Essex and Suffolk Lettings are the worst business I have ever encounter.
(1) Huge fees. When we first agreed to let a house from then, they charged us nearly £200 each for 'finding' the property for us. They then charged us fee for signing the contract (about £100). They charge you a £35 re-inspection fee "to cover the costs of re-inspection" (they didn't re-inspect). They charged us £100 to renew our least for another 12 months. Finally, they charged us £143 each as a "moving out fee". Oh, and they also asked us to hire to a professional cleaning company to clean the carpets and launder the curtains. Note that this was not because they were dirty- they expect you do do this regardless of how dirty the house is. This of course will cost a considerable amount of money.
(2) Unprofessional service. The staff were not so much rude but absolutely clueless. We did not have a dedicated property manager. When asking the to fix a fault or when the property was re-inspected, we talked to a different person each time. This resulted us in having to contract them multiple times to report faults. There was, needless to say, a very long delay in repairing faults and it was often done to a poor standard- for instance a shower screen was replaced three times because the seal kept breaking.
(3) The agency was also slightly dodgy with their inventory of goods that came with the house. The house was meant to come with a Washing machine and dryer (but they said they would not repair them). Upon our first visit, they told us that actually the washing machine was broken, and that we would have to buy one. Okay, fair enough, we thought, and we signed the contract. Then when we moved in, we were told that the dryer had been vandalised by the previous tenant. Because they didn't do repairs to the dryer, this meant we had to buy a new dryer as well.
(4) Rapid rent rises. In our first year, the rent was £250 a month. This was, in hindsight, too high, as the house lacked a washing machine or dryer. The second year it was raised to £265. They have raised it to £280 this year, though thankfully we are moving out. Unfortunately some poor souls (naive students) have agreed to pay this absurd sum. I presume it is standard practice for them to raise the rent each year, hoping that you just won't bother with the hassle of moving out.
I cannot urge you enough to avoid using the services of Essex and Suffolk Lettings. This is especially true if you happen to be a student, as it seems that Essex and Suffolk Lettings are especially fond of taking advantage of students (I know of other students who have had similar experiences with them). If you are currently letting with them, I would urge you to leave as soon as the contract ends. If you are a Landlord, I would suggest that you chose a different letting agency or let the property yourself. You will probably end up with more enquires and happier tenants.
