haart - Estate and Lettings agent Milton Keynes Avis 

After my experience, several people told me it sounded like a scam. I’m sharing the details so others can make an informed decision.
1. Unexpected deductions. In the first two months, the amount deducted from my rent was £1,750 against a monthly rent of £1,400. The deductions were made up of around ten separate charges, which were not clearly explained to me beforehand.
2. Misleading sales information and unprofessional conduct. The sales team assured me there would only be a monthly management fee. Property management then applied additional charges. When I raised concerns, the communication I received was impatient and confrontational rather than professional.
3. Tenant management failures. The agency allowed the tenant to sublet a room, which was a breach of the tenancy. Also the tenant caused around £2,000 of damage to the property, and the tenant then moved out without giving notice.
4. Maintenance and contractor charging. I found their approach to tradesmen’s charges neither transparent nor fair. In my case, they also failed to resolve a boiler problem within a reasonable time.
5. Complaints process. The website describes a three-stage complaints procedure, but that was not my experience. Two members of staff altered wording and rearranged items in poorly laid-out statements in order to support their own position.
I would urge anyone considering this agency to ask for a full written breakdown of all fees and charges before signing.

Poor property management and even worse customer service, I would give zero stars if I could.

We moved into a property managed by Haart Milton Keynes on 2 July 2026 with our three young children. Within the first week, we started reporting a number of issues with the property. TWO MONTHS later, we were still chasing Haart to get basic problems sorted.

The downstairs toilet was unusable because of a leak and blockage. The carpet was in an awful condition — dirty, heavily stained, wrinkled and shrunk, with carpet grippers and sharp door-bar spikes exposed. Our three-year-old son caught his foot on them three separate times. Despite this, we were initially told that we could simply glue the carpet back down ourselves. Thankfully, after repeatedly chasing, the carpet is finally being replaced.

The en-suite shower has also been unusable, with the shower door coming off its runners and the shower itself subsequently being found to require further work. There have been issues with the toilet, French doors, windows and other parts of the property too.

The frustrating thing isn’t just that things go wrong, we understand that. It’s the way Haart have dealt with the problems.

I’ve had to repeatedly chase them for updates and arrange access for contractors. On one occasion, I was told a contractor would arrive in the morning, so I took a full day of unpaid leave from work to accommodate them. They didn’t arrive until the afternoon, meaning I lost a day’s wages for no reason.

I’ve also had some extremely poor experiences with the Milton Keynes branch when trying to get through to someone. I called Abbie after repeatedly trying to get an update. When she answered, she said, “Are you the one with the property issues?” I confirmed I was, was put on hold and then the call was disconnected.

My most disappointing experience was with Rippon. Rippon was shouting and swearing down the phone and told me, essentially, that if the property wasn’t up to my standards, I should find somewhere else to live.

I don’t think that’s an acceptable way to speak to a tenant who is raising genuine concerns about their home, particularly when there are three young children living there.

We’ve also had a ridiculous situation regarding a washing machine and fridge-freezer that were left in the property. They weren’t advertised or mentioned to us during the viewing, yet we were told that we should store them ourselves in the garage. We simply don’t need these appliances and shouldn’t be expected to give up our storage space for them.

Throughout all of this, we’ve continued to pay our rent in full. We’ve been flexible, allowed contractors access and tried to resolve everything directly with Haart and the landlord.

I’m not expecting a perfect house. Things break and problems happen. What I do expect is for a letting agency to take those problems seriously, communicate properly and treat its tenants with respect.

Unfortunately, that hasn’t been our experience with Haart Milton Keynes.

After everything we’ve experienced, I’ve now had to escalate the matter to senior management and am looking at taking the complaint to the Property Ombudsman.

I genuinely would not recommend Haart Milton Keynes. The property issues have been frustrating, but the lack of communication and the way we’ve been spoken to have been far worse.

I am appalled by the conduct of the Haart Milton Keynes branch. Since 11 March 2026, they have withheld our deposit without legal grounds. They attempted to override the landlord’s own instructions to refund us in full, choosing instead to try and claim "arrears" for a period where they already held the keys and exclusive possession of the property.

Only after persistent emails citing the Tenant Fees Act and the TPOS Code of Practice did they admit the "system" was clear and the rent was waived. Yet, 8 days later, we are still waiting for the transfer. This is a clear case of unreasonable withholding of undisputed funds. Formal complaint raised with The Property Ombudsman. Prospective tenants and landlords beware: their administrative incompetence is matched only by their lack of transparency.

Just had a letting viewing with Marta and Laura here in Milton Keynes. These two young ladies were very lovely, helpful and informative! Also,the property is quite nice! Thanks Marta and Laura! :)

I would like to Thank Dean, mortgage adviser @ Haart branch in Milton Keynes for his proffessionalism and kindness during my meeting with him yesterday.
He was really kind and helped me understand what is required of me and the possibilities I would have as a first time buyer.

I would 100%recommend Dean if you are looking for mortgage adviser. He was very proffessional, knowledgeable and kind.

