Diamond Avis 

If I could write the review without stars I would. Please see the message I got from this company today.

Sorry, we made a mistake

When your outstanding balance was reduced to £0.00, a system error meant we didn’t tell the credit reference agency. That left your credit file with the wrong information.

We’re sorry this happened, and for any worry this might have caused.

We’ve updated your credit file

We’re in the process of telling the credit reference agency your balance is clear and we’re updating your credit file, so you don’t need to do anything.

Just so you know, it can take up to six weeks for the update to appear on your credit file.

Why oh why do they make it SO difficult and expensive to make temporary changes to your policy. I’ve wasted an entire morning trying to do what should be the simplest task thanks to their wonky app and sub standard customer ‘service’. We have 3 vehicles insured with Diamond. I’ll be looking around very carefully at renewal this yr.

If I could give this 0 I would.
I've been with Diamond for 12 years and it was always fantastic. Every year my renewal price would go down, but I'd still ring them every year and discuss and they'd get it down another £50-150. They've now outsourced all of their customer service, so where you used to ring and speak to someone in Wales you don't anymore.

I rang through today because my renewal is over double my usual price and almost triple what I was quoted elsewhere.
Their new teams DO NOT CARE at all. They accused me of lying about how long I'd been with Diamond (because my policy predates their system!), they are rude, don't read your emails properly, and made no effort to try and keep you as a customer. Their customer service representative spoke so quickly with so much noise in the background I had to keep asking them to repeat themselves. They couldn't get me off the phone quick enough!
I then get an email telling me I was cancelling my policy and amending my excess (I did not agree to that), and so I went on their online chat to make a complaint.
It was worse than the phone! Absolutely clear the customer service rep was not reading my messages/had multiple cases on the go. They got my policy details wrong, said I have named drivers when I don't, got my dates wrong - it is an absolute shambles.
I cannot believe the fall in standards at Diamond. What a shame. Disgusting treatment from start to finish today.

My son had an accident last week and unfortunately his car was written off, but the whole claims process was far easier and quicker than we expected. The car was collected within 2 days and the settlement was paid within a week too — and was actually more than he was expecting. Communication was clear throughout and the online claims system was simple and easy to use. Really impressed with how smoothly everything was handled during a stressful time.

I’m 33 year old women, been with them 10 years and my renewal came through and was double my price last year. I have no accidents, made no claims. When I looked for a quote elsewhere they quoted me £700 less than my current insurer. Tried to see if they would go down on price but only took £129 off. Cancelled.

They have no loyalty to there customers and just trying to get money out of you hoping you accept there renewal price.

I am writing this as a warning to others: Stay away from Diamond Insurance. They may offer lower premiums, but the administrative nightmare that follows is not worth the "savings."

Before leaving the country six months ago, I sold my car and formally cancelled my policy. Diamond Insurance confirmed the cancellation and even issued a pro-rata refund. I thought the matter was closed.

The Issue:
Despite the confirmed cancellation, I am now being hounded by a debt collection agency for an "unpaid invoice." It appears Diamond failed to update their internal records correctly, and I am being penalized for their clerical error.

The Experience:

Zero Communication: There is no open line of communication to resolve this reasonably.

Harassment: I am constantly receiving emails and letters demanding money I do not owe.
Incompetence: They are quick to take your money but impossible to deal with when it comes to fixing their own mistakes.

Do yourself a favor and choose a reputable insurer. Diamond might be cheaper upfront, but you are simply inviting future legal and financial trouble.

Poorly managed company!
Never paid on time. Very Unprofessional, disorganised , you have to always chase up your payment to get paid.
I would never suggest this company.
There are more better company out there than u.

I've been with Diamond for over 10 years and never had a problem, they have helped me with multiple accidents and incidents and have always been really helpful.

They prices have always been reasonable compared to other providers too. Highly recommend!

Had an accident. That was my fault, they wrote my car off and gave me a value that was not even worth. 2k!!!! It's valued at 4k at least being a rare spec and colour.. they put the money in my account after refusing and I was told id receive a update.

