I have found Sam, Cody, Zoe and their Team, amazing to deal with. They have also done an excellent and prompt job of installing a New Vaillant Boiler and 8 New Radiators in my home in a day and a half, with no mess left at all. I would highly recommend them for Gas Engineering and Other Plumbing work!

Frequently Asked Questions
How long does a typical boiler installation take?
Most domestic boiler installations are completed in one or two days depending on whether pipework needs altering, whether a new flue is required and the property type. The engineer will confirm a realistic programme during the survey and include it in your written quote.
Will you remove my old boiler and dispose of it?
Yes, we remove your existing boiler and give you the option for responsible disposal. Any additional materials or access work required will be detailed in the quote so there are no surprises on the day.
Do new boilers come with a manufacturer warranty?
Manufacturer warranties apply when installations meet the brand’s installation standards. Because we’re Viessmann, Worcester and Vaillant-accredited installers, we complete the necessary commissioning and registration to protect the warranty where applicable.
What information do you need for a quote?
We need to know your property type, existing boiler location, preferred boiler brand/type and any known issues with pipework or controls. A site visit allows accurate measurement of flue routes and pipe runs; after the survey we provide a written, itemised quote.
Are your engineers Gas Safe registered?
Yes, all heating works are carried out by Gas Safe-registered engineers. We hold manufacturer accreditations and complete the required certification and paperwork after installation to meet building regulations and safety standards.
