What Our Customers Say

Real feedback from clients across London and surrounding areas

★★★★☆

Good service overall. The rewiring took a day longer than expected, but the quality was solid and they tidied up properly.

SE
Sarah Edwards
Clapham, London
★★★★★

Needed six new sockets installed in our converted loft. The electrician was punctual, worked efficiently, and finished in half a day. Price matched the estimate exactly. Professional job from start to finish.

TP
Thomas Phillips
Balham, London
★★★★★

We run a small café and had persistent issues with our kitchen electrics tripping. Previous contractors couldn't find the fault. Davaku sent someone who spent two hours methodically checking every connection. Turned out to be a worn cable behind the dishwasher. They replaced the section, tested everything twice, and gave us a written safety report. Haven't had a single problem since. The cost was reasonable considering the time they spent diagnosing it properly.

AR

Tooting, London
★★★☆☆

Decent work on our outdoor lighting. The electrician knew what he was doing, and the lights work perfectly. Communication could have been better - had to chase them twice for updates. Price was competitive though.

MH
Michael Hughes
Streatham, London
★★★★★

Fast response, fair pricing, clean work. Installed our EV charger in three hours. Would use again.

DW
David Wilson
Battersea, London
★★★★☆

Had our entire flat rewired during renovation. The team was skilled and respectful of our property. They covered everything with dust sheets and hoovered daily. Only minor issue was they arrived 30 minutes late one morning, but they stayed late to make up the time. Final inspection passed first time.

LC
Lucy Carter
Wimbledon, London
★★★★★

Emergency call at 7pm when our fuse box started smoking. Davaku had someone at our door within the hour. He isolated the fault, made it safe, and returned next morning with replacement parts. Explained the cause was an overloaded circuit from our old tumble dryer. Upgraded the circuit to handle modern appliances and tested everything thoroughly. The emergency callout fee was clearly stated upfront, and the follow-up work was invoiced separately with no surprises. Felt genuinely cared for during a stressful situation.

★★★★★

Straightforward socket replacement and safety check. The electrician spotted a loose connection in another room and fixed it at no extra charge. Appreciated the honesty and attention to detail.

Earlsfield, London
★★★★☆

Reliable service. Installed new lighting in our office. Work was completed on schedule. Would have preferred a bit more flexibility with appointment times.

PT
Peter Thompson
Clapham Junction, London
★★★★★

Needed our Victorian house brought up to current safety standards before selling. Davaku provided a detailed quote breaking down every item. The work took three days, and they coordinated perfectly with our building inspector. All certificates provided immediately. The buyer's surveyor found zero electrical issues. Worth every penny for the peace of mind.

GS
George Sullivan
Dulwich, London
★★★☆☆

Mixed experience. The actual electrical work was fine - installed new consumer unit and tested everything properly. The electrician was knowledgeable and answered all my questions. However, they were two hours late on the first day without calling ahead, and I had to request the completion certificate twice before receiving it. For the price point, I expected smoother service. The end result meets regulations, which is what matters most, but the process could have been better managed.

KM
Karen Mitchell
Brixton, London
★★★★★

Excellent value for money. Replaced all our downlights with LEDs. Saved £80 compared to other quotes and the work was impeccable.

NH
Neil Harrison
Mitcham, London
★★★★★

Our landlord hired them to fix recurring problems with our heating controls. The electrician traced the issue to incorrect wiring from a previous job. He rewired the thermostat properly and showed us how to use the timer functions. First winter in three years where the heating works as it should. Professional and patient with our questions.

OA
Olivia Anderson
Colliers Wood, London
★★★★☆

Solid work on our garden electrics. Installed weatherproof sockets and lighting for our summer house. The cable routing was neat and they explained the IP ratings clearly. Minor delay getting the parts, but they kept me informed. Happy with the outcome and the price was fair for the materials used.

★★★★★

Quick turnaround on our kitchen socket upgrade. Clean installation, tested everything, left no mess. Exactly what we needed.
