Delta have just installed an Air Source Heat Pump in my property. Prior to this, I had just been let down by Octopus Energy who couldn't install the heat pump because the house is a special Passive House build. Delta stepped in and delivered way beyond my expectations. The challenges that blocked Octopus completely seemed like mild inconveniences for Chester and the team and my house went from being impossible to fit a heat pump to the most natural looking installation in just over a week. I'd highly recommend them to anyone wanting a heat pump installation done right.

Delta handled our change from old electric storage heaters to a new air-pump heating system. Our house is circa 1925 and small and cluttered, so the job was never going to be easy! However the engineers from Delta were very knowledgeable, pleasant, professional and handled everything in their stride. Any issues that I flagged (which were few) were handled very quickly. Really *very* happy with the work and how friendly and professional the team were! Great bunch of guys!
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.
