What landlords get with every subscription

EPC-focused

Designed to support EPC C outcomes in retrofit properties under the HaaS methodology.

Managed operation

Remote monitoring and optimisation through a connected cloud control platform.

Landlord-ready

Built for MEES compliance planning and property portfolio management at any scale.

No energy resale

Tenants keep their own electricity supplier. No supply arrangements to manage.

The challenge

Retrofit compliance is getting harder.

Many rental properties need a practical route to improved EPC performance without expensive plant rooms, wet heating systems or long-payback heat pump installations.

Understand MEES compliance

Heat pumps can require significant upfront capital that many retrofit landlords cannot justify.

Direct electric heating performs poorly in EPC assessments without a managed operational layer.

Landlords need clear evidence, controls and compliance documentation to satisfy inspectors.

Tenants need simple, reliable warmth — without complicated controls or energy system involvement.

Our approach

A managed heating service,
not just a product.

Our Heat-as-a-Service model adds an operational layer over the heating system — connecting approved controls, monitoring performance, optimising operation and providing EPC-focused support.

HaaS installation

Electric heating panels installed by approved engineers to the correct specification.

Approved control strategy

Certified smart thermostats and sensors configured to the HaaS operational specification.

Remote monitoring

Continuous system monitoring via a cloud-connected platform with real-time alerts.

Comfort optimisation

Heating schedules and setpoints adjusted remotely to maintain comfort and efficiency.

EPC assessment support

Evidence packs, service schedules and direct support for EPC assessors.

Ongoing service reporting

Regular performance and compliance reports for landlords and their advisors.

EPC methodology

Designed to support
EPC C in retrofitted properties.

Under the updated Heat-as-a-Service EPC methodology, HaaS can support EPC C outcomes in retrofitted properties when installed with the approved control strategy and operated as part of a managed Heat-as-a-Service arrangement.

Assessment outcomes depend on property fabric, occupancy, controls, installation and assessor inputs. This is not a guarantee of a specific rating.

Check your property

Approved controls

The system must include the approved thermostat and control strategy as specified under the HaaS methodology.

Managed operation

The system must remain actively connected to the monitoring and optimisation platform at all times.

Evidence pack

The property receives a service schedule, commissioning record and initial EPC assessment for assessors.

Ongoing support

Dedicated support for assessor queries, renewal assessments and portfolio compliance planning.

Landlord feedback

What our customers say

Landlords and portfolio managers across the UK trust HaaS to manage heating compliance.

"We activated 14 properties in a single afternoon. The address lookup is slick, the terms are clear and the EPC support has saved us thousands compared to what a heat pump rollout would have cost."

"The EPC evidence pack was the thing that convinced me. When the assessor came out, everything was documented, the controls were in place, and the assessment went smoothly. Genuinely impressive service."
