Invictus did an excellent job installing a complicated (7 outdoor units) air to air heat pump system at Christ Church Parish Hall in Downend. System works well and installation team were efficient, careful and friendly. Happy to recommend them.

Excellent service from Invictus Mechanical. The installation of an air conditioning system in my wife`s restaurant was swiftly done in under a day, very tidy job at a good price, highly recommendable. Sam and his team were very knowledgeable and i was kept informed frequently as to the progress of the job Thanks Sam and the team. Geoff D.

Annual boiler service carried out professionally and efficiently. Very polite and knowledgeable engineer, very respectful of my property. An excellent company who give me total confidence in their abilities to maintain my central heating and hot water system. Used for over 5 year now and will alway us in the future. Fully recommend.

Really good service. Came out very quickly to diagnose an air source heat pump fault. Got the replacement part sorted and shuffled their week around to get the repair done asap as we had no heating or hot water. Well priced and great service. Highly recommend!

Our house needed a new central heating system and radiators fitted and after much research and getting quotes from various companies we chose to give the work to Invictus Mechanical Ltd. We found the whole process with them to be hassle free and straight from the get go Richard was amazing and offered us valuable information to assist with our choices. The work was carried out swiftly and any mess created was cleaned up at the end of each day. We are so impressed with this company that not only would we highly recommend them but we are also going to use them again in the near in the future.

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.
