User friendly website with all the information I needed to make an informed choice.
Competitive pricing.
Once purchased, the post sales service was excellent with accurate information given and a delivery on the exact time and date proposed. The delivery team were friendly, knowledgeable and worked quickly but ensured everything was in order before they left.
Great overall service and I would highly recommend Lifestyle Home Appliances for any electrical purchases.
