To give a bit of insight on what it’s like to be part of our endorsement scheme, we caught up with Sharon from High Efficiency Heating UK Ltd, a registered WAI and Which? Trusted Trader, to hear about why the company joined the scheme back in 2015, and how the business has benefited from the endorsement. 


Why did High Efficiency Heating UK Ltd join Which? Trusted Traders?

The general public can relate to Which? Trusted Traders. Offering our customers that extra piece of mind that they are in the best hands means a lot to us, and our company has gone from strength to strength since being part of the scheme.

How did you find the assessment process?

We found the assessment process straight forward. We appreciate the fact that you keep in touch regarding updated information, offer us advice on how to make the most out of the Which? Trusted Traders logo, and are always on the end of the phone to help with any of our enquiries.

How has your business benefited since becoming a Which? Trusted Trader?

Our company has gone from strength to strength since becoming a Which? Trusted Trader. Our customers can search for our Which? Page, where they can see all of our five-star reviews, which give them confidence to use our services. We direct our customers to our page at any opportunity - from our website, to our social media pages and even through word of mouth.


How are you using the endorsement logo throughout your business?

We use the Which? Trusted Trader logo wherever possible! The Which? logo can be found on our vans, on the windows of the office, on all of our documents such as invoices, quotes and central heating packs. All of the engineers and office staff wear uniforms displaying the Which? Trusted Trader logo, and we use it on our social media posts on Instagram and Facebook. We even have the logo on our brew cups in the office.
