MEPS and Condominium Buildings

Condominium buildings, where individual units are owned separately and common parts such as roofs, facades, stairwells and heating systems are owned collectively, raise MEPS questions that single-owner buildings do not. Energy performance depends on both unit-level features, such as windows and heating controls within a flat, and common features, such as roof insulation, facade insulation and central heating. A MEPS regime must therefore decide its unit of assessment, whether the whole building, each unit, or both, and its duty holder, whether the owners collectively, individual owners, or a management body, and those decisions shape everything that follows.

Collective decision-making is the central practical challenge. Improving common parts usually requires agreement among owners, often by a qualified majority under condominium law, and funding through service charges or special levies. Owners may disagree about priorities, costs, disruption or the choice of measures, and a minority that opposes work can delay or block a package that the majority supports, depending on the voting rules. MEPS trajectories that assume collective action without addressing voting and funding rules will stall in such buildings, however sound their energy logic.

Assessment also raises questions. A whole-building certificate may describe common performance, while unit certificates describe individual flats, and the two can tell different stories: a well-insulated top-floor flat in a poorly insulated block, or a ground-floor flat with a cold floor in an otherwise improved block. A MEPS floor applied at whole-building level, at unit level, or at both levels will therefore affect different owners differently, and an owner should check which level applies before assuming a building's or a unit's position.

Funding and cost allocation add a further layer. Common works are typically funded collectively, but the allocation formula, whether by floor area, by unit share, or by benefit, affects who pays how much, and owners of already-improved units may resist paying for common works that benefit others more. Transparent cost-benefit information, staged programming and, where available, external funding for common works can ease those tensions, but they do not remove the need for agreement.

For an owner or manager, the practical steps start with structure: obtain the condominium documents, identify common parts and their condition, and check the MEPS unit of assessment and duty holder in the national measure. Then commission a whole-building assessment that separates common and unit measures, and present a staged package with costs allocated transparently. Early engagement with all owners, with clear information about benefits, costs and disruption, gives collective decisions their best chance.

For a buyer of a condominium unit, the MEPS check should cover both levels: the unit certificate and the whole-building position, including any planned common works, service charge implications and pending decisions. A unit that meets a floor today may face a future levy for common works, and a unit that does not meet a floor may be improved by common works already planned. Both facts affect value and should be understood before purchase.

By place, condominium law varies greatly, from detailed condominium statutes with strong management bodies to looser co-ownership arrangements with minimal formal governance. MEPS implementation must fit that law, and national measures address multi-apartment buildings in different ways, from whole-building renovation programmes to unit-level standards. A reader should therefore check both condominium law and MEPS law for the country concerned, together.

In the UK, flats are typically held on long leases with a freeholder or management company responsible for common parts, rather than under condominium law as such, but the collective decision and cost allocation questions are closely analogous. Lease terms, service charge provisions and management arrangements should be checked alongside any energy standard that applies to flats.

A common mistake is to assess only the unit or only the whole building, and to miss the other level's MEPS position. Another mistake is to plan common works without checking voting rules and funding, and then to discover that a technically sound package cannot be agreed or funded.

A further mistake is to allocate common costs without transparency, leading to disputes that delay work and damage neighbour relations. Clear, unit-by-unit cost and benefit information, even where the allocation formula is fixed, reduces that risk.

Keep the condominium documents, whole-building and unit certificates, staged package, cost allocations and meeting decisions together. That file supports future decisions, sales and any query about what was agreed and funded.

Questions to ask include: what is assessed, whole building or unit, who decides common works and by what majority, and how are costs allocated. Those questions define a condominium MEPS position.
