Epc provided a first class service baring in mind I did not have a service contact with them. Their customer service was first class and the communication with their service engineer was brilliant. As this my first encounter with a heat pump I have decided to take out a service contract with Epc and this was made a lot easier when using the 2 ladies in the service department.

I've been working with EPC Improvements since June last year to have an in-roof solar solution installed into a property I bought back in February - they were incredibly patient as we waited for our chain to complete and kept in regular contact throughout. Once we moved into the new property in February, EPC Improvements attended the property very quickly for the survey and within a few weeks the final solution was designed and delivered. Everyone at EPC Improvements were fully committed in terms of their customer service and approach, each a credit to the business. A big shout out to the following people for going above and beyond to get us over the line: Fraser - for brilliantly handling the initial contact and conducting the survey - whilst also taking a bit of time to throw in a bit of dog training when he visited ! :-) Kai - Excellent forensic analysis of energy usage data and providing design and costings promptly, attending site to ensure suitability and taking almost never ending calls from me to help with all my questions. Neil - Brilliant Organization of the teams that were responsible for the deployment of the solution and keeping in contact when any very minor challenges presented themselves. Steve - Excellent delivery of all the internal electrics required for the solution and thanks for the input relating to my battery questions. Nick - Excellent, super fast delivery of the outside works, including stripping and relaying of the roof tiles and deploying the solar panels as per the design. Dimitri - for the unending energy and enthusiasm supporting Nick in getting the outside works completed and for being probably the happiest person I've met in quite a while! The back office team for the timely turn around of issuing the energy export information to enable us to set up our outgoing tariff with Octopus. The ladies on the phones who always took care to ensure I was routed to the right people when I asked, taking messages and even helping to ensure skips and scaffolds were removed before Easter. Thanks again to you all - I was sitting here wondering when the last excellent customer experience I'd had, it must have been so long ago I can't think of one off the top of my head. Look forward to speaking to some of you again when we get started on Phase 2 - battery installation. D and K O'C.

After some hardware issues, EPC have provided some great service, especially when my carpet fitter stapled through the pipes!! Would recommend.

Customer focused; delivering excellent service and high quality installation. Had been let down by my previous installers; EPC configured an Air Source Heat pump and associated peripheral equipment that was correctly sized to meet the heating requirements for my home. Installation was completed in under two days by professional engineers Would highly recommend EPC Improvements.

Mark from EPC Improvements was really helpful when doing our first annual service of our air source pump, hot water cylinder and heating system. He answered all our questions and showed us how to get the system to work at its optimal best and potentially save money on our winter heating bills. We've already saved money on our energy costs since we had the air source pump installed, so that's great!

Frequently asked questions

How do I know you’re properly qualified and certified to install heat pumps?

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).

Can you tell me if a heat pump is actually suitable for my home?

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.

What type and size of heat pump will you recommend for my property, and why?

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.

What will the full installation cost be, and what’s included in your quote?

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.

Can you help me access government grants like the Boiler Upgrade Scheme?

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.

How much disruption should I expect during installation, and how long does it take?

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.

Will I need to replace my radiators or upgrade anything else in my home?

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.

How noisy is the outdoor unit and where will it be installed?

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.

What warranties, servicing and aftercare do you provide?

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.

What running costs and savings can I realistically expect compared to my current boiler?

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.
