Today, I specialise in a wide range of plumbing and heating services, including: • Boiler installation and replacement • Air conditioning installation • Heat pump systems • Underfloor heating • Complete plant rooms • Bathroom installations • Kitchen pre-plumbing • All general plumbing work and maintenance I take pride in providing high-quality workmanship, reliable service, and solutions you can trust.

Gareth, the proprietor of GMS is a qualified wood machinist by trade and has over 25 years’ experience working within the construction industry.

In the last 10 years the business has diversified and now accommodates a scheme of works within construction from kitchens to bathrooms, gardens to bedrooms, fire and flood damaged properties and more. Gareth employs several staff and subcontracts to NICEIC registered Electricians and GAS SAFE registered gas engineers. Therefore, GMS can offer project managing and the client only needs to converse with one trade [GMS] rather than multiple. Thus, taking the stress out of the job.

Called me ten minutes after placing the request. Daniel immediately arranged to do the job the next morning and gave me a cost at the same time. He called me twenty minutes prior to his arrival. When he arrived, we discussed the work in more detail and he completed everything very quickly and neatly. Provided a test certificate as requested. He was a very pleasant and professional. This is what I expect from a company who is registered as a NIC EIC electrician and would recommend others to do the same.
