It's one of the most common questions we get asked, and it's a fair one. Socket replacement is bread-and-butter electrical work — not complicated, not scary, just a job that needs doing properly by someone qualified. So let's talk about what it actually costs and, more importantly, what affects the price.
Replacing a double socket outlet — a standard white plastic double socket in a straightforward location — starts from £98.48 + VAT with Bright Spark.
That price covers labour, the socket itself, isolation of the circuit, testing, and making good. It assumes the job is clean and uncomplicated: the wiring behind the socket is in good condition, the back box is sound, and we're doing a like-for-like swap. One socket out, one socket in.
For most routine replacements in a modern or recently rewired home, that's exactly what happens.
Here's where it's worth being straight with you, because the starting price isn't always the finishing price — and there are legitimate reasons for that.
The condition of the wiring behind the socket. In older properties, what's hidden behind the faceplate can be a surprise. Wiring from the 1970s and 80s often has rubber insulation that's gone brittle and crumbly over time. When that's the case, we can't simply swap the socket and walk away — because the connection point itself isn't safe. We'll tell you what we've found, show you if we can, and give you options. That might mean a small cable repair, or it might point towards a broader conversation about the installation. Either way, you'll know before anything proceeds.
No earth conductor. Some older wiring doesn't include an earth wire at all. That's a specific situation that needs handling correctly and can't just be ignored when fitting a replacement socket.
The type of socket you want. Standard white plastic is the entry-level price point. If you're upgrading to a brushed steel, chrome, or satin nickel finish — which a lot of people are doing during renovations — the socket itself costs more, and that's reflected in the final price. USB sockets with built-in charging ports (particularly USB-C, which is where most devices are now) are also more expensive than a standard outlet, but the price difference is modest for the convenience they offer.
Single to double upgrades. If you've got a single socket and want to replace it with a double, that usually means changing the back box — the housing set into or mounted on the wall. If it's surface-mounted, that's straightforward. If it's flush-fitted into the plaster, the wall may need a small amount of chasing to accommodate the wider box. Not a big job, but it adds a little time.
Multiple sockets in one visit. One thing worth knowing: if you've got several sockets to replace, booking them together in a single visit is the most cost-effective way to do it. Travel time and the minimum charge are spread across the whole job rather than repeated for each socket. If you're replacing one socket now and thinking you'll probably do three more at some point, it's almost always worth doing them together.
We get asked this too, so it's worth being clear. The price includes:
The socket outlet itself (standard white plastic at the from price), labour to safely isolate the circuit, remove the old socket, check the wiring, connect and fit the new socket, test the circuit and confirm everything's working correctly. You also get a full digital invoice that details the work carried out, time, and a breakdown of labour and materials. Hard copies are available if you'd prefer one.
We don't cut corners on testing. Every socket we fit is tested before we leave.
As mentioned above, white plastic is the baseline. If you want something different, we're happy to accommodate that — we just need to know in advance so we can bring the right materials.
Brushed steel and chrome finishes are the most popular alternatives right now, particularly in kitchens and living rooms. USB sockets are increasingly common in bedrooms and home offices. If you're not sure which to go for, have a look at what's already in the room — or ask us. We can advise on what works well and what's available.
One thing to be aware of with USB sockets: the USB-A ports that were standard for years are being phased out as devices move to USB-C. If you're fitting new sockets, it's worth specifying USB-C or a combined A/C socket rather than USB-A only, so you're not fitting something that's already outdated.
You can, but there are a couple of things to understand if you go down that route. We won't provide a warranty on parts we haven't supplied — if the socket fails, the cost of returning to replace it is down to you. We also can't guarantee the quality or suitability of parts we haven't sourced ourselves. For a cheap socket from a DIY shop, the risk is yours. Our preference is always to supply the parts ourselves — we charge trade price plus a standard markup to cover admin and transport, and the parts are right for the job.
It's electrical work. It seems simple — and in experienced hands it is — but socket replacement involves working on a live electrical installation, and the consequences of getting it wrong range from a non-functioning socket to a fire risk. In the UK, electrical work must meet BS7671 (the wiring regulations), and the work needs to be carried out competently. An NICEIC registered electrician, like everyone on our team, is the right person for the job.
It also matters when you come to sell your home. Buyers' solicitors ask about electrical work. Work that's been done without certification, or done poorly, can hold up a sale or cause problems with buildings insurance.

My external security lights had failed and because they were over 20 years old, several electricians felt unable to help me. I then asked Karen from Bright Sparks to get involved. She promptly surveyed the problem, gave me a competitive quote and as soon as I accepted it, gave me a firm date for the work to be undertaken. Her electricians arrived on the due date, were very friendly and tidy and worked in difficult places without problem. I definitely intend to use Bright Sparks again.
We found the service to be friendly and pro-active. We had an appointment quickly and the engineer was able to find the issue, which was not straightforward, within an hour and rewire the effected ceiling lamp and resolve the issue completely within 2 hours. Very methodical and accurate working - most appreciated!
I've used Electricians from Bright Spark 3 times to date , inc. a for a test certificate prior to buying my property. At all times the Electricians have provided a first class service with easy to understand advice and the work completed to a high standard. Many thanks to Karen and the Team.SC
This company was recommended by some people on the Nextdoor website. I wanted new lights installed in my kitchen, dining room and conservatory. Karen got back to me within minutes of my email and both Electricians proved to be efficient, friendly and tidy workmen. I will be keeping their business card handy for future use.
We were very pleased with the recent electrical work which was carried out in a professional manner by your electrician and will certainly use your company again when future needs arise. Also I would be happy to recommend your services to any of our friends.
