Would highly recommend – 5*

After have a lot of trouble with our first architect a friend put us on to GR Engineers. After one phone call they arranged a time convenient to us to come round and go through exactly what we wanted. They also gave us a lot of ideas and suggestions we had not thought of to make the end result better. Within a week the plans had been drawn up and submitted to the council who approved them without any querys.
We now have an amazing house that is better than we could ever have hoped for.

All went smoothly – 5*

GR Engineers took care of all of the planning & building process of my project, from start to finish. They did an outstanding job. They were reliable, very professional, always contactable and happily answered any questions/doubts I had about the process. Planning permission went smoothly and the construction job was done on time and within the budget.

This company is actually really good, I used another company from this site yell.com but the guy took six weeks saying my proposal for back extension has been declined.

So I spoke to GR engineer: Mohi, he advised on very small adjustment, re negotiated with the planning committee and then got approval with his new drawing plans as well all in 6 days. I should have used GR from the start so by now I would have a new bedroom and kitchen. GR also managed and organised to source the builders for me who has already started the work.

Absolutely superb service-six out of five star – 5*

I was unable to obtain local council approval for calculations related to an application for a single storey rear extension and loft conversion. The council continued to identify issues with submissions made by the engineer I had initially appointed which was delaying the completion of my project. I decided to cut my losses and appoint GR Engineers. Within 10 days they inspected the site, produced revised calculations, discussed the situation with the local council and submitted revised calculations which were subsequently approved. Within that time they also met my builders and discussed the impact of the changes to minimise the delay which saved time and money. I highly recommend using GR Engineer Ltd for all structural engineering needs

Excellent, Efficient and Reliable! Do not overlook! – 5*

I was saved by Mohi after a terrible experience using one of the big national firms that delayed my build.

Mohi picked-up the drawings and amended them where he saw there were issues, and presented his findings clearly and competently.

Turnaround was in no time and I am very grateful for this after being delayed by the previous firm with excuses of which Mohi gave none – he simply did his job brilliantly at that.

I trust Mohi and GR Engineers, and highly recommend his services from drawing to structural calculations etc.

The cost was very reasonable and of course this is a big factor when finding an Architect/Engineer.

I have referred my clients to him; as I know how well he undertakes his work and will continue to do so.

Do not overlook for a national firm as there is a marked difference!

Completing plans and building calculations to a high standard – 5*

Excellent expert service, advice and support. Plans completed to tight deadlines which were expertly produced. Local council passed all plans and calculations as accurate enabling me to proceed quickly and efficiently. I would highly recommend this company.

High standard of work – 5*

Mohi has been so helpful for my plans of 2 storey side extension and loft conversion. He came up with idea of building the loft 1st then 2 storey side extension. I am letting the side extension part with a separate side and rear access from outside. All the structural calculations were done by him and they were accepted by Redbridge building control. During the construction time, he advised the builders about many technical things. The cost of the drawings and structural calculations were very reasonable compared to his services. I highly recommend him for the architectural drawings and the structural calculations.

Efficient and Wonder services by Professional – GR Engineers Ltd – 5*

I am lucky to involve Mohi with his company at my rear extension and Loft conversion works. He and his team have done all the drawings and structural calculations on time. He has never charged me for any amendment of the drawings or planning. When I had critical time with building control and builders and do not know really how to deal with those situations , Mohi visited on my site and dealt with queries from building control. He explained my builders about the necessary works to be done on site. As a result the building control’s inspector was happy for the overall works have been done by my builders and i have received my completion certificate.
