Excellent 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.

Consummate professional 👌
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.

Great work
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.

Installation of new boiler
A great experience using Darran Grant LTD. Everything was explained clearly before the work was carried out and I received regular contact from the office regarding dates/times etc. During the installation the tradesman was extremely professional,and the work was carried out to a very high standard.All rubbish was taken away and my home was left clean & tidy. He explained everything as work progressed and informed me about aftercare,servicing etc.

No reponse to enquiry
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.

Excellent Service Provided
I had an issue with 4 of my radiators not getting hot. A powerflush did not resolve the issue. However Billy the engineer from Darran Grant Ltd identified the problems. This was not an easy job as it required gaining access to the pipes below the floorboards to try and locate where the blockages were. He resolved all the issues and was very respectful of the property and ensured everything was back to the way it was before he started. I would highly recommend their services.

Great work
I needed a new boiler due to my old system causing me a lot of issues so contacted Darran for a quote. From initial contact to completion of work I was really pleased. I was spoken to about the options I had and opted to switch my heating system to a combi boiler. Darran booked me in for a time that was suitable for me. When work started both Darran and Billy were very professional. Both really friendly as well. Work completed to a very high standard and I am really pleased with the completion of the work. I will not hesitate to have them back for boiler servicing etc.

Thoroughly professional boiler replacement.
Cannot speak highly enough about Darran Grant Ltd. We needed to replace our old combi boiler which was 14 years old with a new boiler and have cast iron stack/vent pipe removed and replaced with new plastic pipe. Also, 2 rads were replaced. When Darran came to view the job. We discussed what was required, also the performance of our heating system to the kitchen and bathroom After consultation, it was suggested that the pipes around the system to this area were too narrow (8mm) for the heating system. He needed to upgrade the pipes in this area with 15mm. I asked Darren to replace the radiators in the bathroom and kitchen. Before recommending a boiler to meet our needs Darran checked the cold water flow rate. We agreed on a start date and work commenced on the Tues16th of May A few days before the start day Emma contacted me and confirmed that Darran would be with us on the date agreed. Darran arrived on the date and time agreed with his employee Billy and didn’t waste any time getting started. Both Darran and Billy were very conscientious, nothing was too much trouble they were a delight to work with. The work was finished to our complete satisfaction with no mess at all and our heating system working perfectly. I Would highly recommend using Darran Grant Ltd Darran and Billy were excellent workers professional and friendly. I would like to say that the service provided by Emma in the office was also excellent, Truly professional service all round

Excellent work, clean and on schedule.
We first contacted Darren Grant last October to discuss reasons for inadequate performance of our heating system, ( radiators not getting warmer than Luke warm). After consultation it was suggested that all the pipes around the system were too narrow (8mm) for the heating system. He needed to upgrade all the pipes throughout the house with 15mm. Also, as our boiler was probably approximately 10 years old it was suggested that it be replaced with a brand new Worcester Boiler. However, as Darren was so very busy he was very honest in telling us he wouldn’t be able to commence work for a number of months. We were prepared to wait. Work commenced on the 24th of April 2023 and was estimated to take about a week to complete. At 8am on that day, Darren arrived with his employee Billy and didn’t waste any time getting started. Bang on target, the work was completed on Friday 28th. The work was finished to our complete satisfaction with no mess at all and our heating system working perfectly. All our new carpets which had to be taken up in every room were relayed and you wouldn’t have known they’d been there in the first place. A wonderful job, two exceptionally nice people.

Darran Grant Ltd (accredited Worcester Bosch heating engineers) installed a new Worcester Bosch oil boiler to replace my old one. The whole process was a seamless exercise from when I received their quote to when the work was completed. I was very fortunate to find Darran Grant Ltd. - professional, efficient, polite, tidy, an eye for detail and time also whilst on site to explain matters to me. In a nutshell, a faultless exercise.

Professional and reliable
Darran and Billy were excellent! Truly professional service. They managed to effectively fix our heating system without ripping up all the floorboards or knocking holes in the walls (as other engineers had suggested would be required to determine the problem!). Thank you both so much for doing such a good job! It’s refreshing to have had such reliable, honest, efficient, neat workmen complete the job and finally have a heating system that works again.

Excellent! Professional! Highly recommend
We contacted Darran for a replacement boiler as a neighbour of ours recently used the company for similar work. From the moment Darran arrived we knew we were in safe, honest, capable professional hands. Appropriate advice was given when needed, he is clearly very passionate and knowledgable in this area. The whole service before the work began was excellent and when it came to installation day this was great too. The team did long days, worked hard, kept the house clean and tidy! Can’t recommend this team enough! Thanks

A great team
Darran and his team carried out work over 3 days to replace our oil boiler. From start to finish from our initial contact through to the finished job we couldn’t have been happier with the service we received. All 3 engineers who attended for the installation were professional, courteous and kind. 5* service yet again received from Darran Grant Ltd.

New combi boiler
Great support and advice to ensure that I had the replacement boiler that would work best for my type of property. Not pushy, just honest advice. The team removed the old storage tank and traditional boiler to replace with a Worcester boiler. No mess, friendly guys, perfect service. So glad that I decided not to use British Gas, and had Darran Grant Ltd install instead at a more competitive price.

I found Darran Grant Ltd online while looking for a company to service my Calor Gas boiler. After reading many positive reviews, I went ahead and contacted the company. Everything since then has been flawless. Communication has been excellent and the works carried out have been to the highest standard. Everyone from the office to Darran and colleagues on site have shown that customer care is paramount. I have no hesitation in recommending this company to anyone.

Boiler upgrade
I was looking to upgrade my 16year old combi boiler with the added complication of the solar hot water. I used Darran Grant Ltd, a truly professional team that delivered what they said they would, in the timescale agreed. They demonstrated outstanding attention to detail and kept me informed from the very beginning to the end of the process. On completion of the boiler installation they left the work area clean, tidy and took all of the rubbish away with them. An absolute pleasure to work with and I would not hesitate to recommend Darran and his team (Billy and Joe) to anyone.

Very neat heating system installation
I approached Darren Grant Ltd to install a replacement boiler and pressurised hot water system in my home. My old system relied on a pump to supply a good flow to the domestic hot water system in the house. Since there are two showers in the property, the pump was able to maintain the flow. The downside was the noise from the pump, especially when using DHW at night. Darren installed a Worcester Bosh Green Storage cylinder to replace the old tank in the airing cupboard. A Worcester Bosch 8000 gas boiler installed in the loft space provided the heart of the system. A new pipe supply from the water main throughout the property and a larger gas supply from the meter to the boiler made the installation a bit more challenging. The work was carried out over a 5 day period and was done with the minimum of disruption and any mess was kept to the minimum. The pipework is exceptionally neat and tidy. The new system is very quiet and the two showers feel like power showers. The house is warm and comfortable. All the work is covered by Worcester Bosch 12 year guarantee. I have no hesitation in recommending Darren Grant Ltd.

Heat Pump Installation
Having used Darran Grant`s services previously, I was confident that he would carry out the work to my entire satisfaction and I was not disappointed. He arrived in good time on the date specified and was able to carry out all the work without disturbing my day in any way. Everything now works well and I would heartily recommend his services and professional approach to anyone wanting to use his many plumbing and heating skills. I feel lucky to have found him some three years ago.
