Electrical Estimating Services UK
Accurate, bid-ready electrical cost estimates for contractors, M&E subcontractors, and developers across the UK. Delivered within 10 to 48 hours. Following NRM2 and SMM7 methodology, aligned with BS 7671.
What Our Electrical Estimating Services Include
Electrical work is one of the more complex trades to price accurately. It's not just wiring. A properly structured electrical estimate covers every cost element from the distribution board through to testing and certification, and if you miss something at the estimating stage, you're carrying that loss through the whole project.
First fix electrical is all the work before plasterwork goes on. Cable routing through floors and walls, containment installation, back boxes, consumer unit mounting. It's the hidden infrastructure, and it's where most of the labour hours sit on a typical residential or commercial project.
Second fix picks up after the plasterer. Sockets, switches, light fittings, populating the consumer unit, final connections, testing. Contractors price first and second fix either as a combined package or separately depending on how the tender is structured. We work to whatever format you need.
Blaze Estimating is an independent third-party estimating firm, not an electrical contractor. We produce estimates structured around the regulatory framework your electricians work within. No conflicts of interest, no supplier relationships. Our construction estimating services cover every trade in the UK, electrical included.

First Fix and Second Fix
Priced separately or combined. Cable routing, containment, back boxes, consumer unit, sockets, switches, light fittings, final testing.

Cable tray, cable basket, trunking, conduit. Measured length by length with supports and fixings. A major commercial cost category, priced properly.
Distribution Boards and Sub-Distribution
Costed as individual items, not lump allowances. Board specification is priced in full on commercial and industrial jobs.
Testing, Commissioning and Prelims
All testing and commissioning costs included. Preliminary items applicable to the electrical package priced where scope requires it.
Residential, Commercial and Industrial Projects
We estimate electrical works across all project types and sectors. If your project has an electrical package, we price it.
Residential
New build houses, flats and apartments, extensions (single and double storey), loft conversions, basement conversions, full rewires. Covered within our residential estimating services. First and second fix priced separately or combined.
Commercial
Offices, retail units, restaurants, healthcare facilities, education buildings, multi-storey developments. See our full commercial estimating services for scope detail.
Industrial and Infrastructure
Warehouses, factories, manufacturing facilities, three-phase heavy plant, motor control centres. Priced as full schedules of quantities, not rule-of-thumb rates.
New Build
Complete electrical packages for new residential and commercial developments. Part L and Part P Building Regulations cost lines factored in as standard.
Fit-Out and Refurbishment
Landlord works, tenant fit-outs, phased commercial refurbishments. We account for the coordination costs and sequencing that come with occupied or phased programmes.
M&E Packages
Combined mechanical and electrical packages structured for M&E subcontractors. Delivered as one document or split by trade, depending on how the tender is structured.
Specialist Electrical Systems We Estimate
This is where a lot of estimating firms fall short. Basic power and lighting, yes. But fire alarms, emergency lighting, data cabling? Often an afterthought.
Each specialist system below is priced as a separate schedule within the estimate, not bundled into a lump allowance. That matters when your client or the main contractor starts asking questions about specific system costs.
We also cover EV charging infrastructure, which is now a standard cost line on new builds and commercial fit-outs, and solar PV with battery storage, particularly relevant under current Part L requirements. Building management system interface works are included where the scope requires it.

EV Charging and Solar PV
EV charging infrastructure and solar PV with battery storage. Increasingly required on new builds under Part L. Priced to current equipment rates.
Built Around UK Standards and Regulations
Electrical estimating in the UK isn't just about counting sockets. The regulatory framework matters and it affects cost. Every estimate Blaze produces is built around the standards your electricians work within.
NRM2 and SMM7
All estimates follow NRM2 and SMM7 measurement methodology. Structured cost output, consistently produced regardless of project type or size.
BS 7671 (18th Edition)
Cost lines reflect what BS 7671 Amendment 4:2026 compliant installation requires. RCD protection, AFDDs, SPD provision. Built in, not added later.
Part P and Building Regulations
Part P requirements factored into residential estimates. Notification and inspection fees included where applicable. No surprises at the certification stage.
Testing and Certification Costs
Testing and certification costs are standard line items in every estimate, not afterthoughts. Electrical Installation Certificates and EICRs costed in full.
Independent Position
Blaze is an independent estimating firm. We don't install or certify electrical work. Our estimates are structured around the framework your electricians operate within.
UK-Wide Coverage
Estimates produced for projects across England, Scotland, Wales, and Northern Ireland. London base, nationwide reach. Regional cost factors applied throughout.
From Drawings to Bid-Ready Estimate
We try to keep it as simple as possible for contractors who are already juggling bid deadlines. Three steps and you're done.
Send Your Drawings
Electrical layout drawings, schematics, panel schedules, specifications, and any specialist system requirements. Early-stage drawings are fine. We'll confirm what's achievable.
Quote in 10 to 15 Minutes
We get back with a quote for the estimating work within 10 to 15 minutes during business hours (9:00 AM to 9:00 PM). A real response from an estimator, not an auto-reply.
Estimate in 10 to 48 Hours
Full electrical takeoff completed, NRM2 and SMM7 methodology applied, line-by-line cost estimate delivered. Bill of materials, labour hours, and tender-ready summary included. Rush service available.
Why Electrical Contractors Outsource to Blaze
The honest answer is time. Electrical estimating is slow work, especially on commercial jobs. Most electrical contractors don't have the in-house capacity to price complex tenders and keep current projects running at the same time.
Capacity Without Headcount
Outsourcing solves the capacity problem. You send us the drawings, we price the job, you review and submit. Your team stays focused on delivering the work you've already won.
Accuracy That Protects Margin
A mispriced electrical tender costs you in one of two ways: underbid and lose margin, overbid and lose the contract. At 95% accuracy across 6,000+ projects, we don't get that wrong very often.
Up to 20% More Tender Wins
Clients report up to a 20% improvement in tender win rates after working with us. That's the kind of result that makes the cost of outsourcing look pretty straightforward.
Fully Confidential Service
Your drawings, your pricing strategy, your project details stay between you and us. Blaze operates as an independent, confidential third-party estimating firm.
Genuinely Independent
No relationship with material suppliers, electrical contractors, or systems manufacturers. The estimate reflects actual cost, not a preferred pricing arrangement.
UK-Wide From Central London
We work on projects across England, Scotland, Wales, and Northern Ireland. 15+ years of UK construction estimating experience, 9+ estimators on the team. Electrical estimates regularly sit alongside groundwork packages in the same tender.
