Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 26 years on the register also points to an established business rather than a brand-new one.

Customer recommends this business
Victorian house building and renovation project
Paul and the team worked fantastically on our Victorian family home project. It required a great amount of structural work, renovation, full electricity rewire and plumbing. The project finished on time and with fantastic results. Paul was always available to discuss the project and keeping us inform at all stages. I have no hesitation in recommending him.

Customer recommends this business
Great work
In 2019, Complete Construction carried out a ground floor extension for us and work on the upstairs bedroom. We were extremely pleased with the work done, which was carried out to a very high standard. Complete Construction were efficient, reliable, tidy and the quality of the work was excellent. I am very happy to recommend them.

Overall very happy
We had a loft conversion built last year and was very happy with the overall quality of the work done and the way they adapted to our changes half way through. suggestions were made and weren't pushed into any of them. I advise using this company for integral work and i'm sure for other types of projects
Extremely Pleased
Last summer (2013) Complete designed and installed a new kitchen in our house. This also involved removing internal walls and replacing with steel beams Was done with the minimum of fuss and in a very professional manner. All staff on site were polite and did their best to keep disruption and mess to a minimum The standard of work was excellent and above all Paul was easy to talk to and very open which ensured things ran smoothly and remained in budget Great job and happy to recommend!
Exceeded all expectations
I had a loft conversion and internal building works carried out by Complete Construction in Jan to March 2014. They worked with me to finalise my plans suggesting improvements and nothing was too much trouble. During construction the tradesmen were polite, tidy and highly skilled. Given I lived in the house during work they worked hard to minimise impact & always left the site tidy each day. I am absolutely delighted with the work that exceeded all expectations, would highly recommend this firm.

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.
