Hennessy have completed three projects for the school I maintain. Each time they have demonstrated a commitment to deliver what was asked of them without compromising the safeguarding of the pupils and staff. With short notice they have met deadlines due to their expertise and willingness to go the extra mile.

Hennessy are a family run company who are easy to communicate with and keep you informed of every step of the process. They are very honest and give the best advice. I cannot fault Thomas and Merrik’s work and would highly recommend Hennessy’s to anyone.

Just had my patio relay with new patio tiles both ends of the garden. They have done a great job . The guys laying the patio were great. If you asked them to change something because you did not like it no problem. They kept you informed on what they were doing so you could look and if you wanted it change they just change it for you. I have used hennessy before always a top job . And then Breandan the main man inspects the job . You only pay when when he thinks the job is done to his standard. 10 out of 10 I well be using them again.

I've used Hennessy LTD builders multiple times. First time was for renovating a newly bought house, including structural repair/improvements. I chose them because they seemed the most trustworthy, and indeed they were: the house condition was worse than initially thought, but they dealt with everything impeccably: fair pricing, and quality made to last. I used them a few times since: to repave my front porch, and repair weathered chimneys stacks.

I had a very positive experience with them. The team was professional, knowledgeable, and responsive throughout the entire process. Communication was clear, deadlines were met, and the quality of work exceeded expectations. They demonstrated a strong commitment to customer satisfaction and were always willing to answer questions and provide helpful guidance. I would happily recommend Hennessey Ltd to anyone looking for a reliable and trustworthy company, and I look forward to working with them again in the future

I had several jobs done by Hennessy Ltd, my biggest job to date with Hennessy was a kitchen Extension, work was done to perfection, builders was very polite and left my house clean. I would recommend this company to friends and families and anyone who is looking for a good builder, they are easy to get hold of and their work is 100% guaranteed.

Callum

Honestly didn’t know where to start when it came to getting a rear extension done, but, a mate pointed me toward Hennessy LTD and I’m dead happy he did. What sold it for me was how straightforward they made the whole thing. Plans, building control, all the building works, they handled the lot. No juggling different trades, no stressing about project managing it myself. Just one team getting on with the job. Callum and Brendan were sound throughout. Always straight with you, happy to answer any questions and you could tell they actually cared about getting it right rather than just getting it done. The whole job came in at a fair price and was finished when they said it would be, which, let’s be honest, isn’t always a given with building work! They also brought in AffixWindows for the windows and rear door on the extension, and the fact that the two companies worked together so seamlessly meant I didn’t have to get involved in coordinating anything. Brilliant from start to finish, I’d recommend Hennessy LTD to anyone without a second thought.

Megan Bostridge

Hennessy LTD recently refurbished our home, fitting a brand new kitchen and bathroom in the process. We also had our windows replaced through their sister company, AffixWindows, a great shout if you’re looking to get multiple jobs done at once. Everything was completed on time and the quality of the work speaks for itself. The whole team were a pleasure to deal with, friendly, approachable, and always happy to help. What really stood out for me was the honesty shown during the quoting stage. Rather than trying to upsell, Callum and Brendan took the time to walk me through alternative options that would actually save me money. That kind of integrity is rare and really appreciated. I wouldn’t hesitate to recommend them!

Connor Butler

I used Hennessy Ltd to replace our kitchen and they did a fantastic job. Would absolutely use them again. Callum and Brendan were really helpful during the entire process. We had Mark install the kitchen who was great. He kept things as neat and tidy as he could throughout and his attention to detail was fantastic.
