Whole packages, design to handover.
For main contractors and developers we carry the complete electrical package: initial design, installation, testing and the handover file. Fewer interfaces on your programme, and one name responsible for all of it.
What contractors say.
We would have no hesitation in recommending them to other contractors and clients looking for a professional, reliable and quality-focused electrical contractor.
Crest have consistently supplied the necessary labour and resources to ensure works are completed within the required programme, while also responding effectively to additional works and changes that arise during a project.
Communication is a particular strength of Crest. They maintain regular contact with both our site and office teams, ensuring that priorities, programme requirements and any issues are understood and dealt with promptly.
Where design information has not been provided by the relevant design teams, Crest have also been proactive in developing practical solutions and designing elements of the works to keep the project moving.
Recent commercial work.
Dealerships, a full school refurbishment and a complete block of flats.
Asked by businesses.
Can you work around our trading hours?
Yes. Testing, upgrades and fit-out phases are planned around opening hours and programme dates. Out-of-hours work is normal for us, not a favour.
Do you take on maintenance as well as installs?
Yes. We run planned and reactive maintenance contracts for premises we look after, which means call outs are handled by a team that already knows your building.
What size of contract suits you?
From additional works within someone else’s programme up to complete whole packages of £500k and up. Big enough to deliver, small enough that the person quoting is the person responsible.
Who would manage our account?
The owner of the firm. Dealing with the person who can actually make a call on the spot is a deliberate part of how Crest works.