Thank you Dean, God bless

Promised to complete a desktop property valuation for a remortgage but then disappeared without any response. They kept me waiting for a week and were later unable to find my request. Very disappointing service.

Very poor and bad service, lack of communication. Just make sure to document at the start of your tenancy because they are always ready to impose a false charges on you. They will always find a way to stress you.

Atrocious. Arrogant, incompetent, expensive. Once they've got you signed up are not interested in anything except getting more money out of you and their own furtherance, and certainly not interested in providing a good service to landlords.
Avoid at all costs, I didn't and they have cost me £1000's.

Haart has been misusing my personal data since 2021, when I was renting through them. Despite multiple complaints and a written assurance from their Data Protection Officer in February 2025 as well as their CEO Antony Lark that my number would be removed, they are still making unauthorised sales calls. I’ve now escalated the matter to the ICO for investigation. Totally unacceptable and unprofessional behaviour.

I had a very frustrating experience with haart Agency. I contacted them about viewing a property and explained that both my dad and my uncle who traveled down from London would be attending. I initially asked for a 2pm slot, but they told me this wasn’t possible because of an open house at that time. Instead, they suggested we join a 10am viewing.
I checked with my uncle, confirmed he could make it, and called the agency back to let them know we would be there for 10am. My uncle made the trip, but when we arrived, nobody from the agency was at the property. When I called to ask where the agent was, I was told the viewing “hadn’t been confirmed.”
This was extremely unprofessional and a complete waste of time — especially considering my uncle had travelled from London. If the viewing wasn’t confirmed, I should never have been told that 10am “should be fine.” It left us standing outside a property for no reason and caused unnecessary frustration.

I can highly recommend Haart as a letting agent, especially Ivonna she was so amazing and always very professional and friendly

Booked in advance to view one of the penthouses in Granton House. As we were coming from South East London we woke up early, excited to view and made our way to Milton Keynes Central on this very cold day. Met Haart onsite and after that all downhill! Key couldn't be found. We were told the manager was on his way and he would help to find the key. 5 minutes later we're told manager won't be able to come and not able to get access to the penthouse! I'm sure there's a lesson for buyers and sellers too especially as we were so keen. Oh well Haart off our list of reliable estate agents. Hoping to hear from the Branch Manager as Haart should be paying for the train tickets as a bare minimum as well as the hours spent traveling!

Haart MK are the worst branch I have ever had the misfortune to deal with, followed very closely by the Northampton branch.
Paid full rent this month as didn't know when I would be completing on my first home and moving out, but they've continued to hold my overpaid rent for weeks on end. Ivonna even sent me a screenshot trying to prove to me it had been paid but it showed a payment to the landlord, not me. 🤣
I've threatened Ombudsman, everything, and they just ignore you or pass the buck.
I've given them until the end of the day before I write more reviews and raise it with the Ombudsman, but I don't have high hopes.
Haart are the worst letting agents for both tenants and landlords (who also had nothing but problems with them and has now ditched them)
Awful, awful, awful.

A shameless company never respond to your call never respond to your email and they will detect the money just like they are earning the money please please please stay away from haart letting agency.
Especially from their property management team and a letting team from last few months I am trying to reach them and no one is responding. And my current tenant also contacting them but there are no one to respond them and on 19th of October tenant have to vacate the property but no response from them they are the pathetic company I ever seen in this letting industry.

Would have given them 0 if I could. Honestly the least professional company I have come across. Paid for a fully managed service which I have had to take over due to complete incompetence. Emails never answered and phones never picked up. Every time i put in a complaint they review their processes but nothing changes. I can not get rid of them until the tenant leaves which leads me onto the fact they can't even serve a section 21in the correct way. Avoid, Avoid, Avoid!!

The staff at Haart Milton Keynes were a pleasure to deal with. Especially Harry, Nick and Ethan who all went over and above their duties in a professional but friendly manner, even when there were problems in the sale, they ensured everyone was informed and things were sorted out and dealt with in a timely manner.

After having a bad experience we asked to speak to the manager. Alexander Dennehy called us and solved the issue. He then expressed his desire to come over to our house for a cup of tea. Alex is such a lovely young man with impeccable manners. He has put our mind at ease. Thanks Alex for the kind gesture

I had such high expectations.

Haart were the only estate agent to consistently call me to arrange a valuation. So hats off to this process, once I called back it was beyond difficult to find a date, however finally achieved after 3 separate calls. I chased morning of visit and still confirmed. However 90mins have past and no sign of anyone. Spending all night prior and morning getting ready with kids wasted.

Fuming and highly not recommended.

Ivonna has been absolutely brilliant in ensuring the repairs that I needed were carried out swiftly. She has been kind and professional and always took the time to listen to me. Thank you

I had opportunity to make complaint to Ivonna Dimpere and to be honest it was solved as soon as possible. This issue had been lingering on for almost 6 months but as soon she stepped in it was solved in a one week. She is really effective, hard working and trustworthy not that alone she is humble and quick to respond to issues. Thank you Ivonna Dimpere .You deserve more than 5*
Ivonna Dimpere 5*
