Highlights

"We’re absolutely delighted with our loft conversion, which included a small bedroom and a large ensuite. The workmanship was excellent, the project was completed on time, and everything was well organised. Communication was great throughout, and the job finished with a professional clean-up. We would highly recommend their services."

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.
Want an extra legitimacy check?
