This morning we had the pleasure of having our boiler serviced by O'Neil Gas and Heating, they sent an engineer who arrived on time and introduced himself as Alistair. All I can say is it was a pleasure to have him here completing a service and installing a Hive Thermostat. Alistair is a great representative of your business cannot praise him enough.

Boiler was fitted efficiently and well, and looks neat and powers the warm water and heating well. Gas engineer was friendly and the check up phone call a week later was appreciated. Thank you.

This is to say “thank you, John” for being so friendly and helpful and patient and professional when helping us to get to know our new boiler and its hive and ensuring that our central heating system works efficiently. A really good experience!

We are an elderly couple . Our boiler needed parts and was dealt with efficiently and quickly so that we were not without heating and hot water any longer than need be while they got the parts . Staff on the phone are polite and very helpful . Been with this company for a few years now and would recommend them.

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.
