“Arrived 45 mins later which was past 10 on a Saturday night. He diagnosed the problem, replaced switches and sorted burnt wiring.” — Paul Silvester, via Google

What Bestfix does.
Electrical work and plumbing and heating from the same engineer — which is why a fault that sits between the two doesn't need two appointments.

The engineer who turns up when it's gone dark and the water's still rising.
Bestfix is a small Guildford firm built around one person: Balazs, an electrician who also works as a plumbing and heating engineer. That combination is unusual and it's the whole point — a tripping circuit behind a boiler, a leaking radiator valve on a live floor, an immersion heater that's cooked its wiring. Those jobs normally need two trades and two waits. Here they need one visit.
The work is ordinary domestic and commercial stuff done properly: consumer units and fault finding, EICRs and safety testing, leaks, drips and pipework, boiler repairs and servicing, moving and replacing radiators, gas safety inspections, and smart-home lighting and CCTV when you want the house to do a bit more thinking. Bestfix describes itself as NICEIC-approved and Gas Safe registered.
Electrics and water, same engineer
Most jobs that start as "the boiler's playing up" turn out to be half electrical. Balazs covers both trades, so there's no second call-out and no two firms blaming each other.
Out of hours means out of hours
Bestfix advertises cover Monday to Sunday, 24 hours, 365 days a year — and the reviews back it up: one customer had a switch and burnt wiring sorted after 10pm on a Saturday.
The same face every time
Companies House lists one director, and every Google review names the same engineer. You get Balazs on the phone and Balazs at the door.
Certificates, not promises
EICRs, EICs, EPCs and gas safety inspections — the paperwork landlords, buyers and insurers actually ask for, issued after the work, in plain English.

Consumer unit, wired and labelled
A modern board with RCBO protection on every way, cabling dressed into the trunking and each circuit labelled — the difference between a fuse box you're afraid of and one you can safely switch off yourself.

Under-sink pipework and water heater
Flexible hoses, isolation valves and a point-of-use water heater plumbed in behind a kitchen sink. Isolators fitted where you can actually reach them, so the next repair doesn't start with turning the whole house off.

Burnt main switch, found and replaced
Heat damage and scorching around an old main switch — the kind of fault that hides behind a cover until something trips for good. Found during fault finding, isolated and replaced.

Testing at the board, not guessing
Insulation resistance and continuity measured circuit by circuit with a multifunction tester. It's the slow part of the job and it's the part that turns an opinion about an installation into a certificate.
Worth reading before you need it.

03“Balazs very kindly came out for an out of hours call. He was very knowledgeable, could fix the electrical issue affecting my boiler very confidently”
04“The plumber that came out was an absolute delight. Very polite and helpful. He fixed the problem and advised me on further action that will be needed”
How a Bestfix job runs.
01
Call, any hour
One number, answered by the person who'll be doing the work. Describe what's happening — the noise, the smell, the trip switch that won't stay up — and you'll get a straight answer about whether it's an emergency or something that can wait until morning.
02
Diagnose before quoting
The cause gets traced before anything is replaced. Reviewers describe exactly this: the problem diagnosed, then the switches and burnt wiring dealt with. No parts fitted on a guess, and no work starting before you know what it involves.
03
Fixed, tested, written up
Work is tested before it's signed off, and where a certificate applies — an EICR, an installation certificate, a gas safety record — you're handed it with the faults and recommendations explained rather than buried in codes.
