James started on the tools at 17 and worked with British Gas for over 20 years before founding JWD Heating & Plumbing. The senior engineers all carry the same long-form experience, which is why we can survey, install and service every part of the system in one visit.

Yes. We are Gas Safe registered for all boiler, heating and gas work, and Refcom F-Gas certified for air conditioning. The cards travel with us on every visit, so feel free to ask to see them when we arrive.

We work 06:00 to 23:00, seven days a week. Genuine emergencies outside that window get answered too, but a callout fee applies. Most jobs are booked in during the standard working day.

Yes. Quotes are free and fixed in writing for installs, with no obligation. For service and repair work we'll give a clear price up front. Either call 07776 009 239 or send an enquiry through the form and we'll come back the same day.

Card, bank transfer and cash. Payment is normally taken on completion of the work. For larger installs we can split the payment across the start and end of the job, which helps a lot of homeowners plan.

A typical domestic boiler install lands between £1,000 and £3,000, including the boiler, the fit and the removal of the old unit. The exact figure depends on the brand chosen, the size of the system, and any pipework changes. We give a fixed written quote after a brief survey.

A like-for-like swap is usually one to two days from start to finish. Larger jobs, like a conventional-to-combi conversion or a full heating overhaul, can run three or four days. We'll give you a clear timeline as part of the quote so you can plan around it.

All major brands, including Worcester Bosch, Vaillant, Baxi, Ideal and Glowworm. We pick the brand that fits the home and the budget, and we'll explain the warranty differences in plain English so you can choose with confidence.

Yes, removal and safe disposal of the old unit is included in every install quote. You don't need to arrange anything separately. We leave the work area clean and take everything away with us.

Most of our installs come with manufacturer warranties of 7 to 10 years on parts and labour, depending on the brand and model. We register the warranty in your name on the day of install, and we leave the paperwork on site for your records.

We don't run a finance scheme directly, but we keep the pricing competitive and we can split the payment across stages on larger jobs. Card, bank transfer and cash are all fine, and the quote breaks down what's covered.

A standard annual service runs from £85 to £200 depending on the boiler. That includes a full inspection, clean of the burner and heat exchanger, gas pressure and combustion checks, and a written record for warranty and landlord paperwork.

Once a year. Annual servicing keeps the manufacturer warranty valid, catches small problems before they turn into expensive ones, and keeps the boiler running at the efficiency it was designed to. Autumn is the busy season, so book early if you can.

Most of the time, yes. We carry common spares in the van and aim to fix on the first visit. If a manufacturer-specific part needs ordering we'll tell you straight away, and we'll book the return visit for the next available slot rather than leaving you guessing.

Yes. We provide annual CP12 Landlord Gas Safety Certificates across Brentwood, Billericay and Chelmsford, and we co-ordinate access with tenants directly. The certificate is sent digitally on the same day.

Yes. Worcester Bosch, Vaillant, Baxi, Ideal, Glowworm, Viessmann and the rest. Two decades of British Gas time and ongoing manufacturer training means we can fault-find quickly and source parts fast.

We'll tell you honestly. If the cost of repair gets close to a replacement, we'll explain the trade-off and put a no-pressure replacement quote in front of you. The decision is always yours, and there's no hard sell.

Yes. Modern split systems run as heat pumps in reverse, so the same unit cools in summer and heats efficiently in winter. That makes them genuinely year-round kit, especially for offices, conservatories and home workspaces.

Most domestic single-room installs land between £1,000 and £2,000 fully fitted. Larger multi-split systems for several rooms cost more, but the per-room price drops once the outdoor condenser is shared. We give a fixed quote after a survey.

Yes. By law, anyone handling refrigerant in the UK must be F-Gas certified. We are Refcom registered, which is the trade body that audits and proves it. Using a non-registered installer can void the kit warranty and the homeowner insurance.

Mitsubishi, Daikin, Panasonic and Samsung are the main four we install. We pick the brand based on the room size, the energy rating you want, and the warranty you'd prefer.

Yes, once a year. The service covers a filter clean, refrigerant check, electrical safety inspection and an efficiency log. It keeps the running cost predictable and protects the warranty.

It's a deep clean of the central heating system. We push fresh water through every radiator at high flow with a magnetic filter on the loop, capture the iron oxide and sludge, then re-dose the system with corrosion inhibitor before re-commissioning.

Cold spots at the bottom of radiators, slow warm-up, banging noises from the boiler, or a thermostat reading that never quite matches the room are all signs. If you're booking a new boiler, the manufacturer almost always requires the system to be flushed first to keep the warranty valid.

Most jobs run from £375 to £900 depending on radiator count and how badly the system has been neglected. We give a fixed quote after a brief survey and tell you what we'll find before we start.

Most powerflushes wrap up in a single working day. We test every radiator for warmth top-to-bottom and walk you through the results so you can see exactly what changed.

A flushed system runs hotter for less gas, recovers heat output across older radiators, and protects the heat exchanger in your boiler. Think of it like an oil change for your heating, the running cost drops and the boiler lasts longer.
