Recently had a new boiler system put in by High Efficiency Heating and couldn’t be happier! Was no small job the lads had to do either. Ripping out the old system (water tanks etc) and connecting the new system with new pipe work etc. absolutely fantastic job! Very neat and tidy and left our home absolutely spotless when complete. Also took extra care in our babies room laying out sheeting and covering which was really good of them as the room was all brand new. Fantastic from start to finish! Huge thankyou!

The team were very professional and friendly with our boiler installation. They turned up promptly each day with notifications to let me know they were on the way and when they arrived, they explained what would be happening and if there would be any disruptions to the water and electric. They cleaned up the work area each afternoon so the bathroom remained useable by my family. The job was finished in the estimated timeframe and there were no hidden charges. Thank you.

The engineer and his apprentice arrived on time to carry out the work which was to take 3 days in total. Their brief was to remove a 35 year old heating system and replace it with a new system. It entailed taking out the old boiler from a kitchen cupboard, removing 2 water tanks from the loft, taking the cistern out of a bedroom airing cupboard together with all the pipe work where the new boiler was to be situated. Jake and his apprentice worked really hard the whole time they were with us and were skilled in every stage of the job, keeping us informed as the work progressed. I found them very clean and tidy and respectful of our home. At the conclusion, Jake explained how everything worked and how we could contact him if we had any queries. I have no hesitation in recommending this company and their staff for the services they provide and can assure future customers they will not be disappointed.

The transition to our new central heating system from our old freestanding boiler was carried out with the greatest care, efficiency, expertise and professionalism we could have hoped for. From Richard’s first visit to completion by Dylan and his team the whole conversion was undertaken to the exact timescale we were given at the outset and with the minimum disruption to our routine. We cannot thank them enough.
