First class service from the start! This family business was recommended to us.After being let down by so many Plumbing Companies,Marriot was a breath of fresh air. Ross arrived within the time slot allocated and carried out a very detailed service which took approximately 35 minutes. He then moved on to another property and recommended various repairs and tested gas safety. Im confident that these repairs will be carried out to the highest standard as quickly as possible. What a friendly,professional Heating Engineer Ross is and explained all aspects of the boiler service. This company has been second to none and im delighted to support a local business. I have no hesitation in recommending Marriot .

Brilliant service with very quick response and repair. Broken boiler fan was replaced within a couple of hours of calling the office. Ross was great, very friendly and informative. Have also used Marriott for leaks/radiator replacement and have found the work to be very reasonably priced too.

New Boiler and Flue installed last week, Darrin went the extra mile to get a Flue solution as the old Flue was now non compliant. Super impressed with him and his team of engineers and recommend them to anybody for new Boiler install works Thanks all at D.Marriott Plumbing and Heating Regards Innes Muir

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
