Excellent EPC Training Provided - Thanks Hasan!

I recently had to undergo training to become a qualified DEA. Quidos sent out a very knowledgeable and friendly member of staff to train myself and 3 other colleagues. It was a 3-day course that explained how to produce an effective EPC for any property. I learnt a lot and the instructor was fantastic. If you are thinking about becoming a DEA, I would highly recommend Quidos!

Been with Quidos for a year now and spoke to Lorna today who was very helpful in the support providing ample information and help. Could not be more thankful.
I weekly call for support and speak to Arnie, Shay and Nick. Can not thank all three of them enough for all the help and support they provide me with.

Very informative and helpful technical support.
Followed up and phoned back (on 2+ occasions) when they said they would. Understood ones requirements and directed one to the correct technical sources to solve the issues raised.

Provided a good understanding of likely changes to EPC assessments.

Thanks again!

I have been working with Quidos since obtaining my DEA/RA qualification last year, which I also completed through their training. Throughout this time, I received positive feedback and professional support from the team at Quidos.

Most recently, I was instructed to carry out an Energy Performance Certificate assessment on a property that presented certain issues prior to my inspection. I conducted the assessment thoroughly and received comprehensive guidance from Quidos to ensure the report met the highest standards of accuracy and compliance.

I am sincerely grateful to Quidos for their continued support and commitment to professional excellence.

Positive Experience

Just finished my DEA course with Quidos. The on-line course was a really positive experience, the communication and support from Lorna was professional both before, after the course. Feedback from assessors was fair, and timely.

Utterly unhelpful if there is a problem.

The EPC surveyor had an unbelievably awful bereavement the day after inspecting my house with me. His email is down and I do not want to call him again. I told Quidos and offered to send them photos, plans and any evidence of the insulation I installed so they could complete an EPC. I trained as a Quantity surveyor years ago and was taught to work out u values so I am competent. They flatly refused and offered to give me the details of another assessor.

Reply from Quidos

Thank you for getting in touch.
Unfortunately we are not permitted to allow the lodgement of an EPC if the individual lodging the EPC has not visited the property themselves and collected the supporting evidence required for lodgement themselves. This is a very unfortunate situation with many sensitivities involved which is why our team offered to provide you with details of an alternative energy assessor if you required an EPC within a short timeframe. If you are willing to allow the original energy assessor some time following their bereavement we are sure that they will be able to organise the lodgement of the report for you, however if you would rather proceed without delay then we recommend contacting an alternative local assessor.

Outstanding DEA training with Quidos

I have undertaken training with Quidos. It was a DEA course conducted online with other participants. The trainer, Hasan Arif, was excellent and engaging with all of us. Very knowledgeable, patient and encouraging. It was better than expected. I highly recommend Quidos. Thanks Hasan.

Happy Move

Following the move from our former accreditation body, we have found Quidos to be a very good company to work with making the transition as smooth as possible. There were some initial hiccups with a confusion over CPD requirement dates that have since been ironed out. It has been refreshing to receive a straight answer to our technical queries in a timely manner the majority of the time. Quidos have been transparent when they have had capacity issues, resulting in slightly longer response times, though these are still a fraction of the wait time we were experiencing before joining them. As a national EPC provider we produce a large number of lodged reports and now have the reassurance that Quidos is sufficiently auditing our work so that we can ensure we maintain the highest standard of work we always aim for. Our accounts manager at Quidos visited us for a couple of productive catch ups, though they have since left. During the period between this and their replacement we have felt very supported by Billy. We use Quidos for TM44, SBEM, RdSAP and DEC lodgements.

I'm Sticking with Quidos

I was accredited with Northgate until it was sold to Elmhurst and briefly accredited with Elmhurst to which I didn't enjoy at all. I've been with Quidos now for over 8 years and have had a great experience and found the iQ-Energy software a perfect tool for completing my EPC surveys. The supporting evidence upload process has become simple and more user friendly which saves time.
The technical support has been great, when needed, and all of the team I have dealt with have been helpful, informative and friendly. Billy, Shay, Arnold and Catherine have been great over the years and I will continue to stick with Quidos as long as I lodge EPCs.
