Surveys, energy models and evidence that works for you.
Seren Surveying works for homeowners, landlords, estate agents, rural estates, housing providers, coordinators and installers across Wales and the South West of England.
Your properties on the register
Tick the homes you own or manage. The register lists every home at a postcode, not just yours.
| Yours | Address | Rating | Lodged | Heating | Certificate |
|---|
EPCs can be out of date or wrong. A certificate lasts ten years, and the register only shows what the last assessor recorded. Treat this as a starting point, not a verdict. Scheme figures checked 20 October 2026.
Take the register with you
Keep what you have ticked. It arrives by email as a PDF within minutes.
The summary table and what the register implies for your homes: the 2030 standard, expired certificates, the heat pump grant.
A page for each home: walls, roof, floor, windows, heating and hot water as the register records them, the measures it lists with its indicative costs and the rating each would reach, and what we would look at on a visit. £3 a home for the first 10, £2 from 11 to 50, £1 above that.
What we do
Retrofit assessments and EPCs
PAS 2035 retrofit assessments, RdSAP modelling and lodged EPCs, with floor plans where they are needed. One visit, one report you can act on.
Modelling before you commit
Pre- and post-improvement models, funding viability, variance and exemption evidence. We tell you whether a job stacks up before anyone spends money.
Portfolio and estate surveys
The whole stock looked at together: what each property needs, what it will cost, what funding exists, in an order you can budget for.
Compliance support for coordinators and installers
Audit-fail reviews, evidence packs, supplier-query responses, and the assessment groundwork for designs that a qualified Retrofit Coordinator signs off.
How a job runs
Survey and evidence
A site survey with the occupier present, with the measurements and photographs that will stand up later.
Model and cost, pre and post
The property as it is and as it would be after the works, with each measure priced.
Options and priorities you can budget
What to do first, what can wait, and which funding applies to which measure.
Design and coordination with a qualified RC
Coordination and designs are signed off by the chartered Retrofit Coordinator we work with. Seren does the assessment, the modelling and the groundwork.
Install evidence and an audit-ready file
Evidence gathered through the works and filed so that an audit finds what it needs.
Track record
I listen to the occupier's concerns, explain findings plainly and plan work with their circumstances in mind. Gaining trust and keeping people informed matter as much as getting the technical recommendations right. I understand how measures affect one another, and the importance of addressing the underlying cause rather than the symptom.
