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 does an air source heat pump heat my home?
An air source heat pump extracts heat from outside air and upgrades it with a compressor to provide central heating and hot water. It runs on electricity and pairs with correctly sized radiators or underfloor heating and a hot water cylinder to deliver efficient, low-carbon heat.
Are air source heat pumps suitable for older or solid-walled homes?
They can be suitable, but performance depends on insulation, heat-loss and your existing heating distribution. During the survey we assess fabric, propose insulation or system upgrades and advise whether a heat pump alone or a hybrid solution with your boiler is best.
How long does installation take?
Installation times vary by property and scope. A typical domestic install, including cylinder and commissioning, is usually completed over a few days; larger or hybrid systems take longer. We provide a realistic timeline as part of the quote.
What maintenance does a heat pump need?
Routine servicing keeps efficiency high and protects warranties. Annual checks on controls, refrigerant circuit and pumps are standard, SNT offers planned servicing and emergency support to keep your system running reliably.
Can you replace my boiler with a heat pump or install a hybrid system?
Yes. We design full heat pump replacements and hybrid installations that retain a boiler for peak demand. Each approach is assessed at survey to match performance, budget and any existing heating infrastructure.
