London homes Root-cause first

Cold rooms. Mould that keeps coming back. Bills that won’t come down.

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.

Technical clarity you can act on

Alpha Performance Solutions Ltd is an independent PAS 2035 Retrofit Coordination consultancy based in London. We combine technical expertise with hands-on site experience.

Most retrofit and moisture problems are treated in isolation. We treat the building as a system so that interventions solve the root cause rather than create new ones — protecting fabric, improving energy performance, and safeguarding occupant health.

Common questions

Short answers to the questions we hear most often.

What is PAS 2035 retrofit coordination?
PAS 2035 sets out 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?
Yes. We are based in London and focus on properties across the capital. That keeps our knowledge of local housing stock practical and relevant.
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 landlord compliance documents for rented properties, including EPCs, electrical condition reports (EICR), inventory and condition reports, and damp & mould reports. 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 independent technical inspection, root-cause investigation, reporting, remedial planning and post-remediation verification for housing associations, local authorities, ALMOs and housing delivery partners. See our dedicated 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 and energy upgrade works. You deal with APS for the full process — technical lead, clear scope and quality oversight — not a chain of separate companies.
