Our story

A small outfit, on purpose

JMO Electrical Services is a NAPIT-registered, Part P-registered electrical contractor based in Purley, Surrey, serving domestic and commercial customers across Croydon and the surrounding area. Run by Jonathan Oatley with fifteen years' experience, it is a small, hands-on outfit, Jon plus one apprentice, offering personal service rather than a call-centre experience.

Who we help: homeowners who want work done properly and explained in plain English, landlords and agents who need certificates on time, and small businesses that cannot afford to lose trading hours to an electrical problem.

What we specialise in: rewires and partial rewires, consumer unit upgrades, fault finding, EICRs and landlord certificates, EV charge points, outbuilding supplies, lighting, commercial wiring and 24/7 emergency call-outs.

Where we work: Purley and the CR postcodes, Croydon, Caterham, Merstham, Redhill, Reigate, Dorking, the wider Surrey area and south London, close enough that a return visit is never a problem.

That means the electrician who quotes your job is the electrician who turns up to do it, and the one who signs the certificate at the end. Nothing gets passed down a chain of subcontractors.

All work is covered by £2 million public liability insurance and backed by a one-year workmanship guarantee, with free quotes on planned jobs. Standard hours are 8:00am–5:30pm, with emergency call-outs available evenings, weekends and 24/7.

Mission and standards

How we work, and what you can hold us to

The aim is simple: leave every installation safer than we found it, and leave every customer clear about what was done and why.

Work to BS 7671, every time

Every circuit is installed and tested to the IET Wiring Regulations, whether it is one socket or a full rewire. There is no 'good enough for a small job' standard here.

Certified and notified

NAPIT registered and Part P registered, so domestic work is certified and notified to Building Regulations on your behalf rather than left for you to sort out.

Priced before it starts

Free written quotes on planned work. If something unexpected is found behind a wall, you hear about it and agree it before any extra work happens.

The same face throughout

The person who quotes your job is the person who does it and signs the certificate. Nothing is passed down a chain of subcontractors.

Guaranteed for twelve months

All workmanship carries a one year guarantee, backed by £2 million public liability insurance on every job.

Honest about scope

If a job is not something we do, we say so straight away instead of taking it on and learning on your property.
