Nicholson Heating Services
Contacted Nicholsons heating to get a quote for a new combi boiler, arranged visit/and got quote with in 3 days. Arranged to have a Baxi 836 boiler with hive thermostat fitted the following week. The boiler was fitted quickly and with minimum disruption, the lads were professional and friendly, they double checked all the radiators and valves around the house. The outside work was clean and tidy as needed an condensation trap fitted under my decking. Will certainly recommend for the high quality and friendly service.

We purchased an Atag combi boiler from Nicholson Heating Services Ltd in 2017. The boiler was expertly fitted by them and has been serviced by Nicholson every year since. We are delighted with the boiler and the professional manner of the company.
We would highly recommend Nicholson Heating Services Ltd to any prospective purchaser.

Great Service, quick response
Nicholson Heating Services were recommended to me by Worcester Bosch, makers of my boiler. I needed a reputable company to service my boiler to keep it in warranty. The service was arranged quickly and done to high standard, to keep my boiler running at its optimum performance. The service charge was far cheaper than Worcester Bosch would have charged. I cannot recommend enough.

A great company both local and reliable. Always arrive on time and carry out work with minimal mess and disruption. New Boiler installed and serviced by them on an ongoing service contract (much cheaper than other big names). All the staff from the reception to the engineers are helpful and pleasant to deal with. Very happy.
