Highlights
"Jamie and his team completed our loft extension and we couldn’t be happier with the end result. This is the second project that Jamie has done for us and we didn’t hesitate asking Jamie back. The attention to detail was perfect and Jamie helped make suggestions to maximise the space. Everyone Jamie worked with was knowledgeable and completed the work to a high standard."
"From start to finish, Jamie and his team made the whole building process enjoyable. It was a large project with limited time to have it ready for Christmas. However, even with the added pressure of limited time, we were kept up to date with progress throughout the whole project. Everyone on the project went out of their way to keep us informed and treated the build like it was their own. Quality of their service was second to none. Always on time, courteous and always polite and considerate to our neighbours. I would always recommend JRT Group to anyone! Thank you - It’s amazing!"
"We cannot recommend Jamie and Liam highly enough. They have built us a great extension and did so on time and to budget. They are also very friendly and professional, so we would have no hesitation in using them again or recommending them to others. Thanks for all your hard work, guys!"

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
