SEHBAC Founded over 40 years ago, the S.E.H Group comprises of 10 recognised brand subsidiaries involved in all aspects of civil engineering, construction, home improvement and related services. With headquarters in Suffolk and 14 other regional offices, the S.E.H group (with an annual turnover of circa 130 million), operates nationally for clients, including the Environment Agency, the NHS, Crown Estate, Highways Agency, Atkins, Persimmon, Taylor Wimpey plc and many regional councils. The S.E.H Group has over 500 employees who deliver infrastructure and construction projects, including new home and office building, road, motorways, bridges, docks and town centre redevelopments.

In July 2007, S.E.H. & BAC joined together to expand their service throughout London and the South East. BAC, a name synonymous with quality and value, was already a leading brand in the home improvement industry. The ethos of both companies was perfectly matched. SEHBAC is rapidly becoming a household name and new show centres are planned to continue the expansion.

They also require the fewest muntins, which are panel-dividing strips, so provide the best views and let the natural light in.

Ordered in Aug 2020, Installation started in April 2021 and we are still trying to resolve problems - 1 year on. Had 11 windows plus 2 doors fitted of which 5 had major faults to the frames and 1 window misted up. All had to be replaced and this took 5 months to resolve. We were unable to talk to management to try and speed up process. Then Jan 2022 - 2 more windows started misting up and they have just been replaced (10 weeks) and 1 of these is faulty and we need another replaced. Avoid using SEHBAC at all costs - their quality and service is a disgrace.

This morning the driver of an SEH van with the registration number ending in ZFW was very aggressive and gestured profanities towards me because he didnt want to let me pull into the inside lane of the A12. I don't feel that a man with this aggressive nature should be in peoples homes fitting windows and conservatory's. I will certainly never deal with SEH as a result and I will be sharing my opinion whenever the opportunity arises.

TRULY CONSERVATORY REPAIRS. Ashton under Lyne
Would certainly not recommend this company. A rude, belligerent, arrogant and unprofessional manager that does not like complaints. Shoddy and poor workmanship. Turned up when they felt like it. Leave a job half finished and walk away. They do not possess the skills, and professionalism to carry out specialist work or any work at all.

Above all, neither do they leave the job tidy or clear away their rubbish. Rather a slapdash outfit with sloppy working practices at high prices for an unsatisfactory job. Not worth 1* I would grade this outfit - * 00. The whole job this company did was a nightmare from start to finish. Now there is a problem of getting them to put right a more than rotten job and not a cat in hell's chance of them doing it properly.

All faith in this company is nil. Does not answer mail or take kindly to criticism. Should have read Which Reports before getting involved with this terrible company Be warned. I wish I had looked at reviewcentre.com and also done more research on who I was getting. A slick website(s) with fairytales attached. Could have done the job better myself.

Visited showroom to get details on having a conservatory. Had to find a sales person to help as nobody appeared for 15 minutes. The rep asked which one I liked and quoted a figure nearly twice what I had in mind. I said I could probably have a whole extension for that. He then asked how much I expected to pay, when I told him about 10,000, he just pointed to a different one and said "you can have that one for 15,000".

He didn't bother to ask me what I wanted to use it for, or to go through any other options. Was completely uninterested in the whole thing. I shall take my business elsewhere. I'm not paying for their commission and overheads.

Friendly staff and hassle-free installation. Very happy with the overall product - looking forward to using our new conservatory in the summer. I'd certainly recommend SEHBAC to our friends.

Our new conservatory was installed by SEHBAC and we love it. Our garden was a strange shape, but they managed to fit in everything that we wanted. Great service and even now in the winter its beautifully snug and warm. Great service, great company.

I have just had a conservatory installed by SEHBAC, the team were very friendly and tidy, cleaning their mess up after themselves. My conservatory was built within the week and is excellent quality, the self cleaning windows are a life saver, no more fingerprints to clean! There is not a better company out there.
