I can't fault the service provided by Andy and his team. They turned up at the pre-arranged time and completed the job with a minimum of fuss. I knew I was is safe hands when Dean arrived at 08:00 and immediately started to cover floors and work surfaces with a protective plastic covering. Dean and Andy worked constantly from the moment they arrived to the moment they left at 17:00, ensuring the job (fit a new boiler, change a radiator, and remove an airlock from a downstairs radiator) was completed in one day. To say I was delighted with the standard of work completed would be an understatement. The follow up care was also spot on - the registration documents arrived from Worcester-Bosch a couple of days later, as did the Gas Safe certification. If you want a company who do what they say they will do at the time they say they will do it then A J Marsden Ltd. are an excellent choice.
