Frequently Asked Questions

What services do EPEC Ltd offer?

EPEC Ltd which is short for 'Energy Performance Efficiency and Cost savings'

We offer a range of energy and building related assessment and surveying services aimed at giving homeowners the best advice on how to reduce their energy usage and make home improvements. These are: 

  • Sunamp UniQ Heat battery installation
  • Domestic EPCs
  • Architectural design and specification.
  • Retrofit energy assessments under PAS 2035. 
  • Building Surveying services. 
What is a Sunamp UniQ Heat battery?

A Sunamp UniQ Heat Battery is a renewable technology that replaces old inefficient hot water cylinders (both vented and unvented) with an A+++ energy rating. 

These 'charge' using electricity from your mains supply at cheap overnight rates, from solar panels and/or battery storage. 

The stored heat is released when you switch your hot tap on to wash in a sink, bath or shower just liek a combi boiler does. 

These are much smaller than hot water cylinders so allow for much more storage and living space. 

What are our EPC services?

We offer domestic EPCs at a reasonable cost (from £50.00) with short lead times (often within 48 hours) from quotation to booking, site survey, calculations and production of the EPC.

Using our range of skills, qualifications, knowledge and experience, we aim to give homeowners a high quality service which will meet their specific needs. This ranges from getting an EPC completed to designing a brand new extension for your home.