They also removed my drive any car policy which I think is absurd as I was driving my main personal car insured with diamond.. IV had many emergencies where IV needed to go to the hospital and IV had to rely on taxis and get late for appointments. Also from a 2 litre BMW to a 1.6 litre auris, they refunded me £18.

What an absolute joke.

Will not be recommending anyone and my whole family will not be using these guys again.

Giving them one star because I cannot give them none.
For a static accident they wiped off about 10 years of my NCB for a claim of £3000 God forbid to have been in a real car accident with life thretening injuring and damaged both cars. Also missold the policy on the excess - DONT BUY THEIR INSURANCE WHATSOVER.

I've been with Diamond for over 15 years, 26 years driving and 22 years NCB and yet still every year they increase their prices. Despite them telling me they valued my custom when i said i found cheaper quotes, they could only bring the monthly fee down by £5. Absolute joke. So I've now switched to another company at £30 cheaper a month.

Amazing customer service from Jessica Evans helping me with my direct debit and adjusting my insurance policy details and Helped with my premium, I will definitely go with admiral diamond again for my next car insurance renewal

Tried to get a quote. Filled in much more information than they should have needed, only to get to the end and be told I already have an account so they wouldn't give the quote until I logged in. Tried to log in, but the email with an activation link never arrived. What a waste of time.

Used to be great - very easy portal and great customer service. In the last month I have had to renew my policy for a new car - it has been the most terrible customer service I have ever received. the portal seems to have become unusable and the call I made to the Indian call centre was almost unbearably bad - I was on the call for over an hour whilst she constantly went off the line to make changes and the customer service was painful. I have now used their messaging service to add a driver (which I used to be able to do online) - it asks me to us the Message Service as they need more information and the message service is non responsive. Have diarised to cancel the minute this comes up in March. Do not use.

Diamond are currently ignoring my GDPR request and it’s past the legal timeframe for them to respond, yet I still haven’t even had confirmation of receipt.

I will be reporting to the ICO

If I could give a 0 I would. I have been going through the claim process for over 3 months and still not resolved. Diamond Customer service is beyond dire. Have done everything possible to reduce claim to bare minimum. 1 star is for Laura in complaints. Will never use diamond or admiral again. Be warned!

I’ve been with diamond for years and their phone line customer service is great, you can always speak to someone clear and efficiently. If I have found a cheaper quote else where they are usually able to match the renewal. I’ve always found it to be the cheapest around for me. And I cannot fault the customer service.

It came to renewal time for my daughter, the price they sent us was over £200 more than last year. I got a way cheaper quote elsewhere, gave them the chance to match it, but they couldn't get anywhere near even though I'd been with diamond 7 years.
During the time in the chat section on line I was using (which is way to slow by the way) to get the renewal price down . I changed a couple of things in the policy. This then, even though my policy was coming to an end , generated a £15 charge. When I rang to ask why I'd been charged, i kept getting cut off,and when i eventually got to talk to someone they were so unhelpful. Really unhappy with this company. 2 hours of mylife I'll never get back!
Meant to specialise in insuring women, what a joke.

I want to specialy thanks to PRIYA SHAMA for her time and pation with me i was in a stuation with my policy and she realy helped me she was realy polite and very help full im realy satisfied and really happy with the customer service ive recieved today thank you PRIYA

After approximately 10 years as a customer, I’m leaving Diamond because the renewal process is a deliberate game designed to take advantage of loyal clients.

Every year, my renewal quote arrives significantly higher- often over £100 more than the previous premium, despite the fact I have never made a claim in the 14 years I have been driving. I then have to go through the same routine: call in, express concern, and am told, “There’s a loyalty discount we can apply.” Miraculously, the premium then drops back to a figure close to last year's. Even then, it’s still more expensive than what I could get with an identical policy from another provider.
This so-called “loyalty discount” isn’t a reward- it’s a pricing tactic. The process makes it clear that loyalty isn’t valued; it's exploited for profit and quite frankly it’s disgusting.
