EPC Tywyn. Domestic & Commercial Energy Performance Certificates (EPC), without the fuss.

Domestic & Commercial Energy Performance Certificates (EPC) Tywyn

We provide EPCs in Tywyn and across Gwynedd for both Domestic and Commercial properties. A valid EPC is required to be in place before the sale or rental of your property. The EPC survey itself is entirely non intrusive and won't damage the building in any way. Once the survey is complete the EPC report will be produced, which gives the building an Energy Performance Rating rating on a scale from A to G.

For most rental properties an EPC rating of E or better is required, in compliance with the Minimum Energy Efficiency (MEES) legislations of 2018. For properties for sale, MEES legislation does not yet apply, however an ever increasing number of financial institutions require properties to demonstrate they would be MEES compliant before agreeing mortgage funding.

Across Tywyn, the most common domestic EPC band is D, with 31% of homes rated C or above and an average energy-efficiency score of 58 out of 100. Commercial properties in the wider Gwynedd area have an average rating of C 73 (UK average D 77).

There is real room to improve: the average Tywyn home could raise its score by about 25 points, and 84% could improve by 10 points or more. The average home here emits roughly 5.4 tonnes of CO₂ a year.

Around 70% of homes in Tywyn are owner-occupied and 16% are privately rented. About 50% are houses and 15% flats, and 58% are heated by mains gas. On the fabric, 54% have insulated cavity walls and 88% are fully double-glazed or better.

Letting a property in Tywyn? About 76% of privately rented homes here are rated below an EPC C, the level the government has proposed as a future minimum for rented homes, and 10.1% are rated F or G, below the EPC E minimum needed to let a home today. We can carry out the EPC and advise on the most cost-effective way to improve the rating.

New-build makes up about 5% of certificates in Tywyn, averaging a band B. New builds need a SAP calculation and an as-built EPC, both of which we provide.

These figures are from analysis of 1,623 domestic EPCs lodged for Tywyn in the publicly available government data set, current to 2026-05-31. Values are medians/averages from the source data.

For properties for which we have produced an EPC in Tywyn, if shown not to meet MEES targets, we can then provide tailored advice on the least disruptive and most cost effective ways to improve the building to achieve the targeted rating. We are happy to provide more in depth MEES advice, including on MEES Exemptions so please Contact Us for more information.

Commercial EPCs

Carried out by one of our fully accredited Non-Domestic Energy Assessors (NDEA), the Commercial EPC survey will look at the way the property is constructed, conditioned (including for water heating), insulated, ventilated and lit. It also takes into account the different activities that take place within each zone of the property.

The Commercial EPC survey is entirely non invasive. The assessor will not drill any holes or unscrew any access panels. Any elements of the building and its systems that cannot be visually inspected during the site visit can also be accounted for by documentary evidence. In order to achieve the most accurate rating, you can provide in advance, or make available on the day, any documentation you may have relating to the construction of the building and the make and model of any HVAC systems, lighting designs etc.

For any elements of the building that can not be visually inspected or evidenced by documentation, a set of default assumptions have to be made. These assumptions use ‘worse case scenario’ default values, and as such can lead to a worse EPC rating. The Commercial EPC process does not take into account energy used by commercial processes taking place within the building, such as manufacturing, food preparation etc, to allow a fair comparison between buildings. more information.
