From start to finish, it was a pleasure to work with the Nissl team. Their quote was by far the most reasonable, and the quality of work was outstanding – everything delivered on time and on budget, as promised. I was one of those annoying customers that had a lot of questions and went back and forth on decisions, but Callum and his team were always so helpful and accommodating. Couldn’t recommend them enough!
Hydronic Heating boiler unit died on Sunday evening in August. We called two service teams early Monday morning - both had previously serviced our boiler and panel. Both responded can't get there until Tuesday (house is freezing). Called three other providers (one whom represents same day service) and no luck. Wife discovered Nissl and they arrived at our house within 3.0 hours - brilliant! Jake (owner) assessed boiler and got it working but advised it's on its last legs - given age of boiler was 23 years, perhaps time to replace! Nissl quoted on a couple of units and were able to install a new boiler within 72 hours. Jamie (Tradesman - installer) was highly courteous and professional. Could not have been happier and will only use Nissl team to service boiler and panel units going forward. Sincere thanks to highly professional, no fuss, Nissl team!
Very impressed with overall service and price for our hydronic heating installation. Highly recommended
We have just had the hydronic system installed for our house in Kew. Best price in the market (according to our research/comparing with others); very professional services, and on time. Highly recommended!
Installed a Hydronic Boiler- Very competive pricing, excellent service. Delivered on their promises which is a breath of fresh air. Would definitely recommend them no probs. 👌
