Retrofit, damp reports and EPCs across London

  • Cold rooms.

Most people are told to wipe the mould, turn the heating up, or replace one thing at a time. We find what’s actually driving the problem — then help you put the home right, properly.

ii.About us

We treat the building as a system, so interventions solve the root cause rather than create new ones.

Technical clarity you can act on

Alpha Performance Solutions Ltd provides damp and mould surveys, EPCs, landlord compliance support and retrofit coordination across London and Dartford (DA postcodes). We combine technical expertise with hands-on site experience. Femi Adeoye holds the ABBE Level 5 Diploma in Retrofit Coordination and Risk Assessment.

Most retrofit and moisture problems are treated in isolation. We treat the building as a system — protecting fabric, improving energy performance, and safeguarding occupant health.

  1. Evidence-based reportingDocumentation that stands up to scrutiny from local authorities and insurers.
  2. London knowledgeDeep experience with solid-wall and multi-tenure housing stock.
  3. Long-term performance focusWe prioritise lasting outcomes over short-term cosmetic fixes.

iv.FAQ

Common questions

Short answers to the questions we hear most often. Something else? The simplest way is WhatsApp or a short call.

What is retrofit coordination by a Level 5 qualified Retrofit Coordinator?

Retrofit coordination takes a whole-house approach to domestic retrofit. Coordination means assessing the building as a system, identifying risks (including moisture and ventilation), and producing a clear, sequenced improvement plan rather than isolated measures.

Do you only work in London?

No. We’re based in Greenwich and cover all of London, plus Dartford and other DA postcodes.

What does a damp and mould report include?

A root-cause focused assessment of moisture issues, consideration of ventilation and cold surfaces, and a clear, prioritised list of recommended actions. Reports are written so landlords and homeowners can act on them.

What landlord certificates can you provide?

We provide EPCs, inventory and condition reports, and damp & mould reports for rented properties, and arrange electrical installation condition reports (EICRs) through our partner qualified electricians. Call or WhatsApp with the property address and what you need for a clear next step.

Do you support social landlords under Awaab’s Law?

Yes. We provide technical inspection, root-cause investigation, reporting, remedial planning and post-remediation verification for housing associations, local authorities, ALMOs and housing delivery partners. See our Awaab’s Law page for the full technical response pathway.

Can you help improve an EPC rating?

We provide guidance on what drives an EPC score and realistic improvement pathways. Better ratings should follow genuine fabric and system improvements. We link this advice to wider retrofit planning where appropriate.

How do I get started?

The simplest way is WhatsApp or a short call. Tell us the property address and what you need (retrofit advice, damp report, EPC guidance, inventory or remedial works). We’ll outline the next step.

Do you carry out the building works yourselves?

We provide assessment, specification and delivery of remedial works, and we coordinate and plan energy upgrade works. APS is your single point of contact, providing the technical lead, a clear scope and quality oversight.

Do you help with heat pumps and solar?

Yes. We start with a free home energy check and a clear written proposal across London and Dartford (DA postcodes). We work with MCS-certified installers, who quote, fit and certify the work directly with you. See our heat pumps & solar page.
