TrustMark Reviews 

I am extremely dissatisfied with the service and customer care I have received from both a TrustMark-accredited installation company and TrustMark itself. The installation company in question, energy efficiency group, blatantly violated TrustMark’s code of conduct, and despite providing irrefutable evidence of their misconduct, TrustMark failed to take any meaningful action. This raises serious concerns about the validity and purpose of this governing body, which promotes itself as being endorsed by the government.

The installation company demonstrated unprofessional and unethical behaviour throughout the process relating to our ECO4 application for external wall insulation. Not only did they lose my personal documents i.e.bank statements, but also attempted to intimidate and make threats. Nearly six months after the installer self-signed off the work, the two directors of the company Gurpreet Lamsar and Jugbir Bhangoo, visited my home unannounced and left a handwritten note as a warning, demanding bank statements to re qualify for the ECO scheme a third time! This note included the explicit threat to dismantle the external wall insulation they had carried out, and claimed ownership of the materials, along with accusations of fraudulent activity. Such behaviour is utterly unacceptable and demonstrates a complete disregard for customer care and professional standards. Furthermore, their workers were unskilled and as a result they left two areas of an external wall without insulation, which I suspect does not meet the purpose or standard of the scheme. Trustmark failed to carry out an inspection to identify the issue.

Despite these clear breaches, along with evidence of incomplete works, TrustMark’s complaints procedure proved entirely ineffective and appears unfit for purpose. Similarly, the British Assessment Bureau and Ombudsman, which form part of Trustmark's complaints process, ignored the facts presented, turning a blind eye to the situation and further eroding confidence in the process.

No action was taken against the installation company, which leaves me questioning the integrity of TrustMark as an organisation. It appears the TrustMark logo is little more than a marketing tool, designed to lure unsuspecting customers into a false sense of security, rather than providing genuine oversight or protection.

Follow up emails were sent to Trustmark's dispute team more than two weeks ago, but they have again failed to respond.

I would strongly caution against trusting any company that displays the TrustMark logo. My experience has shown it to be a hollow assurance that does not guarantee ethical conduct, professional behaviour, or competent workmanship.

*Update July 2025* - A recent independent inspection of the installation works carried out by the funding body confirmed that the work failed to meet the required standards under the ECO4 scheme. As a result, remedial works were ordered.Following the completion of these additional works, company director Gurpreet Lamsar—who is also a member of the competent persons scheme—failed to keep his promise to return with details of a warranty to cover the further work carried out to the roof and guttering. This ongoing lack of accountability and failure to follow through on assurances continues to reflect poorly on both the installer and the organisations meant to oversee their work.

We worked with the TrustMark team on a project involving retrofit assessments and on-site filming. As the UK’s trusted quality assurance organisation for home improvements, they represented their mission exceptionally well. From the first communication to on-site work, Georgina, Rhys, and the team were professional, knowledgeable, and warm. They ensured everything ran smoothly and reflected TrustMark’s standards perfectly. Even sending the homeowner a thank you gift for allowing us to use their home for part of the project. Follow-up communications were equally efficient and the whole team that interacted with them would highly recommend.

I used a Trust Mark registered business for solar panels. The company completed the work in one day and were very professional.
I always try to use businesses that are Trust Mark registered.

Enjoyable couple of hours - talking about Trustmark and how this benefits us with placing ourselves in the high quality installer bracket for our Solar PV, EV Charger and all electrical works

Spoke to TrustMark on the 2nd of December 2024 @ 12.25 (phone call recorded) about Tort of Negligence by a company under the directorship of Nick (Muhammed Naeem) owner of Powering up Briatin Ltd trading as Britain Energy. They advised me it would be 10 working days to get back to me. I called them on the 17th December 2024 @ 14:09 and the lady asked me loads of questions and she stated the dispute team will call me back, (phone call recorded) they didn't call back. So I called back again today 18th December 2024 @ 16:46 (phone call recorded) and a very rude lady answered the call (working from home, dog barking in the background) called Janet, who showed no empathy, or compassion, or care, and no respect, and her tone was quite harsh. She told me it is 10 working days, I said "let me check", and worked out today was the 13th working day passed. She was quite rude in her tone, and I suggested she should get some customer service training in how to talk to 'customers'. I bet they treat businesses with much more respect!

