Heating system replacement

We recently had our house heating system replaced by Darren Grant Heating and Plumbing, and we couldn’t be happier with the service provided. From start to finish, the team was professional, punctual, and extremely knowledgeable. They took the time to explain every step of the process, answering all of our questions clearly and making sure we fully understood how the new system works. Their advice was honest and helpful, which gave us real confidence in the decisions we were making. The installation itself was carried out to a very high standard. They worked efficiently, kept everything clean and tidy throughout, and left our home spotless once the job was complete. It’s rare to find a company that combines quality workmanship with such great customer service. I would highly recommend Darren Grant Heating and Plumbing to anyone looking for reliable, skilled, and trustworthy heating engineers.

Excellent boiler installation work carried out by Darran Grant Ltd

I first contacted the company seeking a quote for the installation of a new Worchester Boch boiler as my old BIASI boiler had ceased working and I was living without heating. Darran arranged to visit my home the very next day (Tue 3rd Feb) to investigate the work that would be involved and to discuss with me the various options available. Having determined my requirements, and scoped out the necessary work, Darran explained to me what work would need to be carried out and included in the detailed quote he would prepare for me. The quote, requiring two days of installation work, was emailed to me the following day (Wed 4th Feb) and having considered it in some detail I also accepted it later that day. In view of the fact that I was without heating, Darran would arrange to carry out the work ASAP and agreed to start the work on the following Monday. . Darran and Harry arrived at 8am on Monday (9th Feb) to start the work and, as promised, completed it on Tue 10th Feb. Everything was done to keep my house clean and tidy throughout the work. Upon completion everything was restored to as it had been previously and you would hardly have known they had even been there. Upon completion the timers and controls of the new system were explained thoroughly to me. Praise also for the office manager, Emma, who was in constant email contact with me providing the necessary information and paperwork. I can certainly recommend Darran Grant Ltd for all your boiler and associated heating work.

I am thrilled with my new Worcester Bosch boiler. Darran and Harry of Darran Grant Limited worked efficiently, respectfully, and all was left tidy when finished. I would have no qualms about recommending them.

It was a pleasure to deal with Darran from the first visit to identify the problem with my under floor heating to his return to rectify the problem. Everything was well organised and the communication was first class and the job was completed professionally, efficiently and on time with everything cleaned up at the end of the job. Darren took the time to explain everything before he left and I’m confident that if there are any issues when we turn the system on when required that Darran will be on hand to sort it out which is very reassuring. First class 👍

New Worcester Bosch Boiler

We had a new boiler installed plus new radiator valves and a Hive thermostat. The job was done within the time quoted, and on budjet. Darran is the cleanest workman I have ever experienced, he cleaned up as he went along leaving very little dust. He was able to overcome a couple of unforseen situations without any trouble or extra cost. He is a very personable man and can be trusted to be left alone in the house to carry on with the job, Highly recommended.

We had an old solid fuel system removed completely and a new gas central heating installation carried out by Darran (and Billy). All old system removed and disposed of, then 7 radiators, combi boiler and every piece of pipework replaced with new. Darran said the work would take five days but he managed to complete the installation in just four with just the commissioning required on the fifth day. There were a few challenges along the way but all were overcome with a smile and never a cursed word. At the end of each day all the rubbish was removed and the house left spotlessly clean. At the end of the installation Darran then took the time (and patience) to run through how the controller worked and also told me that if there were any problems with my programming the system I was to give him a call and he would resolve them. I cannot recommend Darran highly enough. A pleasure to have him carry out the work for us. Polite, Clean, prompt and cheerful. What more could you want.

He explained everything as work progressed and informed me about aftercare,servicing etc.

I contacted Darren Grant on 07/02/2024. Spoke with someone, gave details of the work needed. The person then said they would speak with the manager about the job and call me back. She confirmed the number to call me back on, then never returned the call.
