Phone number ☎️ 01603511690 👆 is reported as a persistent nuisance caller targeting UK residents with unsolicited calls about supposed free solar panel safety checks and maintenance. The number often displays caller knowledge of personal details, creating an impression of legitimacy, but the majority of recipients report it as a scam or aggressive marketing tactic.

This morning on 6th Feb I got a ring from 01603511690 about some safety inspection supposedly needed for my phone. Never come across this sort of thing before so I told the bloke to ring me at a different time. Definitely not interested in taking up that so-called 'service'.

They kept ringin me back to back, like 6 times, just to try and pester me into buying something.

I got a call from them yesterday but I just didn't answer, found it really irritating.

This number has phoned me a couple of times, but my spam filter caught them and stopped the calls. Honestly, whoever owns this number needs to be taken to court for hassling people like this.

Just got my solar panels sorted and updated by a nearby firm, so I really don't need any more calls about checking them again. Sounds like those could be one of those solar panel scams.

Got a call from this number saying they had a free spot on Wednesday to check my solar panels. They asked if it was okay to pop round then. I said no, and the lady seemed a bit flustered but then asked if another day would work. Honestly, I should have just let them do what they wanted, but since I don’t even have solar panels, I told them no. Definitely felt like a scam!

I’m so done with this number, always rings but no one says a word when I pick up.

Some bloke rang me saying he was from DLBeck and needed to sort a free service check on my solar panels, claiming it was needed for my MCS certificate. I was pretty sure it was dodgy, so I asked him to send me a letter instead. He wouldn’t agree and then tried to get my email, which I didn’t give him. He kept pushing, asking when he could ring again, real persistent this one.

Got a call about a solar panel safety inspection, which I’m pretty sure was a scam. I told the bloke we weren’t interested and ended the call. Even after we blocked the number, he kept ringing us back. Seems like he’s not the brightest!

For weeks now, they've been ringing pretty much every day, often from a mobile number. One time, the person on the line was really rude and aggressive towards my husband.

I was trying to set up an appointment to have someone look at the wiring for solar panel installation. Honestly, it was quite difficult to catch what the person on the phone was saying.

Apparently, I qualify for a free yearly solar panel health check. Nah, thanks but no thanks, sounds like a total scam to me.

Beware of this company - they’ve been pestering customers with solar panels constantly. I wouldn’t recommend doing business with them at all. If you think there’s an issue with your solar setup, it’s best to contact the firm that originally put it in, since your warranty should cover any problems.

Got a couple of calls on the 1st of July from someone claiming I needed a yearly check-up for solar panels. Honestly, no idea how they even knew to say that since we don’t have any solar panels here. Weird situation!

I’ve been getting calls from this number, with the callers saying they're from MCS, the folks who certify solar panel installations. They’ve been insisting that it's time for our yearly maintenance check and are trying to set up an appointment to look over our system. However, after reaching out to MCS directly, they assured me that they absolutely do not operate this way. Seems like this could well be a scam or some kind of high-pressure sales tactic!

I had two phone calls from this number earlier today, yet there was no voicemail or message left! Quite odd, isn't it?

I just ignored the call, didn’t even pick up.

This caller was incredibly insistent, ringing me just a minute after our previous conversation ended. They insisted that our yearly solar system maintenance was due, but that’s simply untrue. It feels rather pushy to receive two calls in such quick succession. In my opinion, it's definitely a scam.

I received a call with no one on the other end. Quite puzzling, really!

Got a call from 01603 511690 about a yearly solar panel check, and they already knew my name and where I lived, asking if they could come round the next day. They said they were from DLBEC Ltd, which shows up as a call centre company on the government register. Even though I've blocked similar digits before and signed up to the TPS, these calls with my personal info keep flooding in. Honestly, it feels like blocking numbers or the TPS does bugger all!

Some bloke rang me and said the company he was calling from, but I honestly can’t recall the name now. He started off by asking how I was doing and a few polite bits and bobs before saying it was about our yearly free inspection for the solar panels.

Got a call offering a free check-up on solar panels. I told the bloke he was breaking the law by getting my info without permission and calling me out of the blue. Asked him to delete all my details from his records. Ended the call before he could even answer.

They said they were giving a "FREE" solar panel health inspection, but then suddenly switched to talking about the inverter. Creepy thing is, they had my exact name and address, though I suppose that info isn’t hard to find these days. They were super pushy, and definitely not honest, especially if you know a bit about MCS certification and solar EV stuff. For those who don’t, it might sound very convincing. I’m sure loads fall for it. Best to steer clear of these lot.

I saw the info and decided to block this number straight away. It was so frustrating because it only rang once, just as I was having an afternoon nap, and it really annoyed me.

I keep receiving calls from this particular number, and it’s becoming quite the nuisance. If I don’t pick up, they simply hang up, and if I do answer, they just drone on about solar panels. They even have the audacity to claim that we’d arranged for someone to come over and assess them, which is entirely untrue-there was never any such agreement! It’s ridiculous, especially since we’re registered with the Telephone Preference Service, yet these interruptions continue unabated.

Like others have said, this lot must have got my info from somewhere else cause they definitely didn't get it from me. I told the bloke I already have a crew who look after my solar panels, so I ain't interested in his so-called "free" service.

Got another annoying call again!

Got a call from a bloke claiming to be with DL Bec, talking about a 'free electrical check' since apparently they've taken over from the MCS contract. This was like the fourth call this week from different companies with the same spiel, so I suspected it was dodgy. I checked and DL Bec is a real firm based in Norwich, but the number they called from didn’t match theirs. I'm on the TPS, so I've reported the call.

I answered a call from this number, and when I asked who it was, all they said was some mumbo jumbo I couldn’t make out before they hung up. Seems like a scam to me, so I’m gonna block it. Shame though, I thought it might of been a mate from 01603 who’d forgotten to save their number.

I wasn't too sure what that call was about. They asked something about the wiring for our solar panels, but I told them everything seemed alright and then ended the call.

Received a call purporting that the government was funding inspections on photovoltaic systems. As someone in the PV installation business, I'm well aware that this is a load of nonsense. They promptly ended the call when I challenged them on it. I'd say it’s highly probable that it’s a scam-steer clear of them! It brought to mind a certain company, found here: https://www.dlbec.co.uk/ While they mention MCS during the conversation, the "Our Accreditations and Affiliates" section on their website merely states, "We take pride in being a trusted associate of leading renewable energy professionals and organisations." If they were genuinely MCS accredited, or held any other relevant certifications, I reckon they’d flaunt that information prominently. Everything about it seems rather suspect, doesn’t it? Should your PV setup genuinely require an inspection, I’d recommend enlisting a local installer who comes highly recommended by your community.
