Highlights

"Billy and his team have just completed a single storey rear extension on my house. This is the first time I have ever done such a major renovation and I was very nervous about the whole process. Billy has been very patient with me, explaining everything that needed to happen and keeping me updated throughout. Any problems (of which there weren't many) he sorted out straightaway, including a couple of changes to the original design as the build progressed. His team work incredibly hard and I could not be happier with the end result. I would not hesitate to recommend Billy and his team."

"The newstock team carried out a massive refurbishment on my bungalow including the demolition only leaving 2 walls standing. Refurbishment included foundation drainage and building the full shell to watertight this was all carried out in great time considering the bad rain we have had the last few month. Thanks Newstock Develoments."

"Standard of work is exceptional. Billy is extremely engaged the whole way through the process. Site was tidied every eve before they left. All hurdles were discussed and handled by Billy. One stop shop, everything handled from plumbing and electrics to roofing. Would highly recommend."

Smart checks

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?