What is the purpose of this 'not for profit' organisation just so rogue businesses can affiliate with themselves with them to make themself more worthy and professional!

If dispute team don't respond I will contact my local MP as they are using government funding for payments, and using rouge traders!

KM services nationwide LTD did my attic insulation and when they put back the radiators they didn’t connect them to pipes and water leaks and damaged my whole carpets water went through atttic all the way down to cellar the inspector visited my property and was not happy with the work that was carried out and informed Km services to rectify the issue but still have not done anything I have sent them sn invoice for my damages but they debating about tye pice. They have damaged my carpets so they should pay but they don’t want to.
I Strongly don’t recommend this company to do any government grant work. They are not professionals but a set of cowboys.

The website is very useful for finding qualified and accredited companies and individuals

TrustMark are active and responsive. What more can you ask for from a company with the sole aim ensuring compliance and quality.

Most importantly, they provide useful information that is readily available to all who need it!

Including us at AD Watts Electrical. We are happy to be affiliated with them.

An endorsement from Trustmark is completely worthless. In fact, you are likely to get a complete cowboy builder as they will use the quality mark from Trustmark to hide behind their inadequacies. Also be warned about what Trustmark say about managing a build, again completely worthless. My advice is simple: -

1. Do not pay a deposit,
2. Check to see if a builder has any outstanding court judgements
3. Have your own contract from the Kitchen and window people
4. Manage your own internal works for example flooring and fixtures and fittings. Painful but worth it in the long run

Please read other 1* reviews on this site as they are broadly in line with my experiences.

We needed our electrical sockets raised as we're not getting any younger and couldn't reach the plugs! So contacted P W STEVENS (Trustmark) here on the Isle of Wight and he fitted us in promptly. A competent electrician who listened to what we wanted and complied to the letter. We shall certainly recommend him to our friends and family.

We employed P W Stevens to update our shower extractor. He was very neat, tidy, efficient and his work was very reasonably priced. I highly recommend him.

I eternally grateful for the work that was done on my house. Thank you to the company, and all the workforce that were involved to make my house more energy efficient, its amazing. Thank you

We had gas central heating installed and the work was completed within two days. They worked hard and made sure they cleaned up We also had an electrician to connect the boiler and a joiner to ‘box in the pipe work……..(licence number 2520837)

Can't believe they only have two companies cover guttering/fascia work, one is over 8miles away one is over 27miles away. When I do a whole London search, the result came up with companies in Leeds and Newcastle. What are they doing? This is complete rubbish. Have all the builders gone to use Checkatrade and Trustabuilder platforms? This is a government backed website, should do much better.

Very poor experience with Trustmark affiliated Trade and FMB.

We engaged an FMB affiliated Trade (Dunamis Construction) that can’t be bothered to complete a job, respond to email or even return outstanding Deposit.

Quality of work is shoddy, extractor fan stopped working after a while, plasterboard on new bathroom has now caved in, there’s leakages and dampness all along the wall and even tiles broken during fitting wasn’t replaced or fixed.

We went for ADR provided by FMB and this seems to emboldens the Trade further and the Trade simply refuse to pay a sum it voluntarily agreed to.

And what does FMB say, “we've escalated this internally for investigation and may at our discretion refer to a Standards Committee” so no visibility or transparency or accountability.

Question is what is trustworthy about this and the company still proudly displays the Trustmark logo and number of years its been a member.

Full support and guidance given to our Retrofit Team at Graysons to lodge some highly technical installs to ensure our clients meet their SHDF deadlines. Greatly appreciated!!!

Trustmark is a valued brand and one which we promote to our customers and potential customers.
The site is professional looking and gives members and prospective clients confidence.

I had solar and ASHP installed in two houses.
Never would I have believed such cowboys could get away with what they have done. Bluff and misinformation, appalling standard of work and responsibility.
I have a Trustmark certificate but it's not worth the paper it's written on. Complete scam

Don't waste your time! They didn't want to help when one of their members ripped us off thousands.

Had a TrustMark business work on my house, as recommended by our housing association.

Had all new windows and doors replaced, the communication was great and done all in a day by 2 men. The house feels a lot more insulated and looks lovely they did a great job. Any damage was fixed straight away.

Unfortunately 2 of the bedroom windows had a problem and I wasn’t able to shut them, but this was quickly rectified.
