonderful. We particularly like the separate wall mounted control screen and the Smart Life app for control on a mobile phone.

woke up to an Aga that had 'gone out' Dalen came to the rescue very quickly and even on the eve of a bank holiday managed to get Ollie to visit us and mend it the next day, thank you all at Dalen, especially Ollie, Kieran and Steve.

Highly recommend. They have undertaken work for me across boiler and heating, plumbing and Aga. I have been extremely impressed. They are very knowledgeable, ultra professional, efficient and had a fantastic ‘can do’ attitude when it came to solving any challenges that came up. They have given me complete confidence. Thank you Dalen Services and I will certainly seek your help again in the future.

These are my go-to boys! I have been a client for 10+ years, and I can't recommend them highly enough. I have just had my oil fired Aga converted to the latest Electric Kit Advanced by Dalen's and am very happy with the result. They are always professional, very tidy, informative, and helpful. Solution based in the most practical way. I've recently had boiler problems, and they have been fabulous in helping me in getting the old thing up and working again. I shall need a new boiler. However, having my hot water and heating back in January was a godsend. This has enabled me to sort the long-term boiler problem out in the warmer months! Thank you, Steve, Olly, and Keiran

This was our first visit from Dalen ( for Aga service and chimney sweeping) and I was very impressed. Both the guys were extremely professional, proficient in their work, knowledgable and friendly. We’ll definitely be using them again, I wish I’d found them earlier!
