The service
New installations and repairs, same standard
Whether it's a brand-new circuit, a consumer unit upgrade, or putting right a fault that's been building for months, installations and repairs are the bulk of the day-to-day work at Linehan Mechanical & Electrical Ltd, trading as Linehan Electrical. Gary Linehan has been in the trade for 20 years, based in Stevenage and working across Hertfordshire, Bedfordshire, Cambridgeshire and London.
Installations cover anything from a single socket or light fitting to a full rewire, a new consumer unit, outdoor lighting or an EV charger. Repairs cover fault finding and fixing: tripping circuits, dead sockets, flickering lights, or issues flagged by an EICR.
The business is an NICEIC Approved Contractor, independently assessed against the national standard for electrical contractors, and carries £10m public liability and £10m employers' liability insurance. Clients range from homeowners to commercial and domestic clients needing larger-scale work.
Every installation or repair starts with a free quote, from photos for smaller jobs, from a site visit for anything bigger, and ends with testing, certification where required, and a 12-month guarantee on the workmanship.
If it's left
Common reasons people call for an installation or repair
Some jobs are planned: a new kitchen, an EV charger. Others are reactive: something's stopped working or started behaving oddly. Both get the same approach.
Recurring faults
A socket or circuit that fails repeatedly usually has an underlying cause that a quick fix won't solve | it needs proper fault finding.
Half-finished installations
Fittings installed without proper testing or certification can be unsafe even if they appear to work.
Old wiring behind new finishes
Renovated properties sometimes hide old or unsafe wiring behind new plaster and flooring, found only once work starts.
DIY installs
New sockets, switches or lighting fitted without the right qualifications is a common cause of later failures and can fail an inspection.
Overloaded or under-specified circuits
New appliances or EV chargers added to an existing circuit without checking capacity can cause tripping or overheating.
Delayed repairs
Putting off a known fault | a warm socket, a flickering light | risks it becoming a bigger, more disruptive job later.
Common mistakes we see
- ×Living with a recurring fault instead of getting it diagnosed properly
- ×Letting unqualified labour fit new sockets or lighting
- ×Adding an EV charger or appliance without checking circuit capacity
- ×Ignoring findings from an EICR
- ×Assuming a flickering light is minor and leaving it
- ×Ignoring a burning smell or warm faceplate

Tell us the job
Call or send photos describing the fault or the installation you need. Small jobs are usually quoted from photos; bigger jobs get a free site visit.

In detail
What installations and repairs cover
This is a broad category spanning new work and fixes. Here's the detail on materials, methods and the kinds of jobs involved.
Materials and equipment
New installations use standard twin-and-earth or flexible cable depending on the circuit, with modern RCD and RCBO-protected consumer units and accessories to match the property. Repairs use like-for-like or upgraded components depending on what's found on inspection.
Where equipment such as extractor fans or consumer units is fitted, manufacturer warranties vary: for example Vent-Axia fans may carry up to a 7-year manufacturer warranty, and Hager fuseboards may carry 1 year. These sit alongside, not instead of, the 12-month workmanship guarantee.
Methods and standards
All installation and repair work is carried out to BS 7671, the UK wiring regulations, and notified under Part P of the Building Regulations where required. Fault finding follows a logical sequence, isolating circuits, testing continuity and insulation resistance, and checking RCD operation, rather than trial and error.
Repairs on older installations sometimes reveal wiring or connections that no longer meet current standards; any such findings are flagged and quoted before further work proceeds.
Common job types and variations
Installations: new sockets and circuits, lighting and outdoor lighting, consumer unit upgrades, EV chargers, and full or partial rewires. Repairs: tripping breakers, dead circuits, flickering lights, damaged accessories, and putting right issues found on an EICR or during a house move.
Small jobs are usually a single visit. Larger installations, like a rewire or a new distribution board, are scoped properly during the quote since the time needed depends on the size and condition of the property.
Residential versus commercial situations
In homes, installations and repairs are usually about day-to-day safety and comfort: a new light, a fixed fault, a safer fuseboard. In commercial and industrial settings, the same categories apply at a larger scale: new circuits for equipment, lighting for a working space, or fault finding on a larger distribution system.
Commercial jobs typically need a site visit before quoting, since access, existing infrastructure and the scale of the fix vary far more than in a typical home.
Access, timing and tidiness
Repairs are often completed in a single visit once the fault is found. Installations that involve chasing walls or lifting floors take longer and mean more disruption, but the aim is always to leave the site clean and tidy at the end of each working day, not just at the end of the job.
Where extra work is uncovered once a wall or floor is opened, common in older properties, it's quoted and agreed with you before it goes ahead.
