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.

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.

Cannot speak highly enough about this man. Very conscientious, nothing was too much trouble he was a delight to work with, as was his mate billy. Just for the record he installed a complete heating system for me. Would highly recommend him. He knows his stuff……….

The boiler and fire also boiler heating the water behind fire. All done neatly and thoroughly far better than previous gas fitters. I intend that they bring my heating system up to date next year.

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.

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.

Had my boiler repaired 4 months ago by Darran, who came recommended to me. He did a fantastic job and did so quickly and efficiently, as well as being friendly. Spot on job - would definitely recommend to others.

I had 2 Japanese toilets with cabinets made - Darran's team were reliable in that they turned up when they promised, left the place clean and tidy and also removed all the rubbish which was a god send.
