Highlights
“Luke delivered a brilliant loft conversion, completing the project with remarkable speed and efficiency. His clear communication kept me informed at every step, eliminating any surprises. The craftsmanship was of great quality and perfectly transforming my space as planned. His honesty about pricing and timescales was refreshing and built complete trust. I’d recommend Luke for any future projects.”
“Extremely happy with the full house renovation carried out. Dealt with Luke who was extremely helpful throughout the whole process keeping me updated with what was going on. Works were carried out to a top standard and finished earlier than expected which is always a bonus. Would highly recommend if you're looking for someone who is reliable and actually delivers. Thank you LLOCK Building for making this an easy and enjoyable process considering the big changes that were made.”

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever 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.
