What we do with boilers

New boiler installation

We size the boiler to the heat loss of your property and the hot water your household actually uses, not to whatever was on the wall before. The old boiler is taken away, the system is cleaned and protected with a filter and inhibitor, and you get the warranty registration and building control notification handled for you.

Servicing and safety checks

An annual service keeps the manufacturer warranty valid and keeps the boiler running efficiently. We test combustion, check the flue and ventilation, inspect the seals and safety devices, check system pressure and water quality, and leave you a written record.

Repairs and breakdowns

Lockouts, pressure loss, no hot water, noisy pipework and error codes. We diagnose the cause rather than fitting parts on a hunch, and we will tell you honestly when a repair is worth it and when it is money better spent on a replacement.

Frequently asked questions

How often should a boiler be serviced in the UK?

Boilers should be serviced at least once a year to maintain safety, efficiency, and manufacturer warranty requirements.

When should I replace my boiler?

If your boiler is over 10–15 years old, frequently breaks down, or becomes inefficient, replacement is often the most cost-effective solution.

What type of boiler is best for my property?

This depends on property size, water demand, and existing infrastructure. A professional assessment is required.

Is it worth investing in a high-efficiency boiler?

Yes. Although the initial cost is higher, long-term savings and reliability typically justify the investment.

How can I extend the lifespan of my boiler?

Annual servicing, proper system use, and timely repairs are essential.

How much does a new boiler cost?

Every boiler job is priced on the system, not from a price list. What you pay depends on the make and model that suits your home, the output you need, whether the position or system type is changing, and how much pipework and controls work is involved. We survey your property free of charge, talk you through the options at different price points, and give you a written fixed price before any work starts. No day rates, no extras added later.

How long does a boiler installation take?

A like-for-like combi replacement is normally a one day job. A system change, a relocation or a conversion from a back boiler takes two to three days. We aim to leave you with hot water the same evening, protect your floors and carpets, and take the old boiler and packaging away with us.

Do you remove the old boiler, and what warranty do I get?

Yes, removal and responsible disposal are included in the price. New boilers come with a manufacturer warranty that varies by make and model. We tell you what the warranty is on the boiler we recommend before you commit, register it for you, and guarantee our own workmanship on top. Your installation is notified to Gas Safe and your Building Regulations certificate follows by post.

My boiler has broken down, how quickly can you come out?

Call 07808 899464 and we will get to you as fast as we can, and we aim for the same or next working day for no heating or no hot water across London and Kent. We carry common spares on the van, so many faults are fixed on the first visit, and we will always tell you honestly whether a repair or a replacement is better value.

Which areas do you cover?

We install, service and repair boilers across all of London and Kent. That includes every London borough, and Dartford, Bexley, Bromley, Greenwich, Sevenoaks, Tonbridge, Tunbridge Wells, Maidstone and the surrounding villages. If you are not sure whether we reach you, call 07808 899464 and ask.

Do you work on commercial buildings?

Yes, and a large part of our work is commercial. We hold the accreditations needed to design, install and certify commercial heating, hot water and gas plant, and we have completed projects in schools and churches as well as offices, restaurants, care homes, hospitals, apartment blocks and multi occupancy buildings. We are used to working in occupied buildings and will plan the work around term times, services and opening hours.
