Feedback From Our Customers
”George at Thames boilers has been great. Have used him on a couple of occasions and was always prompt , efficient and very friendly. He was even great with my nosy cat trying to get in his way. Had a hiccup with our new thermostat after he first visited and he immediately came within a few hours to fix it for us. Great service”
–M Hunter

”George was punctual and very reliable. He always turned up at the day and time agreed. Genuine, professional and friendly he carried out the work within the given time. He was good at communicating progress throughout the day and I appreciated him minimising noise during my daughters nap time! I would recommend George for any of your boiler needs.”

What Boilers Do We Recommend To Customers In Lewisham?

Vaillant
Vaillant are one of the best known boiler manufacturers in the UK. Vaillant were apparently the first company to make a “combi” boiler back in the early 1960’s. So they’re a well established company.
Worcester Bosch
Worcester Bosch are one of the best known boiler brands in the UK. Like Vaillant and Viessmann, Worcester boilers have won several Which? Best Buy awards.


Viessmann
Viessmann are the greatest boiler manufacturer you’ve never heard of. However, don’t let that put you off. They’re huge in Europe and, like their competitors Vaillant, they’re German and have been around for over 100 years.
Baxi
Baxi Boilers are another well established British boiler manufacturer, founded in the industrial revolution by Richard Baxendale, an iron founder, who began the Baxendale Company in 1866, based in Preston in Lancashire. Today, Baxi also makes well known Main and Potterton boiler brands, as part of the Baxi group. We usually recommend Baxi boilers as the least disruptive replacement for some heat-only boilers – and their Main boiler brand for people who want to keep costs down.
