Bulk EPC pricing explained: what drives the per-property rate

Access: where batch jobs actually go wrong

Almost every bulk EPC programme that overruns does so because of access, not assessment. Tenants not notified, keys not where the schedule says, agents unreachable on the day, blocks with fob-only entry: each failed entry burns a slot and needs a return visit. The fix is unglamorous and effective — a named access contact, a flat or property schedule with tenure and key location, advance notice to occupiers, and a planned mop-up visit for anything missed rather than a fresh booking cycle. When comparing quotes, ask directly how failed entries are handled and whether re-visits are chargeable, because that single answer often explains a large price gap.

• One named access contact for the batch, not one per property
• A schedule showing vacant, tenanted and key-held properties before survey days are set
• Advance notice to occupiers so entry is expected
• An agreed mop-up visit for missed properties, priced up front rather than after the fact

Deadlines and property mix

A flexible programme spread over a few weeks can be slotted around other work and priced accordingly. A hard lodgement deadline — a portfolio sale, a funding condition, a re-letting window — forces dedicated survey days and sometimes multiple assessors, and that costs more. Mix matters too: houses take longer than flats, commercial units need non-domestic accreditation and floor-area based assessment, and mixed residential and commercial batches need both capabilities on the same instruction. Where a batch spans both, confirm the provider actually holds domestic and commercial accreditation rather than subcontracting the commercial half to someone you never meet.

• Urgent lodgement deadlines require dedicated capacity and are priced higher
• Houses and HMOs take longer per property than uniform flats
• Commercial units need non-domestic assessment at the appropriate level
• Mixed batches should be handled under one instruction with both accreditations in place

How to compare bulk quotes properly

Put the quotes side by side and check they price the same job. Does each state a per-property rate, or only a total? Does the total assume every property is accessed first time? Are commercial units included at the same rate or excluded entirely? Is the lodgement date committed to in writing? Is the certificate lodged as each survey completes, or held until the batch finishes? Who owns the relationship if something is queried in eighteen months? These questions cost nothing to ask and reliably surface the difference between a genuine contract rate and a headline number designed to win the instruction and be renegotiated later.

• A stated per-property rate, not just a batch total
• Named extras: failed entries, added properties, commercial units, out-of-hours access
• A committed lodgement date and rolling lodgement as surveys complete
• A named assessor and a single point of contact after completion
